A total of 22 surveys reveals that the diets of goat flocks in the Murcia Region (Spain) are imbalance and vary greatly from one farm to another. In order to calculate the optimum diets (balanced and least expensive), the CIDA (Agro-Food Research and Development Centre) in La Alberca, Murcia, is implementing a Guidance Project, which consists in the periodic adjustment of rations. In all farms, animals graze on a dairy bases, 72 per cent of farmers grow fodder crops for the goats, in rainfed systems (cereals) and under irrigation (sorghum, rye-grass), and the most commonly purchased products are cereals, feeds, sunflower, barley straw and lucerne hay.
