  • Elimination of "fishy" taint in eggs from hens fed diets containing canola meal

    DAQ 303AAWhen 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.

  • Eggs as a source of essential Docosahexaenoic Acid (DHA) - In the diets of weaning infants

    BasketThis project provided a unique, systematic study of the nutritional value of including egg yolk in the weaning diet of breast and formula fed infants in order to address current nutritional issues pertinent to all infants. The study was completed in 1998 and concluded that egg yolks are a safe and nutritious weaning food.

  • Reducing the use of animal by-product meals in layer diets

    UQ 103AEconomic 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. However, use of such ingredients also increases the dietary levels of phytic acid which can have wide ranging ramifications on performance of egg production, quality and nutrient digestibility. This publication details several studies which examined the effectiveness of supplemental phytase in improving the availability of phosphorus, amino acids and energy from plant feed ingredients for laying hens.

  • Inflammatory response to diet in the hindgut of layers

    UNC 14AA2The aim of the  project was to investigate the effects of diet change over the short and long term in chickens, to determine whether this caused an inflammation of the hindgut tissues. 

  • Canola meal and Cottonseed meal in broiler and layer diets

    DAQ 264JThis proposes that the Australian egg and poultry industry to incorporate canola and cottonseed meal in poultry diets. Canola and cottonseed meal is proven to be both economical and high in protein.

  • Impact of sorghum ergot in layer hens

    GRD 4AA2Though sorghum is an important component of layer hen diet, it is highly susceptible to contamination of sorghum ergot. This project aims to determine the safe practical limits for use of ergot contaminated sorghum grain in layer diets.

  • Evaluation of performance of hens fed high nutrient density diets post-moult

    VCA 4AA2This study shows that the low calcium supplementation produces sustained improvements in post-moult performance. 

  • Effects of diet composition, gut microbial status and feed forms on cannibalism in layers

    UNE 72AAThe project aimed to identify both nutritional and husbandry factors that may contribute to increase cannibalism, and to develop strategies to minimise it.

  • Total and Digestible Tryptophan Contents of Feedstuffs for Poultry

    11 Feed and Nutrition FNThis report reviews the amino acid tryptophan which is an essential amino acid in the diet of Australian poultry. Reliable values of total and digestible tryptophan in feedstuffs are needed because tryptophan is often the third most limiting amino acid in poultry diets. Understanding the inclusion of tryptophan in poultry diets will also facilitate the strategic use of commercially available synthetic, feed-grade tryptophan in the Australian poultry industry.

  • How and when to introduce eggs to avoid egg allergies

    EggCup2As egg allergy is the most common food allergy in Australian young children, evidence is emerging to investigate preventative methods for respiratory allergic diseases in childhood. This report analyses whether the timing of egg introduction into infant diets is related to egg allergy in early childhood
