초록

The effects of castration time on growth and carcass traits of elk bulls were investigated. Twelve bulls at 5 years old were raised and fed on concentrate with ad libitum hay. All animals were allocated randomly to each of four treatment groups (3 heads/group). Groups of each treatment were castrated surgically in March, April or June and managed together with non-castration (entire) treatment. All elk bulls in the trial were slaughtered at same time. Growth parameters, carcass yield and composition were recorded. The total gain and average daily gain was higher when castrated in April (p < 0.05). The entire elk produced heaviest and highest in saddle and brisket portions (p < 0.05). It is apparent that the castrate animals carried more total fat weight and percentages than the entire males (p < 0.05). It was found that loin muscles from non-castrated elk, in comparison with those from castrated one, had higher content of moisture and lower content of fat (p < 0.05). In this study, growth parameters, carcass yields and chemical composition were greatly affected by castration time.
