Induction of estrus In the production practice, the induction of ovulation in normal estrus in weaned sows can shorten the reproductive cycle of sows and improve the utilization efficiency of breeding pigs. Commonly used methods include boar induction, merging and circling, strengthening exercise, breast massage, and use of exogenous hormones (pregnancy horse serum gonadotropin, human chorionic gonadotropin, etc.). Early weaning in the production of sows, sows weaned 60 days per year can produce 1.8 litters, 45 days weaned sows can produce 2 litters per year, 28 days weaned sows can produce more than 2.2 litters per year. Generally factory-intensive, intensified pig farms, piglets can be weaned at 4 to 5 weeks of age, and farmers can raise pigs at the age of 7 weeks. Fostering foster fostering refers to the practice of fostering prolific or non-eating piglets to sows with fewer calves when a certain number of sows give birth at the same time in the pig farm. It is one of the effective measures to increase the survival rate of the pigs. Some gilts were bred and mated as soon as possible, shortening the interval between the sows in this section.
