喷雾通风降温系统对牛舍温湿环境及肉牛血清无机离子的影响
Effect of Spraying Ventilation Cooling System on the Temperature and Humidity of Cow House and on Serum Inorganic Ions of Beef Cattle
摘要
Abstract
In order to study the effects of spraying ventilation cooling system on temperature and humidity of cow house and on serum inorganic ions of beef cattle and to reduce the heat stress,16 Jinjiang yellow cattle were divided into 2 groups.Group Ⅰ was installed spraying ventilation cooling system,and Group Ⅱ ceiling fans.Temperature and humidity as well as the serum inorganic ion concentration before and after the experiment wene measured to study the effect of spraying ventilation cooling system on them.The results showed,compared with the control,the temperature of the experimental group decreased 2.70 ℃ during spraying (P＜0.01),and the relative humidity (RH) increased 13.73％ (P＜0.01).Within each spray cycle (15 min),the temperature of experimental group slowly increased by 0.12 ℃ and relative humidity (RH) decreased by 0.21％ slowly compared with the control group.At the end of the experiment,serum K+ and Na+ content of experimental group significantly increased by 19.13 ％ and 3.33 ％ (P＜0.05) respectively,the Cl-and p2 content didn't have significant difference,while serum Ca2+ content of experimental group decreased by 7.96％ (P＜0.05) than that of the control.In conclusion,spraying ventilation system can improve the temperature and humidity of beef cattle shed,reduce the loss of inorganic ions,and help to maintain the acid-base balance and electrolyte balance of the body and reduce cattle's heat stress in summer.关键词
