Abstract

Various fertility parameters, plasma progesterone and oestradiol 17 beta concentrations were investigated in Angora Goats receiving gonadoreline immediately or on 12th day after breeding. A total 48 cyclic, pluriparous Angora Goats, 2-5 years of age were divided into 3 groups. The first group received 100 mu g gonadorelin immediately after breeding. The second group received 100 mu g gonadoreline on the 12th day after breeding and the third group receiving no injection served as the control. Jugular blood samples were collected from ail goats during the days 13 to 16 after breeding and plasma progesterone and oestradiol 17 beta levels were determined by EIA.
