Abstract

Feeding trial of six lactating dairy cows, plotted by the crossing-over experimental design, was carried out to investigate effects of whole crop rice silage and its total mixed ration (TMR) with either timothy or alfalfa hay on the lactation performance. The digestion trial, using two dry dairy cattle plotted by a random block experimental design, was also carried out to investigate effects of the two roughages on the utilization and digestion of the TMR and whole crop rice silage in the TMR. The compositional rates of whole crop rice silage and the roughages were adjusted to 20% of the TMR. Digestibility of the rice grain in the timothy-containing TMR was higher than that in the alfalfa-containing TMR because of a higher roughage value index (RVI) and a lower passage rate of the timothy hay in the TMR. Milk production and voluntary dry matter intake, however, were not different between the two TMR. The results suggest some possibility of improving the feeding value of whole crop rice silage by adding roughage of high RVI.
