Resumo: Six ultrasonic fat and muscle depth measurements, taken on the left and the right side of the fourth lumbar vertebra and third stemebra of the breast bone, were related to carcass composition to determine the accuracy of these measurements for predicting carcass compositon of live Aragdn lambs (Temasco) . Live weight alone accounted for 21, 19,26, 18 and 47% of total variation of muscle, bone plus remainder, total fat, and subcutaneous and intermuscular fat, respectively. Addition of ultrasonic fat depth measurement on the right side of the lumbar region accounted for a further 18,31,33 and 36% of muscle, bone plus remainder, total carcass fat and subcutaneous fat, respectively. Addition of the same measurement taken on the left side accounted for a further 15% of intermuscular fat. Live weight alone accounted for only 4% of the total variation of kidney and pelvic fat, but the addition of ultrasonic fat depth measurement on breast bone accounted for a further 26% of the variation of this fat depot. The accuracy of prediction of carcass composition on live animals could be improved by the addition of ultrasonic fat measurements.

Le poids vif à lui seul a expliqué 21, 19, 26, 18 et 47% de la variation totale du muscle, de l'os plus les déchets, du gras total et du gras souscutané et intermusculaire, respectivement. L'addition des mesures d'épaisseur du gras (mesure C) réalisées par ultrasons sur le côté droit de la région lombaire, ont augmenté de 18, 31, 33 et 36% la précision de l'estimation de la variation totale du muscle, de l'os plus déchets, du gras total et sous-coutané de la carcasse, respectivement. L'addition de la même mesure réalisée sur le côté gauche a augmenté de 15% la précision de l'estimation de la variation totale du gras intermusculaire. Cependant, le poids vif n'a expliqué que 4% de la variation totale du gras pelvico-rénal, mais l'addition de la mesure d'épaisseur du gras sternal total, réalisée aux ultrasons, a augmenté de 26% la précision de l'estimation de la variation de ce dépôt adipeux. La précision de la prédiction de la composition de la carcasse sur l'animal vivant pourrait augmenter par l'addition de mesures de l'épaisseur du gras réalisées aux ultrasons.Un total de 6 medidas de espesor de grasa y músculo realizadas mediante la utilización de ultrasonidos sobre la 4a vertebra lumbar y la 3a esternebra del esternón fueron relacionadas con la composición de la canal, con el principal objetivo de estudiar la exactitud de estas medidas como predictoras de la composición de la canal de corderos vivos productores de ‘Ternasco de Aragón’. El peso vivo solo explicó el 21, 19, 26, 18 y 47% de la variación total del músculo, hueso más desechos, grasa total y grasa subcutanea e intermuscular respectivamente. La adición de las medidas de espesor de grasa (medida C) realizadas con ultrasonidos sobre el lado derecho de la región lumbar, incrementaron un 18, 31, 33 y 36% la precisión de la estimacón de la variación total del músculo, hueso más desechos, grasa total y subcutánea de la canal respectivamente. Y la adición de la misma medida realizada sobre el lado izquierdo incrementó un 15% la precisión en la estimación de la variación total de grasa intermuscular. Sin embargo el peso vivo solo explicó el 4% de la variación total de grasa pelvico-renal, pero la adición de la medida de espesor de grasa total del esternón realizada con untrasonidos, incrementó un 26% la precisión de la estimación de la variación de este depósito adiposo. La precisión de la predicción de la composición de la canal en el animal vivo podría ser incrementada con la adición de medidas del espesor de grasa realizadas con ultrasonidos.ElsevierBiblioteca Digital do IPBDelfa, RafaelTeixeira, AlfredoGonzález, C.Blasco, I.2008-09-09T16:20:35Z19951995-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10198/798engDelfa, R.; Teixeira, A.; González, C.; Blasco, I.
