The aim of the present investigations was to examine, in two experiments, the influence of three different particle lengths of a grass silage and a maize silage on the physical structure characteristics of total mixed rations in the feeding of high-yielding dairy cows. In order to investigate the effect of particle length on the cascade of digestive processes in the reticulorumen, chewing activity, ruminal volume, particle distribution and particle dynamics, functional specific gravity of the digesta, passage rate and in situ digestibility were determined. Furthermore, the effect of particle length on feed intake and milk yield was investigated.
