Abstract

The aim of this study was to investigate the development of the pupillary light reflex and menace response in neonatal lambs and goat kids. Thirty lambs and 33 kids were assessed daily from birth until the pupillary light reflex and menace response had become established. All animals had a controlled pupillary light reflex within 20 h of birth. Lambs and kids had developed menace responses by 8 ± 3 and 14 ± 2 days, respectively. The Mann-Whitney test revealed a significant difference (P < 0.001) in the ages at which lambs and kids developed a menace response. Male kids developed this response significantly (P = 0.006) later than females. There was no sex difference in the menace response in the lambs. Overall, the findings indicated that lambs develop a menace response earlier than kids, and female kids develop this response more rapidly than their male counterparts.

摘要

本研究旨在探讨新生羔羊和山羊幼崽瞳孔对光反射和惊跳反应的发育情况。30 只羔羊和 33 只山羊幼崽从出生起每天进行评估，直到瞳孔对光反射和惊跳反应建立。所有动物在出生后 20 小时内均有控制良好的瞳孔对光反射。羔羊和山羊幼崽分别在 8 ± 3 天和 14 ± 2 天形成惊跳反应。Mann-Whitney 检验显示，羔羊和山羊幼崽形成惊跳反应的年龄存在显著差异（P < 0.001）。雄性山羊幼崽的惊跳反应形成时间明显晚于雌性（P = 0.006）。在羔羊中，惊跳反应不存在性别差异。总体而言，研究结果表明，羔羊比山羊幼崽更早形成惊跳反应，而雌性山羊幼崽比雄性幼崽更快形成惊跳反应。
