Sow non-estrus treatment trick, remember to collect after reading!

Recently, some farmers often ask sows about non-estrus, saying that sows seem to be able to eat and sleep, and that they are very healthy, but they do not know what is going on. In fact, it is very simple. Sows without estrus are mainly caused by uterine problems, which is not obvious. Today, we will explain to farmers how to deal with sows without estrus for farmers' reference.

1, the first sows are not in estrus, the main reason is that the sows lose too much weight during lactation, especially in some small pig farms, the first sows without estrus account for 60% of the total, and some of them are eliminated without timely treatment. This kind of sow must strengthen nutrition, exercise more and promote gastrointestinal absorption.

2, if the sow that gives birth to too many babies is not in estrus, it should be treated according to different reasons, the uterine inflammation should be antibacterial and anti-inflammatory, the sow is too fat and too thin, the feed should be adjusted, and if the reason can not be seen, it can be treated by changing barracks, boar stimulation and other methods.

3, reserve sows do not have estrus, need to change the barn, use boars to stimulate sows, less feed to stimulate estrus, because sows have not been produced, so inflammation is not the main cause. Can feed sows with green feed, let sows supplement vitamins and so on.

4, for the above three types of sows without estrus and still not estrus after treatment, can be stimulated with estrus drugs, the effective rate can reach 50%. Don't use aphrodisiac directly before treatment.

5. it is normal for sows not to be in estrus when it is cold in winter. it is necessary to improve the environment first. do not use estrus powder or estrus powder unless you have to. If western medicine is hormone pregnancy horse serum, if it is traditional Chinese medicine, it is epimedium, actinomycete, aconite, etc., all of which may have an impact on the physiological function of sows.

6, if the sows that have not been in estrus for a long time should immediately breed and breed again at an interval of 12 hours, the effect is very obvious. boars are used to stimulate estrus, twice a day, the libido is exuberant and foaming boars and sows are put together for about 20 minutes at a time, and then drive the boars away as far away as possible.

7. Under normal circumstances, if the weaning sow is still not in estrus or unworthy after three estrous cycles, and the reserve sow is still not in estrus or infertile at the age of one year, consideration should be given to timely elimination to avoid ineffective breeding.
