چکیده
The study was performed with ۴۰ Simmental cows divided into four groups (treatments). The group I received diet with grass silage, maize silage, and concentrate. Group II was fed similar as group I plus ۴۰۰ mg d-۱ cow-۱ of β-carotene. In group III, ۴۰% maize silage DM was replaced with pumpkin silage to ensure a ۴۰۰ mg higher β-carotene intake compared to the group I. In group IV, ۶۰% of maize silage DM was replaced with pumpkin silage without balancing β-carotene. Milk samples were collected at ۴ and ۸ weeks of experiment. The milk was analyzed for the basic composition, carotenoids, Total Antioxidant Status (TAS), and composition of fatty acids. In both measurements, the highest content of α-carotene, β-carotene, lutein, violaxanthin were in the milk of group IV, and the lowest in group I. In the milk groups III and IV, higher content of PUFA, including n-۳ PUFA, was found in successive samplings. In all samplings, milk TAS in group I was significantly lower compared to groups III and IV.کلیدواژه ها
