Pregnant does select more nutritious diet

Pregnant does select more nutritious diets as compared to open does and does that abort. This is what a recent study showed.

Twelve mixed breed does were grazed during the dry season in northern Mexico. Diet samples were collected from the mouths of the grazing goats. Samples were analyzed for protein, fiber, and minerals.

"We need better food for our babies."
Across months, pregnant does selected diets higher in crude protein than open does and those that aborted. Pregnant does ate forages lower in fiber and 32% higher in calcium compared to non-pregnant does.

Pregnancy did not affect dietary levels of phosphorus, magnesium, sodium, copper, zinc, manganese or iron. Mineral content of the diet was adequte to maintain prgnancy.

Pregnant does did not select forages lower in tannins, alkaloids, saponins, or terpenes than non-pregnant does.
