A feeding experiment was conducted to determine the effects of inoculating alfalfa silage with a ferulic acid esterase-producing inoculum on feed digestibility, rumen fermentation, antioxidant, and immunity status lactating dairy goats. Twenty goats were distributed into 2 experimental groups consisting control diet (Lp MTD/1, including Lactobacillus plantarum MTD/1 inoculated silage) against containing treated L. A1 A1). Alfalfa Lp had better fermentation quality than inoculation. The application improved antioxidant capacity as indicated by greater total (T-AOC), superoxide dismutase (SOD) glutathion peroxidase (GSH-Px) activities in versus treatment. Compared group, inoculation increased apparent tract digestibility dietary dry matter, organic matter crude protein, ruminal concentrations volatile fatty acids, acetate, propionate isobutyrate well. results current study also demonstrated immune performance Feeding A1-treated goats' serum antioxidase activity, such T-AOC, SOD, GSH-Px catalase, concentration immunoglobulin A, while decreased tumor necrosis factor α, interleukin (IL)-2 IL-6. In addition, compared endowed milk fat protein contents, goat without affecting efficiency.
