Diving into Diets: Phosphorus and Calcium in Lactating Beef Cows

In this episode of Diving into Diets, the discussion examines how different phosphorus and calcium diets affect phosphorus retention, milk composition, calf growth, and bone status in beef cattle. While cows on lower-phosphorus diets maintained milk production and calf growth in the short term, they mobilized phosphorus from bone, unlike cows on high-phosphorus, high-calcium diets. The takeaway is that cows are resilient and can tolerate short-term deficiencies, but inadequate long-term mineral intake may eventually impair performance, underscoring the need for appropriate supplementation.
