ABSTRACT
ABSTRACT: It has been studied about utilization of expired sausage meal in tilapia (Oreochromis sp.) feed formulations with the aim to assess the level of the specific growth rate, feed conversion ratio and protein efficiency ratio. Five experimental feed contained 25% crude protein in feed which substituted with expired sausage meal as much as A (0%), B (10%), C (20%), D (30%), and E (40%). Test fish used tilapia (Oreochromis sp.) Weight (4.5 ± 1.26 gram) with a maintenance period of 30 days in a controlled aquarium. The results of this research were the best expired sausage meal dose that can deliver growth rate and feed efficiency was best to feed treatment A. This evidenced by the survival value of 90.00 ± 0.00, for specific growth rate of 1.29 ± 0, 09% weight / day, for a feed conversion ratio of 1.94 ± 0.01 and for protein efficiency ratio of 1.96 ± 0.01%.
