11/30/2016 Introduction Fulvic acid as supplement influence: • enzymes secretion • hormones structure • absorb heavy metals • absorb toxic pollutants The 16 th Asian-Australasian Association of Animal Production Societies (AAAP) Congress The 16 th Asian-Australasian Association of Animal Production Societies (AAAP) Congress Introduction Supplementation of Humic and Fulvic Acids in Animal Feed: • Humic acids improved broiler performance; and improved perfomance and carcass quality in Pig. • Fulvic acid as supplement improved performance and immune system of broiler chickens, so that can produce good quality chicken, safe and healthy. • Humic acid and fulvic acid in beef cattle incresead growth rate and feed efficiency (Cusack 2008). • Humic and fulvic acid in dairy cattle increased milk fat and decreased mastitis casses.

11/30/2016 Objectives • The purpose of this study was to determine the effect of fulvic acid supplementation in ruminant ration on ruminal fermentation characteristic and protozoa population . The 16 th Asian-Australasian Association of Animal Production Societies (AAAP) Congress The 16 th Asian-Australasian Association of Animal Production Societies (AAAP) Congress MATERIALS & METHODS • This research was conducted using in vitro technique (Tilley and Terry, 1963). • Experiment rations: • Ration A (TDN 69.4% and CP 16.2%) • Ration B (TDN 64.7% and CP 15.6%) • The ration were formulated from nappier grass, rice bran, corn, pollard, coconut meal, soybean meal and CaCO 3 • The ration were suppelemented with fulvic acids. Level of Fulvic Acid: 0, 2.5, 5.0, 7.5 and 10%.

11/30/2016 • Parameter measured: • rumen fluid pH, in vitro dry matter digestibility (IVDMD), in vitro organic matter digestibility (IVOMD), total VFAs and NH 3 concentrations and protozoa population. • In vitro Method: • rumen fluid were collected from local beef cattles. • experiment rations were incubated in rumen fluid and McDougall in anaerobic condition at temperature of 39 o C for 24 h, followed 24 h in pepsin-HCl solution. • total VFA was analysed using steam destilation method, while NH 3 concentration was analyzed using Conway’s microdiffusion method. • rumen protozoa population was counted under microscope after marked by TBFS soultion The 16 th Asian-Australasian Association of Animal Production Societies (AAAP) Congress The 16 th Asian-Australasian Association of Animal Production Societies (AAAP) Congress • Statistical Analysis • The data obtained from the study were analyzed using the analysis of variance (ANOVA) and Duncan’s multiple range test.

11/30/2016 CONCLUSION • Fulvic acid supplementation in both complete rations significantly increase rumen pH but still within the normal level. • However, treatment of fulvic acid supplementation did not affect on fermentation characteristics (digestibility of dry matter and organic matter, total VFA concentration, NH 3 concentration and rumen protozoa population) The 16 th Asian-Australasian Association of Animal Production Societies (AAAP) Congress The 16 th Asian-Australasian Association of Animal Production Societies (AAAP) Congress Thanks Yo u… ..
