Think Beyond The Obvious: Exogenous Enzymes as Part of Strategy to Reduce Use of Antibiotics in Poultry Production

1. Persistent increase in the feed prices has been a major constraint in most of the developing countries like India.

2. As a consequence, cheaper and non-conventional feed ingredients have to be used which contain higher percentage of NSP’s.

3. Use of exogenous enzymes in feed provide flexibility in using alternative ingredients without compromising birds performance by reducing anti-nutritional effects and improving nutrients availability and help to aid digestion.

4. PHYTASE:
Phosphorous is a key nutritional requirement for poultry to provide bone growth. Most of the phosphorus contained in animal feed of plant origin exists in the storage form called phytate. Poultry cannot digest phosphorus contained within phytate, since they lack phytase enzyme that breaks down this phytate molecule.

5. XYLANASE:
Break down non-starch polysaccharides (NSPs), including soluble and insoluble arabinoxylans, in the fibre fraction of plant cell walls as well as reducing digesta viscosity and improving digestibility, nutrient release and feed passage rates.

6. PROTEASE:
Increases protein digestibility through hydrolysis of storage and structural proteins, and disrupts interactions of proteins with starch and fibre in the diet.

7. USE OF ENZYMES GIVES BETTER ROI THROUGH IMPROVED BIRD PERFORMANCE TO POULTRY PRODUCERS.

The benefits of exogenous enzymes can be accompanied with experimental values which were conducted in practice ,it is important to see the magnitude of value.
