Abstract
This study was carried out on a number (384) New-Zealand white rabbits to investigate the effect of using of different nest box designs and the role of calcium supplementation on rabbit does maternal behaviour and productivity. Also, the influence was examined on the rabbit kits performance till weaning. In addition to focusing on growing rabbits weaning age and housing in cages vs. pen influences on their behaviour, productive performance and stress level during the growing period till slaughtering.
There was no effect of nest box designs on nest building, nursing, rabbit does productivity in addition to prolactin hormone level. On the other hand, mean of nursing frequency increased in larger size nest box.
There was a clear effect of calcium supplementation on decreasing feeding, milk production and means of litter body weight although, drinking frequency increased. But, There was no effect on means of rabbit does body weight, litter size and prolactin hormone level.
The means of feeding, drinking, locomotory behaviour, mortality rate, body weight and daily weight gain was increased but the resting duration and cortisol hormone level was decreased in weaned growing rabbits at 35 days than that of 21 and 28 day. On the other hand, comfort and social behaviours were not affected.
Six rabbits per pen spent less time in resting, social behaviours, but more times in locomotory behaviour than three rabbits per cage. On the other hand, there was no effect of housing systems on feeding, comfort, aggression, cortisol hormone, body weight and daily weight gain besides, mortality rate and relative growth rate of growing rabbits.
