Feed nutrient technology to increase sow fertility
The level of sow fertility directly affects the farm's production level and economic efficiency. According to statistics, the cost of sow production for 22 weaned piglets per year is 52% less than that of 16 piglets. This technology proposes measures from the perspective of feed nutrition to increase sow fertility and increase economic efficiency. First, the quality of good sows feed. Formulate high-quality, full-priced diets to ensure energy, protein, vitamins, and minerals. It is forbidden to feed moldy and degenerative feed. Moldy corn and soybean meal contain aflatoxins, vomiting toxins, etc., which can easily cause abortion and stillbirth of sows. Second, in accordance with the nutritional needs of sows in stages formulated diet. Nutrients such as protein, vitamins, calcium and phosphorus must be comprehensive in the empty feed to ensure normal estrus. Empty sows should increase feed intake 10 days before breeding to increase sows’ ovulation number and egg quality. Pre-pregnancy must ensure that all kinds of nutrition are complete, but can not be fed with high levels of nutrition, otherwise it will reduce the survival rate of embryos. Feed about 2 kg of pregnant sow material per head per day. Feed intake increased slightly in the second trimester, and about 2.5 kg of pregnant sows were fed per head per day. Young sows and poorly sowed sows are fed more, and partially fatten sows are fed less. Later in pregnancy, the sow’s feed intake was increased, and 2.5-3.5 kg of pregnant sow feed per day was fed. During the lactation period, it is usually stopped on the day of delivery, fed bran water or brackish water, and fed 1.5-2 kg on the second day. After 3 days of delivery, the amount of feed is gradually increased. After 7 days, the amount of feeding should be more than 5 kg. Two to three days before weaning, the amount of feed should be reduced to 1.5-2 kg. Can feed some good green feed. Third, other nutritional technologies that increase sow fertility. The first is the appropriate vitamin supplementation in the sow's diet to increase sows' ovulation rate, conception rate, and milk yield, improve the birth weight and evenness of the piglets, and improve the sow's immunity and reduce limb and foot disease. Occurrence of nutritional diseases. The second is to supplement the probiotics, enhance the digestive function of the breeding sow's intestines, improve the feed utilization and reproduce the sow's production performance. The third is the supplement of functional amino acids, which are essential precursors for the synthesis of many biologically active compounds and play an important role in the growth and development of newborn piglets.
