ABSTRACT
This study aimed to compare the effectiveness, safety and adverse effects of clove oil with those of salbutamol drug on growth performance, carcass characteristics and some blood parameters for growing rabbits. Forty New Zealand White (NZW) rabbits aged 6 weeks and weighing 950±30 g g were equally and randomly distributed into five groups which containing eight rabbits in each. Rabbits were injected once-weekly for all experimental period up to 14th weeks of age. The first treatment groups were the control without injection (T1), and those in 2nd and 3rd groups were injected with clove oil (25.0 “T2” and 12.5 “T3” µml/ rabbit/week), respectively. whereas, 4th and 5th groups were injected with Salbutamol (50 “T4” and 25 “T5” µml/rabbit/week). The significant (P<0.05) increased in growth performance was observed in rabbits injected with low level of clove oil (T3) compared with other groups. Furthermore, highly significant effect on relative weight of fur and testosterone hormone levels were observed in rabbits injected with low level of clove oil (T3) compared with other treatment groups. In conclusion, clove oil at 12.5 µml., may be useful for improving growth performance, and increases the release of Gonadotropin-releasing hormone.
