In order to increase the embryo implantation rate of pregnant sows and also to increase the feed intake of sows during lactation by controlling the body condition of pregnant sows, we adopted a feeding restriction mode for pregnant sows. The design of pregnant sow material is actually a difficult point. On the one hand, the nutritional needs of the sow during the first, second and later stages of pregnancy are different. The sow’s body condition after re-gestation during nutrient consumption during breast-feeding is different. Standard feeding of pregnant sows is clearly inappropriate. Due to practical operation restrictions, different feeding amounts are generally used to meet the nutritional needs of pregnant sows in different nutritional stages. On the other hand, there are misunderstandings in feeders' feeding patterns for pregnant sows that restrict feeding. The damage to the sow's subsequent reproductive performance caused by improper feed restriction has become more and more serious, which should cause the pig’s note. The degree of restriction of sows in pregnancy is generally judged by the sow's body condition score. In the traditional 5-point scoring system, a 3-point body condition was considered appropriate. The current concern of the pig industry is the new understanding of improper feed restriction. Improper food restriction may not be represented by body condition indicators. It may be due to insufficient deposition of body fat and reflected by the thickness of back fat. It may also be possible. Because nutrient formulas and nutrient concentrations do not take into account the nutritional needs of pregnant sows in the case of restricted feeding, nutrients associated with normal expression of reproductive performance and immune function are not adequately replenished. Because it is not necessary for the breeder to ignore the thickness of the backfat, it is easy for the breeder and nutritionist to have the harm caused by the shortage of special nutrients in the body during the gestation period of the sow. The need to reconsider. Insufficient supply of protein and special nutrients in the sow during pregnancy, in addition to affecting the development of the fetus, is currently particularly concerned about the nutritional support needed for the sow's immune response. In actual production, the sows are forced to bear the burden of immature swine immunization. Prenatal and prenatal antenatal vaccination increases the number and types of vaccines. Feeders and nutritionists do not pay enough attention to the nutritional support needed for the sow’s immune response. This may be one of the reasons for the decline in the overall health of the herd. In addition, the sows fed during the term of pregnancy, due to the small amount of feed, eaten restaurants have insufficient filling of the gastrointestinal tract for a long period of time. On the one hand, it is not conducive to peristalsis of the intestine and is prone to sow constipation. On the other hand, Affecting the increase in feed intake during lactation of sows, special attention should be paid to the supply of fibrous feed during the sow pregnancy feed formulation. Most traditional medicinal mushrooms such as Ganoderma lucidum, shiitake mushrooms and Maitake mushrooms have shown a common characteristic of enhancing immune function by stimulating cell-mediated immunity. Simply put, members of the mushroom family seem to "turn on" cells in the immune system, known as T cells. They all have their anti-cancer properties. Three different anticancer drugs that Japanese researchers have extracted from mushrooms have been approved by the Japanese Ministry of Health and Welfare.
