在跨界实验设计中使用了八只nubian和八只高山乳制山羊，以确定30分钟的孤立对甲状腺素（T4），三碘甲胺（T3），皮质醇，去甲醇，去甲肾上腺素（Norpinephrine（Nor）和肾上腺素（NOR）和肾上腺素（NORPINE）的行为和血浆浓度的影响（ EPI）。 假设隔离会产生类似于恐惧的情绪状态。 在最初的隔离五分钟内记录了局灶性动物行为。 通过在0（隔离期间），40、50和60分钟（返回其组后），通过颈式插管（返回其组），通过颈套管获得血液样本。 对分离的反应在生理上是通过NOR（p <0.01）而不是T3，T4，皮质醇或EPI的等离子体浓度升高的，表明表明同情分泌的。 孤立的山羊也更频繁地发声（p <0.01），并花费大量时间嗅探，小跑和饲养（p <0.05）。 努比亚人的反应确实比隔离更强烈（升高，小跑和饲养，p <0.01）。
Eight Nubian and eight Alpine dairy goat does were used in a crossover experimental design to determine the effect of 30 min of isolation on behavior and plasma concentrations of thyroxine (T4), triiodothyronine (T3), cortisol, norepinephrine (NOR), and epinephrine (EPI). Isolation was hypothesized to produce an emotional state analogous to fear. Focal animal behavior was recorded for the initial five min of isolation. Blood samples were obtained via jugular cannulae at 0 (immediately prior), 10, 20, 30 (during isolation), 40, 50 and 60 min (after return to their group). Response to isolation was characterized physiologically by increased plasma concentrations of NOR (p < 0.01), but not T3, T4, cortisol or EPI, indicating a sympathetic discharge. Isolated goats also vocalized more frequently (p < 0.01) and spent a greater amount of time sniffing, trotting and rearing (p < 0.05). The Nubian does reacted more strongly (elevated NOR, trotting and rearing, p < 0.01) to isolation than the Apline does.
