The importance of nests for the welfare of laying hens
As the majority of hens in Australia are housed in cages, which is a controversial animal welfare issue for the egg industry, an analysis of nest boxes and their use by laying hens is an important aspect of understanding the effect on bird welfare, behaviour, and ultimately, egg production.
Control of Intestinal Spirochaete Infections in Chickens
Avian Intestinal Spirochaetosis (AIS) is a condition of layers and broiler breeders resulting from infection of the large intestine with anaerobic intestinal spirochaetes, which can lead to wet litter and reduced egg production.The purpose of this project was to develop improved means to control AIS.
Investigating Sanitation of Surface Water for Poultry using Chlorine-IBDV Models
Significant numbers of commercial poultry production sites in Australia rely on surface waters (dams, creeks and rivers) as their major source of drinking water.
The Relationship Between Calcium Nutrition, Appetite, Growth, Production and Skeletal Development in
This research report examines the relationship between body weight, feed intake, calcium nutrition, egg production and skeletal calcium content in three experiments using imported brown egg layers.
Evaluation of performance of tunnel ventilated layer housing
Competitive economic conditions mean that Australian egg producers seek ways to reduce the cost of egg production.Current housing design has proven unable to provide the economically optimum temperatures required by layers during winter and summer.
