Abstract


A total number of 135, unsexed, Rex weaned rabbits, (5 weeks old) were
randomly divided into nine experimental groups (15 rabbits each). The treatment
groups were as follows: the first group received a commercial pelleted diet (Basal
diet) and served as control, the second and third groups were supplemented with 7.5
or 15g Harmala seeds (Peganum harmala L.), (HS) the fourth and fifth groups were
supplemented with 7.5 or 15g Rocket (Eruca sativa) seeds (ES), respectively, the
sixth and seventh groups received (3.75g HS + 3.75g ES, mixture I) or 7.5g HS+7.5g
ES (mixture II)/kg diet, respectively, while the eighth and ninth groups were
supplemented with 75 or 150 mg Zinc (Zn)/kg diet which was added as a Zinc sulfate
(ZnSO4.5H2O), over the recommended zinc needed to meet the nutritional
requirements, respectively. The results showed that rabbits group received diet
supplemented with 7.5 g ES/kg gave the highest final body weight and daily body
weight gain followed by those fed diets supplemented with 150 mg zinc or 15 g
HS/kg diet compared with control diet or the other treated groups. Rabbits received
diet supplemented with 15 g mixture from HS & ES/kg had the lower daily feed
consumption and better feed conversion ratio. There were no significant differences
in digestibility coefficients of crude protein, ether extract, nitrogen free extract and
nutritive values (DCP and TDN) and plasma concentrations of total protein, albumin,
globulin and creatinine among treated groups. Higher CF digestibility, dressing
percentage and hot carcass weight and lower kidneys fat weight percentages were
found by adding HS, ES or zinc into rabbit diets. The ratio of A/G was higher for
rabbits fed diet supplemented with 15 g mixed herbs (7.5g HS+7.5g ES)/kg diet, but
the lower value of A/G ratio was showed for rabbits group received control diet.
Plasma cholesterol and total lipids significantly decreased in all treatments,
especially in 75 mg zinc group compared with control animals.
Evidently, it could be concluded that using harmala, Eruca sativa seeds and zinc
as growth enhancers improved the productive performance, nutrients digestibility,
dressing percentage of growing rabbits and reduced plasma total lipids and cholesterol.
Key words: Rabbits, harmala, Eruca sativa seeds, zinc, performance, digestibility, Carcass, blood analysis.
