Rendimiento de la canal en búfalos de río (Bubalus bubalis) y Bovinos mestizos (Bos indicus x Bos taurus) en el Municipio Bayazo - Canal performance in river buffaloes (Bubalus bubalis) and mixed racial bovines (Bos indicus x Bos taurus) in the Bayamo Municipality

Resumen
Con el objetivo de determinar algunas características de rendimiento en canales bufalinas (Bubalus bubalis) de animales procedentes del Centro de Ceba El Progreso y compararlas con canales vacunas (Bos indicus x Bos taurus) comercializadas, se desarrolló esta investigación en el matadero Jucaibama. Se trabajaron 60 animales enteros de cada especie con edades entre 24 y 32 meses, a los cuales se les determinaron los siguientes parámetros: peso de embarque (Kg.) (PE), peso vivo reposo (PV) (Kg.) peso de la canal en kg. (PC),
rendimiento en carne en kg. (RC), rendimiento en carne de primera en Kg. (RC1) y rendimiento en carne de segunda en Kg. (RC2). Los resultados fueron para (PE) 543,43 y 489,92 arrojando el análisis diferencias altamente significativas, al igual que para las (PV) y (PC) que fueron de 527,12 y 474,15
271,52 y 244,83 para búfalos y vacunos respectivamente. Las variables (RC), (RC1) y (RC2) no mostraron diferencias significativas, sus valores fueron 167,37 y 171,93
88,7 y 91,12
76,66 y 78,74 para canales bubalinas y vacunas. Se concluye que los búfalos presentaron pesos mayores al sacrificio y de canal que los vacunos evaluados. El búfalo presentó mayores rendimientos en carne, parámetros que indican que tiene la posibilidad de desarrollar mayor masa muscular que sus competidores vacunos.
Summary
This research was carried out in the drudgery Jucaibama of determining some quality characteristics in the buffaloes meat (Bubalus bubalis) of animal that belong to the feeding place El Progreso. These characteristics are compare with the ones of the beef cattle (Bos indicus x taurus) that are commercialized. 60 whole male
animals of each species were taken as sample. They were about 24 and 32 months old and they were determine the following parameters: Shipment weight (Kg.), weight after twelve hours, meat weight, meat
servility and servility of the best showed highly significant differences, just as the ones for (PV) and (PC) whose results were 527,12 and 474,15
271,52 and 244,83 for buffaloes and beef cattle’s respectively. The variables (RC), (RC1) and (RC2) did not show significant differences. Their values were 167, 37 and 171, 93
88, 7
and 91, 12
76, 66 and 78, 74 for buffalo meat and beef cattle’s. The results were analyzed through the program STATISTIC version 6.1 for Windows, (2003). For the analysis of the data he was carried out by
means of the test of simple variances of Duncan (1955). A conclution was drawn and it was that the buffalo’s weight was higher by the time of the sacrifice as well as the buffalo meat as compared to the beef
cattle evaluated. The above-mentioned parameters indicate that the buffalo is more able to develop muscular mass than its beef cattle rival.
