Abstract

The invention provides a composite microbial feed additive for chicken, which is characterized by comprising probiotics and prebiotics, wherein the probiotics comprise bifidobacterium, lactobacillus acidophilus, enterococcus faecium and bacillus licheniformis; and the prebiotics comprise xylooligosaccharides. The invention also provides a preparation method of the composite microbial feed additive for the chicken. The composite microbial feed additive has the advantages of reducing the morbidity of the chicken effectively, improving daily gain and feed-weight ratio effectively, reducing the production cost, reducing the usage amount of antibiotics effectively and improving the quality of animal byproducts.

Description

technical field [0001] The invention relates to a compound microbial feed additive for chicks and a preparation method thereof, belonging to the technical field of feed additives. Background technique [0002] With the rapid growth of my country's animal husbandry production scale, my country has become the world's largest livestock and poultry production and trade country, among which the production scale of poultry eggs ranks first in the world, and the output of poultry products ranks second in the world. The overall technical level of the industry is low, and bacterial infectious diseases are still mainly controlled by antibiotics, resulting in excessive drug residues in agricultural products such as meat and eggs, and enhanced drug resistance of pathogenic bacteria, which seriously restricts the export of animal husbandry products in my country, and pose a huge threat to human health. [0003] Due to the fact that the hatching equipment in the modern hatchery is extremel...
