Poultry egg quality
Egg quality defines those characteristics of an egg that affect consumer acceptability and preference. Components of quality include shell quality and interior egg quality for shell eggs, and interior egg quality for further processed eggs. The quality of the egg once it is laid cannot be improved. Hence, its maintenance is mostly a preventive process. Egg quality is influenced by several factors including rearing, temperature, humidity, handling, storage, and egg age. Shell quality: There are five major classes of shell defects: integrity, texture, shape, color, and cleanliness. Internal egg quality involves functional, aesthetic and microbiological properties of the egg yolk and albumen. The proportions of components for fresh egg are 32% yolk, 58% albumen and 10% shell. Regarding exterior egg quality, the shell of each egg should be smooth, clean and free of cracks. The eggs should be uniform in colour, size and shape.
One reason for the success of the poultry meat industry has been the consumer perception of a healthy product. Certainly poultry meat contains less fat than do comparable beef or pork products; and in most situations such fat is predominantly unsaturated. Eggs, on the other hand, have suffered more negative consumer attitudes related to health, most of which stemmed from the issue of cholesterol metabolism as perpetuated by the medical profession in...

The modern breeder female is a genetic compromise between two very different selection criteria. This parent must have the genetics for rapid and efficient growth, and yet exhibit a high rate of egg production to supply the next generation of broiler chicks. Reproductive problems arising from decades of genetic selection for meat production traits have impaired the reproductive ability of both broiler parents (Siegel and Dunnington, 1985). Managing the ovary of the broiler breeder is...

Animal science professor Gregoy Bedecarrats has been studying how light affects reproduction patterns in a flock of blind Smokey Joes, a strain of White Leghorn birds. He says a better understanding of how light...

Although the figure is on par with the 20-30 percent estimated average in the European Union, questions remain about the infection rate in Japan.
Not only was the JPA's salmonella survey the first conducted on a nationwide scale, it also covered less than 6 percent of the layer farms in the country.

Adding carrageenans to egg white ovalbumin improves the gelling ability of the egg protein and could spark a "great interest using liquid egg as gelling agents", says research from Spain.
Carrageenan, a popular hydrocolloid used for texture and viscosity in food products, is a gum extracted from seaweed, largely sourced from the Philippines and Indonesia.
A strong pull in global carrageenan stocks, impacted by an increase in demand from China's booming processed food industry, has led to...

A new breed of hen which can produce eggs with extra-hard shells has been developed by scientists in Scotland. Experts at the Roslin Institute - where Dolly the cloned sheep was created - say they have devised a way of selectively breeding hens to produce eggs with toughened shells.
They claim the development will save the UK's poultry industry £17 million per year in damaged eggs. The scientists have been working with colleagues at Glasgow Veterinary School and Leuven University in Belgium...
