Abstract: I. Experiments were conducted with wether sheep in 1964 and 1965 fed pelleted or chopped mature Digitaria decumbens Stent (pangola grass) hay containing different crude protein contents. The voluntary intake of food, digestibility of dry matter and nitrogen, nitrogen retention and apparent time of retention of feed organic matter in the reticulo-rumen were measured. The different crude protein contents of the grass were obtained by applications of urea to the sward 14 and 28 days before cutting for hay in 1964 and 1965 respectively. This treatment increased the crude protein content of the dry matter from 49 yo to 8-7 yo in 1964 and from 3'7 yo to 7.2 % in 1965. The size of the particles of the ground hay before pelleting is given. 2. The mean voluntary intake of chopped fertilized grass was 10 % and 54 % greater than that of the unfertilized; the voluntary intake of pellets made from fertilized grass was 35 yo and 75 % greater than of those made from the unfertilized grass in 1964 and 1965 respectively. 3. The voluntary intake of pellets of unfertilized grass was 7 % and 14 % greater than that of chopped unfertilized grass; the voluntary intake of pellets of fertilized grass was 32 % and 30% greater than that of chopped fertilized grass in 1964 and 1965 respectively. 4. The digestibility of the pellets was less than that of the chopped grass. 5. The apparent digestibility of the feed nitrogen was increased by the fertilizer nitrogen, but grinding and pelleting had no consistent effect. Sheep eating chopped or pelleted fertilized hay were in positive nitrogen balance. 6. The apparent retention time of organic matter in the reticulo-rumen was longer when the sheep were eating chopped hay than when they were eating pellets. In 1964 the apparent retention time of organic matter in the reticulo-rumen was shorter for chopped and pelleted unfertilized grass than for chopped and pelleted fertilized grass, but in 1965 the order was reversed. 7.
