A comparison of the digestibility by pigs of whole and rolled sorghum grain fed either in restricted amounts or ad libitum

Abstract

Digestibility comparisons were made between whole and rolled sorghum when pigs were fed either ad libitum or at restricted levels. The method of restriction was to limit each of two daily feeding periods to 15 minutes. The organic matter and N.F.E. digestibility coefficients were higher for rolled grain than for whole grain. Restriction of feeding time had no significant effect on digestibility coefficients of rolled grain. The data indicate a tendency for digestion to be poorest when whole grain is given for restricted feeding periods.
