Description

technical field

[0001] The invention belongs to the technical field of feed science and feed additives, and relates to a biological feed additive, in particular to a compound biological feed additive for laying hens. Background technique

[0002] People's understanding of food safety is gradually deepening, and people are paying more and more attention to green and nutritious animal products. For a long time, a large number of chemically synthesized feed additives and chemicals, such as antibiotics, growth-stimulating hormones and preservatives, have been widely used in feed, which has brought about great negative effects while promoting the development of animal husbandry, especially the resistance caused by the abuse of antibiotics. Drugs and drug residues bring great harm to human health.

[0003] And at present, the eggs produced by large-scale breeding hens have high yield and large individual volume, but the taste and nutritional value are often not as good as eggs pr...
