Researching the existence of a number of harmful microorganisms in biological padding for raising pigs used in livestock of Vietnam

Abstract

The research aims to determine the fluctuation of the number of some kinds of harmful microorganisms in pig bed after 5 months using biological preparation. We also compared the inhibition harmful microorganism of biogical preparation producted by Vietnam National University of Agriculture (VNUA) with commercial preparation BALASA.No1. BALASA.No1 preparation was researched and judged in the paper “Evaluating the effect of applying in fermented technology for raising pig in small farm” by Do Quang Dai Master, 2011. So we assessed the effect of VNUA biogical preparation by comparing the microbiological criterias between experimential group (using VNUA preparation) and control group (using BALASA.no1). The results shows that fermenting pig bed by these preparation both intibited the growth of Salmonella and constrained the growth of Coliform and E.coli. Based on this study it could be conclude that using VNUA bio preparation to ferment pig bed can prevent the disease from Salmonella and Coliform.
