Postpartum reproductive disorders cause heavy economic losses in dairy sector. Uterine infections include endometritis, metritis, mucometra, and pyometra. Postpartum endometritis in dairy cows has been defined as inflammation of endometrium occurring 21 days or more after parturition without systemic signs of illness. The treatment of endometritis with antimicrobials has met with varying degrees of success, inconsistent recovery rate, high cost of treatment, milk disposal, emergence of microbial resistance, and reduced phagocytic activity of polymorphonuclear leukocytes In our country, around 20,000 medicinal plant species have been recorded, but more than 500 traditional communities use about 800 plant species for curing different diseases. Many herbs such as garlic, neem, ashwagandha, and turmeric have been tried for the treatment of endometritis in cows with a good success.

Aim:The present study was undertaken to standardize a convenient method for isolation and purification of β-lactoglobulin (β-lg) from cow milk keeping its antigenicity intact, so that the purified β-lg can be used for detection of cow milk protein intolerance (CMPI).Materials and Methods:Raw milk was collected from Gir breed of cattle reared in Haringhata Farm, West Bengal. Milk was then converted to skimmed milk by removing fat globules and casein protein was removed by acidification to pH 4.6 by adding 3 M HCl. β-lg was isolated by gel filtration chromatography using Sephacryl S-200 from the supernatant whey protein fraction. Further, β-lg was purified by anion-exchange chromatography in diethylaminoethyl-sepharose. Molecular weight of the purified cattle β-lg was determined by 15 percent one-dimensional sodium dodecyl sulfate-polyacrylamide gel electrophoresis and was analyzed by gel documentation system using standard molecular weight marker.Results:The molecular weight of the purified cattle β-lg was detected as 17.44 kDa. The isolated β-lg was almost in pure form as the molecular weight of purified β-lg monomer is 18kDa.Conclusion:The study revealed a simple and suitable method for isolation of β-lg from whey protein in pure form which may be used for detection of CMPI.

A total of 113 diarrheic samples comprising of 68 buffalo calves and 45 cow calves were screened by RNA-PAGE for the detection of presence of rotavirus. RNA-PAGE analysis of these samples revealed 11 (9.73%) was found positive for rotavirus. Out of 68 faecal samples of buffalo calves tested for viral gastroenteritis, 8 (11.76%) were found positive for rotavirus. Similarly, out of 45 faecal samples of cattle calves tested for viral gastroenteritis, 3 (6.66%) was found positive for rotavirus. Rotavirus-positive samples represented long electropherotype. All RNA-PAGE-positive faecal samples for rotavirus subjected to RT-PCR for VP7 gene, ten samples yielded a specific product of 1,013 bp of VP7 gene. All the PCR-positive samples of the present study were subjected to genotyping with primers for G6, G8 and G10 genotype. All positive samples showed G10 genotype. This indicates that G10 may be predominant genotype among bovine calves in Mumbai region in India.

The study was carried out at the Veterinary Clinical Complex, College of Veterinary Science and Animal Husbandry, Mhow and in private clinics across Indore on 30 bitches suffering from Cystic Endometrial Hyperplasia-Pyometra Complex (CEH-PC). The animals were randomly subdivided into five groups each of six bitches and treated with bromocriptine (1 g/kg POx5 days) and cabergoline (5 g/kg POx5 days) alone and in combination with cloprostenol (5 g/kg s/c on day 0, 2 and 6) (Gr II to V) together with enrofloxacin (10-20 mg/kg PO, SID×5 days) + combination of metronidazole and povidone-iodine IU (5-10 ml×3 days), the later served as routine control Gr I.The treatment response of animals was evaluated through clinical, ultrasonographical, haematological and biochemical parameters. Blood samples were collected from cephalic or saphenous vein just before treatment (day 0) and after treatment on day 6 and day 14. Treatment approach -III (cabergoline 5 g/kg POx5 days) was found to be the most effective without side effects with significant decrease in uterine luminal diameter after treatment. The results showed significant improvement in haemato-biochemical attributes in dogs affected with CEH-P complex following treatment IV and V, i.e. with use of bromocriptine and cabergoline in combination with cloprostenol as compared to other groups.

The study was undertaken to evaluate the therapeutic efficacy of Neem (Azadiracta indica) extract in 20 infectious repeat breeder crossbred cows. Animals were divided into two groups of ten in each. The animals in first group were treated with 15% concentration of Neem extract w/v dissolved in saline to make 30 ml, Intra Uterine at 24 hrs intervals for 7 days, while the animals in control group were infused with 30 ml saline for 7 days. Bacterial count in uterine flushing declined significantly (p less than 0.05) after treatment in Neem group. A significant increase (p less than 0.05) in total cellular count and PMNs % was found in Neem group than in control group. An overall recovery rate of 80% vs 20% and conception rate of 50% vs 10% was found in Neem treated cows over control group proving its efficacy in infectious repeat breeder cows.
