Description
The Mobile Nylon Bag (MNB) technique has been used successfully in protein nutrition studies with swine (Sauer et al., 1983) to determine amino acid availability from protein in specific feedstuffs. Canadian researchers also have tested this technique to predict site of digestion in ruminants (Kirkpatrick and Kennelly, 1987). Differences in small intestinal digestion may explain why animal responses differ to dietary protein sources which have similar ruminal escape values (Owens, 1986). The MNB holds promise to appraise the intestinal availability of undegraded dietary protein though further developmel).t and testing are needed. The objective of this experiment was to examine the effect of diet upon disappearance of dry matter from feedstuffs in mobile dacron bags (MDB) in the rumen and in the intestine of cattle. The diet contained either 50 % or 20 % roughage and feedstuffs tested in MDB included dehydrated alfalfa hay (ALF) and cottonseed meal (CSM) and the two diets being fed.
