At present, around 80% of sows give birth at night, which makes it difficult for farmers to monitor and assist them. This lack of timely care often leads to high rates of piglet mortality, significantly affecting the economic efficiency of pig farming. To address this issue, a new technique has emerged in recent years—encouraging sows to farrow during the day.
This method involves administering 1 to 2 milliliters of cloprostenol into the sow’s cervical muscles approximately 1 to 2 days before farrowing, specifically between 8 and 9 a.m. when the sow is around 112 to 113 days pregnant. As a result, over 98.2% of sows gave birth during the daytime the following day. According to trial data, this approach also increased the piglet survival rate from 95% to 98%, showing promising results.
Cloprostenol works by dissolving the corpus luteum in pigs, cattle, sheep, and horses. It reduces progesterone levels in the blood, which helps trigger labor. Additionally, it stimulates the uterine muscles, relaxes the cervix, and enables smoother delivery according to a scheduled time. This not only shortens the birthing process by about 30 minutes but also promotes faster removal of the placenta, lochia discharge, and uterine recovery.
Moreover, cloprostenol has proven effective in treating conditions such as luteinizing cysts, infertility, retained placentas, and other reproductive issues. It can also help reduce postpartum complications like pain, mastitis, metritis, and milk deficiency. For farmers looking to improve both sow health and piglet survival, this treatment is worth considering. With its multiple benefits and high success rate, it's becoming an increasingly popular choice in modern swine production.
