GMO poultry feed does not alter chicken or eggs

Poultry completely digest the novel proteins coded for by genes inserted into genetically modified corn and soybeans included in poultry diets and these proteins are not found in chicken meat or eggs.
The novel proteins coded for by the genes inserted in GMO poultry feeds are fully digested by poultry and are not found in chicken meat and eggs.

Hen behavior, nutrition research highlighted at Poultry Science Association meeting

Initial behavior reports from the Coalition for Sustainable Egg Supply project as well as research focusing on layer nutrition and Salmonella enteritidis control were presented at the Poultry Science Association annual meeting.
This year’s Poultry Science Association meeting provided a nice blend of very basic research and applied research presented through technical symposiums, oral and poster presentations of original research. Starting with the "Fundamentals of Feed Efficiency: Animal to Genome" symposium, it became apparent that new technologies would be important at this meeting.

Calcium source particle size has an impact on pullets

Research suggests that bone density can be improved and keel bone deformities reduced if pullets are fed large particle size sources of calcium.
Dietary calcium is required for developing pullets and laying hens to supply adequate quantity and quality calcium for bone calcification, eggshell calcification and other physiological needs. It is important that an adequate quantity of calcium be available as well as adequate amounts of large particle size calcium.

Layer research highlighted at International Scientific Forum

Research topics as varied as LED lighting, low-oil DDGS, calcium particle size and organic methionine sources were presented in Atlanta.
Every year before the International Poultry Expo, scientists and producers from universities and companies worldwide come together for the International Poultry Scientific Forum. Highlights from this year’s forum include presentations on LED lighting for layers, evaluation of DDGS in layer rations, organic alternatives to synthetic methionine, calcium particle size for pullets, quality of egg yolks with oxycarotenoid supplementation and detection of Salmonella enteritidis in trachea tissue.

Feeding low oil DDGS to layers

High oil prices are pushing ethanol producers to remove oil from DDGS, changing the feeding value of this alternative ingredient for poultry producers.
Distillers dried grains with solubles, known as DDGS, have become a mainstay in poultry rations over the past five years, increasing to as much as 20 percent in many laying hen rations. The oil content of DDGS has presented a highly available source of energy for poultry consuming DDGS in the ration.

Animal welfare and Salmonella enteritidis control in layers

Salmonella prevention, animal welfare and other topics of interest for egg producers were presented at the Iowa Egg Industry Symposium.
The Iowa Egg Industry Symposium fall education forum for egg producers, sponsored and organized by the Iowa State University College of Veterinary Medicine and ISU Extension, focused on the current feed ingredient supply situation; animal welfare agreements, certification and management; and strategies to control Salmonella enteriditis in your flock.
