The bacterial succession on the skin of broiler chicken carcasses stored at 2 degrees C was traced, and the ability of representative isolates to produce off-odors was determined by using sterile leg and breast muscle sections. Off-odors were identified by olfactory and chemical means. The inability of peptone-iron agar to detect sulfide-producing strains was noted.
We conducted an observational study to estimate prevalence and risk factors for Salmonella spp. and Campylobacter spp. caecal colonization in poultry. Eighty-one broiler chicken and 59 turkey flocks selected among flocks slaughtered in the province of Quebec, Canada, were included in the study. Flock status was evaluated by culturing pooled caecal contents from about 30 birds per flock. Exposur...
Campylobacter jejuni and Campylobacter-specific bacteriophage were enumerated from broiler chicken ceca selected from 90 United Kingdom flocks (n = 205). C. jejuni counts in the presence of bacteriophage (mean log(10) 5.1 CFU/g) were associated with a significant (P < 0.001) reduction compared to samples with Campylobacter alone (mean log(10) 6.9 CFU/g).
This study was conducted to evaluate the carcass yield, abdominal fat deposition and chemical compositions of thigh and breast muscles of male Arian broilers fed three different lysine levels of 1) high lysine (110% NRC), 2) standard level suggested by National Research Council (NRC) and 3) low lysine (90% NRC) based on two expression ways of amino acid contents of feedstuffs, as total amino ac...
Feed is an important factor that influences the chicken's development and growth. Meanwhile, dalugha debris a by-product of processing which expected to be source feed for growth broiler chickens. The good can optimize metabolic processes in animal so it support process animal. This study aims determine levels hemoglobin, cholesterol, blood glucose chicken given supplementation. used completely...
this research was conducted to compare the effects of two medicinal plants (peppermint and aloe vera) and antibiotic growth promoter on ileum microflora population and growth performance of broiler chickens. in this experiment, 375 one-day old male broiler chickens (ross 308) were used on a completely randomized design with 5 dietary treatments which were replicated 5 times with 15 birds per re...
the effects of dietary vitamin e levels on mucosal maltase and alkaline phosphatase (alp) enzyme activities and on the amount of mucosal malonyldialdehyde (mda) in broiler chickens were studied in the present study. one hundred and eighty of day old male broiler chicks (ross 308 strain) were randomly assigned into five groups, each with three replicates and 12 chicks in each replicate. chickens...
this study was designed to investigate the effects of different levels of tarragon powder on performance, carcass characteristics of broiler chickens. two hundred ross 308 male broiler chickens were randomly allocated into four treatments and five replicates per treatment. at each replicate ten birds were used. experimental diets were set on the basis of corn-soy-wheat and ross 308 broiler chic...
ornithobacterium rhinotracheale (ort) is a bacterium associated with respiratory disease, growth retardation, decreased egg production and mortality in chickens and turkeys. the objective of this study was isolation, identification and evaluation of antimicrobial susceptibility of ort bacterium in slaughtered broilers chicken flocks based on cultural and molecular tests in khuzestan province, s...
Shiga toxin-producing Escherichia coli (STEC) are food-borne pathogens primarily associated with the consumption of contaminated ground beef and are an important food safety concern worldwide. STEC has been found to produce a family of related cytotoxins known as Shiga toxins (Stxs). Shiga toxins have been classified into two major classes, Stx1 and Stx2. A single strains of STEC can produce St...
