Dataset: Effects of Feeding High-moisture Corn on Milk Quality, Serum Antioxidant Indices and Intestinal Microflora of Chinese Holstein Cows

This study investigated the effects of replacing steam-flaked corn (SFC) with high-moisture corn (HMC) in the diet of Chinese Holstein dairy cows. Forty mid-lactation cows (parity 2-3) were randomly assigned to two groups: in the control group (YPFY group, n=20), cows were fed a diet containing SFC, while in the treatment group (GSFY group, n=20), cows were fed HMC with equal dry matter (n=20), with both diets being isoenergetic and isonitrogenous. The experiment included a 10-day adaptation followed by a 60-day feeding period. Milk components, serum antioxidant enzymes, and gut microbiota were assessed. Results showed that although milk yield was unaffected, the GSFY group exhibited a marked increase in milk fat percentage (P
