Resumo: | The objectives of this study were to determine the association between carcass traits and the percentage yield in boneless cuts (PDC), bone, and fat trimmings of water buffalves; and to develop predicted equations for these variables. Forty-eight crossbred Murrah-Mediterránea buffaloes (24 steers and 24 bulls) were used slaughtered at 17, 19 and 24 months. Carcass and retail-yield-cut traits were evaluated. The following analyses were made: descriptive test, correlation, residual and multiple lineal regression. In castrated animals, subcutaneous fat and circumference round explained the majority of the variation in PDC. The dorsal fat thickness and the renal fat were the variables mostly associated with bone yield. In bulls, the subcutaneous fat and the carcass length explained most of the variation of PDC. The fat trimmings showed the highest correlation coefficient with the subcutaneous fat, and the bone yield was most correlated with the conformation. The equations obtained explained more than 50% of the variation in PCD, however equations for bone yield and fat trimmings showed a higher R2. |

Se utilizaron 48 búfalos de agua (24 castrados y 24 enteros), sacrificados a los 17, 19 y 24 meses de edad con mestizaje de razas Murrah y Mediterránea. Se evaluaron las variables de la canal y del rendimiento en cortes. Se realizaron: pruebas descriptivas, análisis de correlación, residuos y de regresión lineal múltiple. En los castrados, el acabado de grasa y la circunferencia del muslo explicaron la mayor variación en RCD. El espesor de grasa y el porcentaje de grasa renal fueron las variables mayormente asociadas con el rendimiento en hueso. En los enteros, el acabado de grasa y la longitud de la canal explicaron la mayor variación en RCD. El recorte de grasa se asoció más con acabado de grasa, y el rendimiento en hueso se asoció con la conformación. Las ecuaciones obtenidas lograron explicar más del 50% de la variación del RCD. Las ecuaciones para recorte de grasa y rendimiento en hueso tuvieron mayor fuerza predictiva.The objectives of this study were to determine the association between carcass traits and the percentage yield in boneless cuts (PDC), bone, and fat trimmings of water buffalves; and to develop predicted equations for these variables.
