1. Watch for physical signs of impending labor.
As the due date approaches, cows will often exhibit physical signs that labor is near. These may include restlessness, frequent urination, and increased vaginal discharge. The cow’s udder may also begin to swell and fill with milk, and the teats may become full and shiny.
2. Monitor the cow’s behavior.
Cows about to give birth often become more agitated and restless. They may move around more than usual, and may even isolate themselves from the herd. Look for signs of nesting behavior, such as the cow pawing at the ground or gathering hay to lie on.
3. Use a calving calculator.
If you have a record of when the cow was bred, you can use a calving calculator to estimate the due date. This will give you a general timeframe for when the cow is likely to give birth, which will allow you to keep a closer eye on her as she approaches labor.
4. Check the cow’s vulva.
As labor gets closer, the cow’s vulva will become more relaxed and loose. You may notice that the area around the vulva is swollen and puffy, and the cow may have a clear discharge from the vagina.
5. Use a fetal monitor.
If you have access to a fetal monitor, you can use it to listen to the calf’s heartbeat. This will not only help you determine when the calf is likely to be born, but will also give you a good indication of its health.
6. Observe the cow’s appetite and behavior.
In the days leading up to labor, the cow’s appetite may decrease as the calf begins to press on her digestive system. She may also begin to isolate herself from the herd, or may become more vocal.
7. Monitor the cow’s temperature.
A cow’s body temperature will often drop slightly in the hours before labor. By monitoring the cow’s temperature, you can get a good sense of when she is likely to give birth.
By paying close attention to these signs, you’ll be able to determine when a cow is ready to give birth. This knowledge will allow you to make sure she has a safe and comfortable environment in which to deliver her calf, and will also help you identify any potential problems or complications that may arise during the birthing process. With careful monitoring and attention to detail, you can help ensure that your herd stays healthy, happy, and productive for years to come.
