Selenium (Se) is an essential trace element in the animal body, which is involved in regulating the body's antioxidant defense, immune response and reproductive performance, and plays an important role in animal health. The aim of this study was to investigate the effect of yeast selenium added to feed on growth performance, antioxidant performance, immune performance and rumen microbes of Inner Mongolian cashmere goats. 18 male Inner Mongolian cashmere goats (47.1 ± 1.1) kg, (24 months of age) were selected and randomly divided into two groups, the normal feeding group (CON group) and the yeast selenium supplementation group (0.4 mg/d, Se group) (n = 9 in each group) for 30 days of the experiment. The results showed that the average daily weight gain of Se group was significantly higher than that of CON group (P < 0.05). In addition, the levels of glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), immunoglobulin IgA and IgG in the blood and semen of the Se group were also significantly higher than those of the CON group (P < 0.05). Dietary supplementation of yeast selenium mainly increased the abundance of Bacteroidales_RF16_group, p-251-o5, UCG-004 and UCG-010 in the rumen (P < 0.05). Pearman's correlation analysis showed that Bacteroidales_RF16_group, Bacteroidales_RCG-004, and Bacteroidales_RCG-010 significantly affected the rumen microbiota and fermentation parameters, and significantly increased the antioxidant and immune capacity of plasma and seminal plasma (P < 0.05). This study provides some data support for supplemental yeast selenium in healthy breeding of Cashmere goats.
