PENALOZA A., Fernando; SAN MARTIN H., Felipe  y  ARA G., Miguel. Valor nutricional de la algarroba (Prosopis pallida) en la alimentación del caballo. Rev. investig. vet. Perú [online]. 2002, vol.13, n.1, pp.17-24. ISSN 1609-9117.

The present research was carried out to estimate the nutritional value of carob bean (Prosopis pallida) in horses. Four rations with increasing carob bean levels (0; 20: 46.7 y 66.7%) in a base-diet of barley and lucerne hay were evaluated. Four Anglo-Argentinien crossbred geldings were fed the four rations using a simple overchange model with an arrangement of the 4 x 4 Latin Square. A feeding-test consisting of lucerne hay alone was previously done, aiming at obtaining digestibility of carob bean by difference in percentage with the treatment containing 66.77% carob bean. Digestibility of both dry and organic matter was 62.1% and 61.6%, respectively. The increase of carob bean's content in rations reduced digestibility in most nutritional fractions of feeding rations, with the exception of ethereal extract. Reduction followed a linear, significant pattern (P<0.05) for organic matter, nitrogen-free extract, neutral detergent fibre and acid detergent fibre.
