A feed additive for alleviating pig stress and preparation method thereof

Abstract

The invention discloses a feed additive for relieving pig stress and a preparation method thereof, and belongs to the technical field of feed additives. The feed additive for relieving pig stress comprises, in parts by weight: 25-30 parts after coating with nano-glue Chinese medicine powder, 7-10 parts of mixed powder, 2-3 parts of soybean lecithin, 1-3 parts of zinc oxide, 0.5-1 part of monoglyceride laurate; the preparation method is the traditional Chinese medicine powder coated with nano glue , mixed powder, soybean lecithin, zinc oxide, and monoglyceride laurate are added to the mixing tank for stirring, and the primary feed additive is obtained after the stirring is completed, and the primary feed additive is dried, and the feed additive for relieving pig stress is obtained after drying; The invented feed additive can play a comprehensive preventive effect on various stress sources, and can also solve the problems of abuse of hormones or antibiotics in feed additives, excessive trace elements, large side effects, long acting time and slow drug effect .

Description

Technical field [0001] The present invention relates to the field of feed additive technology, specifically to a feed additive to alleviate pig stress and a preparation method thereof. Background [0002] Pig stress refers to any action that makes pigs uncomfortable, such as applying antibiotics to pigs, pain during beating; The bitter taste after the addition of drugs to the feed, exacerbating the loss of appetite in pigs; Smell, dampness, etc. in the pig house environment. The harm of pig stress is mainly manifested in: causing glycoplasmic effects, resulting in large functional decline in liver and kidney burden; Causes metabolic acidosis; Causes suppression of the immune system, decreased resistance to disease; Causes damage to epithelial cells, incapacitation of the respiratory tract of the digestive tract; Causes abnormal osmolality in the body, ion imbalance; Causes loss of appetite, insufficient nutrient intake, and when stress is severe, it can cause pig death.

AI Technical Summary

Problems solved by technology

[0005] However, the existing feed additives basically belong to a single feed additive. In order to reduce the effects of various stressors, it is usually necessary to mix feed additives, but when mixed, many feed additives will cause mutual influence , for example: choline is easily soluble in water and has a strong alkalinity, which will damage water-soluble vitamins, calcium, and phosphorus; ferrous sulfate, ferrous chloride, and ferrous sulfide will accelerate vitamin A, vitamin D, vitamin E, Vitamin B 1 , Vitamin B 2 oxidative damage, etc.

Therefore, when anti-stress feed additives are used to reduce the effect of stressors, it is difficult to achieve a comprehensive stress-reducing effect on multiple stressors, and there are also abuse of hormones or antibiotics, some trace elements exceed the standard, and the side effects are large. Disadvantages of long time and slow drug effect

[0006] Patent CN102172265B discloses a feed additive for improving the anti-stress ability of growing and fattening pigs and improving meat color and meat quality. It consists of the following components in parts by weight: 0.3-0.5 parts of L-carnitine, 10-20 parts of betaine, and 10 -15 parts, 1-3 parts of selenium preparations, 2-5 parts of iron preparations, 3-5 parts of magnesium preparations, 0.5-1 parts of chromium preparations, 1-2 parts of multivitamins, 5-10 parts of compound amino acids, 1 part of tea polyphenols -5 parts, 5-10 parts of Radix Radix, 20-61.2 parts of carrier; the feed additive has the advantages of no toxic and side effects, beneficial to animal and human health, and alleviating animal stress, but it has long acting time and slow drug effect, so it can only Disadvantages of Alleviating Heat Stress Responses

[0007] Patent CN105831442B discloses an anti-stress and growth-promoting compound feed additive for pigs. The compound feed additive is composed of raw materials γ-aminobutyric acid, tauroursodeoxycholic acid, resveratrol, Grass elongatus, and Grass cerevisiae , Horsetail Grass, Xuan Papaya, Baiqian, Ten Great Contributing Leaves, Toosendan, Mutouhui, Shilianzi, Mishuige, Pearl Vegetable, Bacillus licheniformis freeze-dried powder, Clostridium butyricum freeze-dried powder and carrier Prepared, the carrier is a mixture of corn flour and soybean meal; the compound feed additive can significantly improve the growth and production performance of pigs, improve the nutritional health of pigs under various stress conditions, reduce the diarrhea rate of pigs, Mortality rate, reduce feed-to-meat ratio, improve feed conversion rate, but there are shortcomings such as long action time, slow drug effect, and inability to exert a comprehensive stress effect on multiple stress sources
