摘要：
On 21 June 1992 two 13-month-old female Dall Sheep gave birth to single lambs in a 40-acre enclosure at the Yukon Game Farm near Whitehorse. This is the first time that successful breeding has been documented for Dall lambs. This early sexual maturity can be attributed to supplementary feed provided to these sheep. which is also reflected in larger body sizes, improved horn growth and higher productivity.
