Understanding protein needs of growing calves

Protein is a key nutrient to achieve target performance. When it comes to growing cattle not all protein sources are created equal. In this video Dr. Mary Drewnoski helps you understand why and how to use this information to make the right choice to meet your calves needs. (The audio is clear after the first minute).

A great example of how not all protein sources is created equal is the response of calves grazing corn residue to distillers supplementation vs. those receiving the same protein and energy from corn plus urea.

When high rates of gain are desired, feeding a source of rumen undegradable protein may be needed. Corn silage based diets can especially benefit.

To make the best use of protein sources that are high in rumen degradable protein make sure you have enough rumen available energy in the diet.
