Animal feed additive

Abstract

The invention discloses an animal feed additive. The animal feed additive comprises the following components of lecithin, rhamnolipid, polyglycerol fatty acid ester, succinylated monoglycerides and water soluble starch at the weight ratio of 2:0.2:0.6:1.4:5.8. The animal feed additive disclosed by the invention has good tolerance on complex physiological environments in animals, is strong in emulsifying capacity and high in stability and overcomes the problems that the exertion of emulsifying capacity of a conventional feed emulsifier is influenced because the conventional feed emulsifier is easily damaged by gastric acid and ionic concentration. The animal feed additive has the beneficial effects that the emulsification of fat, particularly animal fat in digestive tracts of the animals is beneficially enhanced, the contact area between fat particles and lipase is increased, digestive functions of gastrointestinal tracts are enhanced, the liver metabolism is enhanced, the emulsification and absorption of fat are promoted, nutrition metabolism of organisms is improved, and production performance of the animals is obviously increased; the grease digestive absorption and utilization rates of the animals are increased, so that the dosage of the grease can be reduced, and the cost can be lowered; the absorption of lipid-soluble vitamin is promoted; diseases of the digestive tracts, such as diarrhea and enteritis caused by indigestion of fat are reduced.

Description

technical field [0001] The invention relates to the field of additives, in particular to an animal feed additive. Background technique [0002] Fat is the main energy-supplying substance in poultry feed. In order to improve animal production performance in modern commercial farming, a higher proportion of fat is usually added to the feed formula. However, due to its non-hydrophilic characteristics, the digestion and absorption of fat by animals has certain particularities. The digestion and absorption of fat is mainly carried out in the small intestine. Since fat is insoluble in water, and the enzymatic reaction in the body is carried out in aqueous solution, fat must first be emulsified before it can be digested. [0003] The emulsifier present in animals is bile salt from the gallbladder. It first purifies fat, reduces its surface tension, and then emulsifies fat into very fine emulsified particles, which are then completely decomposed by pancreatic lipase in the small in...

AI Technical Summary

Problems solved by technology

Among them, bile salts are natural emulsifiers secreted by the liver of animals. The academic community has not yet formed a unified opinion on whether the addition of exogenous sources into the digestive tract of animals will cause feedback from the animal liver to inhibit the secretion of bile. The emulsification effect and emulsification stability are poor; the commercially available phospholipid emulsifier is compounded with ordinary phospholipids and some other surfactants, the emulsification ability and emulsification stability are not strong, and the effect is poor
