Abstract excerpt
Climate change has increased the frequency of extreme heat events, extending heat stress beyond tropical and subtropical regions and posing a growing challenge to dairy cattle production and health. Using DHI records from Taiwan, we evaluated genotype by environment interactions (GEI) with reaction norm models (RNM) using temperature-humidity index (THI) as the environmental gradient. The analyzed traits included...
