Breeding and genetics symposium: Breeding for resilience to heat stress effects in dairy ruminants. A comprehensive review

MJ Carabaño, M Ramón, C Díaz… - Journal of Animal …, 2017 - academic.oup.com
Selection for heat tolerant (HT) animals in dairy production has been so far linked to
estimation of declines in production using milk recording and meteorological information on
the day of control using reaction norms. Results from these models show that there is a
reasonable amount of genetic variability in the individual response to high heat loads, which
makes feasible selection of HT animals at low costs. However, the antagonistic relationship
between level of production and response to heat stress (HS) implies that selection for HT …
