Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of feed additives and relates to a meat goose feed additive for improving immunity and a preparation method thereof. Background Art
[0002] With the deterioration of the environment and the abuse of many harmful substances, there are more and more epidemic diseases, which are more and more harmful to livestock and poultry, so their survival rate or quality is reduced. The long-term and large-scale use of antibiotics by livestock and poultry has more and more negative effects. Antibiotics kill harmful bacteria while also killing beneficial bacteria. Moreover, the long-term use of antibiotics by livestock and poultry not only produces bacterial resistance to drugs, making drug treatment ineffective after the onset of livestock and poultry, but also drug residues and the impact on the quality of livestock products are more serious problems. Traditional Chinese medicine is increasingly popular in the field of livestock and poultry breeding due to its low toxicity, no subsequent harm, and wide sources. However, many existing Chinese medicine products either have many types of Chinese medicine, resulting in high raw material costs, or have complex processes that are not suitable for large-scale applications, or have unsatisfactory effects and slow efficacy.

[0071] 1. Performance Testing
[0072] The meat goose feed additives prepared in Example 3 and Comparative Examples 1-7 were added to the feed at an addition amount of 5% and used as samples. 800 adult geese were selected and divided into 8 groups, with 100 geese in each group, half of which were male and half were female. The samples were used for feeding three times a day to ensure that the daily feeding amount of an adult goose was 500 g. All geese were caged in a goose house for one month, and the disease rate of each group was recorded. The specific calculation formula was: disease rate = number of illnesses in each group / number of adult geese, and the content of immune protein in the blood was detected.
[0073] The above test results are shown in Table 1:
[0074] Table 1 Test results
[0075] Sample Illness rate% Immune protein pg / mL Example 3 0 0.476 Comparative Example 1 15.6 0.358 Comparative Example 2 16.2 0.361 Comparative Example 3 15.8 0.348 Comparative Example 4 16.0 0.364 Comparative Example 5 13.7 0.378 Comparative Example 6 9.4 0.402 Comparative Example 7 8.7 0.412
[0076] As can be seen from Table 1, the disease rate of adult geese in Example 3 is 0, while the adult geese in Comparative Examples 1-7 all get sick, and the immune protein content in Example 3 is higher than that in Comparative Examples 1-7. Since the four components of the feed additives in Example 3, namely, Acanthopanax cortex powder, Psoralea corylifolia powder, Taraxacum powder and fermented bean curd residue, improve immunity in multiple dimensions, such as stimulating immune cell activity, increasing erythropoiesis, promoting phagocytosis of phagocytes and improving immunity through lysine, while Comparative Examples 1-4 lack one of the components, their immune capacity is reduced; the bean curd residue in Comparative Example 5 is not fermented, and its lysine content is reduced, which in turn affects immunity; in Comparative Examples 6-7, only orange leaf powder or hawthorn powder is added, which affects the food intake of adult geese, thereby reducing immunity.
[0077] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
