Feed additive capable of enhancing immunity for growing pig and application of feed additive

Abstract

The invention provides a feed additive capable of enhancing immunity for a growing pig, and application of the feed additive, and discloses the feed additive capable of enhancing the immunity for thegrowing pig, and a use method for the feed additive. The feed additive contains radix astragali polysaccharide, radix isatidis polysaccharide, biotin, folic acid, vitamin C, vitamins and glucose. According to a phenomenon that the pig receives various external stimuli to generate stress in a growth process to cause a situation that an organism is injured, and in combination with the current physiological condition of the pig, trace elements, vitamins and functional substances are applied to the growing pig, and a balance between the vitamins and the trace elements is also considered. Experiments prove that while the digestion and metabolism ability of the pig can be effectively enhanced, the pig is accelerated to grow and develop, the immunity is improved, diseases are prevented and treated, and a death rate is lowered. According to the additive disclosed by the invention, hazards brought by antibiotics in the prior art can be solved. In addition, the feed additive has a wide raw material source, a low price, a simple preparation method and a high social value and economic benefit.

Description

technical field [0001] The invention relates to a feed additive, in particular to an immune-enhancing feed additive for growing pigs and its application. Background technique [0002] In animal production, it is of great significance to improve the immune function through the application of immune enhancers, thereby enhancing the resistance to viral infectious diseases. However, most of the immunostimulants commonly used at present are chemically synthesized, and there are hidden dangers of drug residues. Serious attention must be paid to its dosage, otherwise it will have a counterproductive effect. With people's attention to food safety, plant extracts and biological products have shown certain advantages. They not only have antiviral effects, but also can increase the body's immunity. As immune enhancers, they are safe and low-toxic, and are not easy to produce in animal products. Harmful residues and other advantages. [0003] With the prohibition of using antibiotics ...

Problems solved by technology

[0005] However, Chinese herbal medicine will directly add Chinese herbal medicine to the feed as an immune enhancer. The addition amount is high and the palatability is poor (most of the Chinese herbal medicine tastes bitter), which affects the feed intake of pigs and reduces the production performance. The composition of some Chinese herbal medicines has not yet been clarified. , the side effects of long-term use are unknown
