Abstract

In a 56-day experiment with 6 local Yellow cattle fed ensiled cassava root-urea, brewers’ grains and rice straw, there were indications (p=0.08) that after an initial 4-week adaptation to the diet, the cattle were growing faster when 1% of biochar (derived from rice husk) was incorporated in the diet.
