Abstract
The influence of the housing system on sperm productivity and reproductive capacity of rabbits was studied. Indicators like ejaculate volume, sperm density, activity, and concentration, as well as the percentage of fertility were measured for silver breed rabbits of three coloured lines housed in aggregates “Rabbitax-8” and in a modular rabbit house developed by Mykolayiv National Agrarian University. The highest male sperm productivity and reproductive capacity were found for rabbits housed in aggregates “Rabbitax-8”.
