ABSTRACT
The experiment was conducted from May through September on eighteen males and equal number
of females of Soviet Chinchilla and German Angora rabbits, randomly divided into three groups
(treatments) so that each treatment consisted of 3 males and 3 females of each species. Group I (T1)
was kept in a pen measuring 5.40 x 2.80 m and fitted with a ceiling fan only (48’’). Group II (T2) was
kept in a pen having the same dimensions as T1 but cooled by a fan and a desert cooler. Group III
(T3) was reared in large conventional shed measuring 25.20 x 12.80 m for about 300 animals and
cooled with 12 air fans. The roof height of all the three pens was 2.90 m. T2 provided the most
comfortable environmental conditions in terms of significantly lower dry bulb temperature (28.88±0.13
oC), black globe thermometer temperature (30.57±0.49 oC) and higher relative humidity
(78.65±0.83%). Body weight was significantly (P
