Adding the right amount of vitamins in sow diets can eliminate the adverse effects caused by vitamin deficiency. Therefore, it is necessary to formulate the best recommended vitamin levels in actual production in order to fully realize the animal genetic potential and protect the body's health. Economic benefits. Breeding period
B vitamins are important coenzymes in the metabolic process of biochemical reactions. For example, biotin can reduce the interval from the weaning to the estrus of sows by participating in energy metabolism. It can also stimulate estrogen production and reduce the rate of non-estrus. Tests have shown that vitamins increase litter size by affecting the reproductive cycle, and that piglets supplement the optimal dose of vitamin B at weaning can increase piglet growth.
Ovulation and fertilization
After the sow has reached the stage of development, the estrus rate can be as high as 20%. Sows supplemented with 7.5 mg of vitamin B2 (riboflavin) per day can reduce the rate of non-estrus. Especially in the tropics, vitamin C supplementation can effectively prevent summer infertility. In addition, supplementation with biotin can increase the fertility rate of sows, especially for sows that have longer intervals from weaning to estrus. Vitamin E acts primarily as an antioxidant to maintain the integrity of the cell membrane and prevent cell damage. Due to the high content of unsaturated fatty acids in sow diets, vitamin E needs to be added.
Early pregnancy
Folic acid can affect the survival of embryos and fetuses, and increasing the amount of folic acid can increase litter size. Folic acid is widely present in common feeds and has a high utilization rate. Experiments have shown that folic acid supplementation has a significant effect on litter size in sows compared to gilts and second sows. This may be due to the higher rate of ovulation in older animals and the resulting death of embryos. The possibility is greater. Its mechanism of action may be due to its involvement in the regulation of embryonic Leptin receptors and endometrial tissue. It not only affects the metabolic rate of animals and feed intake, but also plays an important role in controlling reproduction.
Fetal growth period
Biotin plays an important role in embryo implantation in the uterine wall. The placenta is a filter between the maternal and fetal blood systems. It can select the type and level of nutrients that pass through the placental barrier. The fetal growth after implantation will depend mainly on the placenta for this filtering action to obtain nutrients. In late pregnancy, the fetus grows very quickly, so the demand for vitamins also rapidly increases. The vitamins supplied by the mother alone cannot meet the needs of fetal growth. The lack of vitamins in the fetus can cause malformation or death. B vitamins are generally not stored in the mother's body and the fetus. They mainly act on the enzyme system. The fetus obtains vitamins through breast milk. The amount of vitamin B is related to the amount of vitamin B in the sow's diet. In late pregnancy, the uterine muscle tension is also considered in order to expand the uterus and accommodate the increased need for the fetus.
