Abstract: Freshly harvested cassava roots were chopped manually with a machete into slices of 1 to 6cm thickness and ensiled in 45 gallon (180 litres) barrels the following day with either 2% salt or 50% final molasses by weight. After an ensiling period of 7 days material was removed daily for feeding to pigs. Growing pigs, balanced for sex and litter, were fed in groups of 4 with either (a) a corn/soybean meal ration (b) a ration with 50% corn replaced by saltensiled cassava and soybean meal, or (c) a ration with 50% corn replaced by molasses-ensiled cassava and soybean meal. A vitamin/mineral mix was fed with each ration at the rate of 30 grams per head per day. The animals were adapted for 14 days and the experimental period ran for 23 days when supply of the ensiled cassava was exhausted. The average daily gains (g) of the pigs on the three rations during the 23-day experimental period were 509, 510 and 447, respectively, and were not significantly (P:;;'.05) different. ------ Raices de yuca acabadas de cosechar fueron cortadas manualmente con un machete en trozos de un espesor de 1-5 cm y ensiladas 1'1 dla siguiente en barriles de 45 galones (200 litros) con 2% de sal 0 50% de melaza I(quida, por peso. Despues de un perfodo de ensilaje de 7 dias, se utilize de esta materia diariamente para alimento de cerdos, Cerdos en crecimiento balanceados por sexo y cri3 fueron aIimentados en grupos de cuatro, con una cualquiera de: (a) una racion de maiz/so]a, (b) una racion con 1'1 50% del malz sustituido por un ensilaje salado de yuca y soja (c) y una raci6n con 1'1 50% del maiz sustituido por un ensilaje de yuca con melaza y soja. Una mezcla de vitamina/mineral fue dada diariamente en cada racidn con una proporcidn de 30 pOI cabeza, Los animales estuvieron en un proceso de adaptacidn que duro 14 dfas y 1'1 periodo experimental se extendi6 por 23 d(as, cuando 1'1 suministro de yuca ensilada se agoto. EI aurnentoyromedio de peso diario de los puercos alimentados con las tres raciones durante 1'1 periodo experimental de 23 dias fue de 509, 510 y 447, respectivamente y no hubo una diferencia (P:7 .05) significativa.
