          Abstract

          Se estudio el efecto del peso vivo al sacrificio y del sexo sobre las características de la canal del cordero lactante del cruce Suffolk Down x Merino Precoz Alemán. Las variables cuantificadas fueron: peso canal caliente (PCC), longitud de la canal (LC), rendimiento comercial (RC) y verdadero (RV), área del Longissimus dorsi (ALD), espesor de grasa dorsal (EGD), peso de componentes corporales (PCCO), y rendimiento al trozado comercial (RTC). Se utilizaron 30 corderos (15 machos y 15 hembras) sacrificados a 2 pesos vivos: 10 kg (7 machos y 7 hembras) y 15 kg (8 machos y 8 hembras). Los resultados se analizaron considerando los dos pesos de sacrificio (10 y 15 kg), sexo y la interacción entre ellos. El PCC, LC, ALD y EGD fueron superiores en los animales sacrificados a los 15 kg (P<0,05). Se observó una tendencia hacia un mayor RTC para los cortes pierna, espalda y chuletas, aunque no se observó ningún efecto significativo de los considerados, ni por la interacción (P>0,05). Considerando los resultados obtenidos se puede afirmar que el cruce Suffolk Down x Merino Precoz Alemán, sacrificado a un peso vivo de 10 y 15 kg, presenta excelentes características para la producción de carne.

          Translated abstract

          The carcasses of thirty suckling lambs (Suffolk Down x German Merino Precocius) were studied to estimate the effect of sex and slaughter weight on: hot carcass weight, carcass length, commercial and true dressing percentages, ribeye area, dorsal fat thickness, body components weight, and retail yield. The results were analysed considering two slaughter weights (10 and 15 kg), sex, and their interaction. Hot carcass weight, carcass length, ribeye area, and dorsal fat thickness were affected by slaughter weight. Leg, shoulder, and chops, showed the highest commercial yields and were not affected by sex, slaughter weight, nor their interaction. Based on these results it can be said that this genotype has excellent qualities for meat production.
