Abstract. Title of the paper: Influence of artificial and natural light on behaviour during collection of semen and on spermatological parameters in rabbit bucks
39 bucks of New Zealand White hybrids were kept Single over one year under three different light conditions (natural light – NL – with window – floor – relation of 1 : 20 and 27 Lux; artificial light – AL – with 8 or 16 hours light a day and a mean intensity of 60 Lux) and semen was collected once fortnight to analyse parameters of quality. At the same time sexual activity of bucks during collection of semen was assessed. Under NL conditions the highest sexual activity of male rabbits was found. But, decreasing length of day light in autumn led to a decrease in sexual activity. Best results for nearly all investigated semen parameters were detected in bucks kept under AL with 8 hours light a day.
