Recently, the feed resources and biotransformation innovation team of the Feed Research Institute of the Chinese Academy of Agricultural Sciences revealed the molecular mechanism of desolving starch bacillus to improve the bone health of broilers, confirming its potential application value of alternative antibiotics, and the relevant research results were published in Poultry Science
.
.
At present, probiotics, prebiotics, essential oils and organic acids have shown certain effects in improving the metabolic efficiency and disease resistance of nutrients, but most of the alternatives are still different
from antibiotic growth promoters.
Some strains of Bacillus amylide have the functions of high-yield complex enzymes, inhibition of gram-negative bacteria and regulation of host immunity, and also have the biological characteristics
of strong stress resistance and high proliferation ability.
However, the mechanism of action of decanting Bacillus amylide and antibiotics on broiler chickens remains unclear

However, the mechanism of action of decanting Bacillus amylide and antibiotics on broiler chickens remains unclear
.
Compared with antibiotics, the serum phosphorus and alkaline phosphatase concentrations of broilers fed with Bacillus amylide were higher, and the phosphorus content in the excreta was significantly reduced, indicating that the utilization rate
of phosphorus was significantly improved.
The transcriptional expression levels of phosphorus transporter-1 and phosphorus transporter-2 genes in the duodenum and jejunum of the Bacillus amyloid group were significantly upregulated
.
At the same time, the solution of Bacillus amylide group can increase the calcium and phosphorus content in the tibia and increase the strength
of the tibia.
In addition, dietary supplementation with Bacillus amycinolium can increase the relative abundance of intestinal butyric acid producing bacteria and polyamine-producing bacteria, which has a positive effect on
tibial bone development.
The research results provide a theoretical basis for the improvement of growth and bone health of broiler chickens by desolving Bacillus amylide, which has certain significance
for the ecological breeding of broilers.
