The Role of Crude Protein in Cattle Health and Nutrition

 

The crude protein content in feed is essential for the development and growth of cattle. The amino acids in protein are essential for tissue growth, healing, enzyme activity genetic function, energy, and critical cellular functions. Cattle obtain protein and all essential amino acids from their feed, so high-quality nutrition is the cornerstone of a successful dairy beef cattle farm.

 

What is crude protein in cattle feed?


It is important to emphasize that not all sources of crude protein have the same digestibility. Crude protein is of true protein and non-protein nitrogenous compounds, and true protein can be degraded or indigestible in the rumen. All types of crude protein have their and play a vital role in animal nutrition.

 

True protein: Made up of amino acids, unlike non-protein nitrogen (NPN), which lacks amino acid components.


Rumen degrad protein (RDP): A true protein that breaks down into peptides, ammonia, and free amino acids in the rumen. Microorganisms use these proteins to grow and microbial protein, which is the main protein source for ruminants.


Rumen undegradable protein (RUP): Also known as bypass protein, RUP is true protein that does not change in the rumen. Some of it is absorbed in the small intestine to meet amino acid requirements, and the rest is excreted.


non-protein nitrogen (NPN): NPN is not a protein, but its nitrogen content helps rumen microorganisms produce microbial protein. For example, urea an important source of NPN microbial protein.
