Genetic components of heat stress in finishing pigs: Parameter estimation
The objective of this study was to describe genetic variability of pig carcass weight as a
function of heat stress. Data included carcass weights of 23,556 crossbred pigs
[Duroc×(Landrace× Large White)] raised on 2 farms in North Carolina and harvested from
May 2005 through December 2006. Weather data were obtained from a weather station
located about 20 km from the furthest farm. Weekly heat load was calculated as degrees of
average temperature-humidity index (THI) in excess of 18° C. The total heat load (H) was the …
