Twelve Holstein cows of mid-lactation were selected and paired into three groups, evaporative cooling(EC), high-protein diet (HP) and control (CT), according to calving dates, milk yields and parities during summer season in 1984. The average air temperature, relative humidity and temperature-humidity index (THI) of EC were 27.07℃, 87.47% and 78.74 respectively, and those of CT and HP were 28.21℃,72.25% and 78.96. The air speed of EC was higher than those of CT and HP,but THI was similar. The average rectal...

Twelve Holstein cows of mid-lactation were selected and paired into three groups, evaporative cooling(EC), high-protein diet (HP) and control (CT), according to calving dates, milk yields and parities during summer season in 1984. The average air temperature, relative humidity and temperature-humidity index (THI) of EC were 27.07℃, 87.47% and 78.74 respectively, and those of CT and HP were 28.21℃,72.25% and 78.96. The air speed of EC was higher than those of CT and HP,but THI was similar. The average rectal temperature, respiratory rate and grass intake were not significant difference among these three groups. The rectal temperature and respiratory rate were significantly correlated to the dry-ball temperature and THI, but grass intake was negatively correlated to them. There Was a significant difference in milk yield among three groups. The average milk yields of EC and HP were 16.68 and 8.55% higher than that of CT. Of EC the figure was 7.46% higher than that of HP. Results indicated that evaporative cooling and high protein ration can be used for improving the milk yield during summer season. The latter is better, because it do not need to add any equipment and its feed cost is much cheaper in China. The net income of EC and HP are 0.32 and 0.70 yuan more than that of CT, respectively.

选取泌乳中期黑白花乳牛12头,配对分为三组,蒸发降温为第1组,对照为第2组,高蛋白为第3组。第1组与2、3组除风速不同外,温湿指数(THI)相似。三组牛的直肠温度、呼吸频率和青草采食量没有显著差异,各组牛的直肠温度和呼吸频率与干球温度和THI呈极显著的正相关,青草采食量与其呈极显著的负相关。三组牛的产乳量相差极为显著,第1、3组分别较对照组提高16.68%和8.55%,第1组又较第3组提高7.46%。包括维持在内的产乳饲料利用率,第1、3组分别较对照组高6.6和2.9%。结果表明,蒸发降温和高蛋白均能显著提高夏季乳牛的产乳量,高蛋白不需特殊的设备,饲料成本亦较低,很有推广价值。据经济效益分析,第1组除去电力消耗外,每日每牛净收入可增加0.3209元,第3组增加0.7034元。
