Effects of dietary seaweed and carrageenan waste on performance and carcass quality of broiler

Gracilaria sp. and Eucheuma cottonii are seaweeds that contain vitamins (vitamin A/β-carotene, B1, B2, B6, B12, and vitamin C) and minerals (potassium, calcium, phosphorus, sodium, iron, and iodine). Carrageenan waste still has nutrients that can be used as animal feed. This study investigated the effects of Gracilaria sp., E. cottonii seaweed, and carrageenan waste in diets on broiler chickens’ growth and carcass components. 112 DOC broilers for 6 weeks in experimental cages at the Agribusiness Development Laboratory for Animal Husbandry and Fisheries, Tadulako University, in South Sibalaya Village, Tanambulava District, Sigi Regency, Central Sulawesi Province. This study used a completely randomized design (CRD) with 7 treatments and 4 replications. They were assigned to the control diet with 2.5% Gracilaria sp., 5% Gracilaria sp., 2.5% E. cottonii, 5% E. cottonii, 2.5% carrageenan waste, and 5% carrageenan waste. Broiler chicken’s parameters were feed intake, body weight gain, feed conversion ratio, and carcass components. Based on the results of this study, the best diet use was found in the use of 2.5% Gracilaria sp., 2.5% carrageenan waste, and 5% E. cottonii.
