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 enhance the
uptake of nutrients. This study was designed to investigate whether inclusions
of FA into diets of broiler chickens could improve broiler performances. Three
hundred and seventy five broilers were allocated into five groups : (R0)
control diet (without fulvic acid), (R1) = R0 + 0.25% FA, (R2) = R0 + 0.5% FA,
(R3) = R0 + 0.75% FA, (R4) = R0 + 1% FA. Each treatment consisted of 5
replications and used 15 broilers of each. Feed and water were offered ad
libitum . Parameters observed were feed intake, final body weight, body weight
gain, feed conversion ratio (FCR) and mortality. Data from completely
Randomized Design were analyzed using Analysis of Variance (ANOVA) and any
significant different was further tested using Duncan multiple range test. Feed
intake, final body weight, body weight gain, feed conversion ratio were not
affected by fulvic acid supplementation (P>0.05). Supplementation of fulvic
acid 0.50% decreased mortality rate of broilers composed to the control diet.
