Treatment of some infertility cases in Sharabi Cows

Abstract

Twenty nine infertile Sharabi cows were divided randomly into 3 groups. The cows of first group were treated by (PRID) alone for 12 days. The cows of second group receive (PRID) alongwith one dose of GnRH (200 mg), while cows of the third group received 2 injections of PGF2 and eleven days a part. Results showed oestrus after 48-72 hrs. from the end of treatment in 55.5%, 77.7% and 63.7% cases in first, second and third groups respectively. The conception rate and pregnancy of the inseminated cows were 80%, 85.6% and 71.4% for the three groups respectively.
