Processes of the Rumen



This lesson would be conducted after instruction has occurred on the digestive tract of a ruminant, prior knowledge of vocabulary is assumed. This lesson is designed to study the physiology of the ruminant stomach and the type of digestion that occurs in each compartment. Students will observe the internal tissue of each of the four compartments of the ruminant stomach and determine the process of consuming dry matter and ending with liquid digestia. Students will dissect the stomach of a lamb taking a piece of each stomach and a sample of digestia from each and record observations using the dissecting microscope.
