Abstract

Under the conditions of these experiments, dehydrated comfrey was not a suitable ingredient for a laboratory rat ration at the 20% level, where it supplied half of the protein, and it was completely unsatisfactory at the 40% level. The swine digestion trial indicated that the comfrey used had a dry matter content of 12.1% digestible crude protein, and 52.7% TDN content. The ratings for crude protein, total digestible nutrient content and nitrogenfree extract were all lower for comfrey than for the control ration.
