为了解中兽药解暑抗热散对妊娠母猪热应激的缓解效果，选取14头怀孕1月龄的2～3胎次的母猪，按窝体质量及胎次相近的原则随机分成2组，即解暑抗热散组（每800 kg基础日粮中添加解暑抗热散1 kg）和对照组（基础日粮），每组7头，分别测定其热应激相关指标，试验期8 d。结果显示：解暑抗热散组母猪的呼吸频率比对照组降低3.57次/min，体温比对照组降低0.99℃，2组间呼吸频率差异不显著（P＞0.05），但平均体温显著低于对照组（P＜0.05）；母猪产健仔猪数比对照组提高10.52%，发病数比对照组降低5.49%。试验结果表明，解暑抗热散在高温条件下能够显著降低妊娠母猪体温，提高产健仔猪数，降低猪只的发病数，具有良好的抗应激作用。

In order to understand the relief effects of Chinese veterinary medicine summer-expelling and heat-resisting powder on heat stress of pregnancy sow, 14 one-month-old pregnant sows with 2nd-3rd fetal times were selected and randomly divided into control group (basic diet) and summer-expelling and heat-resisting powder group (supplementing 1 kg summer-expelling and heat-resisting powder per 800 kg feed) according to the principle of similar litter weight and fetal times. There were seven sows in each group. The related indices of heat stress were determined. And the test lasted for 8 days. The results showed that the respiratory frequency of sows in summer-expelling and heat-resisting powder group decreased 3.57 times/min than that in control group. And the body temperature in summer-expelling and heat-resisting powder group decreased 0.99 ℃than that in control group. There was no significant difference of respiratory frequency between summer-expelling and heat-resisting powder group and control group(P>0.05). The average body temperature in summer-expelling and heat-resisting powder group is significantly lower than that in control group (P<0.05). The number of healthy piglets per sow in summer-expelling and heat-resisting powder group was increased by 10.52% than control group. The number of diseased piglets in summer-expelling and heat-resisting powder group was decreased by 5.49%than control group. The results showed that summer-expelling and heat-resisting powder under the conditions of high temperatures could reduce the body temperature of pregnant sows, increase the number of healthy piglets and decrease the number of diseased piglets. Therefore summer-expelling and heat-resisting powder had good anti-stress effects.
