Regarding sows’ lack of estrus and retarded estrus, we have visited rural areas in Yitong County, Jilin Province, Changtu County, Liaoning Province, Kaiyuan City, Xinmin City and other places. After visiting many pig farmers, we found that there are many cases of sows not in estrus. Nearly all sow farmers have encountered this phenomenon, especially well-bred sows that often show delayed estrus or no estrus. These sows are not in estrus mainly in the following three situations: first, sows of appropriate age are not in estrus; second, primiparous sows are not in estrus; third, multiparous sows are not in estrus.
Shengda experts suggest: For sows with delayed estrus, different measures can be taken according to different situations.
Nutritional control: Sows with weak body condition should be strengthened in nutrition, short-term optimal feeding, and supplementary feeding of high-quality green feed, so that they can reach fat as soon as possible. For over-fat sows, feed restriction should be implemented, and they should exercise more and feed less until Restore physical condition for use.
Management measures: Adjust the sows' pens. Boar stimulation. Overfat sows were starved and their feed was halved.
Traditional Chinese medicine conditioning: For sows that are not in estrus or have retarded estrus, add the sow's vitality to the mix to treat the sub-health of the sow, restore the sow's health, and promote estrus and follicle maturation and ovulation within a day.

Consider genetic factors: Take various measures to prevent sows from showing their first signs of life at ~months of age. Those in estrus may be due to genetic reasons or other reasons and should be eliminated in time to avoid further losses.
