Extract

1. In a series of digestibility trials using two Rahmany ewes (see previous publication, el-Shazly, 1958), protein supplements in the form of concentrates, pure proteins or green roughage, supplying 10.16 g. N per day, did not affect significantly the digestibility of cellulose in wheat straw.

2. Decorticated cottonseed cake given at three different levels, i.e. 10.16, 20.32 and 30.48 g. N, did not produce a significant change in wheat-straw cellulose digestibility.

3. The digestibility of dry matter was significantly improved by all supplements used except fish meal and decorticated cottonseed cake at a level of 10.16 g. N per day.

4. Total volatile fatty acids were estimated just before feeding and at different intervals after feeding.

5. The implication of these results for microbial activity are discussed.
