摘要
该研究在22日龄到42日龄期间对随机选取的120只AA商品肉鸡从降低不同幅度饲养温度的角度施加低温冷刺激,试验组比对照组的饲养温度分别降低3、5和7℃,冷刺激时间均为3 h,冷刺激结束后鸡只仍然在正常的饲养温度条件下饲养。该试验通过行为方面来鉴定肉鸡育雏过程中低温冷刺激的效果,并从中找到有益的刺激手段。行为指标主要包括趴卧、采食、站立、饮水、走动和修饰等。结果显示,冷刺激降低温度对走动行为影响显著(P<0.05),对采食、趴卧、修饰、饮水和站立行为无显著影响(P>0.05)。
A total of 120 AA commercial broilers were subjected to low temperature stress with different decreasing degree of temperature from 22 to 42 days of age.The rearing temperature of the experimental groups was 3,5,7 ℃ lower than that of the control group,and the cold stimulation period all lasted 3 hours for both experimental groups and control group.After the cold stimulation,all of the experimental broilers were reared at the normal temperature.The behavior indexes,including lying,feeding,standing,drinking,walking and grooming were used to evaluate the impact of low temperature stress on brooding of AA broiler.The results showed that cold stimulation with decreasing temperature had significant impact on walking（P0.05） of AA broiler but had no significant impact on feeding,lying,grooming,drinking and standing（P0.05）.
