Disclosure of Invention
The invention aims to solve the technical problem of providing an additive premix for improving the production performance of sows, and the invention is designed to provide high-quality nutrition guarantee for the development of embryos, placentas and fetuses in the sows through a comprehensive application technology of component combination and synergistic effect with definite functions, improve the oxidation resistance of sows and improve the lactation performance of the sows so as to achieve the aim of improving the production performance of the sows.
In order to solve the problems, the additive premix for improving the productivity of the sows, provided by the invention, comprises a carrier and an additive composition, wherein the additive composition comprises glycine consisting of N-carbamylglutamic acid, 4 ', 5, 7-trihydroxyisoflavone, 4', 7-dihydroxyisoflavone, folic acid, vitamin E, biotin and ferrous glycinate.
The carrier is one or a mixture of stone powder, zeolite powder, bentonite, bran, corn starch or defatted rice bran.
The additive composition comprises 5-20 mg/kg of N-carbamylglutamic acid, 10-100mg/kg of 4 ', 5, 7-trihydroxyisoflavone, 10-50 mg/kg of 4', 7-dihydroxyisoflavone, 0.5-1 mg/kg of folic acid, 10-100mg/kg of vitamin E, 0.5-1 mg/kg of biotin and 800 mg/kg of ferrous glycinate.
The N-carbamylglutamic acid in the invention is a structural analogue of N-acetyl glutamic acid, the former can replace the latter to become an allosteric catalyst of carbamyl phosphate synthetase, thereby promoting the conversion of proline and glutamine to citrulline and arginine, increasing the endogenous synthesis of arginine, and arginine has important function on the development of embryo, placenta and fetus.
The sow body is easy to suffer from severe oxidative stress in the perinatal period and the lactation period, and the lactation performance of the sow is influenced. Therefore, the antioxidation is also the problem to be solved for improving the productivity of the sows. In the invention, 4 ', 5, 7-trihydroxyisoflavone and 4', 7-dihydroxyisoflavone are added as polyphenol substances, and the two substances have different numbers of substituted hydroxyl groups and different positions to influence the distribution of electron cloud of a ring, so that the antioxidant capacity cannot be analogized by the number of phenolic hydroxyl groups and similar structures simply, and the combined application of the two substances forms a new antioxidant system which has stronger antioxidant capacity than that of a single component and has more simple effect superposition than that of the two substances. The compound can effectively react with free radicals in vivo and in vitro to generate corresponding ions and molecules, inhibit the generation of the free radicals, eliminate and extinguish the free radicals, terminate the chain reaction of the free radicals, promote the secretion of antioxidant enzymes, inhibit lipid peroxidation, improve the proliferation of mammary epithelial cells of sows, and reduce apoptosis, thereby improving the development of the breasts of the sows and the oxidation resistance of organisms, and improving the weight gain and the survival rate of suckling piglets.
Vitamin E is a potent antioxidant that is an important component of the antioxidant defense system of tissues and cells. Folic acid is involved in purine, pyrimidine and amino acid metabolic processes, so that the synthesis of DNA, RNA and various proteins of sow embryos is promoted, and the embryo formation and the growth and development of fetuses are directly influenced. The biotin is used as a coenzyme and participates in various main metabolic processes, so that the production performance of the sow can be improved, and the disease frequency of the sow can be reduced.
Ferrous glycinate is an amino acid chelated iron source, is easier to absorb than inorganic iron sources such as ferrous sulfate and organic acid iron sources such as ferrous fumarate and ferrous citrate, and is easier to transmit to piglets through sow placentas and sows, thereby promoting the growth and development of piglets, preventing iron-deficiency anemia and reducing the death rate of piglets.
The application method of the additive premix for improving the productivity of the sows, provided by the invention, is respectively adding the additive premix into 4% of premix, 10% of concentrated feed and complete compound feed according to the proportion of 20-50 kg/ton, 5-10 kg/ton and 2-5 kg/ton.
The invention has the advantages and beneficial effects that: the composition composed of the bioactive substances has the functions of not simply superposing all the components but realizing the synergistic effect of all the components, is a set of comprehensive application technology, and the additive premix added with the composition has better effect than the additive premix added with any one component singly, and reduces the dosage of each additive, thereby saving the cost.
