Behavior and welfare of dairy cows submitted to drying: Review

Abstract

Drying of cows carried out about sixty days before the expected date of birthing, is considered of great importance to health, welfare and colostrum and milk production of dairy cattle. Despite it is importance, there is little information in the scientific literature on this procedure, even if it is a common practice on farms. Behavioral changes such as increased frequency vocalizations, reduced feed consumption, prolonged lying and udder apparently swollen during drying period, indicate high levels of stress and can to indicate discomfort and pain. The milking frequency and interval, as well as feed strategies are alternative available to manipulate the milk production and drying of cows. The welfare of farm animals has become a major concern for the society, therefore, drying strategies should be studied. Thus, the objective of this study was to review the importance of an adequate drying management regarding the behavior and welfare of dairy cows.
