Seasonal calving for optimal grass use

This case study from the Netherlands examines Auke Spijkerman’s seasonal calving system on a temperate maritime farm with sandy loam soil, designed to enhance sustainable grazing. The system uses rotational grazing to improve soil health and reduce environmental impact. Funded by the European Union, a cost-benefit analysis shows initial investment of €120,000 and annual costs of €35,000, with projected annual benefits of €58,000 from increased milk yield, improved pasture productivity, and reduced fertiliser use. Net annual benefit is €23,000, with a payback period of 5.2 years. Benefits include improved animal welfare, lower greenhouse gas emissions, and increased farm resilience, demonstrating a viable model for sustainable dairy farming in temperate regions.
