Abstract

The study objective was to evaluate the difference in calf weight gain and temperature humidity index (THI) in four hutch styles. Holstein calves (n = 120) were housed in four styles of hutches. No significant differences (P ≥ 0.05) existed for calf weight gain between hutches A, B, C, and D (60.32 ± 1.76, 59.93 ± 1.93, 57.09 ± 1.95, and 57.31 ± 1.98 kg, respectively). When outside THI was above 25 oC, the THI varied (P < 0.05) between hutches A, B, C, and D (26.88 oC ± 0.06, 25.99 oC ± 0.09, 26.23 ± 0.06, 25.74 ± 0.07, respectively).
