Measurement of energy utilization in chickens

Although corn prices have dropped from historic highs in the past years, energy continues to be one of the driving costs in poultry feeding....

Using more bioavailable sources of trace minerals pays off

A study of broiler breeder performance was conducted using three separate minerals programmes. The objective was to determine if productivity could be maintained at...

Influence of feed form and particle size on the performance and nutrient utilisation of...

The present experiment was designed to examine the influence of feed form and particle size in maize-based diets on the performance and nutrient utilisation...

In vivo digestion of GM proteins in laying hens

Despite all of the positive effects of modern technologies to improve corn and soybean yields, the consumer often has a different perception of the...

Phosphorus: how low can we go in broiler diets?

Phosphorus (P) is essential for all forms of life. Dietary P content either in excess of, or below requirements may adversely affect broiler performance....

The effect of microbial challenge on the intestinal proteome of broilers

In broiler production intestinal health and function is paramount to achieving efficient feed utilisation and growth. Uncovering the localised molecular mechanisms that occur during the...

Bacillus Subtilis improves performance of broilers fed medicated or non-medicated feed

Animal digestive health is key to obtain optimal performance. Antibiotic growth promoters (AGPs) have long been shown to be very effective to develop and...

Feather-eating hens show specific essential amino acid appetites in a double-choice model

Nutritional balance is one of the major considerations to prevent severe feather pecking in layer hens. Individual variation in digestive and metabolic efficiencies and...

Feed Conversion Ratio optimized for farmer profit

The farmers’ cost for animal feed is one of the main expenditures consisting of 60-70% of the overall producer costs. These producer costs are...

New applications such as superdosing of phytase to maximize phytate destruction to improve performance...

It is well documented that phytase supplementation in broiler diets improves P and Ca utilization through the destruction of phytate (IP6) and thereby allows...

The relationship between feed particle size, gizzard development and broiler performance

Anatomy of the stomach The stomach of the chicken consists of two chambers, the proventriculus or glandular stomach and the gizzard or muscular stomach. The...

Flexible Feed Formulation with GALLIPRO

Facing challenging goals The goal of the poultry industry is to provide consumers with safe food, while promoting poultry health and welfare, in addition to carefully...

Feed borne mycotoxins: the threat to poultry?

Mycotoxins are metabolites produced by molds (fungi) that can infest crops pre-harvest and can continue to flourish under sub-optimal storage conditions. Grains with high...

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.
