Effects of γ-Aminobutyric Acid on Growth Performance, Immunity, Antioxidant Capacity, and Intestinal Microbiota of Growing Minks

The present experiment was conducted to investigate the effects of γ-aminobutyric acid (GABA) on the growth performance, immunity, antioxidant capacity, and intestinal microbiota of growing minks. One hundred minks were evenly allocated across five groups, with each group consisting of 10 males and 10 females. The minks in these groups were fed a basal diet supplemented with γ-aminobutyric acid (GABA) at 0 (control), 10, 20, 30, and 40 mg/kg of diet, respectively. The experiment lasted for eight weeks. The results showed that GABA significantly affected immunity, antioxidant capacity, and intestinal microbiota (
