Abstract
The study was conducted on a sample of 30 local goats in Diyala governorate / Canaan district in one of the
goat breeders' fields in the region for the period from 13/11/2022 to 1/5/2022 to determine the genotype of the
gene STAT5A EXON-7 and Its relationship to milk production (daily milk production-DMP and total milk
production-TMP) and growth traits (birth weight-BWT, weaning weight-WWT and total weight gain-TWG).
The analysis showed three-point mutations (CC=18 CT=12 C47064T AA=17 AT=13 A47088T and GG=15
GA=15 G47162A). There was no significant effect of the genotypes of the three mutations on all studied traits
DMP, TMP, BWT, WWT, TWG, and body dimensions of the newborn at birth and weaning, body dimensions
of the newborn at birth and weaning.
Keywords: Local goats, milk production, gene STAT5A EXON-7.
