Bandeira (1995) obtained only 62.92% of apparent OM
digestibility, working with pineapple hay as unique diet
to sheeps, while Barbosa (1997), evaluating the “in vitro”
digestibility of this residue, obtained a percentage of
68.43%.
The high digestibility coefficients found in this trial
to OM may be due to the great proportion of concentrate
in the diet (Table 1), improving the activity of the cellulolitic
bacteria in the rumen, and promoting an increase
in the nutrients digestibility, fact also verified by Bueno
