Animal feed additive and preparation process thereof

Abstract

An animal feed additive comprises the following components in percentage by weight: 25-29% of lactobacillus, 24-28% of saccharomyces cerevisiae, 33-37% of penicillium decumbens and 10-14% of aspergillus niger. A preparation process comprises the following steps: (1) placing the four strains into four fermentation tanks respectively; (2) placing vectors and nutrients with addition proportion of 3%into each fermentation tank in which the strains account for 97%; (3) controlling the temperature of the fermentation tanks between 25 DEG C and 35 DEG C and humidity between 60% and 70%, and carryingout fermentation under the acid environment with pH value less than 7; (4) taking out the solid obtained after fermentation in each fermentation tank, baking and then processing the solid into powder; and (5) mixing the four kinds of powder. The animal feed additive is prepared by mixing the microbial strains, has all-round nutrition and has no effect on the quality of animals. The preparation process is simple and the cost is lowered.

Description

Technical field [0001] The invention relates to the field of animal feed, in particular to an animal feed additive and a preparation process thereof. Background technique [0002] With the continuous improvement of living standards, people's demand for livestock and poultry has also increased. In order to meet people's needs in life, promote the growth of livestock and poultry and prevent disease, many large-scale livestock and poultry farms use a lot of Growth promoters, hormones, and even antibiotics are used as additives in animal feed, although they speed up the growth of animals and improve their immunity, but they have a negative impact on the quality of animals, resulting in excessive drug residues in animals. It is not good for people's health. Therefore, animal feed additives developed by microbiological technology have been produced. However, the existing microbial additives, due to the interaction between different microorganisms, cannot be prepared by mixing multiple...

Problems solved by technology

[0002] With the continuous improvement of living standards, people's demand for livestock and poultry also increases. In order to meet the needs of people's lives, promote the growth of livestock and poultry and prevent diseases, many large-scale livestock and poultry farms use a large number of Growth-promoting agents, hormones, and even antibiotics are used as animal feed additives. Although they accelerate the growth rate of animals and improve their immunity, they have a negative impact on the quality of animals, resulting in excessive drug residues in animals. detrimental to people's health

Therefore, animal feed additives developed by microbial technology have been produced. However, the existing microbial additives cannot be prepared by mixing a variety of beneficial microorganisms due to the interaction between different microorganisms, resulting in a single type of microbial animal feed additives and low nutritional value. The composition is single; the feed additives that have been developed by mixing a variety of microorganisms have high technological requirements, resulting in high costs and affecting economic benefits
