Dairy cattle often experience negative energy balance during the calving transition period, because of reduced feed intake and a drastic increase in nutrient demands after the onset of lactation, thereby contributing to a high risk of metabolic disease and low immunity. This implies that feeding strategies during the calving transition period should be designed to maintain feed intake to mitigate excessive fat mobilisation. An increase in the starch content of post-calving diets is expected to reduce the extent of the negative energy balance and improve performance by increasing energy intake. However, this approach is risky as it may decrease dry matter intake (DMI) and expose dairy cows to sub-acute ruminal acidosis (SARA).
