Effect of Monochromatic LED Light on Reproductive Traits of Laying Hens
New research from China suggests that light colour can affect egg production as well as egg weight, shape, composition, fertility and hatchability....
Effect of Feeder Space During Growing and Laying Periods and Feeding Rate on Broiler Breeder Female Reproduction
A study at North Carolina State University has new light on the effects of feeder management during the rearing and laying phases on broiler breeder performance, revealing that females given similar feeder space during both phases produced the most eggs...
Bacterial Chondronecrosis with Osteomyelitis in Broilers: Influence of Sire and Sex-separate Rearing
Two experiments at the University of Arkansas reveal a significant effect of sire line on the incidence of the leg condition, bacterial chondronecrosis with osteomyelitis (BCO) in broilers, especially after six weeks of age. Rearing the sexes separately...
Controlling Body Weight of Turkey Breeder Hens Without Feed Restriction
A researcher at Iowa State University was able to control turkey hen bodyweight by ad-libitum feeding of a diet of lower nutrient content during the rearing period, without using physical feed restriction. The lighter hens produced more eggs while the...
Understanding the Role of the Skeleton in Egg Production
A guide to bone biology in the laying hen is explained by Hy-Line....
Brooding Temperatures and Heating Costs
Michael Czarick (Extension Engineer) and Brian Fairchild (Extension Poultry Specialist) at the University of Georgia show how heating costs for broiler growing are primarily determined by outside temperature and house condition....
Relationships of Incubational Hatching Egg Characteristics to Post-hatch Bodyweight and Processing Yield in Broilers
After examining the relationships between hatching egg characteristics during incubation and subsequent growth and processing yield in a modern broiler strain, researchers in the US recommend monitoring of mean daily percentage of incubational weight...
Collaborative Studies on Cyanosis in Broiler Breeders
New research at Mississippi State University has increased understanding on cyanosis, a blue or purple colour of the skin in broiler breeders. They found differences in heart function between the three genetic lines they studied and a lower incidence...
Alternative Programmes in Poultry Farming Proposed by Filavie
Alternative programmes in poultry farming have been proposed by Filavie in the continuity of the French plan, Ecoantibio 2012-2017, aimed at reducing antibiotic resistance....
Development of Integrated Livestock Breeding and Management Strategies
Among the projects described in 'A Decade of EU-funded Animal Production Research' from the European Commission is one on the development of integrated livestock breeding and management strategies to improve animal health, product quality and performance...
Effects of Commercial In-ovo Injection of 25-hydroxycholecalciferol on Hatchability and Hatching Chick Quality of Broilers
In-ovo injection of 25-hydroxycholecalciferol may be effective in alleviating the reduction in hatchability in eggs that sometimes occurs after in-ovo injection of commercial diluent, according to recent research in the US....
From Data to Function: Functional Modelling of Poultry Genomics Data
The development of functional modelling applied to poultry genomics is explained by researchers from the University of Arizona....
Attachment of Avian and Mammalian Influenza Viruses to the Respiratory and Reproductive Tracts of Layer Turkey Hens
Several types of influenza virus attached to the lower reproductive tract of turkey hens, report Ohio State University researchers, leading them to warn of the potential risks of venereal transmission and egg-associated flu virus spread in turkeys....
Gut Health in Poultry - The World Within
Good bird management practices - brooding, feed, water, biosecurity and environment - are necessary to maintain gut, and therefore bird, health, welfare and performance, says Dr Richard Bailey, Poultry Health Specialist with Aviagen....
Incubating Eggs at High Altitudes
Steve Tullett, Hatchery Consultant to Aviagen, explains the challenges of hatching chicken eggs at higher altitudes and how to overcome them. ...
