Application of glycerol tributyrate in livestock and poultry breeding
The digestive tract is the only way to obtain nutrients, and it is also the channel between external and internal. Therefore, digestive tract health plays an important role in exerting the genetic growth potential of animals and resisting exogenous infection. Glycerol tributyrate acts directly on the digestive tract to provide energy, thus improving the health of the digestive tract and improving the production performance and immune level of livestock and poultry.
In recent years, the study of glycerol tributyrate in pig feed mainly focused on the growth performance, digestive tract morphology, serum biochemical index, antioxidant index, and the influence of digestive tract microorganisms.
Many experiments have found that the proper amount of glycerol tributyrate can increase the average daily gain, reduce the ratio of feed to weight, and improve the digestibility of nutrients in the piglets, as shown in the attached table.
The effect of glycerol tributyrate on the digestive tract was mainly manifested in intestinal morphology, intestinal cell number, villus height, and crypt depth. Research showed that the addition of glycerol tributyrate 0.15% could bring a significant improvement of the villi height/ crypt depth of duodenum, jejunum, and ileum, and the effect of high addition (0.15%) was better than that of low addition (0.08%).
Because glycerol tributyrate can hydrolyze butyrate under the action of lipase, it also has an effect on digestive tract microflora. Some studies have shown that triglyceride increases the number of lactic acid bacteria in feces and decreases the number of Escherichia coli.
For intrauterine growth retardation (IUGR) piglets feeding tributyrin acid glyceride during lactation can promote liver development and alleviate liver inflammation, thus improving liver index and its immune function.
The special physiological structure of poultry makes poultry more vulnerable to pathogenic microorganisms than livestock, and the intestine is the most important infringement site. Therefore, more and more research is to solve the health problems of the poultry digestive tract. The effect of triglyceride on intestinal morphology and microecological balance of the digestive tract has become the focus of recent research.
The continuous development of intensive aquaculture, the increasing density of aquaculture, and the increasing pollution of aquaculture water make aquaculture move physical diseases occur frequently. Some studies have shown that the application of triglyceride can improve the above problems and improve the efficiency of aquaculture.
Butyric acid, as a short-chain fatty acid, plays an important biological role, while glycerol tributyrate is an effective source of butyric acid. The current research is mainly focused on medicine, with less research in animal production. However, glycerol tributyrate can promote growth and regulate significant effects of epidemic and disease prevention, as well as the characteristics of fat aroma, slow metabolism, etc., make them substitute antibiotics. It has great research value.
