The gradual disappearance of Sudanese indigenous goat breeds in numbers over the last years is due to the displacement by other breeds, cross-breeding with exotic breeds or with other indigenous breeds. To prevent the irreversible loss of Sudanese indigenous goat breeds which are well adapted to the local environment, breeding improvement and conservation strategies for these breeds should be based on a combination of phenotypic and genetic characteristics. Therefore, milk protein genetic variations are useful functional markers for characterising breeds. The objective of this study was to assess the allelic variation of alpha-lactalbumin (LALBA) gene of Sudanese goat breeds including Nubian, Desert, Taggar and Nilotic goat breeds. The α-lactalbumin is a subunit of lactose-synthase, an enzyme responsible for lactose production, a disaccharide that influences milk production.
