In the first trial steers were fed a basal ration containing approximately 50% roughage. The ration contained 14.3% crude protein and 22.8% crude fiber, dry basis. Apparent digestibility was 65% for dry matter and 66% for crude protein. The feces collected during this trial were dried in a forced air oven at 120 C and ground. The chemical composition of the feces was 13.2% crude protein, 31.4% crude fiber, 2.8% ether extract, 5.4% ash, 38.8% NFE, 70.9% cell walls and 44.8% ADF, dry basis. For trials 2 and 3 a switch-back design was used. In each trial one-half of the steers were fed the basal and the remainder were fed a ration in which dried cattle feces collected during trial 1 were substituted for 20% of the basal ration.57 leavesBTDapplication/pdfIn Copyrightwaste materialLD5655.V855 1974.L83Thesishttp://scholar.lib.vt.edu/theses/available/etd-06122010-020040/
