Impact of Gut Health on Saleable Egg Output in Layers
by Dr. Ruturaj Patil, EW Nutrition GmbH Introduction Gut health in laying hens is a key determinant of productivity, egg hygiene, bird welfare, and economic sustainability in commercial egg production. Beyond nutrient digestion and absorption, the gastrointestinal tract (GIT) plays a central role in immune regulation, microbial homeostasis, and epithelial barrier integrity. Disruption of these […]
Mycotoxins in poultry – External signs can give a hint
Part 4: Paleness By Dr. Inge Heinzl, Editor and Technical Team, EW Nutrition We already showed bad feathering, mouth and beak lesions, bone issues, and foot pad lesions as signs of mycotoxin contamination in the feed, but there is another indicator: paleness. Paleness can signify a low count of red blood cells resulting from blood […]
Mycotoxins in poultry – External signs can give a hint
Part 3: Bone disorders and foot pad lesions By Dr. Inge Heinzl, Editor, and Marisabel Caballero, Global Technical Manager Poultry Bone health is essential for animals and humans. Besides giving structural support, allowing movement, and protecting vital organs, the bones release hormones that are crucial for mineral homeostasis and acid balance and serve as […]
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 […]
