The objective of this study was to compare the physicochemical and nutritional properties of breast and thigh meat from commercial Chinese crossbred chickens (817 Crossbred chicken, 817C), imported commercial broilers (Arbor Acres broiler, AAB), and commercial spent hens (Hyline Brown, HLB). The crossbred chickens, commercial broilers and spent hens were slaughtered at their typical market ages...

in poultry breeding, use of any antibiotics as a food additive that promotes growth, prevention or treatment of infectious diseases will increase the chance of drug residues in poultry meat products. in this study, the presence of different antibiotics in ten broiler flocks, which were later transported to mashhad poultry abattoir have been investigated, using four plate test (fpt) method. a to...

High intake of meat, particularly red and processed meat, has been associated with an increased risk of a number of common cancers such as breast, colorectum, and prostate in many epidemiological studies. Heterocyclic amines (HCAs) are a group of mutagenic compounds found in cooked meats, particularly well-done meats. HCAs are some of most potent mutagens detected using the Ames/salmonella test...

Selected parameters of quality (hydroxyproline, calcium, bone particles content, and histological determination of bone particles) of mechanically deboned poultry meat (MDPM -„firm separation“ and soft separation „Baader meat“) were compared. Comparison of results with composition (except bone particles) of fresh poultry meat (breast and thigh muscles) was performed. Hydroxyproline content was ...

This study is conducted to evaluate the effects of the mixing ratio between pork loin and chicken breast for textural and sensory properties of emulsion sausages. Meat homogenates are prepared by using five mixing ratios between pork loin and chicken breast (100:0, 70:30, 50:50, 30:70, and 0:100), and the emulsion sausages are also formulated with five mixing ratios. The additions of chicken br...

Aim The present study was conducted to explore the effect of supplementation of Withania somnifera and synbiotics alone or in combination on the composition of broiler breast meat under heat stress conditions. Materials and Methods A 42-day feeding trial was conducted on 360 broiler chicks randomly allotted into eight treatment groups with three replicates each under completely randomized des...

Male commercial broiler strain chickens were fed either a control diet (based on corn and soybean meal) or the control diet supplemented with cupric sulfate pentahydrate or cupric citrate in seven experiments (six in floor pens, one in wire-floored batteries). In Experiment 1, feeding 125 or 250 mg/kg copper increased growth (4.9%) and decreased feed conversion ratios (3.4%), total plasma chole...

2-amino-1-methyl-6-phenylimidazo[4,5-b]-pyridine (PhIP), the most abundant heterocyclic amine (HCA) in cooked food, is a mammary carcinogen in female rats. In humans, consumption of well-done meat and PhIP intake have been associated with an increased risk of breast cancer, but PhIP-DNA adducts have not been analyzed in breast tissues from women having unknown exposure to HCAs. Using an immunoh...

the objective of the present study was to determine the effects of feeding high levels of l-arginine on growth performance, blood metabolites, and carcass meat quality of female ross broiler chickens at the starter period. in this experiment, 192 day old chicks were fed with 4 dietary treatments (100%, 153%, 168% and 183% of digestible arginine, based on the ross catalogue recommendation) with ...

the present study was aimed to assess the influence of brown marine algae and vitamin e (ve) (160 ppm α-tocopheryl acetate) on stability of chicken meat enriched with fish oil. in this study, 360 d-old broilers (arbor acres plus) were randomly assigned to 6 treatment groups with 4 replicates of 15 birds in each. experimental groups consisted of corn-soybean basal diet (c), corn-soybean basal di...
