Analysis of Differences in Farmer Income Estimation Between Middlemen and Animeter For Bali Cattle in Jaro Subdistrict, Tabalong Regency, South Kalimantan

This study investigates differences in farmer income and body weight estimation for male and female Bali cattle in extensive farming in Jaro Subdistrict, Tabalong Regency, South Kalimantan. A random sampling approach was used, involving farmers from nine villages. Statistical analyses revealed a significant difference (p < 0.05) in the body weights of male Bali cattle measured by an animeter compared to those estimated by middlemen. In contrast, no significant difference (p > 0.05) was observed for female Bali cattle. These differences significantly impacted farmer income for male cattle because the income estimated by the animeter exceeded that estimated by the middlemen (p < 0.05). However, no significant difference (p > 0.05) was observed between the two estimation methods for female cattle. In addition, no significant relationship was observed between the estimates made by the middlemen and those made by the animeter for both sexes of Bali cattle. This study used the Monte Carlo simulation to predict demand for male and female Bali cattle in 2024. On average, farmers were able to supply between two and three male Bali cattle and between three to seven female Bali cattle per month. To ensure a steady income, farmers are advised to supply at least one male or female Bali cattle. Moreover, farmer groups are encouraged to compensate for cattle shortages or surpluses, thereby ensuring a stable supply for middlemen and consumers.

Cholesterol and Blood Profile of Bali Cattle Fed Chromolaena odorata Weed with Rice Straw as Basal Feed

This study aims to determine the effect of the level of C. odorata (CO) silage-based concentrate on the blood profiles of Bali cattle. Three male Bali cattle (initial 2 years old with CV = 19,28%) were randomly assigned to one of three meals: rice straw and concentrates containing C.odorata silage 30% (RCO30) or C.odorata silage 40% (RCO40) or C.odorata silage 50% (RCO50), respectively, using a 3 x 3 Latin Square Design. The was no significant effect between treatments (P> 0.05) on blood cholesterol (195.74-220.49 mg/dL), blood urea (48.41-49.44 mg/dL), total blood plasma (6.08-6.93 g/dL), blood haemoglobin (Hb; 18.18-18.92 g/dL), hematocrit levels (45.56-53.03%), erythrocytes (7.06-8.24 106/l), and leucocytes (8.56-8.84/l). Blood glucose levels, however, differed significantly (P<0.05) between treatment. Feeding Bali cattle with different levels of C.odorata-based concentrate resulted in the same effect on all blood parameters except blood glucose. Therefore, it is recommended that the use of C.odorata in a ration of Bali cattle can be up to 50%.

This study aims to determine the aim of this research, namely to determine the physiological response of male Bali cattle supplemented with complete pelleted feed based on fermented corn cob waste as a source of fiber and Nupro yeast extract supplement. In this study, 4 male Bali cattle were used in the age range of 1 – 1.5 years, with an initial body weight ranging from 101-124 kg with an average of 116.75 kg and a coefficient of variation of 9.16%. This research used an experimental method with a Latin square design consisting of 4 treatments and 4 periods as replications. The treatments in this study were P0: Pellet complete feed (20% fermented corn cob + 80% concentrate + 1% extra Nupro yeast), P1: Pellet complete feed (30% corncob + 70% concentrate + 1% extra Nupro yeast), P2: Pellet complete feed (40% corncob + 60% concentrate + 1% extra Nupro yeast), P3: Pellet complete feed (50% corncob + 50% concentrate + 1% extra Nupro yeast). Data obtained in Analysis Of Variance. The results of this study obtained the average value of body temperature (0C) P0 38.15 ± 0.55, P1 37.94 ± 0.81, P2 38.42 ± 0.39, P3 38.14 ± 0.88, pulse (times/minute) P0 72.08±9.28, P1 71.83±4.21, P2 67.25±13.10, P3 69.33±8.21, Respiratory frequency (times/minute) P0 21,75±1.49, P1 22.08±1.03, P2 24±1.24, P3 22.83±1.68 and water consumption (Liter/head/day) P0 5.68±0.62. P1 5.93 ± 0.82, P2 5.75 ± 0.61, P3 5.75 ± 0.20. The results of statistical analysis showed that the treatment had no significant effect (P>0.05) on body temperature, respiratory frequency, pulse rate and water consumption of male Bali cattle. The conclusion of the research is that complete feed supplementation with pellets containing fermented corn cobs as a fiber source provides and Nupro extra yeast supplement the same physiological response between treatments, so it can be used as a complete feed constituent at a level of 20-50% combined with concentrate feed.

Association of heat-shock protein 70.1 gene with physiological and physical performance of Bali cattle.

Global warming challenges cattle productivity and welfare since it affects heat stress and scarce feed. The heat-shock protein 70 (HSP70) gene is essential in cytoprotection against stressors, protecting cells from dysregulated gene expression and apoptosis. This study aimed to identify significant genetic markers of the HSP70.1 gene that can be leveraged genetically to enhance thermotolerance and production in Bali cattle further. Animals were sampled from three different rearing systems. In this study, 83 healthy adult male Bali cattle without abnormalities were utilized. Single-nucleotide polymorphism (SNP) diversity associated with the physiological and physical traits of Bali cattle was assessed using SNPStat online software. Gene expression for putative SNPs and their genotypic groups was further evaluated. There were 15 polymorphic SNPs (c.-185G>A, c.-69T>G, c.10G>C, c.19A>G, c.45C>T, c.101INS, c.115T>C, c.130T>C, c.136G>T, c.159G>C, c.164G>T, c.234G>A, c.303G>A, c.333C>A, and c.456C>T) identified, of which 12 were associated with the assessed trait. Nine SNPs were associated with physiological traits, while eight were with physical traits. The c.136G>T as a novel, high minor allele frequency, and associative SNP was selected for HSP70 gene expression. Individuals with the TT genotype have a trim physique, susceptible physiology, and high HSP70 mRNA expression. On the other hand, the GG genotype was significantly associated with larger physique, lower physiology, and low HSP70 mRNA expression. The higher expression may indicate that HSP70.1 is involved in mitigating the deleterious effects of stress. As a result, the animal experienced negative energy balance, decreasing body size. Single-nucleotide polymorphism c.136G>T is a candidate biomarker for heat resistance traits in Bali cattle.

PERBANDINGAN AKURASI PENDUGAAN BOBOT BADAN SAPI BALI (Bos sondaicus) MENGGUNAKAN RUMUS LAMBOURNE, SCHROOL DAN DJAGRA (Accuracy comparison of body weight estimation of bali cattle (Bos sondaicus) using lambourne, schrool and djagra formulas)

The predominant method of cattle sale in Indonesia relies on estimation through visual assessment of body characteristics (jogrog). Achieving precise body weight estimates is crucial to enhance accuracy and prevent discrepancies in transactions involving the purchase and sale of beef cattle. This study aimed to establish a formulaic approach for calculating body weight that closely approximates measured values and identify constants in the predictive formula that align with actual measurements. The evaluation included assessing variations in body weight prediction methods using the Lambourne, Schrool, and Djagra formulas, based on heart girth and body length. Formula tests were conducted to identify the estimation formula that best approximated actual body weight. The research, carried out from April to May 2023 at CV. Sentra Sapi Kalimantan, involved 43 male Bali cattle (Bos sondaicus) aged 1.5-2.5 years. Results at CV. Sentra Sapi Kalimantan indicated an average heart girth of 136.89±7.05 cm, body length of 111.22±5.10 cm, and body weight of 192.62±26.62 kg. Data analysis was performed by calculating deviation percentage and linear regression analysis, revealed a substantial deviation of 37.37±13.83% between the Schrool formula and actual weight. In contrast, the Lambourne and Djagra formulas exhibited non-significant deviations of 8.73±6.86% and 8.54±6.29%, respectively. Conclution base on accuracy comparison of body Weight estimation of Bali cattle (Bos sondaicus) using Lambourne, Schrool and Djagra formulas found constanta and effective formula to estimate real cobt weight of Bali cattle: BW = -276.423 + 3.468 HG (cm) – 0.077 BL (cm).

Utilising locally based energy supplements in leucaena and corn stover diets to increase the average daily gain of male Bali cattle and the income of smallholder farmers

Context Supplementing a leucaena-based diet with locally available energy sources is an important strategy to extend the use of leucaena, increase liveweight (LW) gain of Bali cattle and increase profit for the smallholder. Aims This study was conducted to evaluate the effect of various local energy supplements in leucaena-based diets on the LW gain of Bali cattle and income-over-feed costs (IOFC). Methods Forty male Bali cattle were divided into five treatment groups (n = 8) and each was fed one of the following diets: (A) control diet, including leucaena ad libitum, with corn stover at 0.5% DM LW and mineral mix, (B) control + cassava meal at 1.0% DM LW, (C) control + cassava peel at 1.0% DM LW, (D) control + cassava peel and corn grain mix at 1.0% DM LW or (E) control + commercial feed at 1.0% DM LW. The experiment was run for 140 days, which included a 20-day adaptation period. Parameters measured included intake, digestibility, imbibed-water intake, LW gain, rumen and faecal parameters, feed conversion and IOFC. Key results Supplementation of local energy sources in combination with leucaena and corn stover diets increased LW gain of male Bali cattle above that of the control diet (P < 0.05). The bulls receiving the cassava peel and corn mix supplement had the highest LW gain (0.57 ± 0.09 kg/day), which was associated with an increase in digestible organic-matter intake (DOMI). There were no treatment differences (P > 0.05) in the rumen parameters (rumen fluid pH, rumen ammonia-N concentration and volatile fatty acids) and all parameters were optimum for rumen digestion. Conclusions The addition of local energy supplements supplied at 1% of LW improved growth rate and extended the use of a limited amount of leucaena and provided a higher IOFC. Implications Replacing approximately 40% of leucaena with energy sources can have three benefits, including an increase in LW gain, an increased capacity of farmers to feed more cattle per hectare and an increased income per cattle being fattened. This can increase the production scale and subsequent farmer income, provided that the energy sources are available at affordable prices and obtainable.

The eel line was 40% thick line, 15% medium line, 25% thin line, and 20% did not have eel line. The metatarsal color was 87.5% white with a firm border and 12.5% white with an indistinct border. The rump color was 82.5% white with a firm boundary and 17.5% white with an indistinct boundary. The tail feather color was 37.5% black-brown, 32.5% brown, and 30% black. Furthermore, the measurement results obtained for quantitative properties were 113.8 ± 10.0 for body length, with a 8.8% coefficient of variation. Chest circumference were 147.2 ± 11.8, with a 8.0% coefficient of variation. Back height were 112.0 ± 7.9, with a 7.1% coefficient of variation. Hip height were 115.8 ± 8.4, with a 7.2% coefficient of variation. Body weight were 287.6 ± 40.1, with a 14.0% coefficient of variation. The study results show that the male bali cattle characteristics at Dompu Regency are relatively heterogenous, both qualitatively and quantitatively.

Efficacy of concentrates containing tropical weed Chromolaena odorata, methionine hydroxy analog and palm oils in fattening male Bali cattle: A physiological study

Chromolaena odorata is a potential feed source but is low in methionine, which might affect the rumen function. Therefore providing efficient nutrient/s might improve rumen function. The study aimed to assess the efficacy of a concentrate containing Chromolaena odorata meal, hydroxy methionine analog (HMA), and palm oil on blood metabolites of fattened cattle. Sixteen Bali cattle (Bos sondaicus) with an average body weight of 130.5kg ± 32.5 were allotted into four dietary treatments (and four replicates) using a Completely Randomized Block Design with 4 cattle in each Group. The treatments were concentrates with no addition of palm oil and/or HMA as the control diet (Group I) , added with 3 g HMA (CMA) (Group II), added with 0.5% palm oil (Group III) and (CPO) added with a combination of 3 g HMA and 0.5% palm oil (CMO) Group IV). The concentrate was offered to the animals at a rate of 2% liveweight, whilst rice straws were provided ad libitum as the source of fiber. The concentrate contained 18% crude protein and 12 MJ ME/kg DM to target a live weight gain of at least 0.6 kg/day. Blood metabolites measured were total cholesterol levels, plasma glucose, plasma proteins, and plasma urea. Collected data were subjected to analysis of variance with the significance level set at an alpha value of ≤ 0.05. The results showed that providing concentrate-containing. C. odorata with or without HMA and/or palm oil (Group IV) only significantly affected blood plasma proteins, whereas other blood metabolites were unaffected. It might be concluded that there is no benefit of adding palm oil or methionine analog to chromolaena-based concentrate for fattened cattle since it will not affect the concentration of blood metabolites.

The study aims to investigate the influence of supplementation of hydroxy methionine analogues (HMA) and vegetable oils (VO) on testosterone hormone levels and physiological profile of blood plasma of fattening Bali cattle. A randomized block design with four treatments and four tests was used in the study. Sixteen male Bali cattle with a body weight range of 78-183 kg with CV of 25.33% were used. The ration containeds 18% protein and ME = 16 MJ/kg DM with a target weight gain of 0.6 kg/day. The ration is prepared with a protein content of 18% and metabolic energy = 16 MJ / kg BK with a target of weight gain of 0.6 kg / day. Concentrate is given as much as 3% of body weight while rice straw and drinking water are provided ad libitum. The treatment were as follows: RA = concentrate containing C. odorata flour + rice straw ad libitum (control); RB = RA + 3 g HMA; RC = RA + 0.5% VO and RD = RA + 3 g HMA + 0.5% VO. The variables measured were as follows: testosterone hormone, erythrocytes, hemoglobin, leucocytes and hematocrit. The results showed that the supplementation of HMA and VO had no significant effect (P˃0.05) on testosterone hormone levels and physiological profile of blood plasma of the study livestock. It was concluded that the use of AHM and VO had no impact on changes in testosterone hormone concentrations and blood profiles of study cattle

Growth Performance of On-Farm Male Fattening Bali Cattle Fed with Fodder Obtained from Dry Land Farming Diversification in West Timor

This study aims to determine the effect of feeding fodder obtained from diversified dry land farming on daily weight gain, chest girth, shoulder height, and body length of male fattening Bali cattle. This study used a double Latin square design (LSD) with 4 treatments, namely T0 = local feed of farmers in Timor (farmer model). T1 = Diversified farm feed (T1 + mulato grass), T2 = T1 + legume Clitoria tarnatea, T3 = T2 + horticulture by-product using 4 periods as replicates. The livestock observed were eight male Bali cattle aged eight months to one year and weighed 97-121 kg (average 108.5 kg). The results showed that the feeding fodder obtained from the diversified farming had a significant effect (P<0.05) on daily body weight gain but not significant (P>0.05) on the linear body size measurements (chest girth, shoulder height, and body length). Considering the economical and convenient features, T2 feed treatment provided a greater contribution of 21.74% compared to control.

Deterioration of Frozen Semen of Bali Cattle after Cooling at 5°C

Frozen semen is produced through several stages, which deteriorate spermatozoa. This research aimed to evaluate the deterioration degree of frozen semen after 5 °C cooling and freezing of Bali cattle. The samples included 10 male Bali cattle with a body weight of 542-668 kg, from which semen was collected once a week for five weeks. The deterioration of each individual’s sperm was determined by observing two distinct straws. The parameters observed included viability, abnormalities, intact plasma membrane, and intact acrosome cap. Initial observations of the parameters were conducted following the addition of semen to diluent A1 (AD) as much as the volume of fresh semen. The semen in the AD group was not cooled and frozen. The A1 semen was then divided into two, namely, those with cooling at 5 °C for 4 hours (PT1) and at 5°C for 22 hours (PT2). The results showed that individual variations in Bali cattle caused significant differences in viability and intact plasma membrane of AD and PT1 groups, while PT2 did not differ in viability and intact plasma membrane spermatozoa. Abnormalities were significantly different between AD and PT2 groups, however PT1 did not differ in abnormalities spermatozoa. Intact acrosomal cap was significantly different in the AD, PT1, and PT2 groups. In conclusion, individual variations, including viability, abnormalities, intact plasma membrane, and acrosome cap of spermatozoa, were better at 4 hours compared to cooling at 5°C for 22 hours. A Cooling time of 4 hours at 5°C can be recommended for frozen semen processing.

The purpose of this study was to determine the blood glucose and urea levels of male Bali cattle fattened with complete feed containing fish meal as a protein source. This research method uses a completely randomized design (CRD) with 3 treatments and 5 replications so that there are 15 experimental units with treatment given T1; natural grass 30% + milled corn 42% + rice bran 13% + pollard bran 11% + fish meal 4%, T2: natural grass 42% + milled corn 42% + rice bran 9% + pollard bran 11% + fish meal 8 %, T3: natural grass 30% + milled corn 42% + rice bran 5% + pollard bran 11% + fish meal 12%. The variables observed in this study were blood glucose and blood urea levels of male Bali cattle with a time of 0 hours before feeding, 2 hours, 4 hours, and 6 hours after feeding. The data obtained were tabulated and then analyzed by Analysis of Variance (ANOVA) according to a completely randomized design procedure (CRD) using SPSS version 19.0. The results of this study showed that the use of complete feed containing fish meal as a protein source was not significantly different. Blood glucose levels (mg/dL) for each treatment were T1: 73.23±3.50, T2: 76.24±6.21, T3: 71.94±2.54; Blood urea levels (mg/dL) of male Bali cattle for each treatment were T1: 40.23±3.51, T2: 40.95±2.04, T3: 39.67±1.83. It was concluded that giving a complete feed containing fish meal as a protein source gave the same effect for all treatments and resulted in blood glucose and urea levels of fattened male Bali cattle in the normal range.
