— Comparison between particle size of bolus and ground feeds: influence of in sacco methodology.We have compared particle size distribution of ground feeds (2 hays and 4 concentrates) and masticated bolus by cows.Mastication has no effect on the particle size distribution for concentrates.For forages, the grinding sieve which provides the closest particle size distribution to bolus is 14 mm.L'incubation dans le rumen d'aliment
