“…In situ degradation is a recently established and representative biological method for assessment of the quality of bulky feeds (Ferri et al, 1998;Huntington and Givens, 1998). In the present study on the rate of disappearance of silage nutrients in the rumen, dry matter and organic matter in corn, which had a lower NDF content, were degraded at a markedly higher rate than those in edible canna.…”

: To assess the potentiality of edible canna (Canna edulis Ker-Gawl.) as economically and environmentally sound animal feed, the feeding value of silage prepared from aboveground parts was examined, in parallel with studies on in situ digestion in the rumen among three local varieties. Contents of crude protein, acid and neutral detergent fi bers and crude ash in canna silage were signifi cantly higher, and that of nonstructural carbohydrate was signifi cantly lower than in corn silage. The pH of corn and 'yellow fl ower' canna silages were signifi cantly lower (3.8~3.9) than either 'green stem' or 'red stem' canna silage (4.4~4.9). The contents of lactic acid, acetic acid, total organic acid and the Flieg's score of 'yellow fl ower' canna silage were equivalent or superior to those of corn silage. The rate of disappearance of dry matter in the rumen was signifi cantly higher for corn silage than for canna silage, while the disappearance of neutral detergent fi ber in canna silage was more rapid during the fi rst 12 hours of incubation, but less rapid thereafter. The effective degradability of dry matter and organic matter of canna silage in the rumen was signifi cantly higher than that of corn. Silage made from edible canna has a potential as a feed for ruminants.

Effect of amount ofPanicum virgatumhay offered on intake, apparent digestibility and short-term intake rate of rams

Switchgrass (Panicum virgatumcv.Alamo) standing hay was cut and offered to 16 rams. The rams were randomly allocated to one of the following levels of feeding: 0·5; 1·0; 1·5 and 2·0✕maintenance. The forage was offered twice a day to the animals; no supplements were given. The animals were individually penned and fitted with faeces collection bags. After 8 days for adaptation, in vivo dry matter apparent digestibility (DMD) and proportion of blades and stem + sheath of the consumed forage were measured for 8 days. DMD varied from 0·310 (0·5) to 0·391 (2·0) and the proportion of the blade fraction in the diet from 0·44 (0·5) to 0·78 (2·0). The short-term intake rate (STIR) of rams was measured for 5 days. The animals were divided randomly into four blocks, with one ram of each treatment in each block. After 4 h without food and 15 min intervals between blocks, the amount of forage consumed during 4 min of active eating was measured. The amounts consumed were (in g DM per min per 50 kg live weight): 0·5: 8·2; 1·0: 7·8; 1·5: 5·3 and 2·0: 5·3 (0·5 = 1·0 > 1·5 = 2·0;P< 0·01). The results show that offer rate of P. virgatum affects the blade: stem + sheath ratio of intake and, therefore, the nutritive value of the diet. Level of feeding before measuring STIR influences the amount of forage consumed during the test.
