Two feedi;ng trials were carried out in order to study the effect oí different levels of gwund peas (GP) in the diets, on rhe performance and carcass characteristics of growing-finishing pigs. In each experiment 50 pigs, weighing on average 28 Kg, were allocated to sex, weight and litter origin to 5 experimental groups ot 10 pigs each. These experimental groups were randomly assigned to the following treatment: I.- Diet based on barley-fish meal. Contral diet; II.- Diet with 10% GP; III.- Diet with 20% GP; IV.- Diet with 30% GP; V.- Diet with 40% GP. The diets fram the control groups were made up with 15% crude proteinup to 55 Kg and 13% crude protein from 55 Kg to 100 Kg liveweight. With each level of GP, the amount of fish meal in the diet was reduced. In experiment I, cull-graded green peas, containing 25.3% crude protein, were used. In experiment 2 good graded white-yellowish peas containing 18.1% crude protein, were used.The results in both experiments indicate that levels of 10 - 20 - 30 - 40% GP did not affect significantly, daily gains, feed intakes, feed conversion ratio an carcass characteristics. According tó the crude protein content of peas, 30 to 40% GP can totalIy replace fish meal, without detrimental effects. It was conc1uded that dried green cull-graded or white-yellowish peas are very good feed for growing-finishing pigs, that can be included in the diets up to a level of 40% without problerns.
