Haplotypes of Single Nucleotide Polymorphisms (SNPs) in casein loci of Girgentana goats explain isoelectrofocusing results.

Goat milk, cheese and yoghurt offer an alternative to cow milk products. In Sicily one of the important goat breeds reared is the Girgentana. Traditionally the milk from Girgentana goats was used for nourishment of infants and elderly. Recently, the Girgentana breed has been in decline. This of concern, as the Girgentana may carry unique milk protein genetic variants. If health benefits of Girgentana goat milk is proven, then increasing production from this population will be of great interest. The most abundant proteins in goat milk, as in other milks, are the caseins, αS1-, β-, αS2- and κ-casein, coded by the loci CSN1S1, CSN2, CSN1S2 and CSN3 respectively. In other goat breeds, the casei…
