A new double choice model developed in laying hens reveals high preference for L-Alanine

It has been well established that nutrient deficiencies or imbalances increase the risk of feather pecking in layer hens (Kjaer and Bessei, 2013). Marginal...

Immunogenic ingredients in poultry

Among the various immunogenic ingredients, β-mannanase can improve live performance and uniformity in broilers.

Hen feeding for progeny: current research and U.S. field perspectives

Hen nutrition is a key component for good chick viability, welfare, growth, and meat yields. This paper covers some historical and current research on hen feeding to impact progeny, and how the U.S. breeder nutritionist is poised to implement some of these opportunities in the current market conditions.

Phytase influences the inherently different starch digestive dynamics of wheat- and maize- based broiler...

Evaluating the inclusion of exogenous phytase in broiler diets based on wheat and maize to identify whether phytase has an effect on starch digestive dynamics.

Taking NIR beyond feedstuff analysis to enhance turkey production profitability

Turkey production, as with all animal production, has been facing substantial economic challenges in recent years. Poor crop yields, higher competition for raw materials and increased pressure on the food supply chain have resulted in more variability in feed prices and an increased presence of more industrial by-products in feed formulations.

Feeding low protein diets to meat chickens: effects on emissions of toxic and odorous...

Feeding low protein diets formulated to provide all the required amino acids without excesses may reduce putrefaction and therefore the production of toxic and odorous metabolites in the hindgut and litter.

A better understanding of the bacterial populations in the lower gastrointestinal tract can help...

There are a number of things to evaluate when developing a non AGP program. In the poultry industry, we need to move toward a better understanding of the bacterial populations in the lower gastrointestinal tract to further develop poultry feeding programs to reduce the loss in production without the use of an AGP.

An innovation for managing broiler breeder pullets: precision feeding

Precision feeding is about providing the right amount of feed to the right bird at the right time. The precision broiler breeder feeding system developed at the University of Alberta is a sequential feeding system that considers whether one bird at a time qualifies for feed.

Gut health management: breaking paradigms

Recent research on bacteria-host interactions has provided new insights into the role of intestinal bacteria in several physiological processes, which vary from epithelial barrier development to immune properties. Gut health management in poultry and turkey farms implies feeding the good microbiota as a vital component.
