Detecting heat stress: Examination of temperature-humidity index thresholds for respiration rate and body temperature in barn- and pasture-housed peripubertal dairy heifers
{{output}}
If animals cannot dissipate accumulated heat from metabolism and the environment, heat stress (HS) occurs. Temperature-humidity index (THI) thresholds for peripubertal dairy heifers are not well defined, despite their known susceptibility to HS. Establishing T... ...
