Item Cassava root flour as a source of energy for growing and finishing pigs(University of Dar es Salaam, 1980) Babyegeya, Wilfred Bitegeko MelwaTwo experiments were conducted to evaluate cassava root flour as a source of energy for growing and finishing pigs by substituting maize with cassava. In the first experiment maize was replaced by cassava up to 45 percent in four- rations (O, ,15 , 30 and 45 percent cassava), and the digestibility of nutrients in all four rations determined and campared. In the second experiment maize was replaced by cassava up to 40 percent in five rations {O, 10, 20, 30 and 40 percent cassava). Growth rate, feed efficiency and carcass character-istics of pigs in all five rations were determined and compared. The digestibility of nutrients in all cassava based rations was significantly greater {P<.05 ) than in the control maize ration. The increase was however at a decreasing rate up to 45 percent cassava indicating that there must be an upper limit of using cassava in the pig rations.The results of the second experiment indicated that it was advantageous to incorporate cassava up to 40 percent in the nations for growing and finishing pigs. Growth rate, feed efficiency and carcass characteristics of pigs on cassava based rations were generally better or equal to that of pigs on maize based rations. The two experiments as a whole therefore, suggest that cassava can to a large degree, be successfully used as sub-stitutes for certain cereals in nutritionally balanced rations for growing and finishing pigs in Tanzania.
