Abstract
The condition under which rabbits are managed, the rearing system, cages type, performance and behavior of does were all investigated. The study of these aspects of management and their relative influences on behavior and production of does revealed that:
1. Compact tired cages reared does spent more time feeding (18.78± 1.05 vs.
11.42± 0.98mm/br) in flat deck cages and higher drinking frequency (0.96± 0.08
vs 0.40± 0.07 freq/hr), but the caecotrophy frequency was lower (0.22± 0.07 vs.
0.33± 0.06 freq/hr)than those reared under compact tired cages. Concerning the
row effect, does kept in higher row spent longer time feeding than those in lower
row but low drinking frequency.
2. Flat deck reared does spend more time in sitting up (34.71±1.36mini’hr) than those reared under compact tired cages (27.73±1.44 mm/br). Also lying (stretching) was longer for those reared under flat deck cages (13.50±1.33 minlhr) than those reared under compact tired cages (12.59±1.42 mm/br).
3. Resting pattern of does revealed that does reared in upper row spent more time sitting (33.28±2.52 mm/br) but lower stretching time (10.23±2.46 mm/br). While, those reared in lower rows spent lower time sitting (24.04±2.52 and 25.68±2.48 mm/br), but higher stretching time (14.06±2.46 and 13.50±2.42 mm/hr respectively). Moreover, walking and running frequency was higher in does reared in compact tired cages (1.02±0.09 and 0.13±0.03 freq/hr).Jn contrary those reared in flat deck cages showed lower walking and running frequency (0.71±0.09 and 0.03±0.02 freq/hr). Similarly, body care behavior was higher in does reared in compact tired cages than those reared on flat deck cages.
4. Higher receptivity and conception rate was observed in does reared on flat deck cages than those reared in compact tired cages. However higher nest score was estimated for those reared in flat deck cages. On the other hand, higher number of litter was observed in flat deck cages and lower pre weaning mortalities than compact tired cages.
Experiment II:
The effect of doe litter separation on the behavior and performance of does was investigated and the obtained results are summarized as follows:
1. The time spent feeding was higher for control group (24.58 ± 4.58) and does separated by metal plate( 1 9.67±2.77mm/br) while the lowest was observed for wire mesh separation (11. 76±2.77 time/br).
2. On the other hand, total time sitting was longer in does completely separated from their young was (42.08±2.72 mm/br). On contrast the control group showed higher stretching time (28.00±4.15 mm/br).
