Summary:There was no significant difference between breeds in the digestion of organic matter (OM) and cell wall constituents (CWC). The OM digestibility in the whole tract was 0.59 with 90 percent of the digestion occurring in the stomachs. There was significantly greater non-ammonia nitrogen flow through the abomasum in Herefords (66 g per day) than Brahamans (59 g per day). The ratio of crude protein digested in the intestines to digestible OM was higher in Herefords (0.120) than in Brahmans (0.102), providing a diet capable of meeting the protein requirement of growing cattle. In both breeds, 66 percent of the nitrogen associated with the CWC was digested in the whole tract, essentially all digestion occurring in the stomachs.
