Genomic selection for heat tolerance in CATTLE

QAAFI Science Seminar on 10 May 2016 Presented by Professor Ben Hayes Research Fellow at the Centre for Animal Science, Queensland Alliance for Agriculture & Food Innovation (QAAFI) We rely on dairy products as a key source of high value protein. However the increasing incidence of heat stress conditions threatens the security of this valuable food, as heat stress leads to reduced production and fertility. The identification of cattle that are genetically more tolerant of heat stress would be an important step in breeding herds better able to cope with the changing climate. This could be accelerated with genomic selection, using genome wide DNA markers that predict tolerance to heat stress. By integrating decade long daily weather station records, daily milk yields, and genotypes from 630,000 genome wide DNA markers in 10,000 cattle, we have derived genomic breeding values for heat tolerance.
