Description
Mature rumen-cannulated crossbred steers (Bos spp.) maintained on a bermudagrass (Cynodon dactylon (L.) Pers.) hay diet were rumen ally dosed with switchgrass cv. Alamo (Panicum virgatum L.) seed. Seed we1e recovered from faeces (3 steers in Trial 1 and 7 steers in Trial 2) collected at 12, 24, 48, 72, 96 and 120 h post-feeding, Laboratory germination tests conducted on ·recovered seed indicated that germination decreased by 0,7 to 1.0 percentage unit/hour of rCllident time in the gastrointestinal tract. Variation was observed among steers within and among trials for a number of seed traits measured, but there was a consistent pattern among all steers for the linear decline in germination of recovered switchgrass seed.
