Culling Dairy Cows Deciding when to cull a dairy cow is sometimes not an easy task. Each dairyman, either consciously or unconsciously, has certain criteria that he uses in making this decision. Sometimes the decision is based upon the cow that was the latest problem to the dairyman. This may be a valid reason, especially if the cow has had a history of being a problem animal. Dairymen should develop a checklist of culling reasons to use in their decision making process. The following list of 10 questions is one that could be used for each cow before deciding her future in the herd. 1. Is her yearly production 20 percent or more below the herd's DHI rolling average? Another way of evaluating her milk production ranking in the herd is to compare her daily production amount with the average for the herd. Is her daily production 50 percent or more below the average produced daily per milking cow in the herd? 2. Is she a chronic mastitis case? Check this one closely, because a cow with chronic mastitis is producing below her capability and, in addtion, could be spreading mastitis to other cows in the herd through the milking equipment. 3. Will she be dry four months or more? Long dry periods are costly to the dairyman and may indicate the cow has a problem of becoming pregnant, a trait not desired. 4. Is she a hard milker? Is her udder shape or teat structure such that she is a nuisance to milk? 5. Does she have a history of calving difficulties or post calving illnesses such as retained placenta, metritis, or milk fever? Cows that cause problems at calving time are not pleasant to have and are costly to keep in the herd. 6. Does she have an undesirable disposition? Is she a nervous cow or does she kick whenever her udder is touched? These are undesirable traits that should be noted along with production and calving problems. 7. Is she below the herd's average
