In recent years, advances in plant breeding were achieved, which potentially led to modified
nutritional values of cereal grains. The present study was conducted in order to obtain a
broad overview of ruminal digestion kinetics of rye, triticale and barley grains, and to
highlight differences between the grain species. In total, 20 genotypes of each grain species
were investigated using in situ and in vitro methods. Samples were ground (2 mm), weighed
into polyester bags, and incubated in situ 1 to 48 h in three ruminally cannulated lactating …
