Records should include all heats, even those as early as two weeks after calving. Recording all heats assists veterinarians and extension personnel who can evaluate reproductive problems when called upon for consultation. Many types of records are available. Records should include all heat dates, breeding dates, and pregnancy exams as well as any treatment the cow has received. A reproductive record should give the cow's history at a glance.
Records are also the key to a sound reproductive herd health program.
When to Breed Cows lf the reproductive tract has been examined after calving and has been diagnosed normal and free of infection, cows may be bred following 50 days after calving with little reduction in fertility. A delay in breeding may be needed for those cows having calving problems or post-calving difficulties. Don't breed cows that show any evidence of infection of the reproductive tract. Infection can usually be detected by observing the vaginal discharge. The life of the egg following ovulation is short, usually 6-10 hours with lowered fertility occurring after 6 hours.
