A cow typically comes into heat 30 to 60 days after calving. This period can be as short as 20 days or as long as 80 days, depending on various factors. However, there are certain signs that indicate whether a cow is in heat again after calving. Let’s discuss these signs:

1. Increased Movement: Cows in heat tend to be more active and restless than usual.
2. Behavior: A cow in heat may show increased interest in other cows. It will be ready to mount or be mounted by other cows.
3. Urination: Frequent urination is often observed, which is unusual compared to the cow’s normal behavior.
4. Vaginal Discharge: A common sign of estrus is a clear, stringy mucus discharge from the vulva.
5. Change in Vulva: The vulva may appear swollen and moist during heat, which is also a common sign.
