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.
Did you know that eggs can help boost your immune system? With 13 vitamins and minerals and the highest quality protein of any food, eggs can help keep you healthy and fight colds and flu! In total, Americans suffer from an estimated 1 billion colds each year, and children miss 22 million school days because of it 1 . While there is no cure for the common cold, getting a wider variety of immune-boosting nutrients may be one simple way to reduce the risk. Add these...

Government study shows Salmonella levels over five times higher in intensive egg production than organic. The Soil Association can reveal that a recent government survey [1] shows that organic laying hen farms have a significantly lower level of Salmonella. Salmonella is a bacterium that causes one of the commonest forms of food poisoning worldwide. [2] The study showed that 23.4 per cent of farms with caged hens tested...

Results from a recently completed Poultry CRC proof-of-concept project, Using "machine vision" to count hens and reduce egg breakage, has demonstrated that ‘machine vision’, or video image analysis (VIA – the ability of a computer to ‘see’), can be used to monitor egg belts for potential blockages and has the potential for effectively counting hens. Testing under commercial conditions has demonstrated that the ability of a...

Economic losses associated with the incidence of egg shell defects are important when evaluating the profitability of a layer operation (Bell, 1998; Gomez- Basauri, 1997; Roland, 1988; Hamilton et al., 1979). Worldwide estimates of reduced shell quality leading to egg breakage have been found to range from 6 to 8% (Anderson and Carter, 1976; Folkerts, 1976; Roland, 1977; Hamilton et al., 1979). In the USA alone this has been estimated to be around 8% (Roland, 1988). Shell defects are not...

While some animal rights organizations have been campaigning to ban traditional cage eggs in the U.S., it turns out that these eggs may be best for the environment. A study conducted by Adrian Williams, PhD., senior research fellow at Cranfield University in the United Kingdom, found that the traditional cage egg production currently used by most U.S. egg farmers decreases the industry's effects on global warming by 10 percent, while converting to all free-range egg production would...

Numerous estimates have been made concerning the total economic losses associated with accidental egg breakage in the table egg industry of the US. Estimates as high as $478 million per year have been published (Roland, 1988). The many estimates vary due to differences in methods of estimating the percentage of eggs cracked or lost and the relative prices used by the authors to establish values. A number of excellent research papers and reviews of the subject have been published...

IMPORTANCE AND PREVIOUS WORK Less than one-third of the phosphorus (P) contained in feed ingredients of plant origin is biologically available to monogastric animals (NRC, 1994). The remainder of the phosphorus is tied up as phytate (phytic acid or myoinositol hexaphosphate) and monogastrics as a general rule lack the enzyme(s) necessary to hydrolyze phytate down to phosphorus and inositol (Peeler, 1972; Lynch, 1996). Therefore, inorganic...

Why does man want to alter mother nature’s most perfect food? After all, ‘if it ain’t broke, don’t fix it.’ The desire to alter the composition of an egg is not due to an innate flaw, but rather to produce an egg with unique features. Such features are an increased mineral and (or) vitamin content, lower lipid and cholesterol concentration and altered fatty acid profile. One of the first researchers to document the ability to change the nutrient profile of the egg was Cruickshank...

A team of scientists from Scotland have recently engineered special kind of chicken, which lays eggs with disease-treating properties.
Previous studies have already made cows, sheep, and goats that pump out protein drugs in their milk, but recent researches carried out by Edinburgh's Roslin Institute claim chickens are a better choice due to their low costs, less acquirement of room, and faster growth.
The team of researchers changed chickens' DNA so that the birds' cells made two...

Recently, China's artificial products have been under the spotlight in Korea. Several mainstream Korean media have reported on the process of making artificial eggs in China, which has stirred up panic and caused great concern among Koreans. On September 1 and 2, the Munhwa Broadcasting Corporation (MBC) did a documentary titled "Life without products made in China." The show followed the daily lives of three families in South Korea, the US, and Japan who refused to use...

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...

A strain of chickens that are naturally blind start reproduction earlier and produce more eggs per cycle than their sighted counterparts, a University of Guelph researcher is finding. Now he’s working to understand what influences the increased production in blind birds. 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...

Consuming two eggs a day significantly enhances weight loss efforts, according to the results of a new study released this week. The study shows that people who included eggs for breakfast as part of a kilojoule-controlled weight loss plan experienced a 65 percent greater reduction in weight and an 83 percent decrease in waist circumference, compared to a dieting group who ate bagels for breakfast.
The randomised trial placed 152 overweight/obese men and women on a reduced-kilojoule diet for...
