Assessment of goat fat depots using ultrasound technology and multiple multivar...
Peres, António M.; Dias, L.G.; Joy, M.; Teixeira, A.Assessment of fat depots for several goat body parts is an expensive and time-consuming task requiring a trained technician. Therefore, the establishment of models to predict fat depots based on data requiring simpler and easier procedures, such as ultrasound measurements, that could be carried out in vivo, would be a major advantage. An interesting alternative to the use of multiple linear regression models is...
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...
Estimation of light lamb carcass composition by in vivo real-time ultrasonograp...
Ripoll, G.; Joy, M.; Álvarez-Rodríguez, J.; Sanz, B.; Teixeira, A.The objectives of this study were to study the relationship between in vivo ultrasound measurements and cold carcass measurements at 4 anatomical points of the backbone, and to establish regression equations to estimate carcass composition within the cold carcass weight range for Ternasco lambs (8 to 12.5 kg) by using ultrasonic measurements taken at a single location. Measurements of subcutaneous fat and skin ...
In vivo estimation of goat carcass composition and body fat partition by real-t...
Teixeira, A.; Joy, M.; Delfa, R.The accuracy of ultrasound measurements to assess goat carcass composition and the partition of body fat depots was evaluated. An ultrasound machine with a 5-MHz probe and image analysis was used to assess in vivo fat thickness and muscle depth in 56 Spanish Celtiberica adult goats, in lumbar and breast body regions. The goats were slaughtered and the weight of body fat depots recorded. Measurements correspondi...
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...
Subjective measurements of fat cover and kidney knob and channel fat for predic...
Delfa, R.; Panea, B.; Joy, M.; Jiménez Badillo, M.R.; Teixeira, A.CCW, the assess of FC on two scores (1-5) and (1-15) and the assess of KKCF amount on two scores (1-3) and (1-9) were used as predictors of leg and rib tissue composition of 31 Blanca Celtibérica kids, with an average CCW of 6,9± 2,1 Kg. Proportionately 97% of the variation in muscle weight was accounted for by variation in CCW and the inclusion of KKCF amount scored from 1 to 9 improve the precision of the pr...

Delfa, R.; Joy, M.; Panea, B.; Jiménez Badillo, M.R.; Teixeira, A.CCW, the assess of FC on two scores (1-5) and (1-15) and the assess of KKCF amount on two scores (1-3) and (1-9) were used as predictors of shoulder, neck and flank plus breast tissue composition of 31 Blanca Celtibérica kids, with an average CCW of 6,9± 2,1 Kg. Proportionately 97, 91 and 92% of the variation in muscle weight of shoulder, neck and flank plus breast, respectively were accounted for by variation...
