The method of multiparity and high yield in sows

The main purpose of raising sows is to produce piglets. In order to increase the production of piglets and achieve the purpose of improving economic benefits, we usually use a variety of ways to reasonably increase the production of sows. After a long period of research and summary, there are many ways to improve sow production, so today the editor mainly introduces several commonly used methods here, hoping to be helpful to you.

1. Select high-quality breeding pigs

If sows want to have multiple births and high yield, then the choice of breeding pigs is the most basic condition. We can never choose those poor sows whose cost is high and difficult to manage and raise. At the same time, the annual litter yield is still low. So we have to choose strong, high litter yield and other excellent breeds to raise, then we need to be fully prepared. It is necessary to study the past generations of production and feeding of selected pigs as well as the market situation to conduct a comprehensive analysis, and finally select the best quality breeding pigs, so that the litter yield can be guaranteed to a certain extent.

2. Strengthen feeding and management.

The quality of sow breeding will affect the yield and quality of piglets, so we must strengthen the feeding and management of sows. First of all, in the early stage of pregnancy, we need to grasp the nutrition of sows and provide them with adequate protein, vitamins and other trace elements. Secondly, in the second trimester of pregnancy, there is no need to have too many reasons, just provide sufficient coarse feed. Otherwise, the fertility of sows will be affected by excess nutrition, and then the postpartum appetite of sows is relatively small, so we should first feed some nutritious food, and then slowly increase the amount of coarse food. at the same time, in normal feeding, we should make reasonable ingredients in strict accordance with the nutritional needs of sows.

3. Select timely mating

The breeding time of sows must be arranged reasonably, otherwise it will do great harm to the yield of piglets and the body of sows. If, according to the normal process, we have to wait until the piglets are weaned, that is, about one and a half months after weaning, and mating is carried out about a day after sows are in estrus, the success of mating will be higher at this time, and there will be no abortion, but sometimes the sow will be in estrus later. So we can give the right amount of estrus medicine about a day after weaning, which can make the sows in estrus and then mate. Finally, the best time for sows to breed is from April to May and from September to October every year, so as to avoid colds and heatstroke.

4. Select high-quality boars

The selection of high-quality breeding boars is also a relatively basic condition for the success rate of breeding and the birth rate. if the breeding boars are not selected well, then there will not be many piglets, and the quality will not be good at the same time. We should choose strong, high-quality sperm, in the adaptation period, not frequent breeding boars for breeding, in order to improve the productivity of sows.

5. Take measures to protect the fetus.

Sows are very prone to miscarriage 10 to 15 days after successful breeding and about 20 days before production, so we should be very careful in these two periods and take safety measures to protect the fetus. First of all, we can feed more high-quality feed that contains more protein, vitamins and other nutrients, and the second is to do a good job in daily management. Clean up all the items in the pigsty that can hurt the sows, and finally take epidemic prevention measures, so that you can effectively protect the fetus.

6. Control the fat of sows

In order to increase the litter yield of sows, the fat management of sows is also very important. It is best to keep the sows in a state that is not fat or thin. This is the best state of sows. If the sows are too fat, then it is very easy to have slippery fetuses and low litter yield, and if they are too thin and not easy to conceive, it is necessary to maintain the fat of sows. In the normal process of feeding and management, according to the growth of sows. Scientific feeding and calcium supplement management of sows, otherwise it is easy to cause prenatal or postpartum paralysis of sows.
