Kemin studies cow protein utilization

Study suggests importance of balanced amino acids in cow diet

Kemin, in collaboration with Dr. Henri Rulquin from INRA, has produced a study on the efficiency of protein utilization in dairy cows.

The study suggests dairy cow requirements depend on the amino acid profile of their diet. It also suggested that to accurately determine the cow’s needs, dairy formulation should be based on amino acid requirements.

Reduction of ration protein content, with balanced amino acids (digestible methionine less than 33% of digestible lysine), was found to be the best way to reduce feed costs without affecting performance. The efficiency of dietary protein utilization (both crude and metabolizable) was found to increase when essential amino acids were better balanced. As a result, the same performance was shown to be achieved with less protein in the ration.
