      Abstract
      Fulvic Acid (FA), a class of compounds resulting from decomposition of organic matter, is a part of the humic structure. FA has ability to chelate trace minerals to enable of nutrients uptake. The objective of this study was to evaluate the effect of FA into the diets on body weight, carcass, giblets, and meat cholesterol of broiler chickens. Three hundred and seventy five broilers were allocated into five treatments : R0 (basal diet without FA), R1 (R0 + 0.25% FA), R2 (R0 + 0.50% FA), R3 (R0 + 0.75% FA), and R4 (R0 + 1.00% FA). The treatments were carried out for 5 weeks. Each group consisted of 5 replications with 15 broiler chickens for each replication. Feed and drinking water were served ad libitum. Parameters observed were body weight, percentage of carcass, giblets, digestive tract, abdominal fat, and meat total cholesterol. Data from Completely Randomized Design were analyzed using Analysis of Variance (ANOVA) and any significant different was further tested using Duncan multiple range test. The results showed that there was no significant difference in body weight, percentage of carcass, heart, liver, spleen, bursa fabricius, abdominal fat, proventriculus, gizzard, ileum, secum, length of duodenum, ileum, and secum due to the treatments. Jejunum length was increased by supplementation 0.50% FA (P<0.05). However, supplementation 1.00% FA decreased (P<0.05) percentage of duodenum and colon compared to the control. Supplementation 0.75% FA and 1.00% FA also decreased (P<0.05) percentage of jejunum compared to supplementation 0.25% FA. All the treatments increased meat total cholesterol compared to the control. It can be concluded that supplementation up to 1.00% FA in diets didn’t give negative effects in body weight, carcass, and organ in the chicken. Supplementation 0.50% FA in the diets was potential as organic feed additive that could improve the efficiency of nutrient absorption in the digestive tract, and eliminated the nonspecifically stress of the broiler chickens.
