Abstract
This study aimed to access the effect of heat stress on milk yield, antioxidative levels, and serum metabolites in primiparous and multiparous Holstein dairy cows during the early lactation stage. A total of 200 cows were selected based on their month of calving (June, temperature humidity index (THI) = 66.72; July, THI = 70.30; August, THI = 69.32; September, THI = 67.20; October, THI = 59.45). Blood samples were collected on days 0, 21, 50, 80, and 100 after calving for serum oxidative status analysis and milk yield was recorded daily. The lower average daily milk yield was recorded among the cows that calved in June and July (P < 0.05), and the average daily milk yield of multiparous cows was higher than that of primiparous cows that calved in the same month (P < 0.05) from d1 to d100, suggesting that seasonal (June, July) heat stress negatively affected milk yield in both primiparous and multiparous cows at early lactation. The study also indicated that there was seasonal variation in most of the serum metabolites across the studied months. The study shows that heat stress (average THI = 70.30) was higher among the cows calving in June vis-à-vis those calving in October and differences were also observed among the primiparous cows and multiparous cows, respectively. These metabolites (e.g., glycine, serine, etc.) which showed significant variations were mainly involved in the pathways of aminoacyl-tRNA biosynthesis, glyoxylate and dicarboxylate metabolism, and the metabolism of glycine, serine and threonine. These data suggested that heat stress negatively affected the elevation of the serum oxidative and antioxidative index and thus badly influence milk yield. Metabolic biomarkers in serum associated with heat stress could be a reliable way to identify heat stress of primiparas and multiparas dairy cows.
