Pengaruh Penggunaan Tepung Rumput Laut (Gracilaria Verrucosa) Terfermentasi Dalam Ransum Terhadap Produksi Karkas Ayam Broiler (Effect of Fermented Seaweed (Gracilaria Verrucosa) Meal in the Diet on Broiler Carcass Production)

The research was aims to determine the effect of fermented seaweed (Gracilaria verrucosa) meal in the diet on broiler carcass production. The experiment used is 150 broiler chickens (unsex) 1 week old with an average body weight of 163.38 ± 24.67 g (CV 3.04 %). Design used in this research was Completely Randomized Design (CRD), with 5 treatments and 6 replications, so there were 30 cages as experiment units, Each experiment unit consisted of 5 broilers. The treatment includes : T0= Ration without using fermented seaweed meal, T1= Ration using seaweed meal 5%, T2= Ration using fermented seaweed meal 5%, T3= Ration using fermented seaweed meal 7.5%, and T4= Ration using fermented seaweed meal 10%. The data obtained were analyzed using Analysis of Variance (ANOVA) F-test with level 5% and if the result of the analysis showed significant effect of treatment will be followed by Duncan's test. The results showed that treatment using seaweed meal fermented with 5%; 7.5% 10% and 5% using seaweed meal 5% no significant effect on live weight, carcass weight, carcass percentage, non carcass weight, percentage of non-carcass and carcass cut portion. The conclution of the research were fermented seaweed meal can be used in the broiler diet until 10%
