Problems solved by technology

[0002] In recent years, my country's pig industry has developed very rapidly. The breeding of pregnant sows is the key to the economic benefits of pig farmers. Pregnant sows can’t keep up with nutrition, which makes the embryo unable to develop normally, resulting in low birth weight of piglets. It is due to improper feeding that makes pregnant sows overweight, excessive accumulation of fat tissue in the abdominal cavity oppresses the uterus, and affects the development of fetal pigs. The weak and small piglets are produced, resulting in dystocia, which not only loses the fetus, but also causes great damage to the sow's body, causing serious economic losses to the pig farm; therefore, inventing a scientific and reasonable breeding method for pregnant sows can be effective Increase the economic benefits of pig farmers

Abstract

The invention discloses a pregnant sow feeding method. The pregnant sow feeding method includes the steps: (1) a stage from the beginning of pregnancy to the 30-th day of pregnancy; (2) a stage from the 31-th to the 90-th day of pregnancy; and (3) a stage from the 91-th of pregnancy to a delivery day; and in the three stages, different feeding methods are used for feeding the pregnant sows with pregnant sow fodder. According to the physiological characteristics of the pregnant sows, the pregnant sows are feed with different amounts of pregnant sow fodder in different stages; and the pregnant sow feeding method can meet the nutriment demand of pregnant sow breeding and the nutriment demand of fetal porcine growth and development, can lower the possibility of dystocia, weak small piglets, and dead piglets, and can significantly improve the production efficiency of the pregnant sows.
