中文摘要

The purpose of the experiment is to study whether individual and group raising cause problems for dogs. There are 24 dogs, 4 physiology stages: 6 male and 6 female adult, 6 male and 6 female juvenile involved in the experiment. There are five feeding management treatments. Treatment 1. One dog per pen. Treatment 2. Two dogs per pen. Treatment 3. Three dogs per pen. Treatment 4. Six dogs per big pen in daytime (06:30-18:30), one dog per pen in nighttime (18:30-06:30). Treatment 5. Six dogs per big pen for whole 24 hours. The six animals in each physiology stage went through five feeding management treatments. There are six pens for dogs in treatment 1, three pens for dogs in treatment 2, two pens for dogs in treatment 3, and one big pen for dogs in daytime and six pens for dogs in nighttime in treatment 4, a big pen for six dogs in treatment 5. The behavioral observation was done by 6 trained persons. The observer sat in front of pen or pens and recorded behavior every one minute for three days for each physiology stage treatment. The behavioral observation was based on individual dogs, consequence, there were 12 replicates for each treatment. The statistical model is Yijkl =μ+αi+βj+γk+θl+τij+δik+ψjk+eijkl (α=feeding treatment, β=physiology stage, γ=day, θ=replicate). Displacement and low eating activities were considered as an indicator of stressor in the present experiment. The dogs stayed in each feeding management treatment for 3 days. The results showed that the dogs had significantly more drinking (p<0.01), moving (p<0.05), dog sitting (p<0.05), barking (p<0.05), and significantly less lying circle behavior during the first day when compared with the second and third days. One dog per pen had significantly more eating (p<0.001), defecation (p<0.05), urination (p<0.01), and significantly less standing (p<0.01), dog sitting (p<0.01), lying circle (p<0.001). The results also notice that dogs in whole day group housed in a big pen showed significantly less eating time (p<0.01), barking (p<0.001), lying bend (p<0.001), moving (p<0.01), but had significantly more drinking duration (p<0.05), defecation (p<0.01), standing (p<0.05), lying circle compared to dogs housed in treatment 4. The results of present experiment may indicate that dogs spent more time eating and less drinking and defecation time in the half day group housed dogs (treatment 4). This result suggested that we may keep dogs individually in nighttime and keep them group in daytime.
