Climate impacts on reproductive performance of Romanov sheep in the moderate climate

This study aimed to investigate the climatological impacts of air temperature, sunshine duration, and rain precipitation, in a moderate climate, on reproductive performance Romanov sheep continental part Croatia, during two consecutive years (2019-2020). Our included 549 matings with 520 successful conceptions at 5 farms, fertility rate was 94.72%. The percentage lambs delivered winter 53.27% (n = 277), spring 20.19% 105), summer 14.23% 74) 12.31% autumn 64). According percentile ranks classification ratings, thermal conditions have been described as very warm (during 2019-2020), while precipitation conditions, expressed percentiles, were wet 2019) but dry 2020) for this region. peak sexual activity from mid-August until October 2019 end August November 2020 northwestern (NW) Croatia. A Kruskal-Wallis test showed statistically significant difference number pregnant ewes different mating seasons year (p < 0.001). Therefore, we can assume that volume, duration could impact climate.
