This invention discloses a
biological agent suitable for squab growth, its preparation method, and its application, belonging to the field of feed technology. It comprises the following components by weight: 8-40 parts of
microbial agent, 1-10 parts of additive, 1-10 parts of
antioxidant, 0.5-5 parts of
peptidoglycan, and 40-60 parts of
montmorillonite. The
microbial agent includes *
Bifidobacterium animalis*, *
Lactobacillus acidophilus*, *
Lactobacillus paracasei*, and *
Lactobacillus reuteri*. The additive includes at least one of
yeast β-
glucan and
astragalus polysaccharide. The
biological agent for squab growth of this application uses
montmorillonite as a base material. Under the combined action of the
microbial agent, additive,
antioxidant, and
peptidoglycan, it can regulate the intestinal health of breeding pigeons, improve their
immunity, and increase
immune factors in pigeon milk. This can improve the growth performance of squabs, reduce the
culling rate of both breeding and squabs, thereby increasing
economic benefits and showing broad application prospects.
