摘要： The study aimed to determine the effect of different dietary selenium (Se) doses in the form of selenised yeasts on serum Se levels and serum biochemical indices in Xinjiang brown cattle. The animals were randomly divided into five groups (n = 5): NC (negative control), group A (0.3 mg Se/kg dry matter (DM)), group B (0.6 mg Se/kg DM), group C (0.9 mg Se/kg DM), and group D (1.2 mg Se/kg DM). The animals received a Se -enriched diet with jujube for three months. The results showed that serum Se levels in cattle fed higher doses of selenised yeast were significantly higher than in control cattle. Serum cholesterol, proteins, globulin, uric acid and blood urea nitrogen levels were also significantly different between the experimental and control groups. Serum triglyceride, albumin, creatinine, and total bilirubin levels did not exhibit marked differences between the experimental groups. Moreover, serum alanine transaminase, aspartate transferase, and alkaline phosphatase concentrations in cattle also varied between the experimental groups. While the increased serum Se levels were found to enhance the cellular antioxidant status in cattle, they did not provide protection against cellular oxidative stress. Based on these findings, the addition of a moderate dose of selenised yeast to cattle feed can help maintain cattle health and contribute to the production of high -quality meat.
