Management during pregnancy is crucial for cows, and it becomes even more critical when the calving is expected during the summer. This is because summer calving can more easily lead to diseases. Let's learn about the considerations for summer calving for cows.
Considerations for Summer Calving for Cows:
-
Disease Prevention: After calving, retained placenta is a common occurrence, which is a major cause of septicemia and uterine inflammation. If the placenta does not come out within about two weeks, it needs to be manually handled. Inject a solution of 10% sodium chloride (1500) to dehydrate the placenta, then inject 1 gram of oxytetracycline dissolved in 250 ml of distilled water into the uterus to prevent decay. It will shed within a few days. Injecting sodium chloride before birth facilitates detachment. Afterwards, administer some anti-inflammatory drugs until the lochia is cleared.
-
Uterine Involution: During pregnancy, the uterus enlarges, pressing against nearby organs. After calving, it is essential to ensure that the uterus returns to its normal position to avoid adverse effects on other organs and future pregnancies. Feeding a decoction of motherwort for several days post-calving can aid in uterine involution and promote recovery.
-
Nutritional Needs: Calving consumes a considerable amount of energy, so feed bran or other feeds cooked into a soup, along with warm water mixed with brown sugar. This provides essential nutrients. The first half month after calving is the recovery period. During this time, primarily feed dried grass, provide small amounts frequently, encourage drinking warm water, and gradually increase concentrate feed. After one week, exposure to sunlight is beneficial. Avoid feeding roughage.
-
Postpartum Care: Immediately after birth, clear the mucus from the mouth and nose, and dry the body with a cloth. Provide soft dry hay for the cow to rest on, ensuring the surrounding environment is dry and clean. Use a dry cloth to wipe off any mucus on the calf's body; avoid washing temporarily. About a week after calving, if the recovery is good, bathe the cow. Then change the bedding. Normal management can resume once the recovery period ends.
Summer calving is detrimental to the health of cows. However, if faced with this situation, attention must be paid to post-calving care to maintain the health of both the cow and calf. In summary, the key considerations for summer calving include cleanliness, disinfection, and prompt recovery. Preventing postpartum diseases and providing adequate nutrition are essential.

Summer calving presents unique challenges for dairy farmers, as the heat and humidity can increase the risk of heat stress for both cows and calves. It's crucial to provide adequate shade, ventilation, and access to clean, cool water to help alleviate heat stress during the summer months. Additionally, monitoring for signs of heat stress, such as increased respiration rate and decreased feed intake, is essential for early intervention.
Furthermore, proper fly control measures should be implemented to prevent fly-borne diseases and discomfort for the animals. This can include using fly traps, applying insecticides, and maintaining clean barn conditions to minimize fly breeding sites.
Frequently Asked Questions (FAQs):
-
Q: How long is the recovery period for cows after summer calving?
-
A: The recovery period for cows after summer calving typically lasts around 2-3 weeks. During this time, it's essential to provide proper nutrition, monitor for any signs of postpartum complications, and ensure a clean and comfortable environment for the cow.
-
Q: What are some signs of heat stress in calves?
-
A: Signs of heat stress in calves include rapid breathing, panting, drooling, lethargy, and decreased feed intake. It's important to provide shade, proper ventilation, and access to cool water to help alleviate heat stress in calves during the summer.
-
Q: How can I prevent fly infestations in the barn during the summer?
-
A: To prevent fly infestations, implement fly control measures such as using fly traps, applying insecticides, and maintaining clean barn conditions. Regular manure removal and proper waste management can help minimize fly breeding sites.
