Data on the reproductive biology and laboratory management of Philander frenata are presented here. Sensory contact before pairing increased breeding success and reduced aggression between pairs. Gestation period was 13-14 days, with a post-lactation oestrous. Births occurred only between August and February. Mean litter size at birth and at weaning was 5.5 (SD = 2.4) and 4.0 (SD = 1.9), respectively. Sex ratio at birth was statistically biased toward males. The timing of weaning was established at between 70 and 80 days old, with the young weighing from 24 g to 49 g.
本文呈现了南美草原鹿的繁殖生物学和实验室管理数据。配对前的感官接触提高了繁殖成功率，并减少了配对个体之间的攻击性。妊娠期为13 - 14天，哺乳期后有发情期。分娩仅发生在8月至2月之间。出生时和断奶时的平均窝仔数分别为5.5（标准差 = 2.4）和4.0（标准差 = 1.9）。出生时的性别比例在统计学上偏向雄性。断奶时间确定在70至80日龄之间，幼崽体重在24克至49克之间。
