Abstract

The aims of Science and technology for society (IbM) on UMKM are as follows: 1) Estrous Syncronization in goats using PGF2a 2) Superovulation in goats using PMSG and HCG 3) goat genetic improvement through artificial insemination using fresh semen 3) pregnancy rates as the result of Al 4) litter size and sex ratio of the goatling as well. Twenty five goat were synchronized using PGF2a dose of 5 mg'tail in this research. Treatment was conducted twice interval of 11 days. Goats showing symptoms of estrus after the second injection of PGF2a were treated by artificial insemination using fresh semen of male Crossbred Etawa. Treatment was conducted twice interval of 11 days Ten goat were synchronized using PGF2a dose of 5 mg/tail and superovulation PMSG dose 500 IU and HCG 250 IU in. this research. Goats showing symptoms of estrus after the second injection of PGF2a were treated by artificial insemination using fresh semen of male Crossbred Etawa. After Estrous Syncronization to 25 breeding goats using PGF2a, total estrous goats from the first injection of PGF2a were 15 individuals (60Y6) and total estrous goats from the second injection of PGF2a as many as 25 tails (10096). The occurrence of pregnant goat after AI using fresh semen were 21 individuals (8476) and non-pregnant goats were 4 tails (1696). The total litter size were 42 tails, with the number of survived goatling were 40 individuals (95,23Y6) and the number of mortality were 2 individuals (4,7796). Sex ratio showed that the comparison between male and female lamb was 25 tails (62,50Y6) to 15 tails (37,50Y6). After Estrous Syncronization to 10 breeding goats using PGF2a and superovulation using PMSG and HCG. The occurrence of pregnant goat after AI using fresh semen were 8 individuals (80Y6) and non-pregnant goats were 2 tails (2096). The total litter size were 26 tails, with the number of survived goatling were 23 individuals (88,4674) and the number of mortality were 3 individuals (11,5496). Sex ratio showed that the comparison between male and female lamb was 12 tails (52,17”0) to 11 tails (47,83Y2). Keywords : synchronization, superovulation, artificial insemination, fresh semen, crossbred Etawa goat
