Association of β-casein gene polymorphism with milk composition traits of Egyptian Maghrebi camels (Camelus dromedarius).

ABSTRACT: The objectives of this study were to detect the polymorphism of 2126 A/G SNP in the β -casein (CSN2) gene among Egyptian Maghrebi camels and to investigate the association of 2126 A/G SNP genotypes, parity, lactation stage, and temperature-humidity index (THI) with the milk composition traits of Maghrebi camels. Sixty-eight hair samples were collected from three different populations of Maghrebi camels for DNA extraction. Fat, protein, total solids, solids-not-fat, and lactose percentages were determined in Maghrebi camel milk using an automatic milk analyzer device. Three different genotypes - A/A, A/G, and G/G - were identified in the 5 ' flanking region of β -casein gene by using PCR-RFLP method with the A/G genotype showing the highest frequency. Association among these three genotypes
