Question

If my ration is right, why do I still have transition problems?

Answer

Transition cow diets are formulated to provide all nutrients required for the cows, reduce the risk of metabolic disorders, and help manage body condition before and after calving. However, a correct ration does not guarantee a successful transition if cows are not consuming it as intended. During this period, feed intake is affected by management, stress, and cow comfort.

Overstocked transition pens increase competition at the feed bunk, which limits access to feed (especially for younger or submissive cows). This often leads to lower intake and more time spent standing, which can increase the risk of transition problems. Feed bunk management also matters. Fewer feed pushups can allow sorting and reduce feed availability. Frequent feed pushups encourage cows to eat more often and reduce the impact of competition in overcrowded pens.

Beyond feeding management, stress could also contribute to transition issues. Cows are often moved multiple times around calving between far-off, close-up, maternity, and lactating cow groups. These frequent changes increase stress and disrupt feeding behaviour. In addition, poor ventilation and heat stress can further impact the cows and increase the risk of issues.

Therefore, transition success depends not only on the ration, but also on management practices.
