Feed additive for relieving 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 the following components in parts by weight: 25-30 parts of nano-gel coated traditional Chinese medicine powder, 7-10 parts of mixed powder, 2-3 parts of soybean lecithin, 1-3 parts of zinc oxide, and 0.5-1 part of glycerol monolaurate; the preparation method comprises the following steps: adding nano-gum coated traditional Chinese medicine powder, mixed powder, soya bean lecithin, zinc oxide and glycerol monolaurate into a stirring tank for stirring, obtaining a primary feed additive after stirring is finished, and drying the primary feed additive to obtain the feed additive for relieving pig stress after drying is finished. The feed additive disclosed by the invention can achieve a comprehensive stress prevention effect on various stress sources, and can also solve the problems that hormone or antibiotics are abused in the feed additive, some trace elements exceed the standard, the side effect is large, the action time is long, and the drug effect is slow.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to a feed additive for alleviating pig stress and a preparation method thereof. Background technique [0002] Pig stress refers to any action that makes pigs uncomfortable, such as administering antibiotics to pigs, pain during the injection; bitter taste after adding drugs to the feed, aggravating the loss of appetite of pigs; odor and humidity in the pig house environment, etc. The harm of pig stress is mainly manifested in: causing gluconeogenesis, leading to the decline of liver and kidney burden function; causing metabolic acidosis; causing immune system suppression, decreased disease resistance; causing epithelial cell damage, digestive tract and respiratory tract incapacity ;Cause abnormal osmotic pressure and ion imbalance in the body; cause loss of appetite, insufficient nutrient intake, and death of pigs when the stress is severe. [0003] Feed additives refer to s...

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
