The phase from late pregnancy to lactation is known as the transit phase. This period is extremely critical for dairy cows as it brings with it a number of physiological challenges. The transit phase starts three weeks before calving and lasts until three weeks after calving.

During the transit phase, the dairy cow undergoes considerable physiological changes. Her body prepares for the birth and subsequent milk production. During this time, the cow's energy requirements increase significantly. An excessive energy deficit harbours many risks. Diseases such as milk fever, ketosis, postpartum behaviour and abomasal displacement are common during this period and are significantly influenced by the husbandry, feeding and management of the cow during this time. Therefore, appropriate feeding during the transit phase is crucial for the health of the animal and its productivity in the subsequent lactation period. Read here how to get your cows safely through this critical phase.
