Deer experience a period of reduced appetite and growth in winter which has a major impact on venison supply. Photoperiod manipulation has been shown to modify this. The objective of this experiment was to investigate the effect of extended photoperiod and the modifying effect of dietary energy supply in red deer stag calvesForty red deer stag calves born in May/June 1992 were weaned in mid-September and put indoors on a grass silage-based ration. On 30 September the stag calves were weighed and randomised to four treatments groups on the basis of liveweight.
