Development of a New Kisspeptin Based Method of Ovulation Synchronization for Crossbred Dairy Heifers
Abstract: The aim of the present study was to develop a new method of synchronization of estrus/ovulation for crossbred cows based on kisspeptin, a potent secretagogue of GnRH. For the purpose, a total of 108 estrous cycles were studied in cyclic heifers. The animals divided equally in to two groups were treated either with ovsynch protocol of estrus synchronization (group-I; GnRH: day 0; PGF2α: day 7 and GnRH: day 9) or …

Heterosis–Genetic Basis and Utilization for Improvement of Dairy Cattle: A Review
Abstract: The phenomenon in which progeny of crosses between inbred lines or purebred populations are better than the expected average of the two populations or lines for a particular trait is known as heterosis. Utilization of heterosis is the main goal of crossbreeding. The amount of heterosis maintained in a herd depends on the type of crossbreeding system selected for breeding. Heterosis includes greater viability, faster growth rate and greater milk …

Use of Area Specific Mineral Mixture to Ameliorate Region Specific Reproductive Problems in Ruminants
Abstract: Reproductive inefficiency in ruminant cows is one of the most important global problems affecting the profitability of the farm. Some trace minerals like Ca, P, Cu, Zn, Co and Mn have important roles to maximise reproductive performances. Even marginal deficiency of these minerals can impair reproduction showing clinical signs of deficiency. Effects of mineral deficiency and metabolic disorders in all categories of dairy animals have been observed due to lower …
