Abstract
This study was carried out in the Rabbitry of the Poultry Production Unit, Faculty of Agriculture, Mansoura University within the Project ”Productive Improvements of Rabbits”.
The present work investigated the effects of using vegetable market wastes hay (VMWH) in the diets of growing rabbits on their growth performance, digestibility and nutritive value of experimental diets, economical efficiencies, morphologycal and histological characteristics of. tract and some blood components. The VMWH were used instead of clover hay at the level, 0,10,20 and 30 % of the diet.
l. Chemical analysis of VMWH and CH:
- On air-dried basis the VMWH contained 90.2, 70.2, 14.5, 13.89,2.95,38.86 and 20.% dry matter, organic matter, crude protein, crude fiber, ether extract, nitrogen free extract and ash, respectively.
- The corresponding figures of clover hay on air dried basis were 90.0, 76.7,17.0 20.7, 2.7, 36.3 and 13.3 % for the previously mentioned nutrient, respectively.
2- live body weight:
- The substitution of VMWH instead of clover hay had significant (p < 0.05) effects on live body weight through the experimental period from 5 to 21 weeks of age.
- The best results of live body weight at marketing age and at breeding age were recorded for the control group, and less values of live body weight were those of the group of rabbits fed 10% VMWH contained-diet.
Meanwhile those of20 % and 30 % VMWH were intermediate in their live body weight.
3- daily weight gain:
- Daily weight of the control group was significantly (p < 0.05 or p < 0.01) better than those of VMWH contained-diets at the periods 5-9, 9-13,13-17 and 17-21 week. Through the period 5-21 week, the daily weight gain was significantly (p < 0.05) changed with the level of VMWH in the diet.
