Figure S1. Daily average temperature humidity index (THI) across the whole year for the Beijing (BJ) and Ningxia (NX) regions.

Figure S2. The number of records in each temperature humidity index (THI) level for interval from first to last insemination (IFL), conception rate at first insemination (CR_f), and number of inseminations (NS).

Figure S3. Genetic correlations estimated by reaction norm models (RNMs) with ssGBLUP for interval from first to last insemination (IFL), conception rate at first insemination (CR_f), and number of inseminations (NS). The color indicates the magnitude of the genetic correlation. The x-axis and y-axis are the average THI, ranging from 35 to 80.

Figure S4. Trends of phenotypes change along different temperature humidity index (THI) level for interval from first to last insemination (IFL), conception rate at first insemination (CR_f), and number of inseminations (NS).
