ABSTRACT

Calving interval is the best overall measure of reproductive efficiency. A shorter calving interval leads to higher milk production per day of life in the herd and more replacements born in a cow's lifetime. Cows should calve in a clean, dry box stall. Delivery of a calf into unsanitary conditions puts that calf at an immediate disadvantage for survival. Cystic ovaries are a common reproductive problem in all dairy herds. Postpartum reproductive management of dairy cows requires conscientious planning, observations and good records. Calving interval is the best comprehensive measure of efficiency. Constant striving for increased reproductive efficiency leads to increased profitability in the dairy enterprise. Some producers are tempted to infuse all postpartum cows. Reports from the field suggest that an increasing number of dairymen are regularly infusing cows after artificial insemination.
