Changes in feeding behavior, milk yield, serum indexes, and metabolites of dairy cows in three weeks postpartum.

ABSTRACT: Parturition and lactation stress greatly affect physiological and metabolic status of postpartum cows. Monitoring feeding behavior can help assess the health status of postpartum cows. This study aimed to explore the changes in feeding behavior, milk yield (MY), serum indexes, and metabolites of dairy cows during three weeks postpartum. Furthermore, the relationships between feeding behavior, milk yield and serum metabolites were investigated. One hundred seventy-eight healthy multiparous Holstein dairy cows were enrolled to continuously record feeding behavior variables, including feeding time (FT), frequency of feeding (FF), and average feeding time (AFT), using the Nedap neck collar devices, wherein the milk yield was recorded. Out of 178 Holstein dairy cows, 20 cows with the same parit
