Effect of deboning time on the quality of broiler breast meat (Pectoralis major)

In this study the carcass and quality (nutritive, technological and sensory) of broiler breast meat were analysed. Hubbard chickens were used for investigations (n=200). There were two groups of samples: control group (C) chickens fed with standard mixture, and experimental group (E) chickens fed with standard feed mixture supplemented with 2% of garlic powder. The trial lasted 42 days. Experimental group had higher (p<0.05) meat yield in chickens breast, but significant effect of garlic addition on nutritive quality of chicken breast meat were not noted. In the breast meat of the experimental group E significantly (P < 0.05) higher protein content and lower (P < 0.05) fat content, compared to control (C), was found. Cholesterol levels in breast meat of the experimental group E (46.1 mg/100g) was significantly lower (P < 0.05) compared to the control group (60.1 mg/100g). The average technological quality of breast meat of groups regarding to pHk, as the parameter and criteria for determining the quality of breast meat corresponds to PSE. The average technological quality of breast meat of control and experimental group according to colouru (L*), as the parameter and criteria for determining the quality of breast meat, corresponds to “normal quality”. According to results of sensory analyzes, roasted breast meat of the experimental group had significantly (P < 0.01) preferable juiciness and tenderness.

Broiler Breast

The objective of this work was to investigate the effect of road transportation conditions on the occurrence of broiler PSE-(Pale, Soft, Exudative) and DFD-like (Dark, Firm, Dry) meats in the Brazilian commercial slaughterhouse plant. Samples of Pectoralis major m from 47-day-old broilers of commercial lineage were analyzed. The results indicated that water-bathing birds just before journey over 3.0km promoted the occurrence of 46.0% of PSE and 4.0% of DFD-like meat, while birds under non-water bathing conditions presented 14.7 and 2.0%, respectively. For a distance of 68.0km, the occurrences of PSE-and DFD-like meat were 44.0 and 0.0% under water bathing conditions, and 52.0 and 0.0% without water bathing, respectively. Water bathing at the farm was a critical manoeuvre for increasing the unfavourable truck microenvironment for short journey, whereas conversely for longer journey it was less stressful influencing the broiler breast meat quality.
