Comparative fatty-acid profile and atherogenicity index of milk from free grazing Nguni, Boer and non-descript goats in South Africa

摘要

This study aimed to determine and compare the fatty acid composition and atherogenecity index of milk fat from Nguni, Boer and non-descript at two different sampling periods. The goats ( n ?=?10 for each goat genotypes) were raised under an extensive system of husbandry. Milk samples were collected from each individual goat to determine fatty acids, as methyl esters, using gas chromatography. The result revealed significant differences ( P ?
