EFFECTS OF TEXTURIZED SOYBEAN PROTEINS ON INTESTINAL MUCOUS ALTERATIONS OF PRERUMINANT KIDS

This work was carried out to study the effects of the texturised soybe an protein on the mucous characteristics of the duodenum, jejuno and i leum of preruminant kids. Eighteen male kids 3/4 Saanen and 1/4 brazil ian native kid were divided in 3 groups according to the quantity of s oybean added to the cow's milk: COMI (cow's milk), PS30 and PS60 (30 o r 60% of the soybean respectively). The experiment was started with an imals of 3,7kg average weight and 8 days old. The kids were fed twice daily (200g of the experimental diet/BW/day). Feed intake was daily co ntrolled. After sacrifice (49 days) the duodenum, jejunum and ileum se gments were taken from all the animals and submitted to the routine me thodology for histological cuts achievement crowened by Weigert-Van Gi eson, Hematoxylin-Eosin and Van Gieson Tricromo methods. The duodenum and ileum mucous had apparently normal characteristics, while jejuno v illus were long. Independent on the group, duodenum, jejuno and ileum had mucous, submucous, muscular and serous tunic well defined. The sub mucous plexus of neurons had voluminous cellular bodies, excentric nuc leus and little basofilic citoplasm, when compared to similar size neu rons, found in the myenteric plexus. The neurons nucleolus of these tw o plexus were prominent and cromatine grumes in the nucleoplasma were noticed.
