Conteúdo: | Studies have been conducted in vitro and in vivo to determine the nature of the inhibition by starch of cellulose digestion by rumen microorganisms. The in vitro studies indicated that the inhibition was due primarily to a competition between the cellulolytic and amylolytic groups of bacteria for nutrients. The major nutrient was nitrogen, although the results suggested other nutrients could also be involved. In vivo trials with filter paper in nylon bags in the rumen of sheep showed similar inhibition of cellulose digestion when the sheep were fed increasing proportions of corn in hay and corn ratios. With to corn ratios of 2:1 or 1:1, partial or complete alleviation of tghe inhibition of cellulose digestion could be obtained by supplementing the rations with urea; however, when the ratio was 1:2 additional nitrogen as urea was ineffective. Although other nitrogen supplements were active, urea appeared to be most efficient in alleviating the inhibition.
