Abstract

The purpose of this study are to determine the opti mum dose of the use of Medroxy Progesterone Acetate (MPA) combined with estrogen by intramuscular (IM) on Fat Tailed Sheep and to determine the use of MPA combined with estrogen IM in Fat Tailed Sheep can lead to estrus.It takes as many as 20 Fat Tailed Sheep females who have confirmed once lambing and more than one year of age, who were randomly divided into four groups with each treatment get five replications. After administration of MPA and when estrus as much as 5 cc of blood drawn for examination levels of progesterone and estrogen blood serum with RIA method.The results achieved from this research on Fat Tailed Sheep is that the injection PGf2α 20 mg in the control and injection of MPA 100 mg + 10 mg estradiol benzoas (P1), 75 mg + 10 mg estradiol benzoas (P2) as well as 50 mg + 10 mg estradiol benzoas (P3) is effective for estrus induction in Fat Tailed Sheep. Time onset of estrus symptoms occurred one day after the administration of estradiol benzoas. There is a tendency MPA dose of 75 mg + 10 mg estradiol benzoas is the most effective dose to induce estrus in Fat Tailed Sheep
