Embodiment 1

[0025] In the application of succinate as a feed additive for improving intestinal health of pigs, succinate is used as a feed additive for improving intestinal health of pigs. Implementation 1 is used as a control group, and the basal feed without succinate is fed during the test growth period of pigs. grain.

[0026] The basal feed ration is a commercialized full-price feed, specifically the following raw materials:

[0027] Corn 65%; Soybean Meal 22%; Wheat Bran 9.25%; Soybean Oil 0.7%; Lysine 0.18%; Threonine 0.01%; CaHPO 3 0.69%; stone powder 0.87%; salt 0.3%; premix 1%. The premixed material is: every kilogram of diet contains: vitamin A 10800IU, vitamin D 3 4000IU, vitamin E 40IU, vitamin K3 4mg, vitamin B 1 6mg, vitamin B 2 12mg, vitamin B 6 6mg, vitamin B 12 0.05mg, biotin 0.2mg, folic acid 2mg, niacin 50mg, D-calcium pantothenate 25mg, iron 100mg, copper 150mg, manganese 40mg, zinc 100mg, iodine 0.5mg, selenium 0.3mg;

[0028] Among them, the nutrient con...

Embodiment 2

[0030] The application of succinate as a feed additive for improving pig intestinal health, succinate as a feed additive for improving pig intestinal health can effectively improve the function of the intestinal barrier of pigs. The animal feed additive is succinate powder, and the succinic acid The salt is sodium succinate powder, and its addition amount is 0.1% of the mass of the basal feed diet.

[0031] The basal feed ration is a commercialized full-price feed, specifically the following raw materials:

[0032] Corn 65%; Soybean Meal 22%; Wheat Bran 9.25%; Soybean Oil 0.7%; Lysine 0.18%; Threonine 0.01%; CaHPO 3 0.69%; stone powder 0.87%; salt 0.3%; premix 1%. The premixed material is: every kilogram of diet contains: vitamin A 10800IU, vitamin D 3 4000IU, vitamin E 40IU, vitamin K3 4mg, vitamin B 1 6mg, vitamin B 2 12mg, vitamin B 6 6mg, vitamin B 12 0.05mg, biotin 0.2mg, folic acid 2mg, niacin 50mg, D-calcium pantothenate 25mg, iron 100mg, copper 150mg, mangan...

Embodiment 3

[0035] The application of succinate as a feed additive for improving pig intestinal health, succinate as a feed additive for improving pig intestinal health can effectively improve the function of the intestinal barrier of pigs. The animal feed additive is succinate powder, and the succinic acid Salt is sodium succinate powder, and its addition amount is 0.5% of the basal feed ration quality.

[0036] The basal feed ration is a commercialized full-price feed, specifically the following raw materials:

[0037] Corn 65%; Soybean Meal 22%; Wheat Bran 9.25%; Soybean Oil 0.7%; Lysine 0.18%; Threonine 0.01%; CaHPO 3 0.69%; stone powder 0.87%; salt 0.3%; premix 1%.

Abstract

The invention discloses an application of succinate as a feed additive for improving health of intestinal tract in pigs, which belongs to the field of the feed additive. According to the application of succinate as the feed additive for improving the health of intestinal health of pigs, the addition accounts for 0.1% to 1% of mass of a basic feed; the succinate is at least one of sodium succinate,potassium succinate, calcium succinate, zinc succinate and ammonium succinate, and is uniformly mixed into the feed in the form of powder. The feed additive has the function of replacing the antibiotic in promoting the growth performance of the pig, is effective for improving the intestinal barrier function of the pig and regulating the intestinal immune response in the pig breeding industry, improves the intestinal health of pigs, and achieves efficient production.

Description

technical field [0001] The invention belongs to the technical field of feed additives, and in particular relates to the application of succinate as a feed additive for improving pig intestinal health. Background technique [0002] Feed additives refer to small or trace substances added during feed processing, production, and use, including nutritive feed additives and non-nutritive feed additives. Feed additives are the raw materials that the modern feed industry will inevitably use. They have obvious effects on strengthening the nutritional value of basic feed, improving animal production performance, ensuring animal health, saving feed cost, and improving the quality of animal products. However, with the development of animal husbandry and feed industry to a higher level, higher requirements are put forward for the safety and environmental protection of feed additives. For example, due to the risk of antibiotic residues to human health, the era of banning feed antibiotics...
