Figure 1.
Efficient vs. inefficient cow grazing locations during hot days in August 2016. Efficient cow is shown in green and inefficient cow is shown in pink. Pink dots are at lower elevations with more shade. These two cows are representative of their groups.
Figure 2.
Figure 2.
On a cool day, inefficient cows grazed 1.5 h longer than efficient cows but on a hot day they grazed 2 h less than efficient cows.
