Protein degradability was examined by a standard in situ method with three ruminally cannulated sheep. The feedstuffs investigated were: fish meal, meat meal and meat and bone meal. It was found that in situ effective degradability of their crude protein was: 26.96, 43.25 and 44.92 respectively (with an expected ruminal outflow rate of k=0.05). The values obtained are not very dissimilar to those obtained in other investigations. It is concluded that three is great heterogeneity of protein degradability in feeds from animal sources. It is stressed that the main reasons for these differences arise from the diverse technological processes of preparation (especially heat processing) and the quality of the raw material.
