How to optimize each life stage of dairy ruminants
In ruminant production, every phase of the animal’s life cycle comes with its own biological priorities, risks, and opportunities. Whether it’s preparing a dry cow for the next lactation, supporting calves and heifers through critical development stages, or maximizing milk production during lactation, understanding the needs of each stage is essential for building a healthy, efficient and profitable herd.
At De Heus, we translate scientific knowledge, field experience and farmer insights into clear, stage-specific guidance. Our interactive life stages wheel helps farmers explore what animals need at each moment in their life cycle — including nutritional advice, performance indicators and management recommendations to support predictable production outcomes.
Building strong performance from your cows
The production journey of a dairy cow begins long before she enters the milking station. The dry period — often underestimated — is the foundation of her next lactation. In this stage, metabolic preparation, rumen adaptation and udder conditioning are crucial. The way she transitions through the dry period and calving significantly affects milk yield, fertility, health and longevity.
Calves and heifers represent the future of every dairy herd. During these early life stages, immunity development, optimal growth, and rumen development are key priorities. The quality of their rearing directly influences their performance as adult cows — including their age at first calving, lifetime milk yield and health robustness.
Once cows enter lactation, the goal shifts to supporting high milk production while maintaining strong health. Nutritional demands rise sharply, feed efficiency becomes a major economic driver, and management decisions strongly influence cow comfort, reproduction and long-term productivity.
