Respiratory health of broilers following chronic exposure to airborne endotoxin.

In and around poultry farms, high concentrations of endotoxins are found that have a negative impact on the health of farmers and local residents. However, little is known about the effects of chronic exposure to endotoxins on the health of poultry. The aim of this study was to identify effects of chronic exposure to airborne endotoxins (E.

Effects of on-farm and traditional hatching on welfare, health, and performance of broiler chickens.

In on-farm hatching systems, eggs that have been incubated for 18 D are transported to the broiler farm. After hatching around day 21, the chicks have immediate access to feed and water. By contrast, traditionally hatched chicks are in early life exposed to dust and pathogens in the hatcher, handling procedures, and transport and remain without feed and water until they have arrived on the farm 1 to 3 D after hatching.

Comparison of performance, health and welfare aspects between commercially housed hatchery-hatched and on-farm hatched broiler flocks.

On-farm hatching systems for broiler chicks are increasingly used in practice. We studied whether or not performance, health and welfare aspects differed between commercial flocks hatched on-farm or in a hatchery (control). In two successive production cycles on seven farms, a total of 16 on-farm hatched flocks were paired to 16 control flocks, housed at the same farm.

School Lunch Consumption Among 3 Food Service Providers in New Orleans.

Background: Louisiana has one of the highest rates of overweight and obese children in the United States. The Healthy School Food Collaborative (HSFC) was created to allow New Orleans's schools to select their own healthy school Food Service Provider (FSP) with requirements for higher nutritional standards than traditional options. The goal of this cross-sectional study was to examine whether HSFC membership was associated with lunch consumption rates in elementary school children.
