Different infectious bursal disease virus (IBDV) live vaccines (intermediate, intermediate plus) were compared for their immunosuppressive abilities in specific-pathogen-free (SPF) layer-type chickens or commercial broilers. The Newcastle disease virus (NDV) vaccination model was applied to determine not only IBDV-induced immunosuppression but also bilateral effects between IBDV and NDV. None o...

This study was conducted to evaluate messenger RNA (mRNA) expression of genes that are involved in energy metabolism and mitochondrial biogenesis: avian adenine nucleotide translocator (avANT), cytochrome oxidase III (COX III), inducible nitric oxide synthase (iNOS), peroxisome proliferator-activated receptor-gamma (PPAR-gamma), avian PPAR-gamma coactivator-1alpha (avPGC-1alpha), and avian unco...

Accurate identification and optimal culturing procedures for Campylobacter spp. from live broilers are needed for epidemiological studies. Because there is no standardized protocol, we designed and conducted studies to evaluate different selective media for the culturing and isolation of Campylobacter spp. from cecal and fecal samples obtained from battery-reared and commercial broilers. Five m...

The objectives of the present study were to examine the level of radiocesium deposit in meat and edible organs of broiler chickens as well as to investigate efficiency of natural sepiolite in reducing Cs deposition in meat, liver and gizzard of alimentary contaminated broiler chickens. Broiler chickens (six weeks of age) were fed with the standard diet and each broiler was given a single oral d...

This study investigated the teratogenicity of ethanol in several different strains of chickens. The chick embryo provides a useful model for studying the fetal alcohol syndrome. Two broad classifications of chicks, each containing many strains, are commercially available for use: broilers and layers. Teratogenicity of ethanol in broilers and layers was studied by examining three different param...

BACKGROUND The present study was intended to determine the prevalence and identification of species involved causing coccidiosis in broilers rearing under traditional farming system in Mirpur, Azad Kashmir, Pakistan. For the current study, a convenient sampling technique was carried out. A total of 7814 broilers (aged 1 to 6 weeks) were submitted to the Disease Diagnostic Laboratory of Livestoc...

AIM The purpose of this study was to investigate the prevalence of enteropathogenic Escherichia coli (EPEC) and shiga toxin producing E. coli (STEC) strains in healthy broilers in Iran. BACKGROUND STEC and EPEC strains as diarrheagenic E. coli are among the most prevalent causative agents in acute diarrhea. Domestic animals, mainly cattle and sheep, have been implicated as the principal reser...

Salmonella enterica strains isolated in Okinawa between 1995 and 2005 were analyzed with respect to their serovars and antimicrobial susceptibility, and pulsed-field gel electrophoresis (PFGE) was used to examine their digestion patterns. A total of 1,071 isolates, including 610 from humans, 358 from animal rectal swabs and 103 from meat obtained at grocery stores, were examined. The first 3 mo...

We evaluated the nutritional value of broiler diets containing approximately 35% soybean meal from insect-protected soybean containing CrylAc protein, or from a similar nontransgenic control, or from 7 reference commercial soybean varieties. The feeding trial lasted 41 d, and each treatment consisted of 10 replicates of 1-d-old Ross 508 broilers (5 pens males and 5 pens females). Each pen conta...

The effect of dietary lipids and Clostridium butyricum supplementation on circulating lipids and the transcription of selected genes involved in lipid metabolism were investigated in broiler chickens. One hundred and sixty-day-old broilers (Arbor Acres) were divided into four treatment groups in a 2 × 2 factorial arrangement and fed four diets with two lipid sources (soybean oil or fish oil) an...
