The aim of the article was to compare the annual dynamics of reproductive qualities of Irish origin sows during keeping them in farrowing rooms with different valve and geothermal microclimate systems. It was found that the number of piglets at weaning, which were kept in geothermal microclimate systems, outnumbered peers kept under classical ventilation by 0.37 goals or 2.98% (p <0.05) in winter, by 0.63 goals or 5.08% (p <0.05) in spring, by 0.58 goals or 4.73% (p <0.05) in autumn and by weight of the nest of piglets when weaned by 3.92 kg or 5.85% (p <0.01) in winter months, by 5.90 kg or 8.44% (p <0.001) in spring months, by 4.13 kg or 6.35% (p <0.01) in summer months and by 4.37 kg or 652% (p <0.01) in autumn months. During the autumn, the predominance of pigs kept in the geothermal microclimate system was found over the analogues kept in the valve system in terms of preservation by 4.27% (p <0.05). In terms of absolute, average daily and relative growth of piglets growing in farrowing room with different ventilation had no significant difference during the year. [ABSTRACT FROM AUTHOR] |
