Effect of clinoptilolite addition on bacterial counts in pig slurry

The aim of this study was to determine the effect of natural zeolite (commercial preparation with 80% of clinoptilolite) on counts of different physiological groups of bacteria i.e. sulfide-producing, faecal and total coliform, mesophilic aerobic and anaerobic, and thermophilic bacteria in pig slurry. Zeolite was spread daily directly over partially slatted floor in a dose of 0.4 kg/1 m2 during pig fattening period. The results demonstrated that the counts of all investigated groups of bacteria were lower after addition of zeolite when compared to control slurry.
