Abstract

Abstract The paper presented is dedicated to investigation of the temperature-humidity index (THI) and its impacts on the performance parameters of dairy cattle. These parameters were recorded at four farms in the central Slovakia; the experiments took place three years. These parameters comprised milking time, time spent in the milking box, and connection time. The THI was calculated according to the standard formula and individual periods were established on the basis of achieved THI values. The results showed that the milking time and the time spent in the milking box were not reduced when the THI ranged from 68 to 71, with a daily milk yield of 28.96 kg. If the THI exceeded 72, the milking time and the time spent in the milking box were shortened, which was statistically confirmed. However, even with a daily milk yield of 31.27 kg, a reduction in the milking time and time spent in the milking box was reduced. This was caused by the THI higher than 68, which was also statistically confirmed. Based on the results obtained, the dairy cows respond to heat stress by reducing the milking time and reducing time spent in the milking box.

机器人挤奶对奶牛热应激的影响分析

摘要本文旨在研究奶牛的温湿指数(THI)及其对生产性能参数的影响。在斯洛伐克中部的四个农场记录了这些参数;实验进行了三年。这些参数包括挤奶时间、在挤奶箱中花费的时间和连接时间。THI按标准公式计算，并根据所得THI值确定各个时期。结果表明，在THI值为68 ~ 71的范围内，奶牛的挤奶时间和挤奶箱时间均未减少，日产奶量为28.96 kg。当THI超过72时，挤奶时间和在挤奶箱中花费的时间缩短，这在统计学上得到证实。然而，即使每日产奶量为31.27公斤，挤奶时间和在挤奶箱中花费的时间也减少了。这是由THI大于68引起的，这也是统计学上证实的。根据所获得的结果，奶牛通过减少挤奶时间和减少在挤奶箱中的时间来应对热应激。
