Abstract

This study aimed to explore how pasture periods and parity impact the lipid profiles of 38 Awassi sheep raised in a traditional grazing system on natural pastures. Milk samples were gathered for lipid profile analysis at the commencement, midpoint, and conclusion of the pasture period. Data analysis employed repeated measurements through two-way ANOVA within the General Linear Model (GLM) framework. The statistical model encompassed the effects of pasture periods, parity, and their interactions. Although parity did not affect lipid profiles, the pasture period had a significant effect (p<0.01) on triacylglycerol (TAG), free fatty acid (FFA), and monoacylglycerol (MAN). A significant effect (p<0.05) on cholesterol (COL) was also observed. Furthermore, neither pasture period nor parity had any effect on phospholipids. As a result of the study, it was determined that parity had no effect on the lipid profile in milk, while pasture period had a very significant effect on triacylglycerol, free fatty acids, monoacylglycerol and a significant effect on cholesterol.
