Poultry feed additive and preparation method thereof

Abstract

The invention discloses a poultry feed additive and a preparation method thereof, belongs to the technical field of feeds and solves the problems that the existing feed additive is single in raw materials and the effect is poor. The poultry feed additive is formed by combining fermentation products with water contents less than or equal to 16wt%, which are obtained by respectively fermenting bacterium solutions of 15 parts by weight of aspergilli, 15 parts by weight of saccharomycetes, 40 parts by weight of bacilli and 40 parts by weight of compound bacteria; and the preparation method comprises the following steps of: preparing a culture medium, cooling, diluting raw bacteria, inoculating, fermenting, drying, mixing and packaging. The poultry feed additive disclosed by the invention contains 20 probiotic bacteria and has the effects of regulating balance of intestinal flora of an organism, improving immunity, enhancing a digestive function and increasing feed conversion ratio.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a poultry feed additive and a preparation method thereof. Background technique [0002] In recent years, the poultry breeding industry has continued to develop and the scale of breeding has continued to expand. Poultry farming is often infected with diseases. Intestinal diseases are the main cause of poultry farming losses, resulting in a decline in poultry production, an increase in animal mortality, and pollution of poultry products. In order to enhance the physique and disease resistance of poultry and reduce the outbreak of infectious diseases, many professional farming households have adopted the feeding method of feeding antibiotics. This feeding method has played a certain role in disease prevention in actual breeding, but the negative effect is also increasingly apparent. , Antibiotics remain in the biological body, and will produce drug resistance, which has brought food sa...

Problems solved by technology

[0004] Probiotic feed includes single-strain probiotic feed and compound probiotic feed. The optimal conditions for strain fermentation can be selected in the preparation process of single-strain feed additives, while in the preparation process of compound strain additives, due to the anaerobic bacteria and The simultaneous existence of aerobic bacteria or the large difference in the culture conditions of different bacteria cannot achieve the optimal conditions of each bacteria at the same time, which reduces the product quality and product effect
