In evaluating research on cow efficiency, it is apparent that one of the more important factors influencing the overall productivity and efficiency of the beef cow herd is reproductive efficiency. Pregnant Much research has been done indicating that many cows fail to show heat early in the breeding season and also that conception rate at first service is low. If, however, proper management procedures are utilized the number of cows showing estrus the first 21 days of breeding as well as the conception rate at first service can be high.
Cows require adequate nutrition and rest post calving in order to cycle normally.
Conception rate is higher in cows bred 60 days or more after calving. Body Condition is important in determining when a cow shows estrus following calving. Wiltbank Suckling Cows that are suckled have longer intervals from calving to first estrus. Flushing and 48-hour calf removal can be helpful in improving reproductive performance. Neither practice alone is as beneficial as a combination of the two.
