A preliminary experiment was carried out to determine the extent to which byproducts of cassava starch processing could be used as the basal diet for growing-fattening ducks. Experimental diets were made from combinations of the two main byproducts: the outer part of the root ("afrecho") removed during the first stage of processing and the residue remaining after removal of the starch ("mancha"). The four basal diets were proportions of 100:0, 50:50, 66.6:33.4 and 75:25 "mancha" and "afrecho" air-dried basis given ad libitum. In addition a fixed quantity (56 g/d) of a protein supplement (36% protein) was also fed. On each treatment there was a group of 10 ducks (White Pekin breed). At 58 days of age the highest liveweight (2128g) and the lowest feed cost were on the diet with equal parts of "afrecho" and "mancha". These results indicate that it is feasible to use cassava starch byproducts as a complete replacement for cereal grains in the fattening of ducks. This abstract relates to the following species: |
