Introduction. The relevance of the work is determined by the implementation of
the method of multi-parametric assessment of the microclimate of premises for pigs by
the method of continuous automatic registration. The purpose o f the research was to
conduct a comparative assessment of indoor pollution with carbon dioxide, ammonia,
hydrogen sulfide, methane, and fine dust based on various paratypical factors.
Research methods. Analytical, zootechnical, physical, ethological and biometric
research methods are applied. Research results. A comparative assessment of the
sanitary and hygienic norms for housing pigs in brick premises on concrete and
slotted floors in machines was carried out. It was determined that during the periods
of the year, the average daily CO2 and NH3 air pollution in pig houses with concrete
and slotted floors in the machines were close to the normative values of MPC. The
volume concentration of methane was 1.9-3.4 times higher in the premise with a
slotted floor in the machines, which is associated with the features of the technology
of the self-alloying system of manure removal. According to the calculations of the
correlation between the temperature and the relative humidity of the air outside and
inside the premises, a probable mostly positive connection was determined. The
locomotor activity indices of young pigs were 9.6-12.4 % higher on the slatted floor,
but they were inferior in the food activity index by 6.4-16.2 % to peers kept on the
concrete floor. The variance analysis determined the probable influence fi=0.784) of
the method of housing pigs on solid concrete and slotted floors in machines on the
variability of the volume concentration of methane. It was also found out that the
period of the year likely influenced the variability of air temperature, volume
concentration of carbon dioxide, ammonia and mass concentration of fine dust in the
room fi= 0.799; 0.794; 0.352 and 0.439, respectively). Conclusions. The average
daily volume concentration in the air of carbon dioxide and ammonia in pig houses by
periods of the year approached the normative values of the MPC. The volume
concentration of methane was higher in the premise with a slotted floor, which is
related to the features of the technology of the self-alloying manure removal system.
The probable influence of the method of housing pigs on the variability of indicators
of relative air humidity and volume concentration of methane wasdetermined. The
probable influence of the period of the year on the variability of air temperature
indicators, volume concentration of carbon dioxide, ammonia and mass concentration
of fine dust has also been proven.
