Which nutrient is crucial for proper milk production in dairy cows?

Proteins are essential for proper milk production in dairy cows because they are the primary building blocks for the milk's components, particularly casein, which is the main protein found in milk. Adequate protein supply is crucial for the synthesis of milk during lactation, as proteins help form not only the milk's proteins but also contribute to overall growth, maintenance, and reproductive functions in cows.

In addition to their role in milk composition, proteins help support the cow's immune system and overall health, allowing for better milk yield and quality. When a cow does not receive enough protein in her diet, it can lead to decreased milk production and lower quality milk. Therefore, ensuring a balanced intake of protein is fundamental for dairy farmers aiming to maximize their herd's milk production.
