Carcass Traits Association with GH/ Aini Gene Polymorphism in Indonesian Aceh Cattle

Abstract

This study was conducted in order to ident~fj,1 polymorphism ofgrowth hormone gene in the exon five and to determine the association of GH/Alul polymorphism with carcass quality in Aceh cattle. A total of 42 DNA genome samples were extracted from two Aceh cattle population, i.e., Banda Aceh ( 12), Aceh Besar (3q), and the PCR-RFLP was used to amplifj; 404 bp of GH gene. The result showed that the LL genotype was the only genotype found in Aceh cattle population, and the alelefrequency of alel Lis 1. This.finding indicated that there was not evidence of polymorphism of GH/Alul in Aceh cattle, and there was not correlation of GH/Alul gene with carcass quality of Aceh cattle. It could he affected by small number of sampling size. However, this study suggests that GH gene could be possible used as genetic marker.
