The transition period in dairy cows is a critical phase influencing their health, immune function, and overall productivity. Recent studies have highlighted the importance of methionine supplementation during this time. Research shows that rumen-protected methionine (RPM) enhances immunometabolic health by altering gene expression in blood, liver, and endometrial tissues. These changes boost immune responses, reduce oxidative stress, and improve metabolic status, resulting in better performance during early lactation. Maternal supplementation also positively affects offspring, influencing calf immune function and metabolism. These findings underscore the role of RPM in optimizing dairy cow health and productivity, particularly during the peripartum period.
