What is PSIV-A-4 Characterization of Heat Stress and Recovery on Productive Performance and Physiological Indicators, Blood and Milk Characteristic, and Gene Expression in Early Lactating Holstein Cows about?
## Abstract We aimed to characterize the novel insights into the recovery (RC) regulation mechanism after heat stress (HS) in early lactating Holstein cows in changing environments using measures of productive performance, physiological and genetic indicators, and blood and milk parameters. Twelve cows (milk yield = 23.64 ± 0.88 kg/d, days in milk = 57 ± 3 d) were randomly and equally housed in environmentally controlled chambers by providing temperature-humidity index (THI) at three levels of 72~73 (25oC, 50~60% humidity, Comfort), 78~79 (28oC, 60~70% humidity, Mild), and 86~87 (31°C, 80~90% humidity, Moderate). The environments inside the chambers were adjusted for 3 days of adaptation at 67~68 THI (22°C, 50~60% humidity, normal) level. After adaptation, cows were received HS for 7 days and RC for 5 days. Data were analyzed using the mixed procedure of SAS. Feed intake and milk yield were lower and water intake was higher in the Moderate than the Comfort and Mild groups (p < 0.05). Concentration of milk beta-casein was lower (p < 0.05) in the Moderate than those of Comfort whereas numerical increase in RC of each group was observed. In Moderate group, blood glucose was lower and
