According to the growth and development of embryos, embryos grow fastest in the later period of sow pregnancy. So we often increase the energy and protein concentration in feed during the later stage of sow's sow (feed from pregnant material or material in late pregnancy). Increase the amount of sow feeding to increase the birth weight of piglets. This is what we usually call "craving." So is this so-called "trucking" right? How is rigging right? Why do you want to attack In simple terms, slicing is to increase the weight and vitality of piglets and the quality of sow colostrum. Most pig farmers know that sows are pursuing fetuses in the later stages of pregnancy. However, what is going to be attacked may not be very clear. In addition to increasing the birth weight of piglets, the second trimester of pregnancy needs to consider two important indicators to increase the vitality of newborn piglets and the quality of colostrum. It is also necessary to consider the effects of the attack on childbirth and breastfeeding at the later stage. The vitality of newborn piglets is more important than the birth weight of piglets. The friends with pig-raising experience know that the birth weight of piglets five years ago was not very large, and about 1.2 kg was common. The vitality of the piglets is very strong. Once they are born, they know how to find milk immediately. As long as the sow has good milk, the growth rate is not slow and the survival rate is high. The current birth weight of piglets is larger than before and can generally reach about 1.5 kilograms. However, we found that more and more newborn piglets are very large, but they show pale skin, are weak and weak, and do not understand how to look for milk. The phenomenon of poor vitality such as robbing milk and inability. Even if the birth weight is heavy, his survival rate and growth rate will be greatly affected. Under the same weight, only a vigorous individual can eat enough colostrum, and only if the piglet has a strong vitality can stimulate the sow to produce more colostrum and lay a solid foundation for its healthy and rapid growth. Correct reticle method Studies have shown that sows' mammary glands are in high-speed development from 75 days to 95 days of pregnancy, and now we have a high energy and protein concentration in our lactation feeds or during pregnancy. If craving starts within 85 days, it will lead to too much fat deposition in the sow's breast, leading to insufficient milk during lactation. And one month before birth, a burping begins, and it is very likely that the piglets are too big, causing difficult labor and stagnation during childbirth. After a lot of practice has proved that it is reasonable to start sipping a fetus at 95 days of pregnancy. In addition to requiring a large amount of energy and protein for the fetus to grow rapidly, the sow needs a large amount of nutrient energy to protect the normal development of the fetus and improve the vitality of the newborn piglet and the quality of the colostrum. Mammalian fetus nutrition is provided through the maternal placenta, and the function of the placenta is directly related to the normal development and growth of the fetus in the womb. Nutritional energy in Pelevi has an important role in the growth and function maintenance of sow placenta. It has been reported that placenta efficiency is lower in the first child, and second to fourth births tend to increase in childbirth and begin to decline in the fifth child. Therefore, for the first parity sows and more than six litters of sows need to supplement nutritional energy to promote the growth of the placenta, delay the decline in placental function. In the later stages of pregnancy, the rapid growth of the fetus causes pregnancy stress that consumes a large amount of nutrient energy to fight stress. Especially in hot summer days, in order to disperse the peripheral telangiectasia and increase blood flow of the sow, the corresponding supply of nutrients to the fetus through the placental capillaries falls, requiring additional nutritional supplements.
