In the modern broiler industry, solutions are still being sought to improve conditions or eliminate problems related to issues such as animal welfare, health, and meat quality brought by intensive production systems. Therefore, this experiment was conducted to study effects of perching on growth performance, carcass characteristics, and footpad lesions (FPLs) in broiler chickens. A total of 300...

the purpose of this study, was to evaluate the use of echinacea purpurea (ep) root as a feed additive in broiler chicken diets. 340 7-d-old male broilers (ross 308) were randomly allocated into 5 experimental treatments (with 4 replicates) including control diet without additive, experimental diet supplemented by flavophospholipol (fl) (650 ppm) and three experimental diets were supplemented by...

Genetic parameters of breast meat characteristics [pH 15 min postmortem (pH15min), ultimate pH (pHu), CIELAB color parameters (L*, lightness; a*, redness; b*, yellowness) and drip loss (DL)] as well as their genetic correlations with BW and body composition [breast yield (BRY) and abdominal fat percentage (AFP)] were estimated in an experimental meat-type chicken line. Heritability of the pH of...

The present study was aimed at evaluating the molecular mechanisms associated with the differences in muscle glycogen content and breast meat quality between 2 experimental lines of chicken divergently selected on abdominal fatness. The glycogen at death (estimated through the glycolytic potential) of the pectoralis major muscle and the quality of the resulting meat were estimated in the 2 line...

The goals of this research were to estimate the phenotypic relationship among various breat meat quality traits, blood parameters and tonic immobility from a broiler and to describe the relation among these variables. Broiler chicks were devided into different groups: (1) colour clothing groups represented four different colours as red, blue, green, and gray and (2) the chicks that were subject...

Objective: Epidemiologic data do not provide consistent evidence for an association between consumption of meat and breast cancer risk. We conducted a hospital-based case-control study during April and July 2010 among Iranian women to investigate associations between dietary meat intake, its types and breast cancer risk. Methods: One-hundred consecutively recruited cases with newly diagnosed br...

The aim of the present study was to investigate how a higher temperature at a comparable period during chicken incubation influences the muscle development and the meat quality in the animals post hatch. Therefore half of fertilized eggs of the broiler genetic Cobb were incubated between ED 7 to 10 at 38.5 °C instead of 37.5 °C (control group). At the day of hatch (Day 21) the hatch rate was 86...

Four experiments were conducted to determine the effects of electrical stunning and decapitation on bird activity as well as carcass and meat quality. In Experiment 1, broilers were subjected to one of four stunning and killing methods: no stun and neck cut, stun and neck cut, no stun and decapitation, and stun and decapitation. Birds were scored for severity of physical activity on a scale of ...
