This study was conducted in order to estimate the effects of the three types of formular concentrate different in its physical form on the rumination of goats. The used feeds were pellet and mash of commercial feed and hardened pellet by adding 10% synthetic bond to mash.
(l) The eating time for hardened pellet was longer than for pellet and shorter than for mash. The boli of pellet became fine particles in the rumen at once.
(2) The time spent before the first rumination was shorter in the case of hardened pellet than in the case of the other two feeds.
(3) The daily duration for rumination was not longer in the case of hardened pellet than the otherwise significantly.
