In recent years, reproductive disorders in sows have been a major problem in the pig industry. Many sows often experience estrus, infertility, miscarriage, stillbirths, and poor births. Through years of clinical experience, the causes of the morbidity and treatment methods are summarized as follows:
First, suffering from reproductive disorders
At present, more than 30 diseases related to porcine reproductive disorders have been confirmed. The occurrence of blue ear disease, circovirus infection, swine fever, pseudorabies and eperythrozoonosis has a great influence on sow reproduction, especially at the beginning. The sows are most at risk and can cause 40%-70% of the sows to have miscarriage, stillbirths, and weak litters. The born piglets are thin, have low survival, and have high mortality.
Prevention: to ensure the correct use of infectious disease vaccines, regular use of Astragalus polysaccharides to improve pig immunity, can play a good preventive effect.
Second, the mycotoxin in the feed is exceeding the standard
In addition to causing acute poisoning and death of pigs, mycotoxins also cause chronic diseases such as reduced reproductive performance.
Prevention: In order to reduce the mycotoxins in the feed, the storage environment should be kept dry and hygienic when storing the feed. In addition, it is better to add de-mold agent to the feed.
Third, endometritis or vaginitis
When mating with sows, vaginal or uterine mucous membranes are caused to become inflamed due to irregular operation.
Treatment: Add a certain course of antibiotics to the feed.
Fourth, the individual reasons
Sows are too fat or too thin, resulting in reduced reproductive performance.
Treatment: To reduce the amount of fat fed, to feed some crude protein containing low protein, to ensure normal body condition; Too thin the first worms to stomach, increase the amount of feed, feed more protein-containing feed and green Juice feed, double the use of multivitamins to supplement the nutrients needed to make it balanced.
