Abstract

Feed represent especial factors of animal husbandry because owning biggest expense from production cost. Feed effi ciency must be done to increase earnings. One of effort for the matter of that is look for alternative of raw material feed of cheaper livestock that is cassava peels. Cassava peels represent waste product from cassava industry with amount 1,998 million ton in the year 2006 in Indonesia (10 percentage of corm of yielded cassava). As constraint is its amount is which have the fl uctuation so that need depository effort of cassava peels. This research aim to know infl uence of use propionic acid as preservative to quality of nutrient of cassava peels. A period of depository observed too for its quality. Research conducted by during six-month in feed industrial laboratory of indicate that addition of 0.3% propionic acids and depository period infl uence quality of nutrient of cassava peels manifestly (P<0.05). Addition of 0.3% propionic acid gratuity not yet able to pursue growth of microorganism during depository. Growth of mould during depository infl uence to descend of water percentage, organics substance, protein, digesting of organic substance and digesting of dry substance.Key words : cassava pells, waste, propionic acids, nutrient.

Abstract

Up to the present time the compost heap of sugar cane has not yet been untilized to the greatest extent. The compost heap, however, has been a major animal feed. In Indonesia about 6.49 million sugar cane tops, 2.78 million ton kletekan and 1.86 million ton sugar sogolan can be obtained each year. By product of sugar processing can yield bagasse, blotong and molasses. All of these by products are potential as a substitute for common forage in ruminants particularly during a relatively long dry season as long protein sources provided. On the other hand the supply of animal feed is becoming scarce and expensive. The farm land growth is limited, especially in dry season. With regard to the potentials mentioned along with animal feed technology, the compost heap of the sugar cane can be converted into essential animal feed. The waste of sugar cane can be processed become wafer and the use can reached 50 – 55 % from the total of the forage in ruminants.Key words : waste, sugar can, forage, wafer, ruminants.
