Effect of expander processing on fractional rate of maize and barley starch degradation in the rumen of dairy cows estimated using rumen evacuation and in situ techniques



Effect of expander processing on fractional rate of maize and barley starch degradation in the rumen of dairy cows estimated using rumen evacuation and in situ techniques



Animal Feed Science and Technology 104(1/4): 71-94



Effects of heat treatment (expanding) on ruminal and intestinal digestibility of starch in barley and maize grains were studied in an extended 4x4 Latin square experiment. Four lactating Danish Holstein Friesian cows fitted with ruminal, duodenal and ileal cannulae were offered grass-clover silage and grass-clover hay based diets supplemented with soybean meal and either untreated barley, expanded barley (105 degrees C), untreated maize or expanded maize (95 degrees C).
