Fig. 2From: Effects of different planes of milk feeding and milk total solids concentration on growth, ruminal fermentation, health, and behavior of late weaned dairy calves during summerTemporal patterns of mean and maximum (max) temperature-humidity index (THI) over the experimental period, with average values of 74.42 ± 2.02 and 83.3 ± 2.51, respectively. The dashed line (THI ≥ 78) represents the threshold for moderate to severe thermal stress [74]Back to article page
