A survey was performed on 48 rabbit closed-cycle farms located in Veneto Region to collect technical information and calculate nitrogen balance. Farms showed great variability in dimensions, management and productivity with on average about 1,200 reproducing does and 54,000 sold rabbits/year. The number of sold rabbits/doe/year was 42.8 on average (from 28.9 to 60.9). Data of reproductive efficiency were significantly correlated with the number of sold rabbits/doe/year, while independent from the number of reproducing does. The N excreted by the doe and its offspring was on average 7.40 kg/year and positively correlated with slaughter weight and number of sold rabbits/doe/year
