Abstract

Our objective was to evaluate carcass traits and meat quality of quails from different strains and both sexes pertaining to three breeding-improvement programs. Quails from seven meat-type strains (UFV1, UFV2, UFV3, EV1, EV2, LF1 and LF2) and from one egg-laying (Japanese quail) strain (LAY) were slaughtered at 35 days of age. A completely randomised 8 (strain) × 2 (sex) factorial design was used for data analysis. Bodyweight, hot carcass weight and breast (musculus pectoralis major and m. pectoralis minor) and legs (thigh and drumstick) weights and their respective yields were determined. Ultimate pH, colour measurements, water-holding capacity, cooking loss and shear force were assessed. No difference in ultimate pH, shear force and hue was observed. The UFV3 strain had the greatest bodyweight at slaughter. The UFV3 strain had the greatest hot carcass weight in both sexes. The heaviest breasts were observed in both sexes of the UFV3 strain and in males of the UFV2 strain. The UFV3 quails had greater leg weight. The hot carcass yields of meat-type strains were greater than that of the LAY strain. The UFV3 and LAY females furnished a greater breast yield than did male quails. For males, the UFV1 strain had a greater yield of breast than that of LAY quails. The LAY quails presented the greatest yields of leg. The LAY quails had the least luminance, and the greatest water-holding capacity, cooking loss, red and yellow intensity, and chroma. In summary, meat obtained from meat-type strains had a greater water-holding capacity, lower cooking loss and greater luminance than that of the LAY strain. In addition, the meat-type strains grew appreciably faster, but the difference in yields of breast and leg meat between meat and layer strains was small. We conclude that meat-type strains, especially the UFV3, are more appropriate for enterprises focussed on meat production.
