Implementation of a net energy system for the Australian chicken meat industry

Summary

Antinutrients in the diet affect energy and nutrient utilisation on two levels. First, they affect the digestibility of nutrients and hence energy; and secondly, they increase metabolic heat production as the gut system has to work a lot harder to deal with them during digestion and metabolism. The net energy system, through the measurement of heat production and heat increment, will account for most of these effects. This project will invovle several stages of development as follows: Stage 1. The basics for NE measurement Stage 2. Development of NE values Stage 3. Predicted vs measured NE values Stage 4. Commercialscale validation trials Stage 5. Effects of feed additives, including antibiotics on NE values Stage 6. Net energy database for industry Finally, if commercial trials are successful, an Australiawide implementation of the net energy system will occur in consultation with industry.

Objective Summary

Generate a basic database on net energy values using a range of welldefined diets for developing a prediction equation for NE; Determine determined vs predicted NE values of commonly used ingredients in Australia; Conduct semicommercial and commercial scale experiments to examine whether diets formulated on a net energy basis will give a commercial advantage (better FCR, carcass yield, feed cost or N excretion) to the producer, and if this is proven positive, then Produce an NE database for the industry to use.
