ABSTRACT:
The aim of the study was to evaluate the microbiological contamination, odour and dust concentration in poultry farms. In addition, the effectiveness of biopreparation and Yucca schidigera plant extract in manure hygienisation and selected odorous compounds removal was determined. The airborne total dust concentration at poultry production premises averaged 1.44 mg/m3 with a high percentage of the PM10 fraction. High number of bacteria and fungi at 106-1010 CFU / g. was determined in both poultry manure and settled dust. Poultry farm’s air limits of the bacteria and fungi number have not been exceeded. Reported concentrations of PM2.5 and PM10 fractions were 18-20 times higher than acceptable for a 24-hour exposure determined by the World Health Organization. Volatile odorous compounds dominant in poultry farms were: ammonia, acrolein, methyl amine, acetic acid, acetaldehyde and formaldehyde. The concentrations are variable depending on the farm type and stage of the cycle production. The permissible concentration/ exposure limits of ammonia in the air has been exceeded in the laying hens farms I and II, while the concentration of carbon dioxide exceeded the limit value in the third stage of the cycle production on broiler farm III and was close to the limit for laying hens farm I. The maximum cytotoxicity of odorous compounds mixture tested on chick liver hepatocellular carcinoma cell line LMH was 45.7%. It was confirmed by cells morphologic changes after the odorous compounds treatment (ammonia, di-, and trimethylamine). Mineral-microbial biopreparation with Yucca schidigera extract reduced the total number of microorganisms by 1 logarythmic unit in poultry manure and decreased concentration of odorous compounds by 37% - 70% depending on the compound. The use in sequence Y. schidigera extract, and then after 2 days biopreparation can be an effective way to reduce microbiological and odorous hazards on poultry farms.
