Extract

In the Basque country and Galicia conditions, forage is usually conserved as silage, which accounts for a great part of cows winter rations. Robust techniques that predict the quality of forages for developing improved feeding strategies and screening of large number of forage samples are needed. In this sense, the gas production technique has proved to be of great interest when considering hays (Khazaal et al., 1995) and grass (Chenost et al., 2001), but information concerning grass silage in vivo data and gas production parameters is scarce. Therefore, the objective of this work is to try to assess in vivo grass silage apparent digestibility by means of gas production parameters.
