What should I do if the sow does not let the boar breed? Many pig farmers should have encountered this problem. One of the biggest uses of sows is mating and giving birth to piglets. If you have estrus, it is more difficult to give birth to piglets. So, what is the reason for the sow's estrus? Take a pig farm as an example to see if your farm has the same problem. The farm is in an extended stage and has a large number of gilts; however, the gilts are already very old, but half of them are not bred, and we start looking for reasons. The staff’s work was normal; after a few days, the estrus situation did not improve. However, in this process, a special phenomenon was discovered; some sows looked at the estrus, and the vulva began to become red and swollen, but after a day passed, it did not reach the level of cultivating, and the redness and swelling gradually subsided. It has passed. This situation is often related to nutrition, mostly caused by inadequate nutrition. The daily feeding amount is supplied according to the standard, and the quality of the feed is no problem. What is the reason? Two problems were found during the observation of the feeding process, one was the quality of the feed, and the other was the problem of large-circle feeding. Although it was fed in standard quantities, because it was in the winter and in the northeast, the corn did not dry out, the water inside was too large, and the water was relatively low in nutrients; later we measured that the water could reach 25%. Such corn is equivalent to 90% of normal corn, the same amount of feeding, while the nutrition of pigs is reduced by about 10%, and in the long run, there will be nutritional deficiencies. The second problem is feeding in large circles. The amount of material added to each column is the total amount, while the strength of the pig is different, the speed of feeding is different, and the feed in the stomach is different. Still estrus, but most of them will suffer from malnutrition. Summarized as follows: One is the strength and weakness of the group, the second is to increase the original feed based on 10%, or use low moisture corn. After this adjustment, the estrus condition of the sow began to improve after half a month, and finally most of the sows were properly matched to give birth. Sows are not estrus in many farms. Sows have estrus symptoms but they are not suitable for breeding. It is even more difficult. The above are just examples of individual farms. The specific reasons for each pig farmer are to be combined with actual factors or experts to analyze!
