Effect of melatonin on maturation capacity and fertilization of Nili-Ravi buffalo (Bubalus bubalis) oocytes
This study evaluated the effect of melatonin supplementation of in vitro maturation media on in vitro maturation (IVM) and in vitro fertilization (IVF) rate of buffalo oocytes. Cumulus oocytes complexes (COCs) were aspirated from follicles of 2-8 mm diameter. In experiment I, COCs were matured in IVM medium supplemented with 0 (control), 250, 500, and 1000 μM melatonin for 22-24 hours in CO2 in...
متن کاملSemen 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 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 کاملEffect of age and season on some semen parameters of Nili-Ravi buffalo (Bubalus bubalis) bulls
This study was carried out on 16 buffalo bulls (Bubalus bubalis) divided into four age groups, including three healthy (less than 5, 6-10, and more than 11 year old animals), and one abnormal group (6-10 year old bulls having poor semen quality). The study was undertaken for a one year period divided into five seasons (dry summer, humid summer, autumn, winter and spring). Overall semen volume w...
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...
