Since the effect of environmental temperature on food utilisation in rabbit is not well known, we studied the relationship between temperature, rabbit daily feed intake and digestibility. Ingesta and excreta were monitored below 11°C, between 12°C and 22°C and between 22°C and 30°C on 6 rabbits (3 males and 3 females, 25 weeks old). Results showed that low temperature increased digestibility of the organic matter nevertheless the contemporary increasing of the daily feed intake. The high temperature did not worse digestibility of organic matter probably in relatioship to the large reduction of the feed intake.
