Breeding pigs are responsible for the task of breeding replacement pigs. While the reserve pigs are still in the growth stage, they have to shoulder the double responsibility of growth and reproduction. Therefore, keeping the reserve pigs in accordance with the traditional nutritional requirements of the pigs for feeding animals will cause the pigs to be replaced. Nutritional overdraft. To completely solve these problems, it is necessary to provide specialized nutrition for the physiological characteristics of the reserve pigs. 1. Rich in vitamins The vitamins in the reserve pig feed must be supplied according to the requirements of the breeding pig. Adequate vitamins can promote the development of reproductive organs, normal estrus, increase the number of ovulation, and increase the rate of pregnancy. It is recommended to use Roche Multidimensional or BASF Multidimensional, and then according to the amount of lack of Kazakhstan complement Kazakhstan, lack how much to add. 2. A sufficient amount of calcium and phosphorus The skeletal development of tall lean pigs is relatively late. During the later stages of gilt development and breeding, it is necessary to provide diets with higher levels of calcium and phosphorus to increase mineral deposition. The quantity of calcium and phosphorus needed to be supplied in accordance with the requirements of breeding pigs, so that the reserve pigs have strong limbs. The available phosphorus requirement is not less than 0.36%, calcium is not less than 0.75%, and calcium is not less than 0.7% when phytase is added to feed. 3. Supplemental organic chromium, selenium, cobalt Organic Chromium has a growth-promoting effect on pigs and can improve the carcass quality of pigs and effectively improve the body's immune level and stress resistance. The main role of selenium is to increase litter size, reduce piglet mortality before and after weaning, and increase sows Milk production, improve immune capacity; Cobalt is the main element in the synthesis of VB12 in pigs, pigs generally do not lack, so the feed is generally not added, but boar supplementation of cobalt can improve boar reproductive capacity. 4. Balanced and abundant amino acids and high energy Modern breeding pigs are all high-lean cultivars and require high-energy and abundant and balanced amino acids to meet the needs of reserve growth and development and lay the foundation for future reproduction. 5. Use of monomeric amino acids should be as small as possible in lactating sows Amino acids should mainly be provided by animal and Plant Protein feeds. If a large number of amino acids are added, their effects are often counterproductive. While satisfying the limiting amino acids such as lysine, methionine, cystine, threonine, and tryptophan, increasing the proline content in the feed can improve the lactating power of the sow. The blood globulin powder contains more than 8% of proline, and the use of blood globulin powder in the lactating sow material has a significant effect. 6. Prohibit the abuse of drugs Because certain purposes often require the addition of some drugs, and some drugs on the development of pig reproductive organs, will cause the gilt estrus, ovulation, reduced number of litter and other consequences. For example, in order to make red pigskin bright, many feed manufacturers add a large amount of aphanelic acid, and aphanelic acid has toxic side effects on the reproductive organs of pigs. Dietary supplements take vitamins, minerals and extracts with relatively clear structure-activity relationship as the main raw materials, and supplement the necessary nutrients and biologically active substances for the human body through oral intake to achieve the purpose of improving the body's health and reducing the risk of disease. Available in concentrated forms such as doses or capsules. Foods in traditional form with added nutrients or biologically active substances.
