Effect of Dietary Supplementation of Rumen Undegradable Protein on Productive Performance of Early Lactating Buffaloes

An experiment was conducted to study the effect of dietary supplementation of rumen un-degradable protein on productive performance of early lactating buffaloes for the duration of 90 days from February 5, 2014, to May 5, 2014. A total of twenty one lactating Murrah buffaloes in their early to mid-lactation were randomly selected and divided into three groups. Experimental diets were formulated into three- low (30.56% of dietary Crude Protein), medium (43.54% of dietary crude protein) and high (50.04% of dietary CP), iso-nitrogenous (16% CP) and iso-caloric (72% total digestible nutrients) rumen un-digestible protein (RUP) levels. A significant difference (p<0.05) in body weight gain of buffaloes was recorded in animals of high RUP group in comparison to medium and low RUP groups. Milk yield in the medium RUP group (43.54%) was significantly higher than the high and the low RUP group (p<0.05). The mean serum total protein, blood urea nitrogen concentrations were significantly lower in both the high and the medium RUP groups than in the low RUP group (p<0.05). However, blood glucose level was significantly higher in high RUP group than in low and medium RUP group (p<0.05) whereas milk fat, solid not fat, lactose, protein and electrical conductivity showed no significant differences among the three treatment groups (p>0.05). Hence, it can be concluded that the diet containing a medium level of dietary CP as RUP improved the productive performance of early lactating buffaloes. Thus, diet containing the medium level of dietary CP as RUP should be given to improve the productive performance of early lactating buffaloes under the climatic settings of Nepal.

Assessment of liver function status of chickens (Gallus gallus domestica) exposed to factory sites in Nnewi, Anambra State, South Eastern Nigeria

Objective: Nnewi is a growing industrial town in Nigeria and the industries are sited very close to human habitation. Exposure to industrial effluents come with deleterious consequences. The purpose of this study was to investigate the liver function status of chickens exposed to these factory sites in Nnewi Nigeria. Materials and Methods: A total of twenty-nine (29) chicks were allowed to feed from the surrounding homeland of the factory until they aged between four (4) and five (5) months as adult birds (chickens) for the study. The chickens were sacrificed to obtain the blood for analyses. Five (5) ml of blood sample was collected from the heart into plain containers and the serum obtained was used for the estimation of biochemical parameters. Total protein (TP), albumin (ALB), total bilirubin (TB), direct bilirubin (DB), aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP) were assayed using standard laboratory procedures. The data obtained was subjected to statistical analysis using Students t-test using Statistical Package for Social Sciences (SPSS) (version 16) software. Statistical significance was tested at p Results: The mean serum TP, ALB, TB and DB levels as well as ALP activity in chickens reared around factory sites were not significantly different when compared with the control chickens (p>0.05), however, the mean serum activities of AST and ALT were significantly elevated in the factory exposed chickens than those of the control chicken (p Conclusion: This study found a possible compromise between the liver enzymes and the factory environment which could result in poor growth of the chickens. It is recommended that factories be sited away from the reach of the chickens.

Bovine respiratory disease (BRD) cause-specific and overall mortality in preweaned calves on California dairies: The BRD 10K study

Mortality in preweaned dairy calves is a significant source of economic loss for dairy producers. In particular, bovine respiratory disease (BRD) is a leading cause of death in preweaned dairy calves. The objectives of this study were to investigate management practices and their effects on mortality, both that specifically attributed to BRD and overall mortality due to all causes, in preweaned dairy calves. Rates of failure of passive transfer of immunity (FPT) are also reported. The study consisted of a convenience sample of 5 dairies across California, selected based on management practices, calf records, location, and size. Trained study personnel performed comprehensive calf management surveys on every dairy at least once every season. Calves were enrolled in the study at birth and followed until weaning. Mixed-effect logistic regression models were specified for the outcomes all-cause mortality (any death before weaning) and mortality attributed to BRD. The 2 final models included a total of 11,470 calves that were born on the study dairies and followed until weaning. The study cohort's overall crude mortality was 2.8%, with crude mortality of individual dairies ranging from 1.7 to 7.2%. The proportion of mortality attributed to BRD was 19.3%, with a range of 0 to 27.1% on the study dairies. Increasing the frequency of changing maternity pen bedding was associated with a decreased risk of mortality due to BRD. Calves diagnosed with BRD in the spring had an increased risk of mortality compared with calves born in the summer; mortality in calves with fall and winter BRD diagnoses did not different significantly from that in summer. Season of mortality was not significant in either model. Feeding ≥5.7 L of milk per day per calf (vs. ≤3.7 L/d) decreased the risk of mortality in calves over 21 d of age. Twins had a 68% increased risk of all-cause mortality compared with calves born as singletons. Both mortality models showed an association between administration of a modified live vaccine in dams (targeting BRD pathogens) and a decreased risk of mortality in calves. Using a serum total protein cut-off of 5.2 g/dL, 16.8% of calves had FPT, with a mean serum total protein concentration of 5.94 ± 0.06 g/dL across all calves sampled.

Protective Effect of Cordia Myxa Extract on Changes in Body Weight, Serum Proteins, Albumin and Liver Histology of Adult Male Rats Induced by Cadmium Chloride Toxicity

Background: The present study investigated the protective effect of C. myxa extract on the liver biochemical and histologic changes induced by cadmium chloride (CdCl2) in adult male rats. Methods: We used 48 adults male Wistar rats, divided into 6 groups of 8. Control group received water and normal food. Sham group 1 received 2 mg/kg of CdCl2 for 35 days intraperitoneally. In Addition, Sham Group 2 received 125 mg/kg extract of C. myxa fruit for 35 days by gavage method. The experimental groups 1, 2 and 3 received 125, 250 and 500 mg/kg of C. myxa extract for 21 days through gavage, followed by 2 mg/kg of CdCl2 given intraperitoneally for 14 days. After the experimentation period, blood samples were taken and the serum total protein and albumin concentrations measured. Also, liver tissue sections were prepared, stained and examined by light microscopy to evaluate the histologic changes. Results: The mean body weight, serum total protein, albumin in sham group 1 showed a significant decrease in comparison with those in the controls and Sham Group 2. The mean body weight and serum total protein in Experimental Groups 2 and 3 showed a significant increase compared to those in Sham Group 1. The mean serum albumin in Experimental Group 3 showed a significant increase compared to that in Sham Group 1 (P <0.05). Conclusion: The extract of C. myxa fruit demonstrated protective effects on changes in body weight, serum biochemical factors and liver histology induced by the adverse effect of CdCl2 in adult male rats.

Evaluation of combination of antibiotic with multienzyme preparation on bovine mastitis

The study evaluated the efficacy of multienzyme therapy as an adjunct or alternative to antibiotic therapy in mastitic cows. Twenty one cows affected with clinical mastitis were selected and divided into three treatment groups: Group 1 (n=7) animals were treated with enrofloxacin @ 10 mg/kg b.w, I/M for 5 days. Group 2 (n=7) cows received an intramammary infusion consisting of a mixture of three enzymes viz. chymotrypsin (8 mg), trypsin (8 mg) and papain (4 mg) dissolved in 5 ml NS, at 24 hr. interval for 7 days. Group 3 (n=7) cows received a combination of both parental antibiotic (Enrocin) and intramammary infusion of multienzymes for 7 days at 24 hours interval. Milk samples were collected prior to the treatment (day 1) and on days 4, 7 and 14 post treatment and blood samples on day 1, 7 and 14. There was significant (P<0.05) decrease in the mean serum total protein (TP) and globulin levels in all the treatment groups post treatment as compared to the pretreatment levels while as the mean serum albumin levels and the A: G ratio showed significant (P<0.05) increase post treatment. There was a significant (P<0.05) decrease in the mean total sialic acid (TSA) levels on days 7 and 14 after treatment as compared to the pre-treatment levels in all the three groups. Mean somatic cell count (SCC), standard plate count (SPC) and electrical conductivity (EC) values decreased significantly on days 4, 7 and 14 as compared to that of the day 1. It was concluded that therapeutic intervention with parenteral enrofloxacin and intramammary infusion of proteolytic enzymes improved the udder health of dairy cows affected with clinicalmastitis.

Serum Calcium and Magnesium Levels in Normal Ghanaian Pregnant Women: A Comparative Cross-Sectional Study.

BACKGROUND:Pregnancy is described as a normal physiologic state associated with various biochemical changes. Magnesium and calcium are essential macronutrients required for foetal growth. Complications associated with their deficiency during normal pregnancy include; low neonatal birth weight, pre-eclampsia, eclampsia and preterm labour. Changes in serum levels of magnesium and calcium in normal pregnancy have not been extensively studied among Ghanaian women.AIM:To determine the variation in serum magnesium and calcium levels with gestational age in normal pregnancy in Ghanaian women.METHODS:A hospital-based comparative cross-sectional study was conducted among 32 normal non-pregnant women (Group A) and 100 normal pregnant women (Group B) attending the clinic at the Korle-Bu Teaching hospital. The group B pregnant women were further divided into Group B1 (n = 33), Group B2 (n = 37) and Group B3 (n = 30) based on their pregnancy gestation as first, second and third trimester respectively. Blood samples were obtained from the antecubital vein of subjects and total serum calcium, magnesium, protein and albumin were estimated. Data obtained were analysed using SPSS for windows version 20. Analysis of variance (ANOVA) was employed to determine the statistical differences between the groups. A p-value of ≤ 0.05 was considered significant.RESULTS:Mean serum total calcium and magnesium in first, second and third trimester normal pregnant women were 2.14 ± 0.16, 2.13 ± 0.44, 2.13 ± 0.35 mmol/L and 0.77 ± 0.11, 0.77 ± 0.16 and 0.76 ± 0.14 mmol/L respectively. Mean serum total calcium and magnesium levels in non-pregnant women were 2.20 ± 0.16 and 0.80 ± 0.10 mmol/L respectively. There was a statistically non-significant difference in serum total calcium and magnesium between non-pregnant and normal pregnant women, with p-values of 0.779 and 0.566 respectively. Mean total serum protein and albumin in first, second and third-trimester normal pregnant women were 68.42 ± 10.37, 70.46 ± 6.84, 66.70 ± 7.83 g/L and 39.92 ± 3.22, 40.75 ± 8.06, 38.26 ± 3.02 g/L respectively. Mean total serum protein and albumin in non-pregnant women were 73.13 ± 7.02 and 42.94 ± 3.03 g/L respectively. Mean total serum protein and albumin levels were lower in pregnant women as compared to non-pregnant women with the difference being significant in the third trimester (p-values of 0.012 and 0.002).CONCLUSION:Total serum calcium and magnesium levels in normal pregnancy were non-significantly lower compared to non-pregnant women in Ghana. There was a reduction in total serum protein, and albumin levels during pregnancy with a significant reduction noticed during the third trimester compared to the non-pregnant state.

Observations on the Activities of Certain Serum Enzymes and Levels of Some Biochemical Parameters in Spent Horses with Liver Damage

Clinical biochemistry tests are one of the tests designed to assess the functional status of the liver in domestic animals and man. This study evaluated the activities of some serum enzymes and the level of some biochemical parameters in horses with acute and chronic liver damage. This study was carried out in Nigerian horses presented for sale at the Obollo Afor horse depot, Udenu Local Government Area, Enugu State Nigeria. A total of 100 adult Nigerian horses of either sex were studied once a week for a period of 24 weeks. Serum biochemistry parameters indicated for the assessment of liver function were evaluated following standard procedures. These parameters include: Alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), total proteins, albumin, globulin, total cholesterol, total bilirubin and urea. Based on the outcome of the serum biochemistry evaluation, the horses were assigned into 3 groups namely: apparently healthy horses (Group 1), horses with biochemical markers of acute liver damage (Group 2) and horses with biochemical markers of chronic liver damage (Group 3). The mean serum ALT, AST, ALP and total bilirubin values of group 2 horses were significantly (p &lt; 0.05) higher than those of groups 1 and 3 horses. The mean serum albumin value of group 2 horses was significantly (p &lt; 0.05) lower than that of groups 1 and 3 horses. There was no significant (p &gt; 0.05) difference in the mean serum urea value of group 2 and 3. A significantly (p &lt; 0.05) lower serum creatinine value was observed in group 2 horses. There were no significant (p &gt; 0.05) differences in the mean serum total protein, globulin and cholesterol values across the groups. In the spent horses, acute liver damage was characterized by increased serum ALT, AST and ALP activities, and decrease in creatinine level, hyperbilirubinemia, slight hypoalbuminemia, normal total protein, globulin and cholesterol levels while chronic liver damage was characterized by decreased serum ALT activity, normal serum AST and ALP activities, decreased serum urea level, normal total protein, albumin, globulin, total bilirubin and cholesterol levels.

Dietary encapsulated probiotic effect on broiler serum biochemical parameters.

Aim:The study aimed to evaluate the effect of encapsulated probiotic bacteria (Lactobacillus lactis and Bifidobacterium bifidum) on broiler serum biochemical parameters.Materials and Methods:Encapsulation protects the probiotics and increases their livability on exposure to unfavorable processing and storage temperatures and gastrointestinal pH. Hence, an in vitro study was undertaken to encapsulate the probiotic bacteria L. lactis and B. bifidum with sodium alginate and chitosan and evaluate the encapsulation efficiency. This experiment was conducted with 288-day-old broiler chicken; they were distributed randomly into eight treatments and six replicates in each treatment (six birds in each replicate) and given with standard feed.Results:Supplementation of the encapsulated bacteria either alone or in combination (T4, T6, and T8) significantly (p<0.05) increased mean total serum protein, albumin, and globulin as compared to the birds that were not supplemented with any probiotic (T1 and T2) or supplemented with non-encapsulated bacteria (T3, T5, and T7). Supplementation of the encapsulated bacteria either alone or in combination (T4, T6, and T8) significantly (p<0.05) lowered mean total serum cholesterol, serum low-density lipoprotein (LDL) cholesterol, and serum triglycerides, as compared to the birds that were not supplemented with any probiotic (T1 and T2) or supplemented with non-encapsulated bacteria (T3, T5, and T7).Conclusion:It may be concluded that supplementation of the encapsulated probiotic bacteria either alone or in combination significantly increased total serum protein, albumin, and globulin and significantly lowered mean total serum cholesterol, serum LDL cholesterol, and serum triglycerides as compared to the birds that were not supplemented with any probiotic or supplemented with non-encapsulated bacteria.

Effects of protein supplementation on resistance and resilience of lambs naturally infected with gastrointestinal parasites

In this study, the objective was to evaluate the efficacy of protein supplementation on gastrointestinal nematode control in lambs naturally infected. Sixty weaned Ile de France and Texel crossbred lambs, with 60 days of age, were divided into three groups (n=20) according to the level of protein in the concentrate: low protein (LP; 8.5%), moderate protein (MP; 15%), and high protein (HP; 25%). The daily amount of concentrate offered was based on 3% of live weight, which was continued throughout the experiment of 98 days. Evaluations were conducted biweekly from days 0 (D0) to 98 (D98). There were no significant differences (p &gt; 0.05) in the average weight among the LP, MP and HP groups, which was 22.0, 21.4, and 21.1 kg, respectively, on D0 and 46.4, 48.3, and 48.2 kg, respectively, on D98. The daily weight gain was not significantly different among the groups (LP, 250 g; MP and HP, 276 g; p &gt; 0.05). The average egg count per gram of feces (epg) of the LP group on D98 (6,765; an increase of 5,690 epg from D0) was higher than that of the MP and HP groups (1,617.5, p &lt; 0.05 and 3,435, p &gt; 0.05, respectively), which remained constant throughout the study. The hematocrit values decreased (p &lt; 0.05) from D0 to D98 only in the LP group. Only in the HP group (p &lt; 0.05), the mean serum total protein concentration increased from D0 (5.3 g dL-1) to D98 (5.8 g dL-1). The average albumin level on D98 (2.10 g dL-1) was lower than that on D0 (2.52 g dL-1) in the LP group (p &lt; 0.05). During the study, 10 lambs overall were treated with anthelmintic because the epg values exceeded 10,000; six treated lambs were from the LP group, 3 from the HP group, and only 1 from the MP group. These results indicate that supplementation of diet with 15% protein increases the resistance and resilience of lambs to gastrointestinal parasites.

Prevalence of failure of passive transfer of immunoglobulins in Holstein calves in Northern Greece and association with management practices

Objectives of the present study were to estimate prevalence of failure of passive transfer of immunoglobulins in dairy calves in Northern Greece and to investigate factors potentially associated with it. Four hundred and thirty seven clinically healthy calves in 30 farms were included in the study. Age of calves was 18 h to 7 d. Animals were blood sampled and serum total protein concentrations were measured by a refractometer. Two thresholds of total protein concentration were used: 5.2 or 5.5 g dL 1. At calf level, an animal was considered to have failure of passive transfer of immunoblobulins when total protein concentrations were lower than the above thresholds. At herd level, a herd was considered to have failure of passive transfer of immunoglobulins when &gt;20% of sampled calves had total protein concentration was &lt;5.2 or &lt;5.5 g dL-1.Moreover, data on health management on the farm were collected in a purpose-built questionnaire. At 5.2 g dL-1, 20% of the calves and 40% of the herds were considered to have failure of passive transfer of immunoglobulins; when the 5.5 g dL-1 threshold was used, respective prevalences were 26% and 53%. At herd level, mean blood serum total protein concentration tended to be positively affected by a short interval between birth and first colostrum meal, by maintenance of a stock of frozen colostrum and by establishment of a close-up group of dry cows. At calf level, the same factors had a statistically significant positive effect on blood serum total protein concentration. Moreover, quantity of colostrum received by calves and colostrum condition were also positively related with blood serum total protein concentration. In conclusion, failure of passive transfer of immunoglobulins is a common problem in Holstein calves in Northern Greece. Increased prevalence of the problem implies that increased efforts and management practices need to be applied to ensure the adequate transferof maternal immunoglobulins to newborn calves. Also, it becomes obvious from all the above findings that many farmersare not well informed for management practices that have to implement to ensure adequate amounts of immunoglobulins tonewborn calves. Hence, dissemination of knowledge concerning best management practices for achieving adequate passiveimmunity is considered to be of significant importance.

Protective Effect of Terminalia Chebula Extract on Serum Total Protein against

Terminalia Chebula extract is used for regeneration of hepatic cells and protection of liver against damage due to its active component. This study aims to observe the protective effect of Terminalia Chebula against Paracetamol induced change of serum total protein level in Wister Albino rats. The study was carried out in the Department of Physiology, Dhaka Medical College (DMC) during January 2013 to December 2013. A total number of 44 rats, age ranging from 90 to 120 days, weight between 150 to 200 gm (initial body weight) were selected for the study. After acclimatization for 14 days, they were divided into control groups and experimental groups. Before sacrifice, final body weights of all the rats were measured. then all the rats were sacrificed on 22nd day and then blood samples were collected. For assessment of liver function, serum total protein level was done by using standard laboratory kits. The mean serum total protein level was significantly (p&lt;0.001) lower in paracetamol treated control group in comparison to those of baseline control group. Serum total protein level of all experimental groups were significantly (P&lt;0.001) higher than Paracetamol treated control group. From the results of this study, it may be concluded that Terminalia Chebula may have some protective effect against Paracetamol induced liver damage in rats.Bangladesh Med J. 2017 Jan; 46 (1): 11-14

Effects of Vitamin E Supplementation in Male Rats with Crude Oil-Induced Reproductive Toxicity

Crude oil intoxication is a major threat among people and animals living around the crude oil producing regions of the world, hence the search for ameliorating agents. Forty-four male Wistar rats assigned into three groups were used to investigate the effects of vitamin E supplementation on crude oil-induced reprotoxicity (reproductive toxicity) in male rats. Group A represented the unexposed control, whereas groups B and C were exposed orally to 0.15 and 0.3 ml of crude oil respectively every other day for 56 days. Both the low dose and high dose oral administration of crude oil caused a significant reduction in the serum testosterone level (STL) and cauda epididymal sperm reserve (CESR) of the exposed rats when compared to the control. Crude oil withdrawal and vitamin E supplementation significantly improved the cauda epididymal sperm reserve (CESR) in all the subgroups. The serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities of the control and low dose group were significantly lower than those of the high dose group. The high dose crude oil administration significantly decreased the mean serum total protein (STP) and sodium ions (Na+) concentration. The mean serum total cholesterol (STC) value of the low dose group was significantly higher than those of the control and high dose group. However, crude oil withdrawal and vitamin E supplementation did not significantly alter the mean serum total protein (STP) and mean serum total cholesterol (STC) values in all the subgroups. Vitamin E supplementation following low dose crude oil withdrawal enhanced the mean serum Chloride ions (Cl-)concentration. The present findings revealed that Nigerian Qua Iboe Brent crude oil induced serious reprotoxic effects in male rats which vitamin E administration within 28 days did not completely reverse.

Biochemical abnormalities and Vitamin D levels in sputum positive pulmonary tuberculosis

Background: Tuberculosis has been associated with various biochemical abnormalities including low hyponatremia, serum albumin, hypocalcaemia, low vitamin D levels. Methods: 50 patients aged ? 18years of age with of sputum positive pulmonary tuberculosis were included in the study. Renal function, liver function, electrolytes and Vitamin D levels were measured at 0, 2 and 6 months of anti-tuberculosis treatment. The qualitative variables were analysed by chi-square tests. The quantitative variables were analysed by using paired t test. Five percent probability level was considered as statistically significant i.e., p<0.05. Results: The mean age was 38.5 years with a male to female ratio of 1.08:1. Hyponatremia was present in 24% of the patients. The mean total serum protein value were 6.720.89,7.420.74 and 8.150.68 g/dl and serum albumin of 2.970.50, 3.370.39 and 3.750.37 g/dl respectively at 0, 2 and 6 months. The mean serum calcium values observed were 8.20.63, 8.820.68 and 9.450.63 mg/dl at 0, 2 and 6 months respectively. The mean values for vitamin D at 0, 2 and 6 months were 9.146.94, 15.336.42 and 23.176.86 ng/ml respectively. 92% of the patients had low serum levels of vitamin D and 66% of the patients had serum vitamin D levels less than 10 ng/ml at presentation. Conclusion: Various biochemical abnormalities including hyponatraemia, low serum albumin and protein levels and low serum calcium levels are seen in pulmonary tuberculosis. Vitamin D levels are significantly lower in patients with TB and there is a significant improvement in the vitamin D levels with treatment of TB.

In vitro and in vivo action of Piptadenia viridiflora (Kunth) Benth against Haemonchus contortus in sheep

Anthelminthic resistant populations of Haemonchus contortus are a major problem in sheep rearing, but plant extracts may offer viable alternative treatments. In our preliminary studies, Piptadenia viridiflora was frequently selected by sheep grazing in the Cerrado. The present research evaluated its in vitro and in vivo anthelmintic activity. The HPLC chromatograms of P. viridiflora aqueous extract (AE) and ethanolic extract (EE) showed the presence of flavonoids. The total condensed tannin (proanthocyanidin) was 0.2 and 1.01% in AE and EE, respectively. In an egg hatching inhibition (EHI) test, the LC90 of AE was 2.4mg/mL, and, of EE, was 2.1mg/mL. After tannin extraction, higher EHI and lower LC90 were observed. In a larval development inhibition test, the LC90 of AE was 13.66mg/g of fecal culture. The highest dose of AE administered to mice (203.0mg/kg bw) was well tolerated, suggesting low toxicity. In vivo, AE was orally administered to lambs at 283mg/kg bw, and, at weeks one, two, and three post-treatment, the mean fecal egg count (FEC) was significantly lower than in untreated lambs (P<0.05). Blood parameters were normal and similar in untreated and treated sheep. For all lamb groups, the mean total serum protein was significantly higher at week two post-treatment than at other evaluated periods (P<0.05). Piptadenia viridiflora extracts had low condensed tannin content and exhibited high anthelminthic efficacy in vitro and significantly reduced FEC. Tannins were not shown to be the principal components affecting EHI, hence it is necessary to isolate and characterize the principal active P. viridiflora compounds, and to assess their possible synergism.

Assessment of Renal Function among HIV-Infected Patients on Combination Antiretroviral Therapy at Tikur Anbessa Specialized Hospital, Addis Ababa, Ethiopia

Background: Acquired immunodeficiency syndrome (AIDS) is a spectrum of disease states characterized by progressive immunosuppression. Sub-Saharan Africa is heavily affected by human immunodeficiency virus (HIV) and AIDS than any other region of the world. Renal complications are important component of advanced HIV disease, and these complications significantly contribute to morbidity and mortality in HIV/AIDS patients. Aim of the Study: To assess renal function abnormalities in HIV infected patients and compare with treatment-naive and HIV-negative control groups. Methods: A retrospective cross sectional study of comparative nature was designed and samples and biochemical data were collected from July 1/2012 to February 1/2013 in patients attending the ART clinic at Tikur Anbessa Specialized Hospital, Addis Ababa, Ethiopia. Renal functions of 180 participants were assessed. The data obtained were analyzed using SPSS version 16.0. Result: A total of 180 participants grouped as HIV-negative controls (n = 60), HIV+ treatment-naive (n = 60) and HIV+ on HAART were recruited to participate in this study. Out of 180 participants included in the study, 59 (32.78%) were males and the remaining 121 (67.22%) were females. Mean serum total protein was higher in patients on HAART groups (5.78 ± 1.39) than treatment-naive (4.76 ± 2.19). There was significant reduction (p 2) is higher in treatment-naive participants than those on HAART and HIV-negative control groups.

Serum metabolic and minerals profile in norgestomet primed postpartum anestrous surti buffaloes.

Aim:The study was undertaken to find out the serum metabolic and minerals profile in postpartum anestrous surti buffaloes treated with norgestomet ear implants alone and in combination with pregnant mare serum gonadotropin (PMSG).Materials and Methods:The study was conducted on 18 postpartum anestrous Surti buffaloes divided into three groups of six animals each at random to conduct the experiment. The buffaloes in Group-I and Group-II were implanted with Crestar ear implant for 9 days together with 2 ml injection of Crestar solution given i/m on the day of the implant insertion. In Group-II, additionally 500 IU PMSG was given i/m on the day of implant removal, whereas the buffaloes in Group-III served as anestrous control group and received 5 ml Normal Saline i/m on day 0 and 9 as a placebo treatment.Results:The overall serum total protein values did not differ significantly (p > 0.05) between time (days) intervals in any of the groups. The mean serum total cholesterol levels at 10th day and on the day of estrus were found significantly lower (p < 0.05) in the control group as compared to treatment Groups I and II. However, there was no significant difference (p > 0.05) at 10th day and on the day of estrus between treatment groups (T1 and T2). The overall mean serum cobalt, zinc, iron, and manganese values did not differ significantly (p > 0.05) between different time intervals among any of the groups, except copper which was significantly lower (p < 0.05) at 10th day in control group as compared to treatment groups.Conclusion:Microelements cannot be synthesized in the body. Hence, it is concluded that the mineral mixture should be supplied daily in the animals ration to suffice the requirement of the trace elements. The mean serum metabolic and micro-minerals profiles in treatment and control groups revealed that overall mean serum total protein, cholesterol, copper, and zinc levels were apparently higher in treatment groups whereas, mean serum cobalt, iron, and manganese concentration had no consistent trend between treatment and control groups of Surti buffaloes.

Evaluation of a Brix refractometer to estimate serum immunoglobulin G concentration in neonatal dairy calves

The objective of this study was to evaluate the utility of a digital Brix refractometer for the assessment of success of passive transfer of maternal immunoglobulin compared with the measurement of serum total protein (STP) by refractometry. Blood samples (n=400) were collected from calves at 3 to 6d of age. Serum IgG concentration was determined by radial immunodiffusion (RID), and STP and percentage Brix (%Brix) were determined using a digital refractometer. The mean IgG concentration was 24.1g/L [standard deviation (SD) ± 10.0] with a range from 2.1 to 59.1g/L. The mean STP concentration was 6.0g/dL (SD ± 0.8) with a range from 4.4 to 8.8g/dL. The mean %Brix concentration was 9.2% (SD ± 0.9) with a range of 7.3 to 12.4%. Brix percentage was highly correlated with IgG (r=0.93). Test characteristics were calculated to assess failure of passive transfer (FPT; serum IgG <10g/L). The sensitivity and specificity of STP at 5.5g/dL were 76.3 and 94.4%, respectively. A receiver operating characteristic curve was created to plot the true positive rate against the false positive rate for consecutive %Brix values. The optimal combination of sensitivity (88.9%) and specificity (88.9%) was at 8.4% Brix. Serum total protein was also positively correlated with %Brix (r=1.00) and IgG (r=0.93). Dairy producers can successfully monitor their colostrum management and the overall success of passive transfer using a digital Brix refractometer to estimate IgG concentration of colostrum and calf serum.

Evaluation of health status of horses immunized with snake venom and montanide adjuvants, IMS 3012 (nanoparticle), ISA 206 and ISA 35 (emulsion based) during polyvalent snake antivenom production: Hematological and biochemical assessment

Several biochemical and hematological changes in horses are observed during production of snake antivenom. Although conventional adjuvants like Freund's (Complete and Incomplete) are good immunopotentiators, they produce considerable local reactions in animals. Variety of commercial adjuvants, like montanide adjuvants, having high immunopotentiation and showing lesser side effects are available. The prime objective during antivenom production is to strike a balance between safety of immunized horses and efficacy of the product. In our earlier work, efficacy of montanide group of adjuvants in antivenom production has already been established. The aim of the present work was to assess the safety parameters in horses, viz.: biochemical and hematological, during production of snake antivenom. In the present study, 33 new horses were randomly divided into four groups and hyperimmunized using mixture of snake venoms, viz.: Cobra venom, Russell's viper venom, Krait venom and Echis venom along with montanide adjuvants, IMS 3012, ISA 206, ISA 35 and Incomplete Freund's adjuvant as a control adjuvant; through subcutaneous route at intervals of two weeks. During the immunization period, biochemical and hematological parameters were monitored at 0th, 14th, 21st, 30th and 42nd weeks. The mean hemoglobin values dropped slightly during initial immunization but subsequently regained to normal levels. The mean serum total protein values and globulin levels showed an increment in all the four groups, compared to day zero, vice-versa a slight drop was observed in albumin levels. No significant changes were observed in serum creatinine, bilirubin, alkaline phosphatase and blood urea nitrogen values. Finally, we conclude that montanide adjuvants could be a safer alternative to the conventional adjuvants for primary phase of immunization in antivenom production.

Efficacy of feeding a lacteal-derived colostrum replacer or pooled maternal colostrum with a low IgG concentration for prevention of failure of passive transfer in dairy calves

To compare the efficacy of a lacteal-derived colostrum replacer (LDCR) for the prevention of failure of passive transfer of immunity (FPT) in calves with that of pooled maternal colostrum (MC). Randomized field trial. 568 heifer calves from 1 California dairy. Calves were randomly allocated to 1 of 2 treatment groups and fed 2 doses (200 g of IgG) of an LDCR or 3.8 L of pooled MC. From each calf, blood samples were collected before and approximately 24 hours after treatment. Serum IgG and total protein (TP) concentrations were quantified with standard methods, and the apparent efficiency of IgG absorption was calculated. At 24 hours after treatment, mean serum TP and IgG concentrations were significantly lower for calves fed pooled MC (TP, 4.77 g/dL; IgG, 7.50 g/L), compared with those for calves fed the LDCR (TP, 5.50 g/dL; IgG, 15.15 g/L). Calves fed the LDCR were 95% less likely to develop FPT (OR, 0.05; 95% confidence interval, 0.03 to 0.08) than were calves fed pooled MC. However, the mean IgG concentration in the pooled MC fed during the study (21.1 g/L) was substantially lower than that (64.3 g/L) determined for representative samples of pooled MC from other southwestern US dairies during a national survey. Results indicated that, on this particular dairy, calves fed an LDCR were at less risk of developing FPT than were calves fed pooled MC. The LDCR evaluated was a viable alternative for the prevention of FPT in calves.

Serum Copper and Plasma Protein Status in Normal Pregnancy

Background: Gradual alteration of serum copper and some plasma protein levels may occur with advancement of pregnancy, which is associated with increased maternal and infant morbidity and mortality. Objective: To observe serum copper and plasma protein levels in normal pregnant women of different trimesters in order to find out their nutritional status. Methods: This cross sectional study was carried out in the Department of Physiology, Sir Salimullah Medical College (SSMC), Dhaka, between 1st January 2010 and December 2010. Ninety normal pregnant women of different trimesters with age 20-30 years were included in the study group. They were selected from Out Patient Department of Obstetrics and Gynaecology, SSMC. Age matched 30 non-pregnant women were taken as control. Serum copper level was measured by Spectrophotometric method, serum total protein and albumin levels were estimated by standard method. Statistical analysis was done by one way ANOVA, Bonferroni and Pearson’s correlation coefficient test as applicable. Results: Serum Cu levels were significantly higher in all trimesters of pregnant women compared to control. Again, this value was significantly higher in 3rd trimester than that of in 1st and 2nd trimester and also in 2nd trimester than that of in 1st trimester. In addition, mean serum total protein level was significantly lower in 3rd trimester than control but no statistically significant difference was observed among different trimesters. Again, mean serum albumin level was significantly lower in 2nd and 3rd trimester than 1st trimester and control. In addition, serum Cu concentration showed significant positive correlation with different trimesters of gestation. Conclusion: This study reveals that hypercupremia along with hypoproteinemia occur in pregnant women from 1st to 3rd trimester of gestation. This gradual alteration of micro and macronutrients become more profound with advancement of pregnancy.
