seed coat crude extracts of white-coloured ita-256, white and brown-coloured tvs-716, deep brown-coloured it-90k and light brown-coloured ife brown cowpea varieties were analyzed for the presence and amount of total phenol, tannin and flavonoid content. crude extracts of the cowpea varieties were analyzed for antioxidant activity using the thiobarbituric acid (tba) assay. the seed coat extracts...

A cross-sectional study was performed to estimate the prevalence of Salmonella on retail market chicken carcasses in Colombia. A total of 1,003 broiler chicken carcasses from 23 departments (one city per department) were collected via a stratified sampling method. Carcass rinses were tested for the presence of Salmonella by conventional culture methods. Salmonella strains were isolated from 27...

The present study was conducted to describe the effects of quercetin dietary supplementation, at levels of 0.5 and 1 g/kg of feed, on growth performance, internal organ weights, meat quality, and meat oxidative stability during storage of broiler chickens reared from hatching to 42 d of age. Body weight and cumulative feed intake were not affected by quercetin supplementation (P > 0.05). Howeve...

To elucidate the relationship between the arachidonic acid (AA) content and the taste of broiler meat, the effects of AA-enriched oil (AAO) supplements on the fatty acid content and sensory perceptions of thigh meat were evaluated. Four types of oil, including corn oil (CO), a 1:1 mixture of AAO and palm oil (PO) (1/2 AAO), a 1:3 mixture of AAO and PO (1/4 AAO), and a 1:7 mixture of AAO and PO ...

From 1997 to 1999, the prevalence of Salmonella was assessed at different stages through the pork, poultry, and beef meat production chains. Different dilutions of the initial sample suspension were analyzed to provide a semiquantitative evaluation of Salmonella contamination and to determine the most representative dilution necessary to detect a reduction in prevalence. An average of 300 sampl...

An experiment was conducted to determine the effect of lycopene on lipid profile and quality of meat of broiler chickens Ross 308 at a different form of selenium. 540 broiler cockerels were randomly divided into 6 groups: without lycopene supplement (groups C and E3), supplemented with 50 mg/kg lycopene (groups E1 and E4), supplemented with 100 mg/kg lycopene (groups E2 and E5) while the source...

This study was conducted to compare growth performance, carcass characteristics and meat quality of 4 breeds of local chicken. A total of 480 1-d-old chicks were distributed to 16 pens, with 4 treatments of breed, 4 replicates and 30 chicks per pen. Three Korean local breeds of white-mini broiler, Hanhyup-3-ho, and Woorimatdag, and a breed of silky fowl were raised under identical rearing and f...

The poultry industry has an important roll to supply food production by livestock protein in developing countries including Iran. The major sections in poultry production in Iran consists of broiler and laying production, broiler and laying breeder production, hatchery and line breeder production. Commercial productions in Iran have changed more or less during 1999-2003. The number of farms for...

Survival of Campylobacter jejuni and Campylobacter coli isolated from broiler meat was investigated and modeled on retail breast meat. Meat portions were inoculated with C. jejuni or C. coli at 6.4 to 6.8 log CFU/g followed by storage at 220uC for 84 days or at 4 or 12uC for 14 days. Kinetic data within a species and temperature were fitted to the Weibull model. When $70% of the residuals were ...

The objective of the current study was to evaluate the effect of dietary fat type and level on broiler meat quality. A 2 × 3 factorial arrangement with 2 types of fat including neutralized sunflower soapstock (NSS) and soybean oil (SO) at 3 levels of fat inclusion (2, 4, and 6%) was used with 5 replicates per treatment using 750 one-day-old broiler chicks in a completely randomized design. At t...
