- Atlas de disección de la canal de los ruminantesPublication . Panea, Begoña; Ripoll, Guillermo; Alberti, P.; Joy, Margalida; Teixeira, AlfredoSe presenta un atlas para la disección de la canal de los rumiantes. El atlas se estructura en cuatro partes. En la primera parte se describe cómo preparar la canal de los pequeños rumiantes para su disección, la obtención de las diferentes piezas y la disección detallada de cada una de ellas. En la segunda parte se muestra cómo realizar la disección de una costilla de vacuno. En la tercera, se ofrecen los valores esperables para la composición de cada pieza, así como las fórmulas para calcular el porcentaje de cada tejido en la canal o la pieza. Por último, en la cuarta se ofrece una revisión bibliográfica a fin de que el investigador que se inicie en el tema pueda cotejar sus datos
- In vivo ultasonic measurements and live weight for predicting carcass quality in Churra Tensina mountain breed lambsPublication . Delfa, Rafael; Joy, Margalida; Sanz, Albina; Panea, Begoña; Álvarez-Rodríguez, Javier; Alberti, P.; Teixeira, AlfredoForty-six single male lambs ofChurra Tensina mountain breed with a live-weight ranging from 19.9 . to 24.4 kg ('Temasco' carcass commercial type) were scanned by ultrasound (ALOKAmodel SSD- 900, with a 7.5 MHz probe) to determine M. longissimus dorsi depth and subcutaneous fat thickness between the lOth-lith, 12th-13th dorsal vertebrae and 1st-2nd, 3rd-4th lumbar vertebrae. Lambs were slaughtered and carcasses were cooled at 4 °C for 24 h and halved. The left side was divided according to a standardised jointing procedure, based on six anatomical regions: shoulder, long leg, anterior ribs, ribs, flank and neck. Each joint was then disseCted into ,muscle, bone plus remainder and subcutaneous, inter-muscular, kidney and pelvic fat. Thein vivo ultrasound measureme~ts plus slaughter weight were fitted to predict carcass tissue composition by Stepwise regression analysis. All the developed models were highly significant (P
- Influence of production factors on the characteristics of meat from ruminants in Mediterranean areaPublication . Teixeira, Alfredo; Delfa, Rafael; Alberti, P.The production systems or cattle sheep and goats in Mediterranean area and the factors linked with carcass and meat quality are discussed. The production systems in the mountain and semi-arid areas, typical of Mediterranean, are refereed. Finally a group or actions to be taken regarding the improvement of meat production from ruminants is suggested.
