Efficacy of Feeding Treatments and Litter Formulations against Shedding of Salmonella in Broilers. (May 2009) Eryn Linnae Larrison, B.S., Texas A&M University Chair of Advisory Committee: Dr. Michael Davis Research has shown that Salmonella can be prevalent in poultry litter, which can be a source of contamination for newly arrived chicks at the poultry house. Since this organism is a pathogen ...

OBJECTIVE High NH3 emissions from poultry houses are reported to have negative impacts on health, welfare and safety of birds and humans, and on the environment. Objective of the present study was to determine the effects of two litter amendments on the NH3 levels in broiler closed houses under hot-humid conditions. METHODS Giving a completely randomize design, nine closed houses, each housed...

the present study was conducted to investigate the effects of deep-stacking process on temperature and pathogenic bacterial survival of broiler litter (bl). broiler litter, deep-stacked to 3 depths (30, 60 or 120 cm) and at 3 moisture levels (15, 25 or 35%) was made use of in a split plot design, experiment last for 21 days. daily temperature of the deep-stacked bl at different depths and at di...

To determine the risk of infection associated with exposure to low-pathogenic avian influenza (AI) virus-contaminated poultry litter, the tenacity of low pathogenic A/Ck/CA/431/00(H6N2), A/Mallard/MN/355779/00(H5N2), and A/turkey/Ohio/313053/04(H3N2) was evaluated. Viral stocks were incubated with poultry litter from commercial flocks at 25°C. Three types of poultry litter, wood shavings, shavi...

effect of heat processing on the nutritive value of broiler litter, as a potential ruminant feedstuff,was studied in two pilot plans, processing through an assessment of chemical composition, proteinfractionation according to cncps as wells digestibility making use of tilley and terry method. in amanufactory located in the city of sabzevar. the average values of dry matter (dm), crude protein(c...

This pilot analysis was conducted with data from 52 conventional grow-out broiler flocks in a prospective field observational study in the southeastern United States during 2003-2006. Each flock was sampled for Salmonella 1 wk before the end of grow-out, upon arrival at the processing plant, and during processing (prior to and immediately after carcass chilling). The broiler litter was sampled ...

Limitations in quality bedding material have resulted in the growing need to re-use litter during broiler farming in some countries, which can be of concern from a food-safety perspective. The aim of this study was to compare the Campylobacter levels in ceca and litter across three litter treatments under commercial farming conditions. The litter treatments were (a) the use of new litter after ...

Viral and bacterial pathogens are a significant economic concern to the US broiler industry and the ecological epicenter for poultry pathogens is the mixture of bedding material, chicken excrement and feathers that comprises the litter of a poultry house. This study used high-throughput sequencing to assess the richness and diversity of poultry litter bacterial communities, and to look for conn...

Increasing size and concentration of production is a long-established and continuing trend in the poultry producing industry. The size of poultry litter produced in this industry shows a sustained and increasing trend too. Daily fresh litter/manure output per is about 30 kg/100 birds. For example, the size of Delmarva broiler farms is average 50,000 heads, and the daily poultry litter productio...
