emulsifiers, enzymes, mycotoxin binders and/or detoxifiers, organic minerals, plant extracts, probiotics and prebiotics.
Points to consider The following six points can be considered for a poultry feed formulation in an antibiotic free era: • Reduce gut viscosity in wheat/barley/oats/triticale-based diets by using NSP-degrading enzymes (xylanase, beta- glucanase, …)
• Use good digestible fat sources that are rich in MCFA (coconut oil or fatty acids, palm kernel oil or fatty acids, insect oil) or high in U/S ratio (C18:1+C18:2+C18:3)/ (C16:0+C18:0)
• Use inert fibre sources and avoid too much fermentable fibre sources by implementing a minimum level of ADF or insoluble dietary fibre and a maximum level of soluble dietary fibre in the diets
• Use coarsely ground cereals before pelleting or add whole wheat to the pellet after pelleting to aid gizzard development
• Reduce the amount of indigestible protein and lower the dietary crude protein level by using good digestible protein sources, more synthetic amino acids and phytase
that also improves ileal amino acid digestibility
• Use additives as potential alternatives for AGPs that have one of the following actions:
a. Antimicrobial, such as ionophore coccidiostats, MCFAs, resins of pine trees, …
b. Anti-inflammatory/anti-oxidative, such as plant extracts, polyphenols, vitamins A/E/C, …
c. Gut integrity supporting, such as betaine, coated/esterified butyric acid, mycotoxin binders/detoxifiers.
This article is a summary of the presentation held during the Virtual All About Feed Forum in May 2021 organised by Misset.
Feed formulations need to reflect and counteract the side effects of an antibiotic free era.
