Technology Adoption Using PGF2 Alpha for Breeding

Abstract

The productivity and health level of goats kept are still relatively low. This is because the maintenance system carried out by farmers is still traditional and there is no touch and technology adoption. The limited scale of ownership coupled with the spread of cage locations makes it difficult to detect estrus/estrus, the absence of superior males also causes a decrease in the genetic quality of livestock. This study aims to find a method of breeding in sheep using reproductive engineering mating techniques to obtain an applicable goat breeding model. Research Design 10 ewes that are not pregnant, prepared for natural mating with the joint bull mating model. The treatment for the ewes was prepared for estrus synchronization reproductive technology using prostaglandins with two doses. The livestock group was induced by intramuscular estrus as much as 0.5; 1; 1.5; and 2 cc per head using the hormone PGF2 alpha (lutalyse). The injection is done with two injections (double injection) with an interval of 11-12 days. Two days after the application of the hormone, the goat showed estrus, then observed the percentage of estrus, estrus intensity and estrus strength. The results showed that all doses that had been given gave good results on the onset of estrus, standing heat, duration of estrus, intensity of estrus and after the second injection with a distance of 11 days all treatments showed 100 percent estrus. Days 14 to 18 after treatment were the peak period with the highest intensity of estrus and standing heat in goats. Giving a dose of prostaglandin 2 ml has been effective and more economical in estrus synchronization to produce quality estrus symptoms.
