The effect of perches in cages during pullet rearing and egg laying on hen performance, foot health, and plumage

The effect of perches in cages during pullet rearing and egg laying on hen performance, foot health, and plumage.jpg
Enrichment of pullet cages with perches has not been studied. Our objective was to determine if access to metal perches during all or part of the life cycle of caged White Leghorns affected egg traits, foot health, and feather condition. Treatment 1 represented control chickens that never had access to perches during their life cycle. Treatment 2…

Effects of Simple and Disposable Chicken Cages for Experimental Eimeria Infections

Effects of Simple and Disposable Chicken Cages for Experimental Eimeria Infections.jpg
During experimental Eimeria infections in chickens, facilities are often contaminated by fecal oocysts known to be highly resistant to both chemical and enzymatic treatments. Thus, studies using experimental Eimeria infections have been limited due to the difficulty of complete elimination of residual oocysts from both cages and facilities. To…

Effects of group size and repeated social disruption on the serotonergic and dopaminergic systems in two genetic lines of White Leghorn laying hens

Effects of group size and repeated social disruption on the serotonergic and dopaminergic systems in two genetic lines of White Leghorn laying hens.jpg
Farm practices such as increasing group size (GS) and mixing unfamiliar chickens may result in repeated social disruption (RSD) and affect the well-being of hens. To examine whether there are genetic differences in response to social stress, 2 genetic strains of White Leghorn hens were used [i.e., high group production and survivability (HGPS) and…

Enterobacteriaceae and related organisms isolated from nest run cart shelves in commercial shell egg processing facilities

Poultry litter compost for suppression of root-knot nematode on cacao plants

Poultry litter compost for suppression of root-knot nematode on cacao plants.jpg
Poultry litter (poultry manure mixed with the wood shavings that are used for bedding or for covering the soil floor in poultry housing units) compost was investigated as an amendment for suppressing populations of Meloidogyne incognita and increasing plant vigor. The greenhouse and laboratory studies were conducted with mature compost produced in…

Volatile Fatty Acids in Suspended Particulate Matter from a Poultry House Using Rice Hulls as Bedding Materials — A Profile of First Flock after Total Cleanout

Volatile Fatty Acids in Suspended Particulate Matter from a Poultry House Using Rice Hulls as Bedding Materials.jpg
Livestock operations have long been associated with unpleasant odors whether it is a swine, poultry, or dairy operation.

However, as more and more animal production continues to evolve into major concentrated operations, odor emissions from these…

Breeding of tomorrow’s chickens to improve well-being

Breeding of Tomorrows Chickens to Improve Well-Being.jpg
Chickens, as well as other animals, have the ability to change their behavior (behavioral plasticity) and physiology (physiological plasticity) based on the costs and benefits to fit their environment (adaptation). Through natural selection, the population preserves and accumulates traits that are beneficial and rejects those that are detrimental…

Poultry Fancier

Poultry Fancier Volume 10 Number 1.jpg
We have no patience with the people who prejudicially maintain that 'a chicken is a chicken' or in other words take the stand that one "chicken' is as good as another. The ordinary mongrel fowl is in the same class with the razor backed hog, the scrub cow and the plug horse. They constitute the scum of the race. They will sometimes thrive under…

A Start in the Fancy

A Start in The Fancy Cover.jpg
"The man with the courage of his convictions was home from the Score Card Poultry Show with a ten-dollar pullet, and the fact got into the local papers and his neighbors dropped by to condole with him.
'Can you see that much money in a hen?' said one.
'Wasn't it this way?' said another, 'the man you bought her of bought another of you for the…

Survey of small-enterprise chicken operations in the United States

Survey of small-enterprise chicken operations in the United States.jpg
The National Animal Health Monitoring System (NAHMS) Small-Enterprise Chicken study was conducted to better understand bird movement and biosecurity practices of commercial poultry operations having fewer than 20,000 chickens.

Furnished cage system and hen well-being: Comparative effects of furnished cages and battery cages on behavioral exhibitions in White Leghorn chickens

Furnished cage system and hen well-being Comparative effects of furnished cages and battery cages on behavioral exhibitions in White Leghorn chickens.jpg
The battery cage system is being banned in the European Union before or by 2012, and the furnished cage system will be the only cage system allowed after 2012. This study was conducted to examine the different effects of caging systems, furnished cages vs. battery cages, on bird behaviors. One hundred ninety-two 1-d-old non-beak-trimmed Hy-Line…
