rumen sampling, rumen evacuation
The effect of repeated total ruminal evacuations on feed intake and animal behavior and rate of ruminal recovery expressed as percentage of feed bunk dry matter disappearance were observed in an observation trial with six Angus crossbred steers. Evacuation stimulated meal size and daily intake in comparison to that of a previous feeding. Feed intake decreased with consecutive evacuations. Two evacuation cycles at a 2-day interval may be the practical Limit to frequency of evacuations without a 1 to 2-week recovery period. Rate of recovery of dry matter from the rumen over a 4-hour period was extremely variable and not correlated with feed intake during the same period.
