Abstract

Studies were conducted on crossbred bulls to determine the effect of various levels of Holstein-Friesian inheritance and numbers of indigenous breed components (Sahiwal, Red Sindhi, Tharparkar and Hariana) on the reproductive wastage rate of bulls used in artificial insemination programme. It was...

AbstractFull Text

Preservation of genetic variability of local pig breeds lies on a rigorous management of matings. Semen stocks preserved in the national cryobank constitute a patrimonial safeguard intended to reconstitute breeds in case of extinction. The goal of the present experience is to use frozen semen of...
