Development of organs and tissues in lambs raised on Spanish mountain grassland
Álvarez-Rodríguez, J.; Sanz, A.; Joy, M.; Carrasco, S.; Ripoll, G.; Teixeira, A.The present study was conducted to establish the pattern of body development in grass-raised Churra Tensina lambs. Forty-nine single male lambs were slaughtered at three body-weight intervals, according to the commercial categories of suckling (11.191.0kg), light (22.190.8 kg) and heavy lamb (32.092.9 kg). Non-carcass and carcass components were recorded and the half left carcasses were completely dissected. La...
Estimación de la composición de la canal de ternasco por ultrasonidos en canal
Ripoll, G.; Álvarez-Rodríguez, J.; Sanz, A.; Teixeira, A.; Joy, M.Se sacrificaron 129 corderos tipo Ternasco de las razas Churra Tensina y Rasa Aragonesa a un peso vivo entre 22 y 24 kg. Se midieron los espesores de grasa subcutánea y el ancho y profundidad del músculo en la 10ª vértebra torácica a tres distancias de la línea media dorsal por medio de ultrasonidos en la canal caliente. Estas mismas medidas se realizaron con calibre en la canal fría y se realizó la disección e...
In vivo ultrasonic measurements and live weight for predicting carcass quality ...
Delfa, R.; Joy, M.; Sanz, A.; Panea, B.; Teixeira, A.Forty six single male lambs of Churra Tensina mountain breed with a live weight ranging from 19.9 to 24.4 Kg producers of carcass type Temasco, were scanned by ultrasound (ALOKA model SSD-900, with a 7.5 MHz sounder) to determine M. Longissimus dorsi depth and subcutaneous fat thickness between the I Olh_l ]lh, 12th_13th dorsal vertebra and PI_2nd, 3rd_4lh lumbar vertebra. Lambs were slaughtered after 24 h. fas...
