Sum of effective temperatures and its effect on yield of Czech Fleckvieh-Simmental
Original language description
This study is aimed on the effect of sum of effective temperature (SET) on the yield of Czech Fleckvieh-Simmental. The study was made on a private farm in Czech Republic (49o12'36.7"N 16o23'42.1"E) between May and July 2016. The cows were stabled in free-stall permanently open-sided barn. There were 114 cows in total present during the whole duration of experiment. Data were collected via data logger placed in the middle of the barn. For this perticular experiment, the section with a largest yield was chosen. The cows in this section were divided into three groups: A (25 and more kg of milk per day), B (20.1-24.9 kg of milk per day) and C (20 and less kg of milk per day). The results shows that there is a significant negative correlation between SET and and yield of all cows (r= -0.535). Also for groups A (r= -0.304), B (r= -0.178) and C (r= -0.355) there is a significant negative correlation. Our results could indicate, that SET is more appropriate for assesing a heat stress than a temperature itself.
