The relationship between current weather condition and solar radiation levels with birth data of ewes in the lambing season

In this study, 496 pregnant Karakas sheeps which were grown in 5 different neighboring ranchs in Karagunduz village of Ipekyolu, Van between 1st February and 15th March 2019 were the main materials of the study. 38° 41' 41.2536" North and 43° 38' 46.3128" East coordinates and at an all titude of 1810 m from the date of birth at the start of birth ewe age, type of birth, type of gender and date of birth and birth time data were recorded. Accordingly, the temperature -1.87±0.19 ˚C, the felt temperature -3.64±0.21 ˚C, dew point -4.51±0.08 ˚C, humidity 66.02±0.39 %, wind speed 11.25±0.16 km/h, maximum wind speed 14.06±0.14 km/h, rainfall 0.23±0.04 mm, UV 1.83±0.05, daily global solar radiation 4.34±0.06 kWh/m2 and hourly global solar radiation was measured as 147.14±10.59 kWh/m2. Climatic datalogger was used for solar radiation values. With this device, the intra-folder temperature and humidity was measured as 14.70±0.05 ˚C and 82.93±0.23 %, respectively. As a result of the analysis, the dew point (P <0.000), wind speed (P <0.000), precipitation (P <0.05), daily global solar radiation (P <0.05) and hourly global solar radiation (P <0.05) had statistically significant differences. In addition, the direction of the wind blowing at these dates (southeast 35.7 %, southwest 30.2 %, northwest 17.3 %, northeast 12.9 %, east 3.0 %, south 0.8 %) and weather data (low cloudy 51.0 %, sunny 14.5 %, cloudy % 10.9, light 8.5 %, very sunny 7.9 %, very cloudy 5.8 %, partly cloudy 1.4 %) were evaluated.
