The digestive tract development of young piglets is incomplete, and the secretion of endogenous digestive enzymes such as lipase and bile salts in the body is far from enough to digest and absorb the oil in the feed, resulting in waste of fat in the feed. Since emulsifiers can promote fat digestion and absorption, increase feed conversion ratio, and promote animal growth, it is necessary to add exogenous emulsifier to piglet diet to increase the digestibility of fat in livestock and poultry.
First, the type of emulsifier commonly used in feed production
1, the type of emulsifier
There are dozens of emulsifiers that are in compliance with national regulations and approved for use in the market. Among them, there are five kinds of emulsifiers commonly used in animal feed, namely, glycosides, phospholipids, bile salts, Span and spit. Tween and glycerol fatty acid esters. 3.1.1 Glycoside esters mainly include monoglycerides and sucrose esters. Monoglyceride has excellent organoleptic properties, and its color is yellowish or ivory, mostly oily, and also fat or waxy. Sucrose ester is an abbreviation for sucrose fatty acid ester, and is a general term for a class of organic compounds synthesized from sucrose and multi-carbon (C8-C22) fat, and is a hydrophilic emulsifier. The combination of the two can make the emulsification effect of the oil in the animal better.
2, phospholipids
There are dozens of phospholipid emulsifiers, including: refined lecithin, hydrogenated phospholipids, complex phospholipids, modified phospholipids, crude phospholipids, and decolorized phospholipids. In the current animal feed, lecithin is the earliest developed and widely used emulsifier.
3, bile acid salt
Bile acid is a sterol substance that is secreted by the gallbladder and bile into the intestine and is acidic during cholesterol metabolism in animals. Adding bile acid salt can not only achieve the fat in the emulsified diet with lipase, but also enhance the activity of lipase, and can make up for the shortcomings of bile acid secretion in young animals, and improve the utilization of dietary fats. Rate to promote animal growth.
4, and Tween
The Span and Tween are the trade names of sorbitan fatty acid ester and polyoxyethylene sorbitan fatty acid ester, respectively. The platy is a lipophilic emulsifier and the Tween is a hydrophilic emulsifier, both of which include monolaurate, monostearate, monopalmitate, monooleate and tristearate. . Both can be used alone or in combination, and the combination of the two can achieve a better emulsification effect.
5, glycerol fatty acid ester
Glycerol fatty acid esters are products based on glycerides, and their applications are currently in the development stage. The consumption of glyceride derivatives in Europe and the United States accounts for 20% of the total emulsifier consumption. Due to the large range of HLB values ​​of polyglycerol esters, the emulsification ability is strong and the demand is increasing.
Second, the application of emulsifier in piglets
Piglets require a lot of energy during their growth, especially at the young age. Adding oil to the feed can greatly increase the energy level of the diet, meet the energy requirements of the piglets, and increase the feed conversion rate. However, the digestive organs of young animals are underdeveloped, the digestive system is not perfect, and the oil in the feed cannot be fully utilized to meet their own energy needs, resulting in lack of energy in young piglets, which seriously affects their growth and development. As a feed additive capable of promoting fat digestion, the emulsifier has the advantages of emulsifying oil and fat, promoting digestion and absorption, and the like, and overcomes the disadvantage that young piglets cannot fully utilize the fat in the feed. Adding proper amount of nutrient and emulsifier with good emulsifying effect in livestock and poultry feed can significantly improve the growth performance of livestock and poultry and improve the digestibility of energy in the diet. Adding emulsifier to the piglet diet can significantly improve the fat and energy utilization of the feed, enhance the body and promote the rapid growth of piglets.
Summary:
Emulsifier is a kind of feed additive that can promote fat digestion in animals. It can significantly improve the utilization of energy in animal feed and is conducive to the rapid growth of animals. The emulsifier with good nutrition and emulsification effect is used for livestock and poultry feed, which has an important influence on the feeding effect of livestock and poultry. In the future, systematic research should be carried out on the effects of different emulsifiers, the factors affecting the effect of emulsifiers and the utilization technology of emulsifiers, so as to provide a basis for the rational application of emulsifiers and the rational preparation of animal feed.
