REPROLAC - Extended lactation in dairy production in favor of climate, animal welfare and productivity

The aim of the project REPROLAC is to develop a new strategy for milk production that significantly reduces the environmental and climatic load and at the same time improves productivity and animal welfare as well as the economy of the farmer.

With the new strategy the cow will produce a calf every 18 month instead of the current practice of every year. The feeding of the cow will be organized in a way that will maintain milk production at a high level for up to 500 days as compared with the current 350 days. This is expected to significantly reduce the emission of greenhouse gases and nutrients from dairy farming, because the amount of feed used per kilogram milk produced will be significantly reduced.

It is also expected that the incidence of disease will fall, because problems with disease typically arise around the period of calving. This should result in improved welfare and longevity of the dairy cow.

The project works on the cow’s biological and physiological responses to the new production strategy, as well as the influence of the strategy on environmental and climatic load, productivity, animal welfare, milk quality and the economy of the farmer.

The innovative and holistic approach of the project creates new knowledge and solutions that can be implemented in practice as a significant contribution to the future challenge of increasing food production and at the same time reducing the environmental and climatic load.
