Sažetak
The study aims was to determine the influence of rainfall precipitation and air temperature on the reproductive efficiency of the Jezerska-Solčava breed in NW Croatia for 7 consecutive years (2013-2019). A total of 2026 sheep were mated, of which 1821 successfully conceived and 2321 lambs were born. The average litter size was 1.23. The average fertility during the study was 92.31%. The distribution of lambs was not equally distributed throughout the year because 75% of all sheep were born during winter and spring (winter 52%; spring 23%; summer 8% and autumn 17%). Sexual activity was the lowest from the end of March to June, while the peak of sexual activity was from the end of July to October. There was a positive or negative correlation (p <0.0001 (Kruskall Wallis)) between air temperature and precipitation and specific reproductive traits (number of pregnant and non-pregnant sheep). We can assume that air temperature and rainfall precipitation during different months or seasons affect the reproductive efficiency of Jezerska- Solčava sheep in northwestern Croatia.
