Abstract

Poor environmental management including overexploitation of natural resources, use of pesticides, industrial waste and exhaust from motor vehicle combustion have caused high atomic weight and polyvalent (heavy metal) minerals to dissolve easily and their availability in and above the soil surface and the environment increases. Furthermore, these conditions decrease soil acid-base quality and can contaminate various plant products consumed by humans or animals. These result in a higher prevalence of heavy metal toxicity in plants, livestock, and even humans. Previous studies have been reported to increase the levels of Pb contained in livestock meat. If plants and livestock as human food sources have been contaminated by heavy metals, they will have a very fatal impact on human health. This study was conducted to evaluate the use of Zeolite minerals and organic minerals (Cr-organic) of the rations to reduce the malignancy of heavy metals in vitro using goat’s rumen fluid. This study used a completely randomized design with 5 replications to test 4 types of treatment rations, namely: R1 (unprocessed cocoa pod-based ration), R2 (ammoniated cocoa pod-based ration), R3 (R2 + zeolite 1.5%), and R4 (R3 + organic chromium). The observed variables consist of fermentation characteristics (fermentation pH, production of total VFA and N-NH3) and digestibility of feed nutrients (digestibility of dry matter and organic matter). The results of the first study (in vitro) show that the addition of zeolite minerals and organic minerals in the diet containing heavy metals did not have a significant effect on the fermentation characteristics (pH, total production of VFA and N-NH3) and nutrient digestibility (digestibility of dry matter and organic matter).
