AB  - Three plant and animal derived protein sources including Fish Meal (FM), Poultry By-products (PBM) and Whole Cottonseed (WCS) were evaluated with <I>in situ</I> technique. The using incubation times were 0, 4, 8, 12, 16, 24 and 48 h. There were significant differences between protein sources in terms of DM and CP disappearances. Effective degradabilities of  Dry Matter (DM) and Crude  Protein (CP) of WCS at 3 outflow rates were significantly higher than those of the other protein sources. Animal-derived protein sources such as PBM and FM had significantly lower effective DM and CP degradability values than those of plant-derived protein sources such as WCS. Therefore, animal-derived protein sources with a low degradability can be used to increase the bypass protein. The  CP degradation parameters obtained in this experiment using sheep would be very useful in improving the accuracy of formulation of sheep diets.
