Resumo: Nineteen adult goats of the Blanca Celtibérica breed - in non productive stage - from the experimental flock of Servicio de Investigación Agraria (Diputación General de Aragón) were scored using the lumbar, breast and tail palpation. Sternal triangle joint, lumbar square jointt a ailn tdha t were handled to assess body condition scores were dissected into muscle, bone subcutaneous fat and intermuscular fat. Regression analyses were developed for predicting carcass and body fat depots, using sternal triangle, lumbar square joint and tail compositions like independent variables. The best predictor of omental fat, subcutaneous fat, intermuscular fat, kidney fat, total body and total carcass fat depots was the totaol ff alut mbar square joint. On the other hand8 9, 80 and 86% (PS0,Ol) of the variationo f mesenteric, heart and udder fat depots, respectively, were accounted for by variation in intermuscular fat of sternal triangle joint. Finally, the subcutaneous fat weight of 1 tail vertebra accounted for 96% of the total variation of tail fat weight. In conclusion, the best predictor of the most important carcass and body fat depots (omental, subcutaneous, intermuscular, kidney, total body and total carcass fat) was the total fat of lumbar square. Utilisation de trois points de prélèvement comme prédicteurs des dépôts adipeux de la carcasse et du corps chez des chèvres de race Blanca Celtibérica". Un lot de 19 chèvres adultes de race Blanca Celtibérica, vides et taries, appartenant au troupeau expérimental du Service de la Recherche Agronomique (Gouvernement Autonome d'Aragon), ont été notées par la palpation au niveau lombaire, setet crnaauld al. Le triangle sternal, le carré lombaire et la queue ont été soumis à dissection en muscle, os, gras sous-cutané et intermusculaire. L 'analyse des régressionsé até utilisée pour prédire les dépôts adipeux de la carcaests edu corps de l'animal moyennant l'utilisation de la composition du triangle sterna/, du carré lombaire et de la queue comme variables indépendantes. Le meilleur prédicteur des graisses omentales, sous-cutanées, intermusculaires, rénales totales du corps, et totales de la carcasse é até le gras total du carré lombaire. D'autre part, 89, e8t0 8 6% (E0,Ol) de la variation des dépôts de gras mésentérique, du coeur et de la mamelle respectivement, ont eté expliqués par la variation du gras intermusculaire du triangle sternal. Comme conclusion, le meilleur prédicteur des dépôts adipeux de la carcasse et du corps les plus importants (omental, sous-cutané, intermusculaire, rénal, total du corps et total de la carcasse) a été le gras total du carré lombaire.
