Positive impacts of application of full nutrient and energy matrix with phytase

Application of a full nutrient and energy matrix with phytase can maintain growth performance of broilers and reduce feed costs compared with a minerals matrix alone, found a research by Abiodun Bello and his team from Danisco Animal Nutrition & Health (IFF) and India’s Agrivet Research & Advisory.

The researchers evaluated the effect of stepwise application of a nutrient and energy matrix for a consensus bacterial 6-phytase variant (PhyG) to a corn-based diet, without or with xylanase-amylase-protease (XAP) supplementation.

Based on this research, the researchers conclude that:

• 🐔 The application of dose-dependent reductions in the dietary content of digestible amino acids (AA) and metabolizable energy (ME) on top of a reductions in minerals (Ca, digestible P and Na) to corn-soybean meal-based diets supplemented with PhyG phytase at 1,250 FTU/kg maintained broiler growth performance, bone and carcass characteristics at levels that were not different to those achieved by a nutritionally adequate, unsupplemented diet, over an entire growth cycle.
• 🐔 Application of this ‘full matrix’ with PhyG also enabled a feed cost reduction compared with application of a minerals matrix alone.
• 🐔 Supplementing XAP on top of the phytase with an additional reduction in ME (and digestible AA) similarly maintained bird responses comparable to the nutritionally adequate diet but conferred numerically greater feed cost and sustainability savings compared to PhyG alone.
• 🐔 These findings provide confidence over the application of a ‘full matrix’ for PhyG phytase, with or without XAP, in corn-soybean meal-based diets.
