Currently, around 80% of sows give birth at night, which makes it difficult for farmers to monitor and assist them in time. This often leads to piglet deaths due to lack of immediate care, significantly affecting the economic efficiency of pig farming. To address this issue, a new technique has been developed in recent years that encourages sows to farrow during the day.
The method involves administering 1 to 2 milliliters of cloprostenol into the sow's cervical muscles approximately 8 to 9 hours before the expected farrowing, usually on day 112 or 113 of pregnancy. With this approach, 98.2% of sows gave birth during the daytime the next day. According to trial results, this technique also improved the piglet survival rate from 95% to 98%, making it a valuable innovation for modern swine production.
Cloprostenol is known for its ability to dissolve the corpus luteum in pigs, cattle, sheep, and horses. By doing so, it reduces progesterone levels, which helps trigger labor. It also stimulates the uterine muscles, relaxes the cervix, and ensures smoother and more controlled birthing. This not only shortens the farrowing process by about 30 minutes but also promotes better removal of the placenta, easier lochia discharge, and faster uterine recovery.
Additionally, cloprostenol has shown effectiveness in treating conditions such as luteinizing cysts, infertility, and retained placentas. It can also help reduce the occurrence of postpartum complications like mastitis, metritis, and milk deficiency. For farmers looking to improve both productivity and animal welfare, trying this technique could be a smart and beneficial choice.
