Essential Amino Acid, Short Chain Fatty Acid and Omega Content of Skipjack Tuna Offal Meal and its Effects on the Nutrient Digestibility of Local Chicken

In this study, the impact of skipjack tuna offal meal on the nutrient digestibility of local chicken was assessed, with a focus on its short chain fatty acid and omega content. The initial phase involved conducting a skipjack tuna offal meal experiment using a complete randomized design with 3 treatments and 9 replications to examine the short chain fatty acid and omega content. Following this, a second experiment was conducted using 24 male Kampong Unggul Balitnak (KUB) local chickens, employing a completely randomized design with four treatments and six replications. The feed treatments consisted of T0 (basal feed), T1 (basal feed with 10% fresh skipjack tuna offal meal), T2 (basal feed with 10% steamed skipjack tuna offal meal), and T3 (basal feed with 10% fermented skipjack tuna offal meal). Data were collected and analyzed using analysis of variance (ANOVA). The results showed significant differences (p < 0.05) in nutrient digestibility when skipjack tuna offal meal was used as a fish meal replacement. In conclusion, fermented skipjack tuna offal meal was recommended as a source protein for local chickens.
