Fermented roughages such as sawdust in order to investigate the fattening effect for improving feed value and utilizing ability were examined in growing pigs. The result obtained from the study are summarized as follows: (1) Preliminary experiment was conducted to determine the accurate effect of fermented sawdust fed with level(0, 10, 20, 30 and 40%) in pigs. In daily gain, over all appearance tended to be decreased according to increasing the replace experimental diets at 0, 10, 20, 30% level, and drastically decreased significantly at the 40% level. (2) Daily gain in the fermented diets fed at 10% level groups reduced by 3~8% as compared with that in the control group from 30 to 60kg of body weight, but there was not significantly different(P>0.05). (3) Daily gain in the fermented diets fed at 30% level groups significantly(P<0.05) reduced by about 6~9% as compared with that in the control group of body weight from 60 to 110 kg, but no difference was found among different groups of the fermented diets. Effects of additive limited amino acid(NRC required 30% of) and fish meal oil(10%) on dietary fermented sawdust(30%) were 11 and 19% higher than control diet group, respectively. (4) The concentration of NH₃-gas was drastically decreased about 64~81% and the moisture contents was less than 10% at 30% level of fermented diets as compared to control group.
