Physical properties and palatability of cassava peel wafer complete ration for sheep

Cassava peel is waste product from cassava plant which have high carbohydrates that can be used such as source of energy for cattle. Percentage of cassava peel has 0.5-2% from total weight of fresh cassava and inside cassava peel has 8-15%. The usage of forage and agriculture by product increased with feed processing technology as wafer ration complete. The aim of this experiment was evaluate physical characteristic of wafer ration complete for sheep. The parameters observed were water content, water absorption, swelling and density. Analysis data that used were Completely Randomize Design, with four treatments and three replications. The treatments were R1 (70% concentrate + 0% cassava peel + 30% field grass), R2 (70% concentrate + 10% cassava peel + 20% field grass), R3 (70% concentrate + 20% cassava peel + 10% field grass) and R4 (70% concentrate + 30% cassava peel + 0% field grass). The results were subjected to ANOVA and Contrast Orthogonal Test (Steel and Torrie, 1993). The result of this experiment indicated that treatment has significantly influenced to water content, water absorption, swelling and density. The average of water content was 10.060- 13.137%, average of water absorption was 82,490-169,780%, average of swelling was 35.697- 102.295%, average of average density was 0.855-0.870 g/cm3 , and palatability wafer ration complete was 769-866 g/day/head. It concluded that cassava peel is able to be utilized field grass until 30% in wafer ration complete for sheep.
