To explore the deodorizing effect of microbial deodorant,306 healthy fattening sheep were selected and randomly divided into 3 groups.The microbial deodorant of test group 1 and test group 2 was diluted 30 and 50 times respectively,and the control group was not sprayed with any reagent.The concentration of harmful gas,the number of flies,and the health status of sheep in fattening sheep farms were determined.The results showed that the concentrations of ammonia and hydrogen sulfide at different positions in the fatten-ing sheep house showed the regularity of above the ditch>slate>fence>aisle.Compared with the control group,the concentrations of ammonia and hydrogen sulfide in the ditches,slate frames,fences,and aisles of experimental groups 1 and 2 were significantly lower(P<0.05).Compared with the first group,the concentrations of ammonia and hydrogen sulfide in each position of the second group were significantly decreased(P<0.05).Compared with the control group,the number of flies in the experimental group 1 and the experimen-tal group 2 decreased significantly(P<0.05).Compared with the control group,the incidence and mortality of the experimental group 1 and the experimental group 2 were reduced.It can be seen that the microbial deodorant diluted 30 times can reduce the concentration of ammonia and hydrogen sulfide harmful gases,kill mosquitoes and flies,and reduce the incidence of disease and mortality.
