Background and Aims: Enteric diseases have had detrimental impacts on commercial poultry through depressing growth rates and caused considerable economic losses to poultry producers. Chicken astrovirus (CAstV) is one of the most common viruses related to enteric diseases in chickens, especially in young chicks. Materials and Methods: Chicken astroviruses were detected by reverse transcriptase ...

The efficacy of probiotics as alternatives to antibiotics has been defined as one of the potential strategies to prevent Salmonella spp. infection in poultry. The purpose of this study was to isolate probiotic native Lactic acid bacteria (LAB) with high compatibility to intestinal tract and prevention of Salmonella typhimuriumfrom broiler chicken feces. Thirty-seven samples of...

Considerable savings can be realized and performance can be improved by formulating poultry feeds based on the daily feed intake and nutrient needs of the chicken. Programmes have been developed for commercial layers, broiler breeders, and replacement pullets for commercial egg production. Programmes have also been suggested for broiler breeder replacements for this purpose. Suggestions have be...

Mycoplasma synoviae (M. synoviae) is a major worldwide poultry pathogen that causes serious economic losses in the poultry industry. This study was designed to detect M. synoviae through culture isolation and polymerase chain reaction (PCR) assay to demonstrated the involvement of M. synoviae infection in trachea and the lung/air sac samples taken from commercial broiler chicken farms in 3 m...

Data from a large commercial-scale experiment in which 10 major broiler producer companies stocked whole houses of birds at 30, 34, 38, 42, and 46 kg/m2 were analyzed to identify 1) temperature and humidity profiles achieved throughout the growth cycle, 2) management practices and equipment that contributed to observed variation in environmental conditions, and 3) the extent to which environmen...

Avian pathogenic Escherichia coli (APEC) bacteria are a significant challenge to the poultry industry. Bacteriophages (phages) have the potential to control APEC strains, increasing animal welfare and economic productivity. Here, we report the isolation of an E. coli-infecting phage, APC_JM3.2, isolated from the cecum of a broiler chicken in Ireland.

Co-products from distillation of cereal grains for alcohol production have been available to poultry and livestock producers for many years. Although the co-products were considered better suited for ruminants because of their relatively high fiber content, Morrison (1954) suggested that chick diets could contain up to 7% or 8% distillers grains and that diets for laying hens could contain up t...

A free-range broiler breeder flock was studied in order to determine the natural patterns of Campylobacter colonization over a period of 63 weeks. Campylobacter sequence types (STs) were not mutually exclusive and on average colonized only 17.7% of the birds tested at any time. Campylobacter STs typically reached a peak in prevalence upon initial detection in the flock before tailing off, altho...

1. Studies on the sensory profiling of male broiler breast meat were carried out to evaluate the effect of two very different broiler breeds (JA757 and New Hampshire), two different feed types (broiler and grower feed) and age at slaughter (82 and 110 d). 2. The sensory profiling consisted of a pilot study, 4 training sessions, and finally the assessment. During the training session a panel of ...
