The aim was to evaluate the effect of two different rearing systems, indoor small pens (S) and big with outdoor access (B), on meat quality fatty acid (FA) composition slow growing broiler hybrids (Rowan Ranger [RR] Hubbard CYJA57 [H]). In addition, changes in phospholipid FA composition, due possibility more movement, were investigated. results regarding exclusively influenced by genotype, whe...

Broilers and broiler meat products are highly contaminated with extended spectrum beta-lactamase (ESBL) or plasmid-mediated AmpC beta-lactamase producing Escherichia coli and are considered to be a source for human infections. Both horizontal and vertical transmission might play a role in the presence of these strains in broilers. As not much is known about the presence of these strains in the ...

The aim of this study was to compare the effect of high (33 degrees C) and normal (33-20 degrees C) rearing temperature on growth and plasma levels of the somatotrophic hormones of 2 genetic lines of broiler chickens selected for 6-wk body weight (GL-line) or for feed conversion between 3 and 6 wk of age (FC-line) or for feed conversion between 3 and 6 wk of age (FC-line). Blood samples were co...

An one year epidemiological study was carried out between February 2005 and January 2006 in Belgium to assess the Campylobacter prevalence in free-range broiler production. Three successive broiler flocks on 6 belgian farms were investigated for the presence of Campylobacter ssp. during the rearing period. Each flock was visited four times, before and after the outdoor rearing period. During ea...
