Study of growth hormone gene and its relationship to Weaning weight in Goat

Abstract

Abstract Experiment was conducted in Ruminant Research of the Department of Agricultural Research Station/ MOA located in Abu Grib (23 km) west of Baghdad, for the period from 09/20/2012 till 30/09/2013 for the season a productive one 2013 conducted laboratory work in bio-technology center/ University of Nahrin. It was analyzed 206 record a return to breed local goats 64 record and strain Cypriot goats 142 record in order to study the growth hormone gene relationship with birth weight. The number of genotypes in goats animals Cypriot samples with the highest merit and hereditary recipe weaning weight AB 9 + AA 1 compared with the Cypriot goat animal samples with the lowest merit and hereditary recipe weaning weight AB 8 + AA 2, and the number of genotypes in domestic animals goat samples with the highest merit and genetic recipe for weaning weight AB 7 + AA 3 Compared with domestic animals, goats samples with at least deserved a genetic recipe for weaning weight AB 8 + AA 2. Infer genotypes between the local goat breed with Cypriot goat breed for type genotypes for Jane growth hormone, and there are two models and Rathein two AA and AB shows allele AB in both strains and repeated Jenny loud while allele AA appears less frequently in both strains, the possibility of the use of genotypes to the hormone growth as markers for the animals with high productive performance for use in herd improvement, especially local ones
