This experiment evaluates the effect of decreasing dietary CP, in addition to the effects of dietary supplements of L-Thr to low CP diets, in Large White Nicholas toms from 0 to 18 wk of age. Toms were fed dietary treatments consisting of four levels of dietary CP as a percentage of NRC (1994) recommendations (100, 92, 84, and 76% of NRC recommendations). Additional treatments consisted of supp...

The present study was conducted to analyze the physico-chemical and colour properties of emu meat. The leg, back and breast portion along with a uniform mix of these three cuts were taken for evaluation of emu meat quality in respect to various physico-chemical parameters. The pH of breast meat was found significantly (P<0.05) lower than meat from leg and back portion. Water holding capacity of...

The objective of the study was to compare the carcass characteristics, meat quality, and blood parameters of slow and fast grown female broiler chickens fed in organic or conventional production system. The two genotypes tested were medium slow-growing chickens (SG, Hubbard Red JA) and commercial fast-growing chickens (FG, Ross 308). Both genotypes (each represented by 400 chickens) were divide...

(2017): Effect of “Wooden Breast” appearance on poultry meat quality, histological traits, and lesions characterization. Czech J. Anim. Sci., 62, 51–57. The purposes of the study were to investigate the effects of Wooden Breast (WB) myodegeneration on poultry meat quality and to give a contribution in ...

The structural and metabolic characteristics of the pectoralis major (P. major) muscle (i.e., breast muscle) and the quality of the resulting meat were studied in relation to breast muscle fiber development in broiler chickens. Six hundred birds originating from a commercial, grand parental, male heavy line (Hubbard-Europe, Châteaubourg, France) were kept under conventional breeding methods unt...

The Thr needs in 3 commercial broiler strains (A, multipurpose; B, high yield; C, high yield) known to differ in terms of feed intake, growth rate, and breast yield were evaluated. Birds were randomized across 96 floor pens (12 birds/pen), received a common diet from d 1 to 20, and were fed graduations of Thr (0.52 to 0.87% total Thr in 0.07% increments) from d 21 to 42. Treatments (3 x 6 facto...

Several factors may affect poultry breast meat quality, both intrinsic characteristics (age, sex, size and strain) and external influences (carcass aging time postmortem before deboning, fillet marination and cooking method). Commercial duck processors are now expanding into the deboned breast meat markets but very little research is available on duck meat quality as compared to other poultry s...

The feeding value of extruded and nonextruded wheat and corn distillers dried grains with solubles (DDGS) for broilers was evaluated in 2 experiments. In experiment 1, male broilers (n=360) housed in battery cages were fed assay diets that included either 15 or 30% wheat or corn DDGS (extruded or not) in relation to a basal diet from d 21 to 28. Birds were killed on d 28 and ileal digesta was c...

Previous research has indicated that seasonal-type heat stress (HS) can contribute to the development of pale, soft, exudative (PSE) meat in fast-growing turkeys and that halothane exposure may identify stress-susceptible animals. This study evaluated the ability of halothane screening to identify stress-susceptible birds prone to developing pale, exudative meat when reared to market age. Two l...

a total of 240 japanese quail chicks (1 d old) were used in a 42-d trial to study the effects of artichoke leaf powder and vitamin e on growth performance and meat quality. this experiment was performed as a completely randomized design with 4 replicates of 15 quails in each, using a 4×2 factorial arrangement with diet and gender as the main effects. four dietary treatments were formulated by a...
