Variation between individual cows in in situ rumen degradation characteristics of maize and grass silages

This is the authors' abstract. We don't add key points for this paper.

Highlights⿢ Between-cow variation is essential to obtain accurate estimate of rumen degradation.⿢ Pooling of rumen incubated residues depends on variation between individual cows.⿢ Three cows are sufficient for in situ rumen incubations of grass silages.⿢ Four or more cows are required for in situ rumen incubations of maize silages.
