Abstract

A total of 390 samples of female genital tract were examined from cattle of different age and breeds, of which 156 were found to have various abnormalities. Out of these, 64 samples revealed pathological lesions in the uterus, of which 1 case (0.64%) was of adenomyosis. Microscopically, foci of displaced endometrial glands were noticed either in single or numerous groups, superficial or deep extending into the myometrium and endometrial glands were present in myometrium.

Abstract

The present was undertaken during period of June to December, 2015 to elucidate the occurrence of renal abscesses in sheep. A total number of 1,298 specimens of kidneys of sheep were examined irrespective of age, sex and breeds in North-West Rajasthan. Out of these, 211 specimens of kidneys suspected for abnormalities were further processed for histopathological examination. This condition was recorded in 4 (1.89 per cent) cases. Grossly, kidneys showed multiple small abscesses, these were firm, white and slightly raised. Cut section revealed creamy inspissated granular pus surrounded by thick coat of fibrous tissue. Microscopically, multiple abscesses were seen in the cortical regions which contain thick cellular detritus in the centre surrounded by cellular infiltration consisting mainly lymphocytes and macrophages with few polymorphs at the inner margin and encapsulated by a well defined connective tissue capsule.

Abstract

The aim of this study was to determine the incidence and haemato-biochemical studies on goats naturally infected with coccidiosis in a semi arid region, India. Out of the 153 faecal samples collected directly from the rectum of goats and examined for the presence of oocysts 126 (82.35%) were found to be positive for coccidian oocysts. Eimeria species were identified after sporulation of oocysts present in the faecal by keeping in a thin layer of 2.5% aqueous potassium dichromate for 2-8 days at 280 C in laboratory. Based on morphometric studies, a total of five Eimeria species were identified, i.e. E. arloingi (44.12%), E. ninakohliakimovae (27.62%), E. hirci (15.51%), E. christenseni (8.62%) and E. caprina (4.62%). Haematological changes include a significant (P>0.05) reduction in erythrocyte count and haemoglobin content. Also, there was a significant leucocytosis. Biochemical analysis showed a significant decrease of glucose and alkaline phosphatase.

Abstract

Present study evaluated the variations existing between the techniques of evaluation of acrosomal integrity in bull spermatozoa. Acrosomal integrity was evaluated in forty ejaculates collected from four Haraina bulls using traditional Giemsa staining (n=20) and fluorescent FITC-PSA labeling (n=20). Evaluation of intact acrosome and damaged acrosome

followed by different types of acrosomal damage (primary, secondary and tertiary) were carried out using these techniques. Results revealed that FITC-PSA labeling technique is better as compared to Giemsa in evaluation of intact as well different types of acrosomal damage. Simultaneously, we noted significantly better analysis of acrosomal intactness on Poly-L-Lysine coated slides as compared to general glass slides. The ease of preparation of smears and their evaluation was better on Poly-L-Lysine coated slides as compared to general glass slides. From the study, it was concluded that, evaluation of spermatozoa for identification of different types of acrosomal damage may be preferred to be evaluated by FITC-PSA as compared to Giemsa and Poly-L-Lysine coated slides may be preferred for better analysis of results. The study is beneficial to the scientific community in terms of staining as well as better interpretation of acrosomal status in animals.

Abstract

The present experiment was designed to study the effect of single subcutaneous melatonin (MLT) administration on induction of estrus and pregnancy establishment in Singharey (Sikkim local) goats during non-breeding season. Forty clinically healthy female goats of 2-5 years of age, had kidded at least once were selected and grouped as: Group (I): single subcutaneous injection of sterilized corn oil as control (n=10), Group (II): single subcutaneous injection of MLT @ 10 mg in sterilized corn oil (n=10), Group (III): single subcutaneous injection of MLT @ 20 mg in sterilized corn oil (n=10) and Group (IV): single subcutaneous injection of MLT @ 40 mg in sterilized corn oil (n=10). Estrus induction response was 20%, 80%, 100% and 30% in group-I, II, III and IV, respectively. Estrus induction interval (in days) was 16±5.00, 11.25±1.96, 14.20±0.77 and 13.60±4.06 in group-I, II, III and IV, respectively. Kidding rate was 100% in group-I, II and IV while it was 80% in group-III. The litter size (median) was 1.5, 2, 1.5 and 2 in group-I, II, III and IV, respectively.

Total live kids born were 3 in group-I, 16 in group-II, 13 in group-III and 5 in group-IV. Therefore, it can be concluded that single subcutaneous injection of melatonin @ 10 mg was an effective strategy for inducing out of season breeding in this breed with increased fecundity.

Abstract

Considering the insufficiency of morphological assessment for evaluation of oocytes, other evaluation parameters like glucose-6-phosphate dehydrogenase (G6PDH) activity are becoming popular. The present experiment was conducted to study the effect of follicular size on G6PDH activity of buffalo oocytes. The overall average of BCB+ (inactive G6PDH) and BCB- (active G6PDH) COCs in the present study was recorded to be 51.68±1.25 and 48.32±1.25%, respectively. The BCB+ COCs in large follicle (56.42±0.47) was significantly (p<0.01) higher as compared to small follicles (45.82±0.56). The reverse was observed in BCB- COCs where significantly (p<0.01) higher proportion of BCB- COCs was recorded in small follicle (54.18±0.56) as compared to large follicles (43.58±0.47), thus indicating better developmental competence of oocytes derived from large follicles.

Abstract

The present study was designed to evaluate the effect of different O2 concentrations on the developmental potential of tetraploid embryos. For production of tetraploid embryo, 2-cell embryos were obtained by the method of in vitro fertilization. The produced 2-cell embryos were exposed to different O2 concentrations at 1.2 kV/cm field strength and 4 μs pulse duration and their fusion rate and subsequent developmental stages were compared. When the effect of different oxygen concentrations was evaluated, it was observed that maximum cleavage (82.35%) was recorded at the 5% oxygen concentration and 4.76% of the embryos developed upto the blastocyst stage. It was concluded that 5% oxygen concentration was the most suitable treatment for production of tetraploid embryos.

Abstract

A total of 11 breeding male camels having Body Condition Score (BCS) between 3.0 and 3.5 were selected for breeding of female Camels (n=65) having BCS between 2.5 to 4.0. The period of mating was from December to March 2015. Each male camel was enabled to mate with minimum 3 to maximum 9 female camels. Physical changes and reduction in body weight was observed in all breeding camels except few camels whose frequency of mating was restricted. The females having exceptionally high body condition score were found to be inconvenient for mating and bulls were reluctant to mount such females. Repeated mounting and demounting by males is common in high body BCS females. The study found that females having BCS between 2.5 and 3.5 were comfortable due to prominence of coxial and Ischial tuberocity leading to locking of chest pad between these and rear side of hump. The present findings indicated that high BCS females were not convenient for mating and chest pad played role in mating behavior by providing a lock between hump and ischial tuberocity.

Abstract

For studying the role of leptin hormone around parturition and to evaluate its association with other biochemical profile in high yielding primiparous Indian cow, six primiparous pregnant Sahiwal cows of same age group and body condition score were selected. The blood samples were collected from these cows on 30 day prepartum, day of parturition and on 30 day postpartum and plasma was harvested. The plasma samples were further analyzed for levels of leptin hormone, non-esterified fatty acids (NEFA), glucose, triglycerides (TG), cholesterol, high density lipoprotein (HDL), low density lipoprotein (LDL), total plasma protein (TPP), albumin, urea, creatinine, calcium (Ca), phosphorus (P) and potassium (K). The results of plasma leptin, TG, cholesterol, HDL and LDL showed highest level of leptin in late pregnancy (-30 days) which significantly declined to nadir at parturition then rose around to prepartum levels at 30 days postpartum. The NEFA concentration increased from pregnancy to calving and later decreased to achieve prepartum

levels during lactation. The levels of plasma TPP, albumin, globulin and P were highest in pregnancy which declined to nadir at parturition and remained almost unchanged during lactation. Creatinine and Ca concentrations remained unchanged from pregnancy to parturition and then significantly reduced during lactation while urea was significantly lower during pregnancy and rose in lactation. The overall correlation of LEP with biochemical profile revealed positive correlation with TG (r = 0.8), cholesterol (r = 0.69), HDL (r = 0.67), LDL (r = 0.52), globulin (r = 0.56) and P (r = 0.59) while negative correlation with NEFA (r = -0.90) and AG ratio. In addition leptin showed negative correlation with creatinine during pregnancy and lactation. In conclusion, the variations in leptin hormone and other biochemical profiles from pregnancy to lactation, and association of leptin hormone with biochemical profile suggesting its significant physiological role in energy metabolism, body mass and immunity of dairy cows during this crucial period.
