    Hace ya tres décadas que Ottavio di Camilo señalaba: «De De Alonso Ortiz y de sus actividades humanísticas se sabe muy poco. Dejó su biblioteca (más de seiscientos tomos, según Bertini, y más de mil según Beltrán de Heredia) a la Universidad de Salamancast. Esta afirmación e incluso falta de concreción, como se observa en lo que respecta a la donación de libros que este Canónigo de Toledo hizo al Estudio salrnantinot, puede ampliarse, por desgracia, hasta nuestros días; pues de hecho pocas son las referencias que se tienen de su labor de traductor-, máxime cuando no se ha llegado a subrayar todavía que él es el transladador dela primera traducción castellana impresa de las Meditaciones de San Anselmo

    Experimental balance to estimate efficiency in the use of nitrogen in rabbit breeding

    [EN] Defining the composition and properties of manure in livestock production is critical in order to minimise possible environmental impacts stemming from its management. In this study, a nitrogen balance was carried out during two identical fattening periods (Experiments 1 and 2) in growing rabbits from weaning (age 28 d and live weight about 0.6 kg) to slaughter (age 61 d and live weight about 1.8 kg). The breeding conditions were typical for Spanish rabbit production. The objectives were to quantify the total nitrogen excreted by the animals and to estimate the average efficiency in the use of this nutrient, in comparison to other species. Animal weight, feed intake, and the production of faeces and urine were monitored weekly in a set of eight cages with nine rabbits in each, performing weekly analyses for nitrogen content in feed, urine and faeces. The overall nitrogen excretion was 50.2 g N per animal in Experiment 1 and 46.9 g N per animal in Experiment 2, which corresponded to about 58% of the total nitrogen intake. Urine and faeces contributed to overall nitrogen excretion in approximately the same proportions. The nitrogen excretion ratio was 40 grams per kilogram of animal produced. According to this ratio, rabbit breeding is less efficient in the use of nitrogen than raising broilers, but more than fattening pigs.The authors thank the Spanish Ministry of Education and Science for the economic support to conduct this study (Project GASFARM AGL2005-07297).Calvet Sanz, S.; Estellés Barber, F.; Hermida, B.; Blumetto, O.; Torres Salvador, AG.
