The carcass traits, carcass nutrient composition, amino acid, fatty acid, and cholesterol contents of local Turkish goose varieties reared in an extensive production system

Abstract

This study was performed to determine the slaughter and carcass traits, meat color, pH, nutrient composition, fatty acids, amino acids, and cholesterol content of local Turkish goose varieties. In the present study, a total of 80 geese from white, black, gray, and multicolored varieties were reared in an extensive production system at 28 wk of age. Quality analysis was performed on breast and thigh meat, as well as on the skin and abdominal fat of studied geese. Slaughter and carcass weights were significantly higher in the white variety (P < 0.01). Measured abdominal fat was lower in black and gray geese. Furthermore, the color and pH values were significantly different on breast, thigh, and skin among varieties. Additionally, measured breast meat b*, thigh meat L*, and b* values were higher in male geese. Breast meat protein levels were lower in black and gray geese, and also lower in the thigh meat of gray geese. Total breast meat amino acids were lower in white geese, and the amino acid content of thigh meat was lower in multicolored varieties. Moreover, differences in fatty acid composition were found among the studied varieties. However, cholesterol levels did not differ for either sex or variety.
