To use feed additives rationally
In order to prevent the diarrhea caused by the deficiency of trace elements and vitamins, it is necessary to add a certain amount of trace elements and vitamins in the diet. Zinc, copper, selenium, vitamin E, and biotin are key to anti-diarrhea in weaned piglets. Some of them are through improving feed conversion efficiency. Improve the body's physical and immune function and play a role, and some are directly antibacterial and antibacterial effect. The appropriate supply of these substances has a significant effect on the prevention of diarrhea, and the specific dosage is used according to the feeding standards. Copper can reduce intestinal urease activity, zinc can kill bacteria, and thus play a role in the prevention of diarrhea.
Piglets have insufficient secretion of digestive enzymes in the body due to changes in weaning stress and dietary components. In addition, the stress has a declining effect on the growth of digestive enzyme activity. therefore. It is necessary to add exogenous enzymes to assist digestion, increase feed digestibility, and reduce indigestion. Enzyme preparations currently used include pepsin, cellulolytic enzymes, saccharide degrading enzymes, amylases and the like. The addition of proteases and amylases can compensate for the lack of endogenous digestive enzymes and increase the utilization of proteins and carbohydrates. Add cellulose
Enzymatic, xylanase and other exogenous enzymes. It can improve the digestibility of oligosaccharides that cannot be decomposed by animals in the diet, and can degrade anti-nutritional factors, reduce the viscosity of the intestine, promote the digestion and absorption of nutrients, eliminate dyspepsia, and reduce the incidence of diarrhea.
When piglets are fed and weaned, adding a certain amount of acidifying agent to the diet can reduce the pH in the stomach of piglets, promote the conversion of pepsinogen to pepsin, increase the digestibility of protein in the diet, and reduce the digestive tract. Incidence. In addition, organic acids have a strong anti-inflammatory, bactericidal ability, can inhibit the proliferation of pathogenic bacteria by reducing the pH, which is conducive to the proliferation of probiotics, to maintain the microecological balance of piglets intestinal, prevent and reduce the incidence of diarrhea in piglets.
Adequate feed intake is very important for the normal growth and development of piglets. Therefore, how to improve the palatability of feed for piglets has become a concern in the pig industry. Piglets are more sensitive to smell and are more sensitive to the taste and smell of feed. Therefore, the use of dietary flavoring agents that do not affect gastrointestinal digestion and absorption in weanling pig diets can not only induce piglets to eat, eat as early as possible, and early weaning, but also increase feed intake, promote growth and development, and reduce diarrhea.
