Semen Characteristics as Influenced by Seasonal and Climatic Variations in Nili-ravi Buffalo Breeding Bulls
The present study was conducted to determine the effect of seasonal and climatic variations on semen characteristics of Nili-Ravi buffalo breeding bulls in Sahiwal and Bahawalpur districts of Punjab, Pakistan. For this purpose, 14 adult NiliRavi buffalo breeding bulls (n=7 from each of Semen Production Unit (SPU) Qadirabad, Sahiwal and SPU Karaniwala, Bahawalpur), were used. Semen samples were ...
متن کاملΒ(1,4)-galactosyltransferase-i Gene Polymorphisms in Pakistani Nili Ravi Buffalo
β4GalT-I interacts with α-lactalbumin to form the lactose synthase in mammary gland. Considering the biological function of the lactose synthase complex, β4GalT-I gene can be considered as a candidate gene for milk production in dairy animals. The bovine β4GalT-I gene, 3,283 base pairs in length, is mapped on chromosome 8. The present research work was planned to identify the polymorphism in β4...
متن کاملMolecular Marker Assisted Study of Kappa-casein Gene in Nili-ravi (buffalo) Breed of Pakistan
The present study was conducted to investigate the existence of polymorphism at Kappa-casein (κ-CN) locus in the Nili-Ravi buffalo. A PCR-RFLP method was used to distinguish buffalo κ-CN alleles. The genotypes were confirmed through specific, clearly distinguishable DNA band pattern resulting from digestion with three selected restriction enzymes (HinfI, HaeIII and MaeII). Analysis of 163 anima...
متن کاملAssessment of Nili-Ravi buffalo (Bubalus bubalis) semen by MTT reduction assay
MTT (3-(4,5-dimethyl thiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assay is commonly used to validate the viability of metabolically active cells. The study was conducted to examine and validate the MTT test to assess the sperm viability of Nili-Ravi buffalo bulls and compare the efficiency of the test with the supra-vital staining technique (eosin-nigrosine) and hypo-osmotic swelling test. F...
متن کاملSome of the Risk Factors of Nili-ravi Buffalo (bubalus Bubalis) Neonatal Calf Mortality in Pakistan
This study was carried out to investigate neonatal calf mortality (NCM) in 864 Nili-Ravi buffalo calves born during 1993-2000 at the Livestock Production Research Institute (LPRI), Bahadurnagar, Okara, Pakistan. The overall mortality in buffalo neonates was 9.4%. The NCM in relation to birth weight, sex and age of neonatal calf showed non-significant difference. The highest mortality was record...
