Summary

This project aims to examine whether formulation of lower dietary CP level in meat chicken feed can be realised and the matrix space spared by a reduction in the protein content exploited through the supplementation of bioactive fibre sources in the feed. This proposal consists of three broiler feeding studies which will be conducted in floor pens for 35 days at University of New England. Broiler chickens (Ross 308 males) will be raised under conditions that is close to commercial practice. Performance including body weight and feed intake will be measured during 10- 24 days, 24-35 days and 10-35 days, and nutrient digestibility, gut morphology, gut microflora and digestive enzymes will be measured at sampling day (d 24). The litter will be scored, and welfare of birds litter will be determined at day 35. The litter will be scored, and welfare of birds litter will be determined at day 35.

Objective Summary

This project aims to examine whether the formulation of lower dietary CP level in meat chicken feed can be realised through the supplementation of different sources of insoluble fibre and protease in the feed. The outcomes of this project will lead to the more effective use of protein in broiler diets to potentially reduce the cost of feed, enhance gut health, minimise the incidence of wet litter and mitigate the nitrogen excretion from birds that results from undigested protein.
