| dc.description.abstract | The data from 12 individual cattle grazed on a
uniform sward were used to compare field sampling
of faeces with three time-schedules for rectal
sampling of faeces. Estimates of digestibility from
a faecal nitrogen equation were compared with
estimates based on in vitro digestibility, or modified
acid-detergent fibre determinations, on
clipped herbage samples.
Field sampling gave a lower coefficient of
variation (8%) in chromic oxide content than did
grab sampling (14%). Grab sampling introduced
an upward bias in estimates of faecal output
compared with field samples. The estimate of
digestibility based on the faecal index was intermediate
to those based on clip samples from the
upper and lower horizons of the sward. There was
no difference in the mean digestibilities estimated
from in vitro or MAD fibre. | en |
