Abstract: Twenty Xinjiang Brown cows were allocated to two treatment groups with 40 d periods to determine whether supplement with tomato pomace fermentation feed (CP≥26%, DM) would influence anti-oxidation or immunity of serum and milk. Treatment diets were control diet and 6% cotton seed meal (DM),4.5% wheat bran (DM),3.5% corn silage (DM) of the control diet replaced with 14%(DM) tomato pomace fermentation feed. Cows were fed a basal TMR formulated and the control diet The supplement with tomato pomace fermentation feed significantly increase the activities of T-SOD,GSH-Px in the serum,the amount of TAOC in the serum, and significantly decrease the amount of MDA in the serum(P＜0.05).There were an increased tendency in the activities of T-SOD,GSH-Px and the amount of TAOC in the milk when the diet was supplemented with tomato pomace fermentation feed.The supplement with tomato pomace fermentation feed significantly increase the amount of IgG, IgM in serum(P＜0.05), while there were no significant increase in the amount of IgG, IgA, IgM of the milk. Th ere were an increased tendency on the activities of IgA in the milk when the diet was supplemented with tomato pomace fermentation feed.This suggested that tomato pomace fermentation feed could increase the anti-oxidation and immunity, which was a kind of much better feed.
