EFFECTS OF MIXING RATIO OF EXPERIMENTAL DIET WITH BASAL DIET UPON DIGESTIBILITY OF EXPERIMENTAL DIET IN PIGS

Abstract

The effects of mixing ratio of experimental diet with basal diet upon digestibility of the experimental diet in pigs were investigated in the present study using corn, leaf protein concentrate, beet-pulp and corn silage.
The digestibility of experimental diet was influenced by varying the mixing ratio of the experimental diet with the basal diet in all the 4 types of experimental diets. The overall judgements on the results, however, revealed that as the mixing ratio of the experimental diet increased, the standard deviations of the digestibility and nutritive values of the experimental diet became smaller and that the nutritive value of the experimental diet reached an almost stable level when the mixing ratio of the experimental diet exceeded 20%.
