Levels of cassava residue in diets for growing and finishing pigs

Two experiments were conducted in order to evaluate the inclusion of cassav a residue (RIFM) in diets for growing and finishing pigs. In the first expe riment, four levels (0, 6.67, 13.33 and 20%) of RIFM in growing diets were studied. The inclusion of RIFM in the diets caused a cubic effect on averag e daily gain (GPMD, P<0.01, R-2 =0.80, y=804-54.06x+6.03x(2)-0.19x(3)) and final body weight (PMFC, P<0.01, R-2 =0.79, y=60.47-2.87x+0.33x(2)-0.01x(3) ) and a linear effect on average daily intake (CRMD, P<0.04, R-2 = 0.74, y= 2090-136x). The quadratic effect was significant for slaughter body weight (PMA, P<0.05, R-2 =0.69, y=98.88-1.28x+0.05x(2)). In the second experiment, RIFM was studied in four levels (0, 10, 20 and 30%) of inclusion in diets for finishing pigs. Pig performance was not affected (P>0.10) by the inclus ion of any level of RIFM. It was concluded that the inclusion of RIFM in di ets for growing pigs, in levels like 6.67% or higher, decrease swine perfor mance. In the finishing phase, the performance is not affected by the inclu sion of any levels of RIFM, up to 30%.
