Shrimp Waste Fermentation by Isoptericola sp. Strain A10-1 as a Feed Ingredient for Improving Yield Carcass and Performance of Magelang Duck

Shrimp waste can be utilized as feed in an effort to reduce environmental pollution and greenhouse effect. Magelang ducks are one of the sources of Indonesian germplasm. The purpose of this research was the use of fermented shrimp waste by Isoptericola sp. bacterial chitin biodegradation as duck feed compound to improve the performance and carcass quality. The research consisted of seven treatment feeds, namely, R0 = concentrate feed as a control, R1 = shrimp waste non-fermented (SWNF) 5%, R2 = (SWNF) 10%, R3 = (SWNF) 15%, R4 = shrimp waste fermentation (SWF) 5%, R5 = (SWF) 10%, and R6 = (SWF) 15%. Each treatment was repeated five times in four enclosure flocks (seven treatment feeds × five replicates × four blocks) for 140 ducks. Feed and water was given ad libitum. The inoculum with Isoptericola sp. (3 × 106 cfu/kg) has a fermentation time (7 days) at room temperature 28 °C to 33 °C. The addition of shrimp waste fermentation levels 5%, 10%, and 15% did not differ significantly on the performance of Magelang ducks, i.e., live body weight, carcass percentage, body weight gain, and feed conversion, and also did not degrade the performance of Magelang ducks.
