3 results about "Increasing lactation" patented technology

The application discloses a composition with lactation promoting effect and application thereof. Researches of the application show that oyster peptide can promote mammary gland development, improve lactation related hormones and promote lactation. Meanwhile, the application provides a composition with lactation promoting effect, which comprises oyster peptide, astragalus polysaccharide and soybean isoflavone. Researches show that the composition of oyster peptide, astragalus polysaccharide and soybean isoflavone can improve lactation performance of mammals and increase lactation yield. The oyster peptide has a synergistic effect when being used in combination with astragalus polysaccharide and soybean isoflavone, and can promote lactation and mammary gland development, and improve lactation related hormones. The composition is prepared into oyster peptide lactation promoting granules, and the components are green, natural, safe, nutritious, non-toxic and non-side effect, can effectively increase the hourly lactation yield of postpartum lactation deficient mice, serum and mammary gland tissue PRL, PRLR level and mammary gland organ index, and has an improving effect on postpartum lactation deficiency.

The invention relates to the technical field of sow feed processing, and particularly discloses a lactating sow feed capable of increasing the lactation yield of sows and a preparation method thereof.The lactating sow feed is prepared from, by weight, base materials and active materials, the base materials comprise 400-450 parts of corn, 200-230 parts of soybean meal, 38-42 parts of whey powder, 68-72 parts of bran, 19-21 parts of fish meal and 33-37 parts of vitamin and mineral premix, and the active materials are mixed with the base materials; 15 to 18 parts of mineral supplement and 120 to 130 parts of maltodextrin; the active material is prepared from 0.9 to 1.1 parts of enzyme group material, 15 to 25 parts of maltodextrin, 6 to 10 parts of phospholipid oil-loaded microcapsule and 3 to 5 parts of organic zinc-biotin-lysine ternary complex. Sufficient unsaturated fatty acid raw materials are provided for mammary gland cells, so that milk fat synthesis is promoted, and milk quality is improved; the bioavailability of Zn is remarkably improved through a chelating structure, Zn participates in mammary gland metabolism and protein synthesis, lysine promotes milk protein synthesis, and biotin improves fatty acid metabolism and mammary gland epithelium functions and synergistically enhances lactation capacity.

The application provides a feed additive and application thereof. The feed additive comprises the following components in parts by weight: 20-30 parts of flaxseed, 10-20 parts of perilla seed, 1-2 parts of choline, 0.05-0.15 parts of vitamin E, 0.1-0.2 parts of zinc sulfate, 0.01-0.05 parts of nicotinic acid and 48-68 parts of wheat bran. The feed additive and the feed containing the feed additive provided by the application are used for 6-13 month old non-pregnant cows, the mammary gland development of the cows in puberty is intervened, the growth of the mammary gland fat pad in the period is promoted, the growth and development of the lactiferous duct in the gestation period are provided with a material basis, the number of the lactiferous duct and the acinus is increased, and thus the initial number of the mammary epithelial cells in the lactation period is increased, and the peak milk yield of the cows after delivery is improved.
