Objective Evaluate the effects of i) dehulling of lupine seed on chemical composition and apparent metabolizable energy (AME) and ii) soybean meal substitution by dehulled lupine seed in broiler diets with enzymes on productive performance, size of digestive organs and welfare-related variables. Methods Experiment 1, chemical composition and AME were determined in whole and dehulled lupine seed. Experiment 2, two hundred eighty-eight one-day-old male Ross 308 broilers were used. The experimental diets were maize-soybean meal (MS), MS with enzymes (MSE) and maize-dehulled lupine seed with enzymes (MLE). Diets were assigned to the experimental units under a completely randomized design (eight replicates per diet). The body weight (BW) gain, feed intake, feed conversion, digestive organ weights, gait score, latency to lie down and valgus/varus angulation were evaluated. Results The dehulling process increased protein (25.0% to 31.1%), AME (5.9 to 8.8 MJ/kg) and amino acid contents. The BW gain of broilers fed the MLE diet was similar (p>0.05) to that of those fed the MS diet, but lower than that of those fed the MSE diet. Feed intake of broilers fed the MLE diet was higher (p0.05) to those fed the MSE diet. Feed conversion of broilers fed the MLE diet was 8.0% and 8.7% higher (p

Resumen basado en el que aporta la revista. Interdisciplinariedad, segregación pedagógica, constructivismo e investigación-acción son los cuatro pilares sobre los que se fundamenta la implementación del Proyecto Arianne en un instituto canario. Se describe con detalle las distintas fases de trabajo puestas en marcha y concede especial progatonimos a la investigación realizada sobre las ideologías de chicos y chicas. Las conclusiones extraídas tras la conversación de tres grupos de adolescentes sirven para diseñar un modelo específico de intervención educativa.. Cataluña ESP
