Abstract

The invention provides a feed additive for enhancing the immunity of calves and a method for preparing the feed additive. The feed additive is made of radix aristolochiae, ganoderma, folium perillae, herba lobeliae chinensis, fructus evodiae, herba portulacae and allium sativum. The feed additive and the method have the advantages that obvious effects for improving immune regulation of the calves and enhancing immunity functions can be realized by the feed additive, the difficult problems of pathogenic medicine resistance and medicine tolerance due to chemotherapeutic agents and medicines such as antibiotics for preventing and treating diseases of existing calves can be solved, the food consumption of the calves can be increased, and the calves can grow fast.

Description

technical field [0001] The invention belongs to the technical field of breeding, and in particular relates to a feed additive for enhancing the immunity of calves and a preparation method thereof. Background technique [0002] Calves are small in weight, poor in physique, have an undeveloped immune system, and have low resistance. Many small unfavorable factors can lead to disease. At present, in terms of disease prevention and resistance of calves, antibiotics are mostly used as feed additives or directly injected to enhance the immunity of calves and reduce the incidence of calves. However, with the continuous mutation of pathogenic microorganisms, the limitations of antibiotics and the harm they bring are gradually exposed. For example, the use of a large number of antibiotics not only increases the drug resistance of calves during their growth, but also gradually increases their resistance. It is low, and it also makes the residue in beef and beef products higher, which...
