Objective: The purpose of this study is to observe the mice exposed to intake, water intake and body weight change under natural snow and ice environment, changes in the law to clarify the mice intake, water intake and body weight under the snow and freezing weather and thus provide experimental evidence for a reasonable diet in humans snow and freezing weather, water.Methods: 160 healthy 8-week-old Kunming male mice as experimental subjects, adaptive feeding for 7 days, were randomly divided into eight groups: normal group quiet day exposure group, exposure group two days, three days exposure group, four day exposure group, five days exposure group, six days and seven days exposure group exposed groups of 20. All mice were observed daily in general(including coat color and behavior). At room temperature and normal humidity environment, feeding full seven days, 1-7 days of exposure group exposed to 14:00 every day for 1 hour at the outdoor natural snow and ice environment, keeping the rest of the time in normal temperature and humidity environment, mining recorded daily food intake, water intake and body weight changes.Results:(1) Environmental exposure under snow and ice one day, two days, five days, seven-day average intake in mice increased 102.75%, 41.50%, 22.45 %, 10.86% was significantly different(P <0.01); the average intake of snow and ice at the three-day environmental exposure decreased 41.50% statistically significant difference(P <0.01);(2) The study found that exposure of mice under the snow and ice environment first day, second day, third day, fifth day, the sixth day, the seventh day of water consumption is higher than normal temperature and humidity group, indicating in the snow and ice of environmental exposure to the body loss of water. Description of exposure to water demand, the need to pay attention to water During operations and movement under the snow and ice environment, complemented by snow and freezing conditions.(3) Environmental exposure under snow and ice the day the average weight of the mice increased by 18.67% statistically significant difference(P <0.01); environmental exposures under snow and ice the average weight of six mice fell 11.93% had a significant difference(P <0.01).Conclusion:(1) overall trends in mice exposed to the environment under the snow and ice for seven days increased feed intake, indicating that snow and ice under environmental exposure to note supplementary food.(2) overall trends in mice exposed for 7 days under snow and ice environment for water intake is higher than normal temperature and humidity group, indicating in snow exposure to freezing water demand environment, the need to pay attention to add water during operations and movement under the snow and ice environment.(3) often compared to the normal temperature and humidity environment, exposed to snow and ice environment overall trends in mice seven days of weight fluctuations prove at low temperatures under the weight of snow and ice exposed mice environment is unstable, indicating exposure to body weight in snow and ice environment is a signal to pay attention to weight control.
