Causes and solutions of infertility in sows

We often see a lot of sows in pig farms often not in estrus, delayed estrus or not obvious estrus. These problems are also one of the reasons why farmers in many pig farms lose a lot of money year after year. There are many reasons for non-estrus, which have a lot to do with the breeding methods and management problems of breeders. Then Shuai Shuai will tell you what to do if sows are not in estrus.

1. Infertility in sows caused by pathological factors

1. Endometritis

This is a common condition that can directly cause infertility, mostly because of this disease, once suffering from this disease, the uterine mucosa will fester, causing a series of inflammation, even if conceived after estrus, it is also easy to miscarry. We can rinse it with saline and potassium permanganate solution, or use penicillin plus streptomycin to fight cancer.

2. Infertility in sows caused by ovarian cysts.

The imbalance caused by the imbalance of follicle stimulating hormone and luteinizing hormone secretion will enlarge the follicles on both sides of the sow, accumulate a lot of follicular fluid, and then become a luteal cyst, which will most likely cause the sow not to be in estrus. Therefore, when lutein secretion is insufficient, pigs can be injected with HCG to come into estrus.

3. Infertility in sows caused by persistent estrus

The lack of luteinizing hormone makes sows unable to ovulate, which will directly cause them to be infertile or even not in estrus. For this situation, we can inject HCG into our muscles to solve the problem.

2. Infertility in sows caused by improper feeding and management

1. Improper feed

If the feed usually fed to them lacks vitamins and some trace elements needed for life activities, it will cause infertility in sows, and vitamin An and vitamin E, including manganese, will disorder the reproductive function of sows, so it will cause non-estrus and produce symptoms of infertility, so we should improve their feed and feed more feed containing vitamins and carotenes. More trace elements can also be added to the feed so that the nutrition of sows is more complete and the estrus rate is higher, and refined cod liver oil can also be used in the feed.

2. Improper management

The environment of some farms is very poor, not ventilated and airtight, sealed to death, resulting in a very poor environment, the mood of pigs is affected, in addition, sows and boars are generally separated, which will lead to long-term lack of sexual stimulation in sows, which leads to infertility. In addition, sows can be stimulated to estrus through hunger, and drugs can also be used.

The above are the causes and solutions of sow infertility. Have you learned it? If people have the above symptoms, they should be treated and managed in time. I hope this article can help you.
