Foster care methods and matters needing attention of piglets

In many farms, in order not to waste resources, according to the litter size of sows, more piglets will be born or because of other circumstances, the remaining piglets that exceed the ability to raise sows will be fed at the place where the number of piglets is small and have the ability to raise sows. This is the method of foster care. Let's take a look at the foster care methods and points for attention of piglets.

1. The principle of foster care

When selecting sows for foster care, comprehensive selection should be made according to the development of sows and the milk volume and nipple size of sows in the past, and piglets adapted to body size should be arranged for foster care. Before foster care, piglets should be kept with their mothers for more than 24 hours. during foster care, the number of nipples of each sow should be checked to make sure that it can breast-feed piglets and then carry out foster care. In general, the number of suckling piglets is 2-3 less than the number of nipples, so that each piglet can drink milk, avoid the phenomenon of predation, and lead to uneven growth.

2. Foster care methods

Foster care should be carried out as soon as possible, as far as possible that each foster piglet can eat enough colostrum, at this time, because in the sow within a week after delivery, the milk contains a lot of immunoglobulin, so that piglets can improve immunity and enhance their physique. With the passage of time, immunoglobulin gradually decreased, so foster care must be as early as possible, no more than 96 hours at the latest. If the piglets born 1-2 days after birth are placed in the litter of post-parturition sows, the piglets with higher body weight must be selected; on the contrary, the piglets born 1-2 days first are farmed in the litter of sows, and the piglets with light weight should be selected so as not to arouse the suspicion of sows and not to breastfeed the piglets. And now when foster care, we must ensure that the litter time of two sows is more than 3 days, otherwise it is easy to lead to foster care failure.

3. Matters needing attention in foster care

Except for foster care, sows have to give birth within three days, but also pay attention to the smell. Pigs are very sensitive to smell, and the way sows and piglets recognize each other is through smell. Therefore, in order to solve this smell problem in foster care, only when sows can not distinguish the smell of piglets can they be regarded as successful. Before foster care, the piglets to be prepared for foster care should be smeared all over the body to prepare the feces of the sows or the placenta after production. After rubbing with the piglets produced by sows for a period of time, the smell can be eliminated. It is necessary to observe carefully after foster care to see whether sows accept foster piglets. If there is a bite phenomenon between piglets and piglets, they should be separated in time and re-foster.
