Frequently Asked Questions for Newborn Sows

Pig is one of the largest domestic animals in China. The annual consumption of pork in our country is the largest among meat products, and pig farming is very common now. When raising pigs, sow production is very critical, which affects whether it can be raised continuously and efficiently. And some first-born sows often encounter a lot of problems when giving birth. The following editor brings you several common problems of first-born sows, let's have a look!

1. Eat less during pregnancy

Many people will have a problem when raising pigs, that is, when some first-born sows enter the pregnancy, the food intake will be significantly lower. In this way, fetal pigs will be undernourished. The reason for less food intake during pregnancy is mainly due to the weak physique of some sows, so they can not grab food in the herd, resulting in a reduction in food intake. In view of this phenomenon, we should be divided into groups reasonably, or raised separately according to the strength or weakness, to ensure the food intake of each pregnant sow and improve the quality of the young pigs.

2. Eat less during lactation

Eating less during lactation is also a common problem in first-born sows. Because sows will have serious weightlessness after giving birth, if food intake is reduced again, then lactation must be insufficient. If piglets do not have enough breast milk, there will be a series of problems, which will seriously affect the growth of piglets. Therefore, in order to improve the food intake of sows in lactation, we should improve the nutrition level of feed. Enhance the quality of feed and improve the growth environment of sows.

3. Poor quality of piglets

In general, the growth ability of piglets delivered by newborn sows is slightly lower than that of piglets delivered by sows. The piglets of newborn sows are lighter in weight and lower in vitality, so they are easy to become weak piglets. The main reason for this is that the first-born sows have a small uterine volume and eat less during pregnancy. Only small and weak piglets can be raised together, and sufficient sows should be ensured to prevent excessive death of weak piglets and affect the efficiency of breeding.

4. The interval of weaning estrus is long.

After the first sow is weaned, there will be a lot of problems. One of the most common is that the interval between the second estrus is very long, even if it can be normal estrus, the litter size will be affected and reduced. It is mainly due to the lack of food intake of sows after weaning, and this problem will occur if the physique does not recover as soon as possible. Therefore, we should not only improve the nutrition level of feed during the lactation period of sows, but also appropriately reduce the burden of sows. If the lactation of sows is insufficient, we should reasonably regulate the number of piglets and do a good job of piglet foster care.
