Problems solved by technology

The disadvantages of enzyme preparations and prebiotics are poor thermal stability and easy inactivation, which will cause inactivation no matter under heat treatment conditions such as granulation and puffing or long-term storage; the addition ratio of acid preparations is large (1% to 3%), and the cost is high , the activity of vitamins is easily destroyed when making compound premixes, and the function is limited; Chinese herbal medicine preparations are mostly crude products, and the effect is unstable. If they are refined and extracted, the processing cost is high, and there are shortcomings such as limited resources when used in large quantities.

Embodiment 1～11

[0033] The preparation method of the composition in the following implementation is: take each component according to the proportion, and then fully stir it evenly to obtain the product. The components and contents of each embodiment are shown in Table 1 (the ratios listed in Table 1 are weight ratios). The implementation effect of each embodiment is as follows:

[0034] Take the composition prepared in Examples 1-7, add 4.0g of the composition per kilogram of feed to feed growing pigs, the results show that the total antioxidant capacity, SOD and GSH-PX activities of growing pigs have been improved respectively, MDA and NO The serum IgA, IgG and IgM contents were respectively increased.

[0035] Taking the composition prepared in Example 8, feeding growing pigs with 4.0 g of the composition per kilogram of feed, the results showed that the total antioxidant capacity, SOD and GSH-PX activities of growing pigs were increased by 54.75%, 19.69% and 11.64% respectively , MDA and...

Abstract

The invention discloses an anti-oxidant composition for improving animal immune function and a preparation method thereof, belonging to the field of feed additive. The composition comprises the following ingredients: 2.0-18.0 wt% of vitamin E, 5.0-30.0 wt% of vitamin C, 2.0-40.0 wt% of thioctic acid, 1.0-25.0 wt% of antioxidants, and the balance consisting of corncob powder, wherein, the antioxidants are mixtures of one or more of daidzein, astragalus polysaccharides and tea polyphenol. According to basic theory of free radical biology, various antioxidants are used to form an antioxidant network, because of the synergism among the antioxidants, the oxidation resistance of the animal that takes the composition is enhanced greatly, so that the immune tissue and organs of the organism are protected, and the animal immune function is improved.

Description

technical field [0001] The invention relates to a feed additive and a preparation method thereof, in particular to an antioxidant composition for improving animal immune function and a preparation method thereof. Background technique [0002] Studies have shown that adding low doses of antibiotics to feed can prevent diseases, promote growth, and improve feed conversion rates in animals. However, long-term use of antibiotics will lead to drug residues and drug resistance of pathogenic microorganisms, causing food safety hazards and endangering the public. healthy. Therefore, with the improvement of people's food safety awareness, there is an urgent need to use green feed additives to produce green, pollution-free and safe animal products. [0003] A large number of researches on antibiotic substitutes have been carried out at home and abroad, and enzyme preparations, prebiotics, Chinese herbal medicines, oligosaccharides, acidulants and other antibiotic substitutes have bee...
