Sažetak
This research is based on microclimate indicators (temperature, relative humidity, velocity of air flow, ammonia concentration in the object), as well as the presence of bacteria and fungi in two modernly equipped farrowing pens, due to the analysis of the existing hygienic air quality in the intensive production, regarding the number of animals and specific quality of their housing. The farrowing pen A is the size of 770 m² and is divided into two equal parts of the surface of 385 m² with 60 farrowing boxes. The farrowing pen B is the size of 472,5 m² and is divided into four separated spaces, out of which three surfaces are 112,5 m² and the one is 135 m², each equipped with 20 farrowing boxes. The farrowing pen A is equipped with manual and the farrowing pen B with automatic system for microclimate regulation. There were 55 sows in each part of the A object during the first shift, 60 sows during the second and there were 57 sows during the third shift, while parts of the B object were filled up to a maximum with 20 sows per area unit. During each shift of 24 - 25 days at the same intervals, 6 air patternings were taken by the device SAS 100™ (PBI International, Italy), as well as the observation of primary microclimate parameters by Testo and Dräger devices (Germany) in the animals' biozone. The air is patterned on appropriate nutritious surfaces for the isolation of mesophyle bacteria and fungi, and received results are statistically analyzed. According to the results, an average number of bacteria during the research in both objects was on the level of 104 CFU/m³ of the air and fungi up to 10³ CFU/m³ of the air, that gives optimal parameters for this stage of pig breeding production. Such an adequate microbiological air quality is in connection with the determined primary microclimate parameters in optimal limits. The determined differences in the concentration of microorganisms in the air, with smaller number in the B object, could be explained due to the construction of object to lesser area units in which it is possible to achieve better microbiological air quality than in two bigger spatial parts of the A object. On the basis of overall results it can be concluded that under modern conditions of the housing in the farrowing pen, with regard to the standard considering animals' capacity per object, one should expect optimal values of temperature, relative humidity, velocity of air flow and ammonia concentration, as well as microbiological air quality, that will influence the appropriate animals' welfare in the context of microclimate complex. The obtained values of the number of bacteria and fungi in these studies should also be considered as one of the starting points for setting the standard of microbiological air quality in farrowing pens.
