The objective of this work was to evaluate the effects of supplemental feeding of soy waste on
the feed intake and growth rate of goats. Twenty male crossbred (Boer x local) goats were assigned to two
isonitrogenous diet groups: one of commercial pellet and the other of soy waste. The commercial pellet (1.0%)
and soy waste (0.8%) were provided on the dry matter basis of body weight (BW) per day, to the respective
group of each diet. The soy waste group had lower daily intakes of total dry matter (0.79 vs. 0.88 kg) and
organic matter (665.71 vs. 790.44 g) than the group fed pellet; however, the differences on daily intakes for
grass (0.62 vs. 0.64 kg), crude protein (96.81 vs. 96.83 g), and neutral detergent fibre (483.70 vs. 499.86 g)
were not significant. No differences were observed between groups for BW gain. The feed conversion ratio and
feed cost per kilogram of BW gain were lower for the group fed soy waste than for the one fed pellet. Goats fed
supplemental soy waste have a lower total dry matter intake, feed conversion ratio, and feed cost per kilogram
of body weight gain than those fed commercial pellets.
