What nutrient is crucial for a lactating doe?

In the context of a lactating doe, increased energy (calories) is vital because lactation significantly raises the energy demands on the animal. During this phase, a doe needs to not only maintain her own body condition but also produce milk to nourish her kids. Milk production is an energy-intensive process, so providing sufficient calories ensures that she can meet these requirements without depleting her own body reserves.

While protein, calcium, and fiber are also important for overall health and production, they do not deliver the immediate energy needed in the same way that increased caloric intake does during lactation. Adequate energy supports milk quantity and quality, thereby directly impacting the growth and health of the kids. Hence, while all nutrients play a role in the health of a lactating doe, the priority during this specific physiological stage is ensuring she has enough energy to support her increased metabolic demands.
