Abstract:

This work was attempted to assess the chemical and nutritive values of cassava foliage and tuber; and used as substitute of concentrate in goat ration. A 75% leaf and 25% tuber mixed cassava was incorporated into T0, T1, T2, T3 and T4 feed at the level of 0%, 25%, 50%, 75% and 100% respectively for in vitro digestibility trial. The rations were in iso-nitrogenous (13.79g/100g CP) and iso-energetic (9.0 MJ Kg-1DM). The cassava tuber contained more DM (42%) than that of leaf (22%) depending on stage of maturity. The leaf contained 14% CP and 20% Crude Fiber (CF) and no significant variation was found between mature and baby leaves while tuber endocarp possessed only 2.45% CP and 10% CF but tuber pericarp contained better CP (4.37%) and CF (23%) respectively. Extreme addition (100%) of mixed cassava maintained 42% organic matter digestibility (OMD) reducing feed cost significantly (p<0.01) by 50% respectively but 50% inclusion of mixed cassava reduced the feed cost (p<0.01) by 25% with highest OMD (>50%). A 50% inclusion of mixed cassava in ration could be more effective approach for small ruminant feeding.
