STUDIES ON EXPERIMENTAL MODELS USED FOR NUTRITIONAL AND BIOLOGICAL RESEARCH: A TECHNIQUE OF PERMANENT INSTALLATION OF RUMEN CANNULAE IN THE NIGERIAN CATTLE

Abstract

The procedure found suitable for cannulating the rumen of some indigenous breeds of cattle in Nigeria for nutritional analysis and bioassays has been described. The viability of the technique relative to others suggested for exotic ruminants, is reviewed. The anatomical location for a successful implantation in order to reduce complications to the barest minimum has been suggested. The maintenance of the implanted cannula for the purpose of keeping the modified experimental model in perfect health is discussed.
