Abstract: This experiment was conducted to determine the effects of melatonin on the behavioral time budgets of female mink in growing period based on different analysis models and sampling methods.A total of 12 short-haired black young females (with 6 minks implanted melatonin and 6 minks without implanted melatonin) were randomly selected from the mink farm.Behaviors of each mink in the two groups were video-recorded at 30 d(period Ⅰ), 60 d (period Ⅱ) and 75 d(period Ⅲ) after melatonin implantation.The results showed that there were totally different statistic results for the analysis of fixed effect of melatonin on location, eating, grooming, abnormal behavior and drinking by mixed linear model and generalized linear mixed model, respectively.The results from generalized linear mixed model conformed to the recognized effects of melatonin.Regarding to all behaviors, there were not significant differences for data obtained by instantaneous sampling at no more than 1.5 min interval and continuous sampling (P>0.05).It could be concluded that generalized linear mixed model was more suitable for the analysis of non-normalized data, and instantaneous scan sampling at 1.5 min interval was reasonable to determine behavioral time budgets of mink.

摘要: 本文基于不同分析和取样方法研究褪黑激素对育成期母貂行为分配的影响。从貂场中随机选取当年出生的6只未埋植褪黑激素、6只埋植褪黑激素的美国短毛黑母貂。采用高清摄像头分别在埋植褪黑激素后的第30天(Ⅰ期)、第60天(Ⅱ期)、第75天(Ⅲ期)记录所有水貂的行为。埋植褪黑激素对水貂行为分配的影响,混合线性模型(mixed linear model,MLM)和广义线性混合模型(generalized linear mixed model,GLMM)对于水貂的位置、采食、修饰、异常和饮水行为的分析结果不同,广义线性混合模型的分析结果更符合褪黑激素已知的作用效果;瞬时取样间隔≤1.5 min时,水貂的所有行为比例与连续取样无显著差异(P>0.05)。由此可以推断,广义线性混合模型更适合无法正态化的实验数据的分析;采用瞬时扫描取样法研究水貂行为分配,扫描时间间隔以1.5 min为宜。
