Olive leaves and barley grain degradability were determined in wethers and goats. Olive leaves were incubated in the rumen of animals fed either olive leaves ad libitum or olive leaves supplemented with barley and faba beans. Barley grain was incubated in animals fed alfalfa hay or olive leaves supplemented with barley and faba beans. The effect was mainly due to the increased (P less than 0.001) potentially degradable insoluble fraction. Barley grain protein effective degradability was higher (P less than 0.001) when incubations took place in the rumen of animals fed alfalfa hay (92.9 and 93.1 per cent in goats and sheep) than when animals received supplemented olive leaves (82.6 and 75.1per cent, respectively). Our results state that if rumen degradability is used for protein evaluation of non-conventional feeds, a diet should be determined in animal feed promoting a rumen environment appropriate for the degradation of this type of feedstuffs.
