Effect of Extenders and Storage Period on Fertilization Rate

Quality seed production is decreasing day by day due to inbreeding, hybridization, negative selection and unscientific management for breeders etc.Consequently, the original genetic status of the species has been degraded or genetically introgressed in the hatcheries through unwanted human interferences. Therefore it is necessary to stop any kind of further degradation of the stock and at the same time to conserve the genetic resources. The selection of best quality semen is the prior most to preserve the sperm.The preservation ways may be two types.One is cryo-preservation which is costly and sophisticated equipment dependent and another one is short-term preservation.In this book, our aim were to develop a protocol to identify quality sperm as well as protocol for short-term preservation of sperm which ultimately reducing the genetic introgression and enhance the production.
