冬季出生的犊牛长时间处于低温条件下会出现冷应激体征，严重者甚至出现死亡，直接影响牧场扩群增效。本文从犊牛耐寒度、持续低温对犊牛的危害分析了研发犊牛保暖衣的必要性，从保暖性、舒适性、透气性、色彩融合性、合体性等方面详细介绍了犊牛保暖衣的设计思路，验证了保暖衣的保暖及增重效果，为牧场提高犊牛福利，降低养殖成本，提高效益提供参考。

Calves born in winter will show signs of cold stress under low temperature for a long time，and even die in severe cases，which will directly affect the expansion and efficiency of pasture. This paper analyzed the necessity of developing calf warm clothing from the harm of calf cold resistance and continuous low temperature to calves，introduced the design idea of calf warm clothing in detail from the aspects of warmth retention，comfort, air permeability，color fusion and fit and verified the warmth retention and weight gain effect of warm clothing. It provided a reference for improving the welfare of calves，reducing breeding cost and improving benefits.
