The poultry industry continues to rapidly expand throughout many regions of the world. World production of chicken and eggs is twice the level of only two decades ago. The genetic potential of the broiler, breeder, and egg-type layer has changed dramatically, resulting in a higher producing but more fragile chicken. Thus, the commercial chicken of today requires improved management practices. In t ...

Intestinal parasites (worms) are very common in chickens in the backyard type poultry flocks. The presence of a few parasites does not usually cause a problem. However, large numbers can have a devastating effect on growth, egg production, and overall health. The concentration of parasite eggs in the chickens environment is one factor which plays a major role in determining the severity of the inf ...

Fertile egg production and incubation and production of broiler meat are both an art and a science. People have taken full control of incubating fertile eggs by artificial means to supply the increasing world demand for poultry meat. It is estimated that worldwide more than 35 billion fertile broiler eggs are incubated annually. If eggs were still incubated naturally and broilers raised in small b ...

Protecting poultry against disease involves more than simply administering preventive vaccines. Disease prevention is a complex and multifaceted process. Vaccine quality is commonly blamed when a disease occurs; however, there are usually other factors responsible. A comprehensive investigation is often called for to identify the cause(s) and to resolve the problem. Commercial poultry farms have ...

Infectious bursal disease (IBD) is an acute and highly contagious viral infection of immature chickens. IBD is characterized by destruction of lymphocytes in the bursa of Fabricius (BF) and to a lesser extent in other lymphoid organs. The disease is a major problem in concentrated poultry production areas throughout the world. However, it is often not recognized due to a subclinical form. Affected ...

Avian influenza is a viral disease affecting the respiratory, digestive and/or nervous system of many species of birds. Avian influenza virus infection can occur in most, if not all, species of birds, both domestic and wild. Influenza viruses vary widely in their ability to cause disease (pathogenicity) and their ability to spread among birds. Wild species of birds usually do not develop clinical ...

Detailed information describing the categorization and incidence of embryo malpositions and deformities in commercial poultry is not readily available. Additionally, there is often little consistency in these data among hatcheries. Any decrease in the number of usable chicks may result in substantial economic loss to poultry integrations. In a typical hatch, it is common to lose about 1-2% of the ...

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 e ...

More than 30 billion broiler chicks are produced worldwide on an annual basis. Fifteen billion of these are produced in the Americas. Due to the poultry industry's tendency towards more intensive production practices and increased automation, the tender loving care once afforded to chickens in grow-out has been replaced with a mass production mentality. As a result, newly hatched chicks are often ...

"Feed passage," or, more accurately, the passage of undigested feed in the feces of broilers, continues to be reported in broiler integrations on a sporadic basis. The incidence and severity are much lower at present than during 1996 when global reports of feed passage occurred following consecutive years of poor grain harvests. At that time, broilers were passing undigested feed in the feces and ...
