Management of Bull and Planning of Germplasm Centre

The advent of Artificial Insemination (AI) has considerably enhanced the scope of propagating the superior garmplasm of domesticated animals. Early use of it was considered as a means of controlling venereal disease and utilizing bulls unable to mate successfully. With the development of semen extenders, a single collection of semen could be extend by a factor 100 or more to increase number of progeny from a single superior sire.

Progress in the science of low temperature biology has made it possible to store a wide variety of living cells for a prolonged period at a very low temperature. Developments in successful freezing and storage of semen further stimulated the adoption AI especially for cattle.

Leading spermatozoa to a state of quiescence by reversible reduction of metabolic activity of spermatozoa at the time of collection and subsequent method used for inactivation, revival and utilization. The processing of semen starts with the bull and ends with the cow. This necessitates a high level of cooperation and coordination among the person engaged in management of bulls, handing semen both in laboratory and field, and in collection, assessment and interpretation of data.

Following are the topics given below in relation with management of Bull and Germplasm centre:

• Management of Frozen Semen and Semen Bank
• Layout of Semen Bank Management of Laboratory
• Management of Breeding Bulls
