title: Morphological structure of the mucous membrane and submucosa of rumen in calves receiving synthetic or natural beta-carotene and vitamins AD3E.
abstract: In an experiment conducted on 20 calves from 1 day to 12 weeks old, supplements of beta-carotene were fed in the form of Rovimix beta-carotene 10%, artificially dehydrated carrot or vitamins AD3E. Postmortem examination carried out at 12 weeks showed that supplementation of beta-carotene or vitamins AD3E resulted in a better structural development of the ruminal papillae as compared to the control group. In addition, beta-carotene reduced the keratinization of the stratified squamous epithelial cell layer of the rumen and increased the glycosaminoglycan level of that organ wall.
