Livestock Weather Safety Index
Adapted from "Notes on Temperature-Humidity Index ", NOAA National Weather Service. EMERGENCY STRESS - Index of 84 or Greater DANGER STRESS - Index of 79 to 83 NO STRESS - Index of 78 or Less DANGER - EXPECT 25% or more increase in transit loss! EMERGENCY - EXPECT 45% or more increase in transit loss! Contact Tom Priddy in the Dept. of Biosystems & Agricultural Engineering, U.K. College of ...
feveR! calculates the values for the Livestock Weather Safety Index (THI) Temperature Heat Index (THI) was developed to estimate the health risk of heat stress. Calculation is based principally on local ambient temperature and relative humidity. feveR documents the environmental data into the animal's health record. THI values are measured and recorded by feveR. The relative level of risk to ...

The Livestock Weather Safety Index (Hahn et al., 2009) is often used, dividing THI into four levels based on respiratory rates (Normal ≤90 bpm, Alert 90 -110 bpm, Danger 110 -130 bpm, and ...
Methods to quantify heat stress in ruminants
The livestock weather safety index [5] is the benchmark commonly used to assign heat stress levels (normal, alert, danger, and emergency) for livestock exposed to hot conditions.
The targeted THI patterns designed to mimic environmental conditions during thermoneutral and heat stress phases were partially based on the Livestock Weather Safety Index using temperature and ...

Livestock Safety Index Chart The Livestock Temperature Humidity Index * (THI Table 1) was introduced by American animal scientists to alert producers of potential heat stress periods for livestock . The THI combines the effects of temperature and humidity into one value.
Fair Veterinarian, Fairboard President, County Youth Coordinator and Fair Secretaries will monitor the heat/humidity situation and will make any necessary decisions. They will keep in close contact with livestock superintendents. If families decide to remove any livestock early because they fear for their animals safety , the 4-H/FFA member will lose ribbon premium and any monetary amount from ...
livestock safety index
livestock safety index (Abbreviated LSI.) An index of animal heat stress. Categories defined from the temperature-humidity index (THI) are based upon an increasing death rate of livestock as the THI value becomes larger. LSI has been related to other heat-related responses of mammals such as weight gain, milk production, and blood chemistry.
The Livestock Risk Index The Livestock Risk Index (also known as the Comprehensive Climate Index ), uses temperature, relative humidity, wind speed and solar radiation to produce an adjusted temperature value that represents risk to livestock 1.
