In the course of the year, the temperature and relative humidity of the insemination hall of a large pig farm were studied in ten three-week periods. The results were compared with the conception rate of sows inseminated in these periods. The macroclimatic conditions were also studied, and the influence of macroclimate (including temperature and relative humidity) on the microclimate of insemination hall was evaluated. The studied microclimate parameters were found to influence the conception of sows in the first three weeks after insemination. Highly significant differences (significance level of alpha = 0.01) were recorded in the conception of sows after the first insemination, in the occurrence of optimum and increased temperatures, in the occurrence of optimum and increased relative humidity in the summer and winter months. A significant difference at the significance level of alpha = 0.05 was found when the occurrence of increased relative humidity was compared. A high temperature was recorded only in the summer months. In summer and in the first half of autumn (from the 9th of June to the 13th of October) when increased to high temperatures and increased to high relative humidity prevailed in the insemination hall (optimum temperature only in 2.0 to 23.3% of the period; optimum relative humidity in 11.1 to 50.0% of the period), the sow conception rate after the first insemination was low (45.5 to 49.7%). In autumn the microclimatic conditions in the insemination hall returned to the optimum. From the 4th of November to the 16th of February the optimum temperature (optimum in 71.6 to 89.7% of the period) and optimum relative humidity (optimum in 74.2 to 90.7% of the period) prevailed in the insemination hall, enabling an improvement in the conception of sows after the first insemination (71.4 to 80.1%). The temperature inside the insemination hall was influenced by changes in outside temperatures whereas the relative humidity inside the insemination hall was influenced mainly by internal factors.
在一年的时间里，对一家大型养猪场授精厅的温度和相对湿度进行了十个为期三周的研究。将研究结果与这些时期内授精母猪的受胎率进行了比较。同时研究了宏观气候条件，并评估了宏观气候（包括温度和相对湿度）对授精厅小气候的影响。研究发现，所研究的小气候参数会影响授精后前三周母猪的受孕情况。首次授精后母猪的受孕情况、适宜温度和高温的出现情况、夏季和冬季月份适宜相对湿度和高相对湿度的出现情况，均记录到极显著差异（显著性水平α = 0.01）。在比较高相对湿度的出现情况时，发现显著性水平α = 0.05时存在显著差异。仅在夏季月份记录到高温。在夏季和秋季上半叶（从6月9日至10月13日），授精厅内高温和高相对湿度情况普遍（适宜温度仅占该时期的2.0%至23.3%；适宜相对湿度占该时期的11.1%至50.0%），首次授精后母猪的受胎率较低（45.5%至49.7%）。秋季，授精厅的小气候条件恢复到适宜状态。从11月4日至2月16日，授精厅内适宜温度（适宜温度占该时期的71.6%至89.7%）和适宜相对湿度（适宜相对湿度占该时期的74.2%至90.7%）情况普遍，使得首次授精后母猪的受孕情况得到改善（71.4%至80.1%）。授精厅内的温度受外界温度变化的影响，而授精厅内的相对湿度主要受内部因素的影响。
