Abstract

The invention discloses a complex probiotic preparation capable of improving intestinal function of a chick and a preparation method thereof. The complex probiotic preparation comprises mixed bacteriasolution and a composite supporter, wherein the mixed bacteria solution is mixed bacteria solution of bacillus velezensis, enterococci and stenotrophomonas maltophilia, and the composite supporter isa mixture of zeolite powder and glucose powder. The preparation method comprises the following steps: firstly mixing the mixed bacteria solution with expanded corn flour, and then mixing with the composite supporter. Compared with the prior art, the complex probiotic preparation is applied to chick feed additives, has the effects of aiding digestion and softening faeces, can improve immunity andgrowth performance of the chick and is especially applicable to feeding of chicks incomplete in development of intestinal function, and thrifty rate of dayold chicks is improved.

Description

technical field [0001] The invention relates to a microbial preparation, in particular to a compound probiotic agent for improving intestinal function of chicks and a preparation method thereof. Background technique [0002] In recent years, the level of my country's animal husbandry industry has grown rapidly, and livestock breeding has played an important supporting role in my country's economic industry and its proportion in the national economy is increasing day by day. However, there has always been a huge problem that has been plaguing farmers, such as many diseases in livestock and poultry, and low product quality. At the same time, food safety problems caused by drug residues in meat, eggs, milk, and food are threatening human health. As food safety issues become increasingly prominent, livestock, poultry, meat, eggs, and milk products that do not contain additives such as antibiotics and hormones have gradually replaced the previous products and become people's pref...
