| description | The factors affecting the quality of cassava roots were studied: var. and age of the plant; DM, starch, and sugar contents in the roots; cyanide contents in leaves and roots. Roots of bitter var. CMC-84 showed higher DM contents than those of sweet var. CMC- 40. Total and reducing sugar contents followed slightly different trends throughout the 9-12 mo. period in both var. Total cyanide content in CMC-84 was less affected by age than that of CMC-40; root parenchyma tissue had moreless stable total cyanide content in both var. Expt. were conducted on the effect of drying cassava on concrete floors and on inclined trays on HCN elimination. Both methods efficiently reduced HCN levels for animal feeding. Sun drying on trays and oven drying were compared. For all var., oven drying at 60 degrees Celsius produced dried chips with a lower HCN content (p less or equal to 0.05). The silage process of CMC-40 reduced total cyanide content to 25-36 percent of the initial concn. after 6 mo. Piglet preference for diets containing 0, 14, 20, 28, and 40 percent CM was studied and a consistent preference was found for diets containing 28 and 40 percent CM. In 1 expt. 53percent of the total feed consumed contained 40 percent CM. In expt. carried out with broilers, results indicated that CM can be used up to 20 percent without causing nutritional problems. Preliminary information was also obtained on cassava processing for the animal feed market on the north coast of Colombia, through a pilot collaborative project carried out by the Integrated Rural Development Program (DRI), the Canadian International Development Agency, and CIAT.

(CIAT) Se estudiaron los factores que afectan la calidad de las raices como: var.; edad de la planta; contenidos de MS, almidon y azucares en la raiz; y contenidos de cianuro en hojas y raices. Las raices de la var. amarga CMC-84 presentaron mayor contenido de MS que la var. dulce CMC-40. Los contenidos de azucares totales y azucares reductores presentaron tendencias ligeramente diferentes durante los 9-12 meses en las 2 var. El contenido de cianuro total se afecto mas con la edad en CMC-40 que en CMC-84, aunque en el tejido parenquimatoso de la raiz se mantuvo mas o menos constante en ambas var. Se realizaron expt. sobre el efecto del secamiento de la yuca en piso de concreto y en bandejas inclinadas en la eliminacion del HCN. Ambos métodos disminuyeron eficientemente los niveles de HCN para el consumo animal. Se comparo el secamiento al sol y el secamiento al horno; en todas las var. el secamiento al horno a 60 grados centigrados produjo trozos secos con un contenido menor de HCN (P menor o igual que 0.05). El proceso de ensilaje de CMC-40 redujo el HCN total a un 25-36 por ciento de su valor inicial en un periodo de 6 meses. Se estudio la preferencia de lechones por dietas con niveles de 0, 14, 20, 28 y 40 por ciento de HIY y se encontraron preferencias consistentes por las dietas con 28 y 40 por ciento. El 53 por ciento del alimento total consumido en uno de los expt. contenia un 40 por ciento de HIY. En expt. con pollos, los resultados indicaron que la HIY se puede utilizar hasta en un 20 por ciento sin que ocasione problemas nutricionales. Ademas, se obtuvo informacion preliminar sobre el procesamiento de yuca para la alimentacion de animales en una region de la Costa Atlantica de Colombia, mediante un plan piloto ejecutado en colaboracion con el Programa de Desarrollo Rural Integrado, la Agencia Canadiense para el Desarrollo Internacional y el CIAT.
