The Semex Jersey On Farm Challenge is a competition which attracts a large number of competitors each year. Jersey NZ is very fortunate to have and acknowledges the support of Semex New Zealand as major sponsors of this competition.

Judged on-farm, a different Jersey NZ judge travels in December each year to view teams of animals put forward by members of all regions. At the conclusion of judging, the results are analysed by the Jersey NZ office, regional and overall winners confirmed and the results announced at the Jersey NZ Annual Conference 2023.
