红外线灯和浴霸灯采暖对犊牛生长的比较研究

Comparison of the effects of infrared heating and BathBa light heating on calf growth

旨在阐明不同的采暖设备对冬春季节出生犊牛生长发育的影响。选取30头刚出生犊牛(0日龄),随机分为3组,每组10头,分别采用红外线灯采暖、浴霸灯采暖与自然光照进行试验,饲养至60日龄,分别统计0和60日龄犊牛的体重、体尺和腹泻率以及设备耗电等情况。结果:红外线灯采暖组总耗电费少于浴霸灯采暖组;与自然光照组相比,红外灯采暖组与浴霸灯采暖组犊牛的体长、胸围和管围的净增长均差异不显著(P>0.05),但体重和体高显著提高(P<0.05);自然光照组犊牛的腹泻率高于红外线灯采暖组和浴霸灯采暖组,且病死率达16.6%。综上,红外线灯采暖对冬春季节犊牛的生长和健康具有积极的影响,并且加热耗费低于浴霸灯采暖,是冬季犊牛舍供暖方式的较好选择。

In order to ensure that calves born in winter and spring are strong enough to fight against the cold environment,various heating facilities are used for the young animals.However,the effects of different heating facilities on the growth and development of calves are not clear.In this study,three comparative experiments were conducted on the effects of infrared lamp heating,BathBa lamp heating and natural light heating on the growth of calves.We randomly assigned 30 calves to 3 groups with 10 calves in each group.All the calves were fed and managed consistently during the trial.The experiment started from 0 day of age and continued to 60 days of age;and the indexes of weight,body size,equipment power consumption and diarrhea rate of the calves were measured at 0 and 60 days of age,respectively.The results showed that the total electricity consumption of the infrared lamp heating group is less than that of the BathBa lamp heating group.Compared with the natural light heating group,the net growth of body length,chest circumference and tube circumference of the calves in the infrared lamp heating group and the BathBa lamp heating group was not significantly increased,but the body weight and body height of the calves were significantly increased(P<0.05).The diarrhea rate of the calves in the natural light group was higher than that in the infrared lamp heating group and the BathBa lamp heating group,and the fatality rate was as high as 16.6%.Overall,infrared heating had a positive impact on the growth and healthy development of calves in winter and spring,and was more cost effective at the same time.The results of this study served as a reference for farmers in the choice of heating methods for calves in winter and spring.
