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.
Program Chicken Meat
Research organisation University of New England
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.
