Abstract
THREE switchback metabolism studies were conducted to study the effects of replacing corn with 5, 10 and 15% cane molasses. Five percent molasses had no significant effect on any of the parameters studied. At 10 and 15% molasses added at the expense of corn in the basal ration, nitrogen retention and apparent digestibility of dry matter and energy were all significantly improved (P<.05). The total quantity and percent butyric acid in the rumen was significantly increased when the 15% molasses ration was fed. Other parameters were unchanged when either 10 or 15% molasses was added to the basal ration. It is suggested that perhaps cane molasses need not be assigned an energy value lower than corn when fed in limited quantities and in the type of ration used in this study.
