Abstract

The function of hypophysis gland, in the physiology of reproduction produces both primary and secundary hormone of reproduction which controlled by hypothalamus. This research was set up to investigate the effect of hypophysis extract level on ferning, estrous and pregnancy of ewes. The results showed that the efect of hypophysis extract, onset of long time standing of ferning, long time of estrous were highly significant (P<0,01) and the pregnancies of ewes were highly significant (P<0,01). The average of long time of estrous (hours) for T1, T2 and T3 were 26.53’; 39.33’; and 49.24’ and the percentage of pregnancy was 57,14; 85,71 and 100%. It can be concluded that the hypophysis extract increaced estrus quality and the total pregnancy. Keywords : Ewes, Hypophysis Extract, Oestrus, Fertility, Pregnancy
