Summary. Seasonality of reproduction in small ruminants is a special biological feature evolved under evolutionary pressure, which has direct effects on production. The authors review the role of light and melatonin in the regulation of this seasonal pattern. They delineate physiological aspects of seasonality, the phenomenon of melatonin receptor 1 (MT1) polymorhism, and current knowledge about MT1 allels as possible markers of reproductive seasonality. Eventually, they summarize achievements of influencing reproductive activity by the use of different forms of photoperiod and melatonin treatment.
