ABSTRACT
Padina australis was a brown seaweed that had potential as a poultry feed ingredient. The high salt and crude fiber content of the brown seaweed Padina australis is a limiting factor for its use in broiler chicken diets. In this study, immersing in water flow reduced the salt content of the brown seaweed Padina australis. Crude fiber was reduced by fermentation using local microorganisms as inoculum. This study aimed to determine the effect of brown seaweed Padina australis, with reduced salt and crude fiber content, on the growth performance and physiological organs of broiler chickens. This study used a Completely Randomized Design (CRD) with brown seaweed Padina australis levels of 0, 5, 10, and 15% in broiler chicken diets, with each treatment repeated five times. The parameters measured were daily feed intake, daily body weight gain, feed conversion, final body weight , carcass percentage, abdominal fat pad percentage, and physiological organs of broiler chickens. The results showed that the use of Padina australis had no significant effect (p>0.05) on growth performance and significantly reduced the abdominal fat pad percentage of broiler chickens (p<0.05). Furthermore, in this study, Padina australis generally did not affect (p>0.05) the physiological organs, but it significantly affected (p<0.05) the gizzard weight percentage and gallbladder weight percentage of broiler chickens. In conclusion, Padina australis in broiler chicken diets could be used up to 15% without disrupting growth performance while reducing the abdominal fat pad percentage and not affecting the physiological organs of broiler chickens in general.
