In EstimateBreed: Estimation of Environmental Variables and Genetic Parameters

Environmental Stress Index

Description

Determining the UTI (temperature and humidity index) from the air temperature and relative humidity values over a given period of time

Usage

itu(AAT, RH)

Arguments

AAT	The column with the average air temperature values
RH	The column with the relative humidity values

Value

Returns the stress condition based on the reported air temperature and relative humidity values, being: Non-stressful condition (ITU>=70), Heat stress condition (ITU between 71 and 78), Severe heat stress (ITU between 79 and 83), and Critical heat stress condition (ITU above 84).
