Overall objective
- To investigate the potential for a combination of an existing multicarbohydrase preparation fortified with a yeast cell wall lytic activity and the yeast derived product(s) as an effective and inexpensive alternative to antibiotics.
Outcomes
- Yeast cell lytic enzyme β1,3-1,6-glucanase significantly depolymerizes yeast cell wall polysaccharides resulting in the release of a variety of nutrients.
- Enzyme/yeast-based supplementation decreased the incidence of Salmonella colonization after challenge in layers and broilers and C. perfringens challenge in broilers.
- Enzyme/yeast-based supplementation modified the gut microbial population in broilers and improved body weight gain and feed conversion ratios in broilers and turkeys.
Application
- A combination of enzyme-pretreated yeast products along with a multi-carbohydrase supplement could serve as an effective and inexpensive alternative technology to replace antibiotic growth promoters in poultry feeding programs.
- The yeast cell wall lytic enzyme β1,3-1,6-glucanase has a commercial potential.
