Abstract
The Egyptian buffalo has a great economic value so the aim of this study is facing many problems of production in Beheiry Egyptian water buffaloes. Its low production is a great challenge, therefore the present study is the first report on polymorphisms of Myf5, Myf6, MyHC and Fst genes and its the first study on the correlation between their SNPs and growth traits in Beheiry Egyptian water buffaloes. Of these SNPs, A309T SNP in Myf5 promoter the body weight of TT homozygous animals at age 6, 9 and 12 mo and average daily gain (ADG) at age of 3-6 mo. One SNP A52T in Myf6 exon 1 with the body weight of AT heterozygous animals at age 3, 6 and 9 mo and with average daily gain (ADG) at age from birth to 3 mo and from 3 to 6 mo. T131C SNP in MyHC 2(fast2x) gene in coding region with the body weight of CC homozygous animals at age 18 and 24 mo and with average daily gain (ADG) at age of 12-18 mo. Both SNPs in coding region of Fst gene A246G and A327G with the average daily gain (ADG) of AA/AA homozygous animals at age from birth to 24 mo. These SNPs provides a set of useful markers for selection strategy of good meat producing animals as it could be contribute in improvement of meat production of Egyptian native buffaloes and the breeding of genuine beef buffaloes in Egypt.
