Two groups of six dry goats were allocated in metabolic cages for two weeks. Group P was fed with alfalfa hay and 4 different types of concentrate (barley, sugar beet pulps, broad-beans and chick-peas). In group S chick-peas were substituted by soya-beans. All feeds were free-choice offered. Goats selected a diet with variable proportions of sugar beet pulps and proteic concentrates, but with the same quantities of alfalfa hay and barley. In spite of the different behaviour, the nutrient content in the diet was very similar. The crude protein (CP) content was 12.5 per cent in group P and 13.0 per cent in group S, the neutral detergent fibre (NDF) content was 39.9 and 41.7 per cent respectively, and crude fibre (CF) 15.1 and 15.3 per cent. The proportion of feeds chosen by goats does not seem to be at random but oriented towards the achievement of optimal nutrient intake.
