Mycotoxins in poultry – External signs can give a hint
Part 1: Impact on Feathering By Dr. Inge Heinzl, Editor, EW Nutrition Mycotoxins are known to decrease health and performance in poultry production. Their modes of action, such as reducing protein synthesis and promoting oxidative stress and apoptosis, lead to cell destruction and lower cell replacement, affecting several organs and tissues. When different stress […]
Overcoming Challenges of Xylanase Inhibitors in Animal Feeds
By Dr. Ajay Awati, Global Director Enzymes, EW Nutrition In recent years, the scientific understanding of xylanase inhibitors (XIs) and their impact on animal nutrition has grown significantly. Xylanase, a crucial enzyme used to enhance nutrient availability in feed, can face challenges from XIs present in cereal grains. This article explores the evolution of plant […]
Mycotoxins in layer and breeder feed impact hens, eggs, hatchery, and chicks
By Technical Team EW Nutrition As the planet’s climate experiences changes, new patterns affect the microbial communities colonizing crops. Recently, several areas of the planet have experienced extreme temperatures, drought, changes in the humid/dry cycles, and an increase in atmospheric carbon dioxide (1,2). As a response, the fungi affecting the crops have shifted their geographical […]
Influence of nutrition and management on eggshell quality
Conference report Many factors affect eggshell quality, such as nutrition, disease, genetics, environmental conditions, age of birds, stress, egg collection and handling, and packaging and transport. Eggshell quality, however, is primarily related to management and nutrition, not genetics or other factors. It is becoming a bigger issue as the length of the laying period has […]

Optimizing DOC quality, part 1: The breeder perspective
Conference report In the Poultry Academy held by EW Nutrition in the fall of last year, Judy Robberts, Technical Service Manager, Aviagen, explained that the success of a breeder flock depends on producing good quality hatching eggs with high hatchability and delivering first quality chicks. With this in mind, we have to ask two essential […]
Optimizing DOC quality, part 2: The hatchery perspective
Conference report At EW Nutrition’s Poultry Academy in the fall of last year, Judy Robberts, Technical Service Manager, Aviagen discussed the impact of the hatchery on chick quality. The transportation and storage of hatching eggs, preventative maintenance, and day-old chick transport all play an essential role. If mismanaged, these areas can negate the benefits of […]
Getting broilers off to a good start: House preparation
Conference report At the recent EW Nutrition Poultry Academy, Judy Robberts, Technical Service Manager, Aviagen discussed the management of broilers for growth & production efficiency. She noted that the first 7 days is the most critical period in the life of a broiler chicken. “In this period chicks are the most efficient at converting feed […]

The trial was carried out over six weeks on Ross […]
Low Crude Protein Diets in Poultry: Understanding the Consequences
Conference report The concept of feeding poultry, specifically broilers and layers, with reduced crude protein (CP) diets is gaining traction among nutritionists. The economic implications of balancing amino acids currently dictate dietary CP levels. At the recent EW Nutrition Poultry Academy in Jakarta, Indonesia, Dr. Steve Leeson, Professor Emeritus at the University of Guelph, Canada, […]
Endotoxins in 250 words
Dr Inge Heinzl, EW Nutrition Endotoxins are… toxic, of course. The part “endo” in their name means that they are part of the bacterial cell, or, to specify it, they are part of the outer membrane of Gram-negative bacteria such as E. coli, Salmonella, Shigella, Klebsiella, and Pseudomonas. When do they occur? Always. Endotoxins are […]
Housing and management strategies to mitigate heat stress in layers
Dr Daniel Valbuena, Global Manager of Technical Services, Hy-Line International – Conference Report Heat stress is one of the major environmental stressors in the poultry industry, especially in regions with high temperatures and high humidity. In EW Nutrition’s Poultry Academy in September, the topic was approached in a comprehensive and practical presentation. A layer’s normal body […]
