Association between body condition profiles, milk production and reproduction performance in Holstein and Normande cows

Body-condition dynamics are known to affect the different steps of reproduction in cattle (cyclicity, estrus expression, fertilization, embryo development). This has led to a widespread idea that there is an ideal-target optimal body condition, but no clear profile has yet been identified. Here we investigated the relationships between body condition score (BCS) profiles and reproductive performance in dairy cows. Data were from Holstein or Normande herds in 6 French experimental farms. In the Holstein breed, we discriminated 4 BCS profiles based on combining BCS at calving (Low: around 2.6 points, or High: around 3.3 points) with BCS loss after calving (Moderate (M): ≤ 1.0 points, or Severe (S): > 1.0 points). The Low-M profile mostly included multiparous cows with higher milk yield and lower reproductive performance than cows in the 3 other profiles. Low-M cows that experienced abnormal ovarian activity had lower reproductive performance than their profile-mates. Moreover, 67% of Low-M cows kept the same profile at the following lactation. The High-S profile mostly included primiparous cows with lower milk yield and higher reproductive performance than cows in other profiles. In High-S cows, higher milk yields correlated to higher risk of failure to calf on first insemination. Moreover, 38% of High-S cows kept the same profile at the following lactation, and none changed to Low-M. The other 2 BCS profiles (Low-S and High-M) were intermediate in terms of milk yield and reproductive performance. In Normande, we discriminated 3 BCS profiles based on combining BCS at calving (Low: around 2.6 points, or High: around 3.5 points) with BCS loss after calving (Flat (F): flat with no loss, Moderate (M): around 0.5 points, or Severe (S): around 1.0 point). The Low-M and High-S profiles included cows with similar performance, even though High-S-profile cows showed better but not significantly different milk yield and reproduction performance. The High-F profile included cows that were more likely to experience abnormal ovarian activity and fail at first insemination than cows in other profiles. More than 50% of Normande cows with 2 successive lactations kept in the same BCS profile at the next lactation. Even though a low BCS at calving combined with severe BCS loss (more than 1 point) after calving was found to increase reproductive failure, there was no evidence of an optimal BCS profile for reproduction in dairy cows, and reproductive success or failure is multifactorial.

Association of meleanocortin 4 receptor gene polymorphism (MC4R:C.92C>T) with feline diabetes

Objective: Diabetes mellitus (DM) is a prevalent endocrine condition found in cats. Recent research has identified a connection between a higher risk of diabetes in cats and genetic factors. This genetic susceptibility to type 2 diabetes is associated with genes that control insulin secretion and function, as well as those that impact factors like obesity. The purpose of the study was to determine the prevalence of the melanocortin 4 receptor (MC4R) gene missense mutation among cats and to investigate the relationship between body condition score (BCS) and the occurrence of diabetes in felines. Materials and Methods: Genotype analysis was done for 45 samples. The research results were obtained with the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. The 1,200-bp PCR product was cut with BstOI restriction enzyme. Results: Upon analyzing the data, it was found that 37.8% (n = 17) of the subjects carried the MC4R gene mutation. Across the entire population of cats studied, the C allele associated with the mutation was most prevalent in the group of cats with DM (frequency of 0.3) and least common among the clinically healthy cats (frequency of 0.2). Conclusion: After analysis of the study results, a statistically significant difference was observed between cats with DM and clinically healthy cats in the comparison of their BCS (p < 0.05). The association of the MC4R gene polymorphism with overweight and the development of diabetes has been identified.

Relationship of Body Condition Score at Calving with Animal Weight and some Measurements Udder in Holstein Cows

The Great Diwaniyah cows station, at the southern entrance of Al-Dagarah district in Al-Diwaniyah Governorate, was the study’s location from 6/12/2021 to 25/2/2023. It examined the relationship between body condition score (BCS) and animal weight and udder measurements in Iraqi-bred Holstein cows. The 50 cows in parity2 were divided by body condition at calving into three groups (BCS1 = 2.5-3 point (17 cows), BCS2 = 3-4 point (20 cows), and BCS3 = 4 -5 point (13 cows)) based on 1-5 point scal. They were milked twice a day, morning and evening, by an automatic milking machine. BCS3 group had significantly higher body weight at calving (477.15 kg) and peak lactation (413.92 kg) (P≤0.01) compared to BCS2 group (429.55 kg) and BCS1 group (382.55 kg) (P≤0.01). Examining the link between body condition score (BCS) and udder measures before milking, BCS1 group exhibited a significant (P≤0.05) udder elevation of 67.70 cm compared to BCS2 group at 63.52 cm. No significant differences were seen between these two groups and BCS3, which reported 65.57 cm. In the BCS2 group, the average length of the anterior nipples was substantially longer (P≤0.01, 7.87 cm) compared to the other two groups. In BCS2, the average length of posterior nipples was substantially longer (P≤0.01) at 6.95 cm compared to 6.15 cm in BCS1. The average distance between the front and posterior nipples in the three groups did not differ significantly. Compared to BCS2 group, BCS1 group had substantially greater udder height (69.08 cm) from the ground (P≤0.05) compared to BCS2 group (66.12 cm). No significant difference was seen between these two groups and BCS3, which was 67.36 cm. The average length of the anterior nipples was significantly shorter (P≤0.01) in the BCS2 group (6.97 cm) than in the BCS3 or BCS1 groups. The BCS3 group had a significantly longer average length (6.56 cm) than the BCS1 group (6.07 cm). The BCS2 group had a significantly longer average posterior nipple length (6.22 cm) compared to the BCS1 group (5.61 cm) (P≤0.05). The average posterior nipple length was similar in BCS2 and BCS1 groups and BCS3 group. The average distance between the front and posterior nipples in the three groups was not significantly different. The BCS2 group had a significantly higher difference in udder height before and after milking (P≤0.01) compared to BCS3 and BCS1, with a difference of 2.60 cm compared to 1.78 and 1.38 cm, respectively. In the BCS2 group, the average length of the anterior nipples decreased significantly (P≤0.01) after milking, reaching -0.895 cm compared to the BCS1 and BCS3 groups (-0.517 and -0.623 cm, respectively). The BCS2 group showed a substantial (P≤0.01) decrease in hind nipple length after milking, with a decrease of -0.730 cm compared to BCS1 and BCS3, which showed -0.535 and -0.569 cm, respectively. After milking, the BCS2 group showed a substantial reduction (P≤0.01) in the distance between the front and posterior nipples compared to BCS1 or BCS3 groups. The study shows that physical condition affects animal weight and several udder parameters during calving.

Relationship of Body Condition Score at Calving with Reproductive Performance, some Blood Metabolites and some Pathological Conditions in Holstein Cows

The study was conducted at The Great Diwaniyah cows station, located at the southern entrance of Al-Dagarah district - Al-Diwaniyah Governorate, from 6/12/2021 to 25/2/2023, to examine the relationship between body condition score (BCS) and reproductive traits, blood biomarkers, and metabolic diseases in Iraqi Holstein-Friesian cows. The 50 cows in parity2 were divided by body condition at calving into three groups (BCS1 = 2.5-3 point (17 cows), BCS2 = 3-4 point (20 cows), and BCS3 = 4 -5 point (13 cows)) based on 1-5 point scal. They were milked twice a day, morning and evening, by an automatic milking machine. The study found a substantial decrease (P≤0.01) in days open for BCS1 (77.18 days) compared to BCS2 (84.05 days) and BCS3 (88.23 days). The BCS2 group had considerably fewer days available (P≤0.01). Compared to BCS3. The study found a significant decrease (P≤0.01) in inter-calving interval for BCS1 group (354.59 days) compared to BCS2 and BCS3 groups (360.95 and 365.69 days, respectively). BCS2 group showed considerably shorter duration (P≤0.01) compared to BCS3 group. The study found no significant influence on inseminations per pregnancy or pregnancy length in the three cow groups. The study found that the BCS2 group had significantly higher glucose concentration (62.19 mg/100 ml) post-calving compared to BCS3 group (57.86 mg/100 ml), but BCS1 group did not differ significantly (59.30 mg/100 ml). The study found a substantial rise (P≤0.01) in BHB concentration (0.922 mmol/L) in the BCS3 group compared to BCS2 and BCS1 (0.743 and 0.674 mmol/L, respectively). BCS3 group showed a substantial increase (P≤0.01) in NEFA concentration (0.590 mmol/L) compared to BCS2 and BCS1 groups (0.476 and 0.461 mmol/L, respectively). During peak production, BCS2 group had a significant increase (P≤0.05) in glucose concentration (64.04 mg/100 ml) compared to BCS3 group (58.97 mg/100 ml), while BCS1 group did not differ significantly (60.97 mg/100 ml). BCS3 group showed a substantial increase (P≤0.01) in BHB concentration (0.434 mmol/L) compared to BCS2 and BCS1 groups (0.297 and 0.318 mmol/L, respectively). The study found a substantial increase (P≤0.01) in NEFA concentration in the BCS3 group (0.290 mmol/L) compared to BCS2 and BCS1 (0.205 and 0.215 mmol/L, respectively). The study found a significant (P≤0.05) increase in ketosis in Holstein cows with BCS2 and BCS3 groups, with rates of 1 (5.0%) and 2 (15.38%), respectively, compared to the BCS1 group with no injury. No significant changes were seen in placental retention, metritis, mastitis, and neonatal mortality between cows. According to the study, bodily condition during calving is linked to reproductive features, blood metabolites, and disease infection in cows.

Relationship between body condition and vertical movement symmetry in 109 riding school horses

Abstract For riding schools, the health and function of their horses is paramount. Unfortunately, lameness and overweight are common problems in this population, and a causal relationship whereby increased body weight causes lameness is also possible. This observational field study investigated the relationship between body condition score (BCS) and motion movement asymmetries in riding school horses and also explored the relationships between BCS, movement asymmetry and subjectively scored willingness to work. Eight riding schools within 2.5 h by car from Uppsala, Sweden, were convenience-sampled and 3-24 horses from each were included in the study. Body condition was scored (scale 1-9) and vertical movement asymmetry data were collected in straight-line trot, using an inertial measurement unit system. Asymmetry parameters were calculated as the mean difference between local vertical displacement minima/maxima for the head/pelvis (HD/PD) between the two halves of the stride. A questionnaire was used to assess perceived willingness to work and energy level of the horses. The data were analysed with linear mixed models, t-tests and Mann-Whitney U-tests. A correlation was found between BCS and PDmin (), an asymmetry parameter related to hindlimb weight-bearing lameness, where PDmin increased by 0.96 mm for each unit increase in BCS. Horses with vertical movement classified as symmetric had lower BCS than horses with movement classified as asymmetric (5.4 ± 0.4 vs 5.7 ± 0.6, ). Horses classed as overweight (BCS ≥ 6) scored lower on willingness to work () and energy level (). These results indicate that the body condition of riding school horses may influence their function and the health of their locomotor apparatus. Further studies are required to identify the underlying mechanisms.

Genetic associations of ewe body condition score and lamb rearing performance in extensively managed meat sheep

Many small ruminant production systems are relatively low input and rely heavily on animals grazing pastures often in extensive and harsh environmental conditions, unsuitable for any other type of agriculture. New breeding goal traits for lifetime resilience for maternal sheep breeding programmes have been investigated, focusing on body tissue mobilisation phenotypes and their genetic relationships with maternal production traits. Performance records of 8,355 Scottish Blackface ewes, from 2 extensively reared hill sheep flocks, collected over a 20-year period, were used to quantify relationships between body condition score (BCS) and the ewe's ability to successfully rear lambs. Between 14,000 and 25,000 data records per trait were available, measured across the annual sheep reproductive cycle. The pedigree file used for the analyses included sire and dam information for 50,207 animals. Most heritability estimates for the BCS traits - measured at key time points within the annual production cycle, or considering BCS changes between time points - were low, but significantly different from zero, ranging between 0.07 and 0.17. The heritability estimate for the number of lambs at pregnancy scanning was 0.09. Heritabilities for foetal loss from pregnancy scanning to lambing, lamb loss from lambing to weaning and number of lambs weaned were 0.02, 0.02 and 0.06, respectively. These estimates indicate that genetic control over the reproductive and lamb survival traits (expressed as a trait of the dam), is lower than that for BCS (and BCS changes) over the reproductive cycle. The genetic relationships amongst the BCS of ewes at pre-mating, pregnancy scan and at pre-lambing, with litter size at pregnancy scan and number of lambs weaned, were consistent. They indicate that ewes of higher body condition score (potentially over-fat, within the range recorded in these flocks) conceive, and rear, fewer lambs, with genetic correlations ranging between -0.18 and -0.58. However, post-weaning, animals with genetic propensity for greater gain in BCS from weaning to pre-mating produce larger litters and rear more lambs. In addition, the selection of ewes that lose less condition during pregnancy will reduce foetal losses. The results from this study paint a complex picture that should be interpreted in the context of specific management practices for extensively managed hill sheep, at critical times in their reproductive cycle. The traits relating to body tissue mobilisation, as assessed using BCS, are mostly heritable and their inclusion in future breeding programmes, to aid future selection for resilience, should be considered.

Association between body condition score, testicular haemodynamics and echogenicity, nitric oxide levels, and total antioxidant capacity in rams

Higher body fatness adversely affects metabolic and hormonal homeostasis. The present work aimed to evaluate the association between body condition score (BCS) and haemodynamic pattern and echogenic appearence of the testes as well as nitric oxide (NO) levels and total antioxidant capacity (TAC). For that, fifteen Ossimi rams were blocked according to their BCS into a lower BCS group (L-BCS:2–2.5; n = 5), medium BCS group (M-BCS:3–3.5; n = 5), and higher BCS group (H-BCS:4–4.5; n = 5). Rams were examined for testicular haemodynamics (TH; Doppler ultrasonography), testicular echotexture (TE; B-mode image software analysis), and serum levels of NO and TAC (colorimetric). Results are presented as means ± standard error of the mean. There was a significant (P < 0.05) difference in the resistive index and pulsatility index means among the groups under experimentation, being the least in the L-BCS group (0.43 ± 0.02 and 0.57 ± 0.04, respectively) compared to the M-BCS (0.53 ± 0.03 and 0.77 ± 0.03, respectively) and H-BCS rams (0.57 ± 0.01 and 0.86 ± 0.03, respectively). Among blood flow velocity measurements [peak systolic, end-diastolic (EDV), and time-average maximum], only EDV showed significant (P < 0.05) higher values in the L-BCS group (17.06 ± 1.03 cm/s) compared to M-BCS (12.58 ± 0.67 cm/s) and H-BCS (12.51 ± 0.61 cm/s) groups. Regarding the TE results, there were no significant differences among the examined groups. There were significant differences (P < 0.01) in the concentrations of TAC and NO among the groups under experimentation, in which the L-BCS rams had the highest levels of TAC and NO in their sera (0.90 ± 0.05 mM/L and 62.06 ± 2.72 μM/L, respectively) than the M-BCS (0.058 ± 0.05 mM/L and 47.89 ± 1.49 μM/L, respectively) and H-BCS rams (0.45 ± 0.03 mM/L and 49.93 ± 3.63 μM/L, respectively). In conclusion, body condition score is associated with both testicular hemodynamic and the antioxidant capacity in rams.

Association between Birth Weight and Subcutaneous Fat Thickness at Adulthood in Dogs

Overweight affects nearly 40% of dogs. The objective of this study was to explore the hypothesis of the Developmental Origins of Health and Disease through the association between birth weight and adiposity in adult dogs. The association between body condition score (BCS) and subcutaneous fat thickness (SFT), measured in the flanks, abdomen and lumbar regions, was assessed in a population 88 adult Labradors (>1 year). Significant positive moderate correlations between BCS and SFT were described. A linear mixed-effects model was used to investigate the association between birth weight and SFT by adjusting for sex, age, neuter status and the anatomical site of the measurement. The results showed that SFT values increased with age and were higher in sterilized than in entire dogs. In addition, SFT values were higher in the lumbar region compared to the other anatomical sites. Finally, the model revealed a significant association between SFT and birth weight, suggesting that, as in other species, dogs with the lowest birth weights have thicker subcutaneous fat at adulthood than the others. The assessment of visceral adipose tissue and the relative importance of birth weight among the numerous risk factors of overweight remains to be explored in dogs.

Association between body condition score fluctuations and pregnancy loss in Holstein cows.

The objective of this study was to characterize the associations between body condition score (BCS) and BCS change (∆BCS), determined by an automated camera system during early lactation and close to artificial insemination (AI), and the subsequent pregnancy loss (PL) in Holstein cows. A secondary objective was to determine the impact of disease on PL, considering multiple time periods relative to AI. Data from 9,430 lactations in 6,884 Holstein cows in a commercial dairy operation located in Colorado, USA were included in this retrospective observational study. Cows were subject to first AI at about 80 DIM (primiparous) and 60 DIM (multiparous), following a double OvSynch protocol. Pregnancy diagnosis was performed via transrectal ultrasonography on day 32 ± 3 after AI and reconfirmed on day 80 ± 3 after AI. Cameras mounted on the sorting gate at each exit (n = 2) of the milking parlor generated BCS on a five-point scale with 0.1 increments. The BCS at calving (BCS1), 21 DIM (BCS21), 56 DIM (BCS56), AI resulting in pregnancy (BCSAI), and 90 d post AI (BCSAI90) were selected for the analyses and subsequently categorized as low (≤ lower quartile), moderate (interquartile range), and high (≥ upper quartile). Changes in BCS were calculated by periods of interest as change from calving to 21 DIM; change from calving to 56 DIM; change from 56 DIM to AI; and change from AI to 90 d post AI and assigned into categories to facilitate the analysis. Data were examined using logistic regression, considering parity category, season at calving and AI, DIM at AI, milk yield up to 60 DIM, and occurrence of disease as covariables. The logistic regression analyses indicated that the odds of PL were greater in cows in the low BCS category relative to cows in the high BCS category at 56 DIM (OR 95% CI = 1.41 [1.12-1.79]), AI (1.31 [1.05-1.65]), and 90 d post AI (1.38 [1.10-1.74]). Likewise, cows with large loss in BCS between calving and 21 DIM (1.46 [1.10-1.94]) and loss in BCS between AI and 90 d post AI (1.44 [1.15-1.81]) had greater odds of PL compared with cows with no loss of BCS within the same period. Occurrence of disease at all the time periods considered in the analysis had a consistent detrimental impact on maintenance of the pregnancy, supporting the concept that pre and postconceptional disease affects embryonic survival. Overall, low BCS, more pronounced reductions in BCS occurring closer to AI, and occurrence of disease resulted in greater PL in this Holstein population.

Dynamics of automatically generated body condition scores during early lactation and pregnancy at first artificial insemination of Holstein cows

The objective of this study was to characterize the association between body condition score (BCS) and BCS change (ΔBCS), determined by an automated camera system at multiple time points, and the subsequent pregnancy per first artificial insemination (P/AI1) of Holstein cows. A retrospective observational study was completed using data collected from 11,393 lactations in 7,928 Holstein cows calving between April 2019 and March 2021 in a commercial dairy operation located in Colorado. Cows were classified as primiparous or multiparous. Scores generated by BCS cameras at dry-off, calving, 21 days in milk (DIM), 56 DIM, and first artificial insemination were selected for the analyses and subsequently categorized as low (≤lower quartile), moderate (interquartile range), and high (≥upper quartile). Changes in BCS were calculated by periods of interest as change from dry-off to calving (multiparous cows); change from calving to 21 DIM; change from calving to 56 DIM; and change from calving to first artificial insemination and assigned into categories as large loss of BCS (top 25% of cows losing BCS); moderate loss (bottom 75% of cows losing BCS); no change (ΔBCS = 0); or gain of BCS (ΔBCS > 0). Data were examined in primiparous and multiparous cows separately using logistic regression and time-to-event analyses. Initial univariable models were followed by multivariable models that considered calving season, occurrence of disease, and milk yield up to 60 DIM as covariables. The logistic regression analyses indicated that in both parity groups the associations between BCS category and P/AI1 were more evident at 21 DIM, 56 DIM, and first artificial insemination, with lower odds of P/AI1 in cows in the low BCS category. Likewise, cows with large loss in BCS between calving and 21 DIM, calving and 56 DIM, and calving and first artificial insemination had lower odds of P/AI1 compared with other categories of ΔBCS within the same period of interest. Similarly, survival analyses evidenced that cows in the low BCS category required more time to get pregnant. In agreement, differences in the dynamics of the average daily BCS during the first 90 DIM were evident when cows were grouped by first AI outcome (pregnant vs. nonpregnant) and by their time to pregnancy category (<90 DIM; 91-150 DIM; or >150 DIM), with cows with reduced fertility showing lower BCS up to 90 DIM. Overall, low BCS and more pronounced reductions in BCS occurring closer to first artificial insemination resulted in lower odds of pregnancy per artificial insemination.

A Study on Relationship between Body Condition Score (BCS) and Milk Yield, Fat and Solids-Not-Fat Percent in Murrah Graded Buffaloes under Field Conditions

The present experiment was a study on the relationship of Body Condition Score with milk yield, fat and solids-not-fat percent in murrah graded buffaloes under field conditions. In this murrah graded buffaloes from different commercial farms of Guntur and Krishna districts were selected. Total of 150 murrah graded buffaloes of different parities (1st to 6th parities) were selected. Various parameters like BCS, related to average milk yield, fat per cent, SNF per cent was taken into consideration for the present study and a correlated study of BCS and the milk yield was studied. The selected animals were divided into four groups based on BCS as 2.5-2.99, 3.0-3.49, 3.5-3.99, 4.0-4.49. The mean BCS values of 2.5-2.99, 3.0-3.49, 3.5-3.99, 4.0-4.49 were 2.62, 3.25, 3.56 and 4.25 respectively. Highest milk yield was recorded in second month of lactation and lowest in first month of lactation with 9.445±0.15 and 6.18±0.08 kg per day, respectively. The buffaloes with BCS 4.0-4.49 yielded higher milk yield when compared to other groups. Highest fat and SNF percent was observed in the animals with BCS 4.0-4.49 when compared with others. The BCS had showed high positive correlation with SNF (0.44) and milk yield (0.41).

Relationships between Body Condition Score (BCS), FAMACHA©-Score and Haematological Parameters in Alpacas (Vicugna pacos), and Llamas (Lama glama) Presented at the Veterinary Clinic

Simple SummaryAlpacas and llamas are increasingly presented at the veterinary clinic in Germany. Owners often notice too late when their animal is emaciated or anaemic. Emaciation can be detected by checking the so-called body condition score (BCS). An indication of anaemia can be provided directly by the FAMACHA©-score (FS), which has been adopted from small ruminants. There is still little information on both scores for alpacas and llamas, so a retrospective evaluation of data from the veterinary clinic was carried out. More than half of the animals admitted to the clinic were too lean and more than one in ten alpacas or one in five llamas showed clinical signs of anaemia. Both scores were compared with the findings from the animals’ blood counts, which showed that poor nutritional status was associated with anaemia and shifts in inflammatory cells. Regular monitoring of BCS and FS is therefore important in alpacas and llamas to detect emaciation and anaemia in time.South American camelids (SAC) are being more and more presented at the veterinary Clinics in Germany. A bad nutritional condition, which can be easily categorized using a body condition score (BCS) of the animals, is often not noticed by the owners. Further anaemia is also often only detected in an advanced stage in SAC. Clinical detection of anaemia can be performed by assessing the FAMACHA©-score (FS), that is adapted from small ruminants. So far, there is only little information available about BCS and FS in SAC. In this study, both clinical scores were assessed in alpacas and llamas presented at the veterinary clinic and compared with the haematological parameters from the animals. The data were extracted retrospectively from the animals’ medical records and compared statistically. More than half of the alpacas (60%) and llamas (70%) had a BCS < 3, while 12% of the alpacas and 21% of the llamas had a FS > 2. A decreased BCS was associated with a decrease in haematocrit, haemoglobin, lymphocytes, and eosinophils, as well as an increase in FS and neutrophils. BCS and FS should be assessed regularly in SAC to detect emaciation and anaemia in time.

Role of body condition score and adiponectin expression in the progression of canine mammary carcinomas.

Obesity has been identified as a risk factor for developing breast cancer in post‐menopausal period in humans and has been suspected to be associated with a worse prognosis also in the bitch. The aims of this study were to investigate the association between body condition score (BCS) and the prognosis of canine mammary carcinomas (CMCs) and the relationships between adiponectin expression and tumour behaviour. Seventy‐three bitches with tubular, tubulopapillary, solid or complex carcinomas were included in the present study. For each dog, evaluation of BCS was conducted using a nine‐point BCS system and the study population was divided into normal weight (4–5/9 points; n = 42), overweight (6–7/9 points; n = 19) and obese (8–9/9 points; n = 12). Type of diet (commercial, homemade or mixed) was recorded. After surgical excision, histological type, tumour size and nodal status were assessed and adiponectin expression was determined and quantified by immunohistochemistry and morphometric analysis. CMC histotype was not correlated with BCS, while a positive correlation between BCS and histological grade (p < .01) was observed. Overweight and obese bitches combined showed a shorter cancer‐specific survival than normal weighted bitches (p < .01). Bitches fed with a homemade diet had a higher BCS than dogs fed with a commercial one, although no relationship was observed between diet and cancer‐specific survival. Thirty‐six CMCs scored positive for adiponectin expression (49%), but no correlation was found between the hormone expression and either CMC characteristics or prognosis. In conclusion, a higher BCS seems to be related with a higher prevalence of more aggressive CMCs and negatively affects the survival time in bitches with these mammary tumours.

Relationship between body condition score loss and mRNA of genes related to fatty acid metabolism and the endocannabinoid system in adipose tissue of periparturient cows

The endocannabinoid system (ECS) controls feed intake and energy balance in nonruminants. Recent studies suggested that dietary management alters the expression of members of the ECS in the liver and endometrium of dairy cows. The aim of this study was to determine the relationship between body condition score (BCS) loss and the mRNA abundance of genes related to fatty acid metabolism and the ECS in the subcutaneous adipose tissue (AT) of dairy cows. The BCS was determined in multiparous (3.2 ± 0.5 lactations) Holstein cows at −21 and 42 days relative to calving (designated as d = 0). Cows were grouped into three categories according to BCS loss between both assessments as follows: (1) lost ≤0.25 unit (n = 8, low BCS loss (LBL)), (2) lost between 0.5 and 0.75 units (n = 8, moderate BCS loss (MBL)) and (3) lost ≥1 unit (n = 8, high BCS loss (HBL)). Concentrations of haptoglobin and non-esterified fatty acids (NEFAs) were determined in plasma. Real-time PCR was used to determine mRNA abundance of key genes related to fatty acid metabolism, inflammation and ECS in AT. Milk yield (kg/day) between week 2 and 6 post-calving was greater in the LBL group (49.4 ± 0.75) compared to MBL (47.9 ± 0.56) and HBL (47.4 ± 0.62) groups (P < 0.05). The overall mean plasma haptoglobin and NEFA concentrations were greater in MBL and HBL groups compared with the LBL group (P < 0.05). The mRNA abundance of TNF-α, Interleukin-6 (IL-6) and IL-1β was greatest at 21 and 42 days post-calving in HBL, intermediate in MBL and lowest in LBL groups, respectively. Cows in the HBL group had the greatest AT gene expression for carnitine palmitoyltransferase 1A, hormone sensitive lipase and adipose triglyceride lipase at 21 and 42 days post-calving (P < 0.05). Overall, mRNA abundance for very long chain acyl-CoA dehydrogenase and peroxisome proliferator-activated receptor gamma, which are related to NEFA oxidation, were greater in MBL and HBL groups compared to the LBL group at 42 days post-calving. However, mRNA abundance of fatty acid amide hydrolase was lower at 21 and 42 days post-calving in HBL cows than in LBL cows (P < 0.05). In summary, results showed a positive association between increased degree of BCS loss, inflammation and activation of the ECS network in AT of dairy cows. Findings suggest that the ECS might play an important role in fatty acid metabolism, development of inflammation and cow’s adaptation to onset of lactation.

The Effects of Non-Genetic Factors on The Birth Weight, Litter Size and Pre-Weaning Survive Ability of Etawah Cross-Breed Goats in The Breeding Village Center in Ampelgading District

A total of 106 late gestation goats (age 4-5 months of pregnancy) records each of Etawah Crosbred goats kept on small farmer over a period of 10 years were assessed to determine the effects of environmental factors on them. Body Condition Score is non-genetic factor and in dairy goats to predicted milk production, fertility, and general health of the animal because BCS is visualisasi from feeding manajement. The objective of this study was to investigated the relationship between Body Condition Score (BCS) of late gestation with litter size and birth weight on etawah crossbred goats. The results showed that the average of litter size and birth weight (kg) were 1.89±0.66 and 3.84±0.73 respectively. The relationship between BCS with litter size were 0.13 (very low) and the relationship between BCS with birth weight were 0.11 (very low). The conclusion of this research is BCS of late gestation had positive correlation on litter size and birth weight, however this was low and birth weight as first indicator of future growth rate.

Association of changes among body condition score during the transition period with NEFA and BHBA concentrations, milk production, fertility, and health of Holstein cows

Our objective was to evaluate the association between body condition score (BCS) change during the transition period with fertility, non-esterified fatty acids (NEFA) and beta-hydroxybutyrate (BHBA) concentrations, milk yield, and health problems of Holstein cows in a retrospective cohort study. Holstein cows (n = 232) were assessed for BCS (5 point scale; 0.25 point increments) and had blood collected at 21 and 7 d before, on the day of, and 7 and 21 d after calving. Blood samples were assayed for NEFA and BHBA concentrations. All cows received a timed artificial insemination (TAI) at 65 ± 3 days in milk (DIM) following a Presynch-Ovsynch protocol with a progesterone implant during the Ovsynch protocol. Cows were grouped based on BCS change after calving as to whether they: 1) lost (L), 2) maintained (M), or 3) gained (G) BCS. Data were analyzed by logistic regression with GLIMMIX and ANOVA with repeated measures using the MIXED procedures of SAS. Both NEFA and BHBA concentrations after calving differed (P < 0.01) for cows that lost, maintained, or gained BCS from 21 d before to 21 d after calving (NEFA: 0.51 ± 0.01; 0.45 ± 0.01; 0.42 ± 0.01 mmol/L; BHBA: 0.73 ± 0.02; 0.70 ± 0.02; 0.68 ± 0.02 mmol/L; respectively; mean ± SEM). By design, BCS change after calving differed (P < 0.01) among groups and was −0.38; 0.00; and 0.35 for cows in groups L, M, and G, respectively. At 21 d before and 21 d after calving, BCS differed (P < 0.01) among groups and was [before (2.97, 2.70, and 2.57) and after (2.54, 2.70, and 2.90)] for cows in groups L, M, and G, respectively. Between evaluated days, higher circulating NEFA and BHBA concentrations were observed 7 d after calving. Change in BCS affected (P < 0.01) pregnancy/AI (P/AI), days to first ovulation, and percentage of cyclic cows at 50 DIM. At 32 d after TAI, P/AI differed (P < 0.01) for cows that lost [18% (11/84)], maintained [33% (26/80)], or gained [47% (32/68)] BCS. Cows that lost BCS during the transition period had more health events (P < 0.01), than cows that gained or maintained BCS. In conclusion, changes in BCS during the transition period affected NEFA and BHBA concentrations, fertility, and occurrence of health problems during the lactation.

Correlation of body condition score, weight, measurements and effect of parity and stage of lactation on milk parameters of Gir cows

Experiment was conducted on 100 Gir cows of different parity and stage of lactation maintained at Ashti Dairy Farm, Ashti taluka Partur, district Jalna of Maharashtra state. The present experiment was carried out to know the effect of parities and stage of lactation on milk parameters &lt;italic&gt;viz&lt;/italic&gt;; WeeklyMilk Yield (WMY), WeeklyFat CorrectedMilk Yield (WFCMY), Fatand Solid Not Fat (SNF) percent and correlation between Body Condition Score (BCS), Body Weight (BW) and body measurements viz; height at wither, height at hook, heart girth and body length with milk parameters. The Least Squares Analysis of Variance has revealed significant effect of parity on the WMY, WFCMY and Fat percentage whereas, significant effect of stages of lactation on the WMY and WFCMY of Gir cows. The positive to negative significant correlation coefficients of body condition score with WMY (0.110); Height at wither with WMY (0.131) and Fat percent (-0.156); Hearth girth with WMY (0.125) and Fat percent (-0.155) and Body length with Fat percent (-0.139) respectively.

Relationship between the pre- and postpartum body condition scores and periparturient indices and fertility in high-yielding dairy cows

Abstract Introduction: The aim of this study was to investigate the relationship between body condition score (BCS) determined on the dry-off day, calving day, and in the first month of lactation, its changes during the dry period and early lactation, and periparturient indices and fertility in high-producing dairy cows. Material and Methods: The experiment was conducted in two herds: A and B, located in Western Poland. The studies were conducted on 116 and 108 Polish Holstein-Friesian dairy cows respectively, with an average milk yield of &gt;10 000 kg/305-day lactation. The experiment included the dry period (-56 d to the calving day), the calving day, and early lactation (from +1 to +56 d). The experimental factor was BCS (0 to 5-point scale). The BCS was performed by one person on day -56, on parturition day (in the first 12 h after calving) and on day 30 of lactation. Results: A decrease in BCS (≥-0.25) in herd A during the dry period accelerated the planned calving period by 7.3 d. In the group of cows with BCS &lt;3.25 on the dry-off day, the lowest artificial insemination index (1.80), the shortest period of insemination services (25 d), and days open (87 d) were recorded. Moreover, cows with BCS &lt; 3.25 at calving had the shortest days open (91 d). BCS &gt;3.50 in the first month of lactation (30 d) resulted in the extension of uterine involution period (56 d). Improvement of BCS during the dry period shortened the anoestrus (60 d) in herd A and the period of insemination service (60 d) in herd B. However, in this group (IM BCS ≥ 0.25) of cows the day of the highest artificial insemination index (2.50) in herd B was analysed. Conclusion: The body condition on the dry-off day and at calving, as well as its deterioration in the first month of lactation, have a considerable effect on fertility indices in dairy cows, thus confirming the advisability of its regular monitoring during routine operations connected with the management of a dairy cattle herd.

Effect of Body Condition Score and Parity on Resumption of Postpartum Ovarian Activity in Montberliard Dairy Cows in Algerian Semi -Arid Area

A study was undertaken to evaluate the relationships between body condition score (BCS), parity and serum hormonal profiles (progesterone (P4) and estradiol -17β (E2)), and resumption of postpartum ovarian cyclicity on (primiparous (n=19) and multiparous (n=59) Montbeliard cows. The BCS was measured at calving, using a 1 to 5 point scale according to the Edmonson (1989) method. Blood samples were collected by jugular venous at 30 d, 40 d, 50 d and 60 d postpartum (10 days of interval). Serum hormonal analysis were determined by chimiluminescent Immuno-Assay (CLIA). Changes in progesterone concentration were exploited to assess the resumption of ovarian cyclicity. The results showed a significant increase in progesterone and estradiol -17β serum levels during postpartum period. The correlation analysis showed that P4concentration in cows was positively correlated with their BCS at 30 d, 40 d, 50 d and 60 d postpartum (r =0.630; r = 0.603; r = 0.622 and r = 0.467 respectively; P<0.01). Additionally, the BCS at calving was positively correlated with estradiol -17β concentration at 30 d (r= 0.628); 40 d (r= 0.612); 50 d (r= 0.444) and 60 d (r=0.294) (P<0.01). Furthermore, BCS at calving was strongly but negatively correlated with CCI (r= 0.704; P<0.01). The results of the current study provide an evidence of a negative correlation between calving conception interval and secretion of P4 and E2.
