Fat and cholesterol content and fatty acid composition of mares' colostrums and milk during five lactation months.

摘要

Effects of lactation stage were investigated on the fat and cholesterol contents and the fatty acid composition of colostrum and milk from Wielkopolska mares. Milk samples were collected from day 0 to 5 months of lactation. As lactation time increased, contents of fat and cholesterol in the milk decreased. Significant changes were also observed in ratios of n-6 to n-3 PUFA. Based on these observations, it is suggested that the nutritional quality of mares' milk is optimal between months 4 and 5 of lactation.
