Effect of dietary vitamin E on growth performance of rabbit bucks

摘要

Growth performance, haematology and serum chemistry of rabbit bucks fed vitamin E was evaluated using 40 crossbred rabbit bucks 7-9 weeks of age weighing 650-800 g. The study involved allocating the bucks to four dietary groups at different inclusionlevels of vitamin E/kgfeed (00 mg/kg, 20 mg/kg, 40 mg/kg and 60 mg/kgfor treatments 1,2,3 and 4 respectively) in a completely randomized design (CRD). The bucks were randomly allocated to four treatments often bucks/treatment. Feed and water were provided ad-libitum for sixteen weeks. Other routine management practices were provided as needed. Growth performance, haematology and serum chemistry of the bucks were monitored. Results revealed a significant (P0.05). Bucks in the treatment group performed better than bucks in the control group in all the parameters measured. Hence, including vitamin E to rabbit bucks' diet to as low as 20 mg/kg and as much as 60mg/kg feed can lead to appreciable improvement in growth, haematology and serum biochemical profile of rabbit bucks.
