SOIL NUTRIENTS POTENTIALITY OF PIG DEEP LITTER INOCULATED WITH EFFECTIVE MICROORGANISM (EM) IN FERMENTED BED TECHNOLOGY PIG PRODUCTION

Résumé

A total number of thirty six (36) weaner pigs were randomly allotted to two (2) treatments of eighteen (18) weaner each, with each treatment having three (3) replicates of six (6) weaners. The study was designed for the assessment of soil nutrients potentials of pig deep litter inoculated with Effective Microorganism (EM) obtained from pig production using Fermented Bed Technology (FBT). Bedding materials were inoculated with the solution of EM-Bacillus subtilis (STL002), Lactobacillus plantarum (MKL430), Saccharomyces cerevisiae (RSU512) and Actinomycetes (OLT231). Samples were collected from each replicates of bedding without EM (T1, control) and with EM (T2) and individuals sample from each replicate for T1 and T2 were mixed thoroughly in order to obtain homogeneous samples for nutrients analysis. Kjeldhal apparatus, flame photometer, molybdovanadate method and model 55B Atomic Absorption Spectrophotometer (AAS) were used for the analysis. Data obtained from triplicate determination for individuals sample were subjected to t-test analysis and results indicated significant different (p<0.05) between T1 and T2. Pig deep litter macronutrients analysis revealed that Mg=8.42ppm, K=7.25ppm, N=1.62%, P=52.01mg/l, S=9.55% while micronutrients depicted Fe=9.45ppm, Mn=6.60ppm, Zn=5.34ppm, Cu=8.11ppm, Cl=4.81ppm. This
study therefore, showed that Fermented Bed Technology which make use of EM actively breakdown pig waste thus, significantly decreased offensive odour and flies populations. Pig deep litter nutrients content obtained further suggest future use of this biotechnology in a farming system that are economically, environmentally, and socially sustainable.
