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.

Aging disaster: mortality, vulnerability, and long-term recovery among Katrina survivors.

Data from this multiyear qualitative study of the effects of Hurricane Katrina and flooding in New Orleans suggest differences in how the elderly cope with disaster. At the time of the disaster, the elderly of New Orleans were at greater risk than other groups, and more elderly died than any other group during the storm and in the first year after. Those who did survive beyond the first year report coping with the long-term disaster aftermath better than the generation below them, experiencing heightened stresses, and feeling as if they are "aging" faster than they should.

Chronic disaster syndrome: Displacement, disaster capitalism, and the eviction of the poor from New Orleans.

Many New Orleans residents who were displaced in 2005 by Hurricanes Katrina and Rita and the subsequent levee failures and floods are still displaced. Living with long-term stress related to loss of family, community, jobs, and social security as well as the continuous struggle for a decent life in unsettled life circumstances, they manifest what we are calling "chronic disaster syndrome." The term refers not only to the physiological and psychological effects generated at the individual level by ongoing social disruption but also to the nexus of socioeconomic and political conditions that produce this situation as a long-term and intractable problem.

Scopolamine and methylscopolamine differentially affect fixed-consecutive-number performance of male and female Wistar rats.

Male and female Wistar rats were trained on a fixed-consecutive-number schedule in which a response on a food lever was followed by the presentation of reinforcement when at least three, but not more than seven responses had been completed on a work lever. Subjects were treated with different doses of the centrally acting cholinergic antagonist scopolamine hydrobromide or the more peripherally active cholinergic antagonist scopolamine methylbromide (0.08, 0.
