The economics of layer diet amino acid levels throughout lay
With feed costs high and egg prices volatile, its important to explore alternate ways of maximising profits, which may mean challenging traditional production practices. Although formulating a layer diet which meets nutritional requirements at the lowest possible cost seems to make sense, there are alternative ways of formulating diets which can lead to greater profits.

Managing pullets for extended layer life, improved productivity and shell quality
The aim of this project is to understand how different lighting regimes and diets during rearing, either used singularly or together, can improve flock uniformity, egg production and persistency of production, egg size and egg quality, from 16 to 90+ weeks.

Pullet to late layer nutrition
The outcome of this project will provide insight into how to optimise egg shell quality at peak lay through nutritional management from 18 weeks. Hens of lighter and average weight will be trial-fed on diets of either higher or lower nutritional density to 90 weeks.

Separate feeding of calcium for poultry
This series of studies investigated the presence and extent of an ‘appetite’ for an extra-dietary source of Ca in laying hens and established the optimum Ca and P concentrations and ratios of dietary Ca for optimum egg production and nutrient digestibility.

Reducing the use of animal by-product meals in layer diets
Economic constraints and public concerns have compelled the poultry industry to increasingly use a range of cheaper, alternative plant-derived feedstuffs in feed formulations and eliminate the use of animal by-product meals.

Energy requirements of imported layer strains
This study aims to determine the required energy intake of layer hen strain in terms of dietary energy concentration, feed intake, egg output, body weight and body fat content, in order to design diets that are nutrition and cost effective.

Elimination of "fishy" taint in eggs from hens fed diets containing canola meal
When fed canola meal, the presence of a compound called sinapine in the meal often causes hens to lay eggs with a fishy taint.This study aims to identify the exact levels of sinapine that cause this, and to eliminate the phenomenon.

Alternative protein sources for laying hens
The need to expand the protein options available to the poultry industry was the catalyst for this study.

A Comparative Study of the Nutritive Values of Triticale and Wheat for Laying Hens
This study examines whether wheat can be substituted by triticale, a generally cheaper cereal grain, without prejudice to performance of the flock or egg quality.
