Abstract
A digestion trial was performed with 14 lactating Friesian dairy cows to co mpare the estimated digestibility of crude nutrients after collecting the f aeces for 5, 7 and 9 d. The experimental ration consisted of grass silage ( 7.3 kg DM) and concentrate (10.9 kg DM). Animals were adapted to the ration for 14 d. There was no effect of the duration of the collection period on the estimated mean digestibility of crude nutrients and on the respective s tandard deviation. In consequence, in digestibility trials with cows the co llection period must not exceed 5 d.
