Description
Dairy cows have to have a large feed intake for abundant milk production. It is generally known that a decrease in digestibility of rations is associated with an increased level of feeding (Schneider and Flatt, 1975). When a ration is almost all roughage, it appears that the difference in digestibility between an abundant ration and a scanty one may not be large, but a decrease in ration digestibility with increasing intake is large markedly as the proportion of concentrate in the ration is increased. A ration consisting of whole sorghum plant silage and concentrate develops a tendency to increase the proportion of concentrate in the ration, because the grain contained in the whole plan is practically concentrated (Browning and Lusk, 1967). Therefore this study was done to clarify the effects on digestibility of sorghum silage based diets with increased levels of feeding and of the addition of hay into the diets.
