Dysbacteriosis, an imbalance in gut microbiota, impairs nutrient absorption and growth in broilers. Severe cases can cause wet litter and high mortality. AGPs have long been used to enhance gut health and performance, but their prolonged use raises concerns over antimicrobial resistance in birds and humans. Removing AGPs from broiler diets has reduced performance and increased gastrointestinal tra ...

Gut health challenge is one of the major factors affecting production and profitability in commercial laying hens. In addition, chronic heat stress results in lowered feed intake, egg production, egg quality, gut microbiome and also impairs acid-base balance in laying birds. Numerous data support that laying birds fed with organic acid improved egg production and quality (Sakdee et al., 2018; Zhan ...

Increasing prices and low availability of common feed raw materials resulted in the use of alternative ingredients in animal production. These ingredients are often characterised by a high amount of soluble fibre resulting in lower performance and intestinal health issues that limits their inclusion rate in the diet. Bacillus amyloliquefaciens CECT 5940 (Ba) is a probiotic that can produce various ...
