Abstract

Global warming has caused increasing concern about heat stress. In cattle, heat stress affects both the production and reproduction negatively. Several temperature- humidity indices (THI) are in use to quantify the degree of heat stress. In this study, the authors compared six such indices, together with their thresholds indicating danger of heat stress, for applicability in Hungary. Data from the data base of the cattle farm of Enyingi Agrar Inc. in Kiscserpuszta, Hungary were used in the study. Those cows were selected (n=1007), which had production records on at least 600 days in the study period (1.10. 2001 to 16. 3. 2004). The authors found that two of the six indices worked well on these data in the sense they were able to indicate reduction of milk production due to heat stress. The results show that heat stress affects the production immediately, and even a single heat stress day causes an average milk loss of 1.5 to 2 liters per cow per day (5-10% of the daily production). One to three-day heat stress periods were found to result in about the same milk loss.
