This study examined the effect of CLA, flaxseed oil and fish oil and their combination forms on crude fat of liver and fatty acid profiles of liver, breast and thigh meat in broiler chicks. A total of 72, 1-day-old Cobb broilers were assigned to 6 groups, and fed an experimental diet supplemented with 5 different fat sources; conjugated linoleic acid (2% CLA), flaxseed oil (2% FXO), fish oil (2...

Experiments were conducted to evaluate digestible (dig) Lys requirements of male and female broiler chickens from 49 to 63 d of age. A dose-response diet consisting of corn, soybean meal, and corn gluten meal was formulated to be adequate in dig amino acid concentrations with the exception of Lys. L-Lysine . HCl was added to the dose-response diet to create 7 experimental diets. Concentrations ...

A total of three experiments were conducted to compare physical and microbiological properties of raw and marinated broiler breast fillets selected as being either lighter or darker than normal. Visibly light- and dark-colored breast fillets were divided into marinated and control groups, and vacuum-tumbled for 20 min at 4 C under 80 kPa pressure. Breast fillets from the four treatment groups w...

Lead contamination of seabirds from the use of lead shot in Greenland was studied in thick-billed murre hunted at Nuuk in November 1998. In each bird shot pellets were located and counted using X-ray. The birds were skinned and viscera, head, wings and legs removed, after which the carcass was cooked. The soup and breast meat were then analyzed for lead after removal of visible shot pellets. In...

1. Investigations were made into the breast and leg muscle energy metabolism, and the quality of breast meat of turkeys after controlled atmosphere stunning or stun-killing (CAS) with various gas mixtures. In addition, the effect on meat quality of an increase in the chilling rate of turkey breast meat after hypercapnic or anoxic stun-killing was studied. 2. A total of 35 turkey toms within t...

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 chemical composition of the meat from various cuts of poultry obtained from three commercial brands (brand I, II and III) of chicken from different processing plants available in the Saudi Arabian market were studied. Six raw meat samples of whole chicken and mixed portions (Breast fillet with skin, breast fillet without skin, drumsticks with skin, thigh cut skin on bone in and wings with s...

The relationship between diet and breast cancer is uncertain. We assessed the relationship of 4 common dietary patterns to the risk of breast cancer using the UK Women’s Cohort Study (UKWCS). A total of 35,372 women aged between 35 to 69 yr were recruited from 1995 to 1998. The UKWCS was selected to have a wide range of dietary intakes; 28% were self-reported vegetarian. Diet was assessed at ba...

Dalle Zotte A., Tasoniero G., Puolanne E., Remignon H., Cecchinato M., Catelli E., Cullere M. (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 ...

Introduction L* value (lightness) and pH have been used as predictive tools for estimating meat quality. In general, measurement of L* value is easier and faster than pH. Woelfel et al. (2002) reported that L* value seems to be of more predictive value than pH. Broiler meat with low pH or high L* value has been associated with low water-holding capacity, which results in increased cooking loss ...
