Scientific management of sows before mating
Feeding and management of sows before mating The sows generally have two estruss throughout the lactation period: the first estrus is 27 days after childbirth, and the matings are not pregnant during this period. The second estrus occurs 23 to 32 days after childbirth, when the sow is at the peak of lactation, and the estrus symptoms are not obvious and it is not easy to be found. Later, due to the influence of lactation, it usually takes 4 to 12 days after weaning to reach the sow before the breeding period. Due to the high nutritional consumption of sows in the lactation period, most sows suffer from poor phlegm and weak constitutions. Therefore, it is necessary to strengthen feeding and management so as to restore physique as soon as possible. In addition, sows should stop lactation as soon as possible to prevent mastitis.
Feeding and management before mating of gilts and gilts before mating can be performed in the short period of time before mating of gilts and gilts, which can increase the number of ovulation by about 2 pieces. The specific approach: the primiparous sows are treated 3 to 4 days after weaning and treated by the rearing and management methods of the sows, and they are given excellent feed until the end of breeding; the gilts should be abundantly bred before the 70 kg weight, 71 After the weight of kilograms should be restricted to feeding, so as not to affect the estrus breeding and breeding. However, 11 to 14 days before breeding until the end of breeding, short-term excellent feeding should be performed, and 22.5 kg of mixture should be fed daily.
