Summary

The effect of substituting different amounts of heated and unheated beans for barley in diets to cows, on the flow of total nitrogen (N), total amino acid nitrogen (TAA-N) and individual amino acids into the proximal duodenum was studied. Neither heating of the beans nor increasing their proportion in the diet significantly increased the flow of total N at the duodenum; however, increasing the proportion of beans did increase the flow of TAA-N. The substitution of both forms of cracked beans for barley, and at both levels significantly increased the flows of leucine and aspartic acid; flows of histidine, isoleucine, phenylalanine and serine were increased by substitution of both forms of beans but only at the higher level. In the bean supplemented diets significant proportions of all of the ingested amino acids except methionine were apparently destroyed in the forestomachs. The substitution of beans for barley resulted in a net increase of 0·2 g TAA-N flow into the proximal small intestine for each gram of additional dietary N.
