...ahexaenoic acid (DHA) on frozen-thawed quality of bull semen. Twenty-four ejaculates (8 from each bull) were collected from three bulls. Semen ejaculates having motility ≥70% and normal morphology ≥80% were extended into Tris extender consist of equal concentration of each ALA and DHA (0, 3, 5, 10,15ng/ml). Extended semen was cooled at 5oC for 2 hours at 5oC and then packaged in 0.25ml straws and stored into liquid nitrogen for 24 h...

... extender on chilled and frozen thawed quality of Kundhi buffalo bull semen. After collection ejaculate was brought in Semen Production Unit. Semen was evaluated as fresh for volume, colour, motility, morphology, live dead ratio, membrane integrity and sperm concentration, post chilling for motility, morphology, live dead ratio, membrane integrity and frozen thawed for motility, morphology, live dead ratio and membrane integ...
