Obtaining Frozen Semen of Bulls with Superior Qualitative Parameters

Abstract

Sperm is a zootechnical production that is harvested, controlled, processed and used, within a well-defined technological stream.Biotechnological intensification of breeding to increase birth and prolificity in zootechnics requires complex control of spermatic production on scientific bases in accordance with current legislation and compliance with national and international standards. In this regard, complex control of sperm production, regardless of its origin, is required by performing ordinary and special spermograms. In the modern technological flow of artificial cattle insemination, processing by dilution is an essential step with obvious zooeconomic implications, because it greatly increases the number of usable doses obtained from an ejaculate, increases the possibility of insemination a much bigger number by larger females, directly contributing to increased male selection pressure.
