Common misunderstandings in sow breeding

Raising pigs is the most common breeding project in our country, if you want to ensure continuous and efficient breeding when raising pigs. Then the feeding work of sows is very important, raising sows to improve the reproductive performance of sows can ensure the healthy and stable development of pigs. However, many pig farms have a lot of misunderstandings when raising sows. So what are the specific ones? The following editor will give you a brief introduction to the common misunderstandings of sow feeding, let's take a look!

1. Abuse of mildew remover

Feed is very important to the growth of sows, so the quality of feed needs our attention. If it is fed with moldy feed, it will have a great impact on the reproductive performance of sows. As a result, many bad enterprises will advertise the disadvantages of moldy feed in order to promote the mildew remover they produce. It causes pig farmers to use a lot of mildew remover for a long time. Whether mildew remover can effectively decompose mycotoxin needs further research, so it is very undesirable to abuse mildew remover.

2. Abuse of estrus hormone

Although the sow is properly injected with aphrodisiac hormone, it has obvious effect. However, most sows will only be in estrus and will not ovulate, which will seriously affect the success rate of mating. And although some sows seem to have been successfully mated on the surface, the empty rate is also very high. This leads to a decline in the litter birth rate of sows, and in serious cases, there will be false pregnancy and no embryo implantation. If long-term use of aphrodisiac hormones, then it is very easy to lead to sow ovarian function decline or even atrophy. Cause delayed estrus, non-estrus and other reproductive obstacles.

3. Abuse of oxytocin

At present, many pig farms are using oxytocin, mainly in order to shorten the labor process of sows and advance the excretion time of placenta. However, if a large amount of oxytocin is used for a long time, it will also do great harm to sows. For example, it may lead to premature rupture of the umbilical cord of piglets, resulting in the death of piglets in the birth canal. It may also lead to rupture of amniotic fluid and dystocia in sows. And the sow colostrum secretion is low, the piglet survival rate is low. At the same time, it will also have a great impact on the endocrine system of sows, so we must use oxytocin rationally. In addition, we should also pay attention to the use of oxytocin.

4. Endometritis

Endometritis is a major cause of reproductive disorders in sows. At the same time, it is also the main reason for sows to return to love and give birth to weak babies. Sows with constipation or thought to destroy the environment in the womb can lead to an increase in the number of weak fetuses, resulting in hysteritis. In general, the main performance is that the cervix of the sow dilates when it is in estrus. Prone to purulent blood or yellow fluid, and constantly excreted, resulting in sows not in estrus or not worthy of breeding, and so on. At this time, we should pay attention to the rational use of progesterone to avoid premature stillbirth.
