    散栏饲养棚式奶牛舍温热环境评价

    Assessment of thermal environment of cow house in free stall bran system

    • 摘要: 选择郑州某奶牛场南北走向的单层彩钢板屋顶的棚式牛舍为试验牛舍,对其相关环境参数测定表明:冬季舍外平均温度和平均THI分别为0.76℃和41.98时,舍内的温度和THI分别为-0.52℃和39.34,卧棚的温度和THI分别为1.63℃和39.99,冬季奶牛直肠温度平均为38.72℃,肩胛前缘温度29.33℃,乳房表面温度35.27℃;夏季舍外温度和THI分别为24.25℃和73.54时,舍内温度和THI分别为25.69℃和74.98,奶牛直肠温度平均为39.42℃,呼吸率平均59.56次/min。因此,在中原地区南北走向的单层彩钢板屋顶棚式牛舍的隔热性能较差,其夏季和冬季的温热环境对奶牛不太适宜。

       

      Abstract: The experimental dairy cow house with the roof of single-layer color steel plate located in Zhengzhou City,Henan Province, which was built along the north to south direction. The air temperature, THI and wind velocity of the cow house were determined and the rectal temperature, the temperature of the frontal shoulder surface, the temperature of udder surface and respiratory rate of the Holstein cows were measured in one dairy farm in the experiment site. The results showed that when the average temperature and THI outside the cow house in winter were 0.76℃ and 41.98, the average temperature and THI were﹣0.52℃ and 39.34 inside the cow house and 1.63℃ and 39.99 in the resting cubicle, the average rectal temperature, the temperature of the frontal shoulder surface and the temperature of udder surface of cows were 38.72, 29.33 and 35.27℃,respectively, in winter. When the average temperature and THI outside the cow house in summer were 24.25℃ and 73.54, the average temperature and THI were 25.69℃ and 74.98 inside the cow house, the rectal temperature and the respiratory rate of cows were 39.42℃ and 59.56times/min in summer. It was reminded that there is an inferior capability of heat insulation of cow house with the roof of single-layer color steel plate and along the north to south direction, and the thermal environment of it in summer and winter was not very suitable for dairy cows in the central plain of China.
