The Effect of Giving Tuna Waste Flour on the Growth of Native Chickens Aged 3-10 Weeks

Livestock in Indonesia is currently experiencing rapid development, with native chicken being a significant source of protein. The protein needs of native chickens vary based on their growth stage. For infants aged 1-1.5 months, the protein content is 18-22%. For infants aged 1.5-3 months, the protein content is 16-18%. For infants 3 months old and above, the protein content is 15-16%. Native chickens require less protein than broiler chickens and laying hens (1). Native chickens require high-quality feed to provide optimal nutrition and achieve the best results. The application of fermentation technology in the feedlot industry also highlights that feed has a significant contribution to production costs, accounting for 60-80% (2). Therefore, efficiency in feed use is the primary key to the sustainability and profitability of the livestock business. Feed ingredients that can be used as alternative feed ingredients include fishery slaughterhouse waste, such as tuna waste. The administration of fish waste meal at a level of 9% had a significant effect on feed consumption and chicken body weight gain. The use of fish waste meal did not hurt livestock (3). The purpose of this study was to determine the effect of providing tuna fish waste flour on the growth variables of native chickens aged 3-10 weeks. The experimental design employed was a Completely Randomized Design (CRD), consisting of five treatments and three replications. The treatments were K0 (ratio without tuna fish waste flour), K1 (ratio containing 3% tuna fish waste flour), K2 (ratio containing 6% tuna fish waste flour), K3 (ratio containing 9% tuna fish waste flour), and K4 (ratio containing 12% tuna fish waste flour).
