The present survey measured the performance and the mortality rates of the biggest game hare farm in Veneto Region (318 hare pairs) during two years (2010-2011). The performances were similar during the two years: the yearly number of alive kits was 10.5 per reproductive present pairs and 11.4 per reproductive fertile pair; the fertile reproductive pairs kindled on average 4.9 times per year, weaned 8.4 kits at 25 d, and produced 7.0 growing hares (60 d of age). Sterility, i.e. the proportion of hare does which never kindled averaged 8.5% of the total number of present does. The culling rate of hare does significantly decreased from 81.1% in 2010 to 69.2% in 2011. The mortality rates of kits varied from 22.9%, during lactation (3-25 d of age) to 9.7% during growth (26-60 d of age). Despite the total mortality of the born hares was not significantly different (38.7% on average), losses were significantly higher in newborn and lactating kits and lower in growing and sub-adult hares during 2010 compared to 2011
