Genetic Event Recap: WCGALP

U.S. dairy research was well-represented at WCGALP – the 12^th World Congress on Genetics Applied to Livestock Production (WCGALP) held July 3-8 in Rotterdam, The Netherlands. WCGALP is renowned as the premier international conference covering livestock species.
 
Among the 65 sessions were exciting plenary speakers, recurrent species-orientated sessions, and sessions on specific challenges for animal breeding – like large-scale phenotyping of individual animals, use of whole genome sequence data and improving genomic prediction, and sessions on the contribution that genetics can make to societal challenges, like animal welfare, climate change, biodiversity or control of infectious diseases.
