Broiler Chickens Supplemented with β-Mannanases and Bacteriophages
The objective of this study was to investigate the effects of supplementing broiler diets with Mn and BPs on production performance, gut health, and appendix microbial communities.
Results showed that supplementation with Mn and/or BPs had similar effects on productivity as the antibiotic control group while improving immune response and gut morphology. In addition, supplementation with Mn+BPs resulted in a decrease in proteobacteria in the cecal microbiota, suggesting potential application as an alternative to antibiotics for maintaining gut health in poultry.
Overall, these results demonstrate the potential benefits of including Mn and BP in broiler diets.

- The purpose of this study was to investigate the effects of β-mannanases (MNs) and bacteriophages (BPs) on production performance, gut health and cecal microbiota in broilers.
- 600 one-day-old broilers were divided into four groups and fed one of four diets: CON – corn-soy meal + 10 ppm enramycin (ENR); MN: CON + 500 ppm MN; BP: CON + 500 ppm BP; MN + BP: BP + 500 ppm MN.
- The results showed that the combination of MN+BP has potential for poultry nutrition, but further experiments are needed to confirm this hypothesis.
This study was conducted to evaluate the productive performance, intestinal health, and description of the cecum microbiota in broilers supplemented with β-mannanases (MNs) and bacteriophages (BPs).
Six hundred one-day-old broilers were divided into four groups and fed one of the following diets: CON-corn-soybean meal + 10 ppm enramycin (ENR); MN: CON + 500 ppm MN; BP: CON + 500 ppm BP; MN + BP: BP + 500 ppm MN.
The BP and MN factors showed similar performances to ENR. MN improved the concentration of IgA in the jejunum at 35 days of age. The morphometric index (IM) of the thymus increased by adding MN, while BP increased the liver and thymus IM.
The histological analysis showed that BP and MN improved the intestinal morphology. MN + BP showed a tendency to decrease the abundance of Proteobacteria and increase the abundance of Bacteroidetes, indicating better microbiota function.
In conclusion, our results demonstrate that the combination of MN + BP has potential in poultry nutrition; however, we highly recommend further experiments to confirm this hypothesis.
