Abstract . SU)4ARYy was carried out at the Animal Production Department Institut of Animal Physiology and Nutrition (Goett— 984—1990. The study aimed at investigating the possi— of higher digestibility in goats than sheep, which may ferences in anatomical and histological features of the :ract, rate of passage of digesta and ruznen microbial of both species. .ical and histological studies were carried out on 20 kids native goats, Baladi) and 20 lambs (Egyptian native di). In each species 4 animals were slaughtered at each ilowing ages. rth (about 24 h after bflth) aning (2.5 mo of age). 5.5 mo of age three groups each of 4 animals representing tary groups, grazing (C), 60% (C1) and 40% (C2) concent— vups were slaughtered. igestive tract was removed and the physiological volume, and fresh tissue weight were obtained, Also measurements and circumference of different segments of the intestine ded , to calculate the anatomical volume.
