What are the characteristic signs of a pseudopregnant sow?
In the process of raising sows, pseudopregnancy is often encountered. Once pseudopregnancy occurs in a sow, the loss to the farm is very large. So if you want to reduce breeding costs and increase the farmer's income, you have to learn to distinguish whether a sow is truly pregnant. So what are the characteristics of a pseudopregnant sow? Farmers can judge from the following three aspects.
1. Appetite
After a sow conceives, its appetite increases greatly. If you find that a sow on the farm suddenly has a greatly increased appetite and eats faster and more than other sows, then it shows that the sow is already pregnant. But if the sow does not seem hurried when eating feed, but eats slowly, and its food intake is not much different from before, then it can basically be judged that this is pseudopregnancy.
2. Preferences
Compared with non-pregnant sows, pregnant sows prefer to sleep quietly rather than walk around. If a sow shows symptoms of being quiet and liking to lie down and rest at every opportunity, then the probability of pregnancy is very high. On the contrary, if the sow still walks around after eating, then it clearly does not match the characteristics of a pregnant sow.
3. Boar
Within 1 month after a sow is mated, a boar can be used for testing. If the sow has no reaction, the probability of pregnancy is relatively high. If the sow appears unusually excited and shows signs of estrus, then it can be determined that this sow is indeed not pregnant. The farmer can then prepare this sow for the next round of mating so that it can conceive as soon as possible.
In the process of raising sows, farmers must master the methods for judging whether a sow is pregnant, detect pseudopregnant sows as early as possible, and re-mate them in time. In addition, sows have individual differences, and the characteristics they show may differ, so when a farmer is relatively suspicious about a certain sow, advanced technology can also be used to assist judgment, so as to avoid missing the sow's health care period.
