Weaned rabbits Hyla 2000 were housed in a climatized environment at 6,16 and 25°C for 59 days; 64 rabbits per treatment. Rabbits were fed a granulated feed containing (g/kg): dry matter - 885, crude protein - 180, fibre 124, fat - 33.4, ash - 62.4. Eight rabbits per treatment were used for digestibility measurements. Rabbits kept at 6°C were fed also a modified feed mixture containing more fat (69.1g/kg). One half of rabbits kept at 25°C received ascorbic acid in water at 30 mg per kg of body weight, twice a week. As expected, rabbits kept at 16°C gained more than rabbits of other groups. The average daily gain, feed conversion and mortality in this group were 36.0 g, 3.21 kg/ kg and 3.6 per cent, respectively. Rabbits fed the same diet at 6°C gained 30.8 per day and those kept at 25°C gained 27.3 g per day.
