New research from the Swedish University of Agricultural Sciences (SLU) investigated the effect of extended calving intervals on milk production, animal health and fertility. The study concluded that extended calving intervals of 16  months can be an alternative strategy for high-producing herds by better utilising the fertility and high milk yield of modern dairy cows and cutting the labour peaks associated with concentrated calving seasons, contributing to more sustainable production.

The research was for a doctoral thesis by Anna Edvardsson Rasmussen at Department of Animal Nutrition and Care, SLU.
