title: [Estimation of the quantity of herbage ingested by dairy cows on pasture land. Comparison of methods of estimating digestibility and the mode of fecal sampling].
abstract: Herbage intake of grazing dairy cows was estimated with several techniques. Grab sampling introduced an upward bias in the estimate of faecal output in comparison with field sampling. Estimates of OM digestibility by NIR and faecal index methods were similar except with high level of concentrates.
