A large, collaborative research programme, “Pillars of a New Dairy System” was established in 2013 to develop new strategies to improve cow fertility, health, and longevity in New Zealand (NZ) dairy herds.

It is led by DairyNZ scientists and involves a multi-disciplinary team of researchers from AbacusBio, AgResearch, Cognosco, NZ Animal Evaluation Ltd. (NZAEL), Massey University, University of Queensland, Monash University, VetEnt, VetSouth, and Victoria University Wellington.
An introduction to the “Pillars” programme and science highlights to date were presented in Burke et al. (2017). In this paper, we provide an update of the latest findings in key areas driving management and genetic solutions to improve dairy cow fertility and lifetime productivity.
