Abstract

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

气候对中等气候条件下罗曼诺夫羊繁殖性能的影响

本研究旨在研究连续两年(2019-2020年)克罗地亚大陆地区温和气候下气温、日照时数和降雨量对罗曼诺夫羊繁殖性能的影响。本研究包括5个罗曼诺夫羊场549个配种，520个成功受精率，受精率为94.72%。冬季产羔占53.27% (n = 277)，春季产羔占20.19% (n = 105)，夏季产羔占14.23% (n = 74)，秋季产羔占12.31% (n = 64)。根据百分位数排名和分类评级，该地区的热条件被描述为非常温暖(2019-2020年)，而降水条件(以百分位数表示)为湿润(2019年)但干燥(2020年)。克罗地亚西北部的罗曼诺夫羊的性活动高峰期为2019年8月中旬至10月，2020年8月底至11月。Kruskal-Wallis检验显示，一年中不同交配季节怀孕母羊的数量差异有统计学意义(p < 0.001)。因此，我们可以假设，在温和气候条件下，不同季节的气温、降水量和日照时数会影响罗曼诺夫羊的繁殖性能。

Our journal is published quarterly, where the published articles are inserted into areas of animal behaviour, animal biometeorology, animal welfare, and ambience: farm animals (mammals, birds, fish, and bees), wildlife (mammals, birds, fish, reptiles, and amphibians), pets, animals in zoos and invertebrate animals. The publication is exclusively digital and articles are freely available to the international community. Manuscript submission implies that the data are unpublished and have not been submitted for publication in other journals. JABB publishes original articles in the form of Original Articles, Short Communications, and Reviews. Original Articles arising from research work should be well grounded in theory and execution should follow the scientific methodology and justification for its objectives; Short Communications should provide sufficient results for a publication in accordance with the Research Article; Reviews should involve the relevant scientific literature on the subject. JABB publishes articles in English only. All articles should be written strictly adopting all the rules of spelling and grammar.
