Supporting cows in early lactation to secure feed intake, stabilise rumen function and sustain performance.
A critical metabolic transition after calving
The weeks following calving are a particularly sensitive phase for dairy cows. Their metabolism must cope with a rapid rise in energy requirements, the gradual restart of milk production and the reactivation of the digestive system. This transition period exposes the animals to nutritional imbalances that can have a lasting impact on their health and performance.
After calving, feed intake capacity increases more slowly than production needs. This gap creates a physiological energy deficit which, if not properly managed, favours the development of metabolic disorders such as ketosis, subacute acidosis or hepatic overload. The transition toward more energy-dense rations must therefore be carefully managed to avoid digestive disturbances and support rumen function. An insufficiently adapted rumen leads to reduced intake, further limiting the cow’s ability to meet her nutritional needs.
Managing the energy gap to prevent metabolic disorders
Diet quality and structure as key performance drivers
The success of this phase relies primarily on the quality and structure of the diet. Palatable forages, well preserved and rich in effective fibre, promote rumination and help stabilise rumen pH. Concentrates must be introduced gradually to avoid excessive fermentations. Mineral and vitamin supplementation also plays a key role by supporting enzymatic functions, strengthening immunity and helping prevent metabolic disorders. Proper liver function—essential for successful lactation onset—depends on balanced micronutrient supply and the availability of glucogenic precursors.
Environmental and management factors supporting intake recovery
The environment strongly influences the success of the transition. Comfortable, dry and well-ventilated housing reduces heat stress and encourages consistent feed intake. Clean and accessible water points, adequate stocking density and smooth access to the feed table all help stabilise feeding behaviour. Daily observation remains essential: any decrease in appetite, change in rumination or fluctuation in body condition should be monitored closely.
The post-calving period is therefore a strategic moment to secure cow health and long-term productivity. A well-managed nutritional transition helps limit metabolic risks, support the rise in milk production and lay the foundations for sustainable performance throughout the lactation.
