Abstract:Antler development is a secondary sexual character for most male cervids. In Père David's deer (Elaphurus davidianus), antlers develop only in the males and the antler morphology is different from other cervids because the tines branch backwards. To understand the occurrence pattern in antler shedding and age-specific variation in antler size, marking antlers before shed, antler collection and measurements were conducted in Beijing Milu Park from December 2008 to March 2009. The results show that the duration of antler casting relates to the age structure of the population. Age-specific antlers weight, burr circumference, beam length, and length of backward branch and width were significantly linearly related to ages, and the relationships for weight and burr circumference to age were most significant. Additionally, the pattern “Each additional year-old, one tine more branched” was not identified completely, and the antler size was not stable when they were more than six years old. Therefore, using antler size to determine exact age is an inaccurate method of age determination.
