N2 - Gourami (Osphronemus gouramy) are one of the fish species with a high economic value. The increase in gourami consumption has caused a high demand, yet its rearing still faces many problems, especially related to growth. Gourami have a slow growth rate. Lysine is an essential amino acid, which plays a role in the establishment of carnitine, which functions to accelerate growth. Food digestibility is defined as the amount of non-excreted nutrients through stool based on the assumption that the food is ingested by the fish. This research aimed to assess the effect of lysine when in addition to commercial feed and its effect on crude protein and the energy digestibility of gourami (Osphronemus gouramy). The research used an experimental method with a completely randomized design (CRD) with five treatments and four replications. The lysine doses added to the commercial feed were P0 (0%), P1 (1%), P2 (1.5%), P3 (2%) and P4 (2.5%) respectively. The parameters observed in this research were crude protein digestibility and the energy digestibility of the gourami. The data analysis used analysis of variance (ANOVA). The results showed that the average value of the crude protein digestibility in each treatment was 95,515 ± 1,868%; 96.840 ± 1.256%; 97,158 ± 1,426%; 97,825 ± 0,652% and 97,088 ± 1,512% respectively. The average energy digestibility for each treatment was P0, P1, P2, P3 and P4 being 96,480 ± 2,160%; 97,075 ± 1.990%; 97,360 ± 1,898%; 97,848 ± 96,313 ± 0.871% and 2.887% respectively. The results showed that the addition of lysine in commercial feed has no impact and shows there to be no significant difference (p> 0.05) on the crude protein and energy digestibility of gourami.
