February - Factors Causing Poor Pigmentation of Brown-Shelled Eggs

The first documented report of shell pigment loss in brown-shelled eggs was in 1944 when Steggerda and Hollander, while removing dirt from eggshells produced from a small flock of Rhode Island Red Hens, made the surprising discovery that some of the brown pigment also rubbed off. This effect was even more evident when the eggs were rubbed vigorously. Most of the eggs gave up their pigment fairly easily except those possessing a glossy surface.


April - What is Egg Shell Quality and How to Preserve it?

There are many factors that affect the overall quality of the egg shell, but before discussing these factors, it is important to know what makes up the structure of the egg shell. The egg shell consists of about 94% to 97% calcium carbonate. The other three percent is organic matter and egg shell pigment. There are also as many as 8,000 microscopic pores in the shell itself. The outer coating of the shell itself consists of a mucous coating called the cuticle or bloom which is deposited on the shell just prior to lay. This protein like covering helps protect the interior contents of the egg from bacteria penetration through the shell. Egg shell quality is determined by the color, shape, and structure of the shell. Colors can range from white to tints to brown and egg shape can also vary.


June - Egg Drops, Less a Syndrome, More a Production Failure

Egg Drop Syndrome was used to describe the effects of a virus that infected flocks back in the late 1970's. Falls in egg production could be as much as 40 per cent but were commonly 10-15 percent. In present day, layer production ‘egg drops’ or reduced egg production are frequently an indication that something in the system has gone wrong and the flock is showing the farmer that he needs to pay attention to their management, health and welfare to solve the problem and restore production. The difficulties arise when you have to work out which part of the system is failing.


August - Poultry Disease Prevention Checklist

Disease prevention is much less stressful and costly than disease control and recovery. Bio security measures are a critical component of disease prevention. Use this list to rate your disease prevention practices and preparedness. Check the box for all questions to which you can answer “yes”. A score of 80 or better is outstanding, 70 to 79 excellent, 60 to 69 good, 50 to 59 just fair, and 49 or less indicates a definite need for improvement.


December - Rodent Control in Livestock and Poultry Facilities

Rats and mice have long been a problem on farms where food and nesting sites are plentiful. These animals consume and contaminate food destined for livestock and other animals, as well as humans. Each rat on a farm will eat, spoil or damage approximately C$25 worth of grain per year. The adaptability and agility of these animals make getting rid of them particularly difficult. Mice are capable of running up a vertical surface, negotiating a wire like the finest circus performer and can easily jump to a height of 30cm (12 inches) from a flat surface.
