Lush Pasture and Protein Utilisation

22 August 2014



Lush springtime pasture can be a “Catch 22”. The high energy content, abundance and cost effectiveness of home grown pastures are beneficial, however in some cases, the high protein levels can be in excess (in the form of soluble nitrogen in grass) and can lead to nutritional challenges for the herd.

Excess protein is converted to ammonia in the rumen, then into urea by the liver. The urea is then excreted in urine or recycled into the rumen. Sometimes this can lead to ammonia toxicity and reduced protein % in the milk.

Milk protein is made of up Amino Acids (AA), and AA in conjunction with energy derived from glucose make up milk protein. 

Too much protein in the diet can impact on milk protein in two ways.

  • Energy can be diverted away from production and used to get rid of the excess protein in the diet. 
  • AA can also be converted into glucose to provide energy for maintenance rather than milk production.

These two processes will reduce milk production in dairy cows and can impact on cow body condition.

To minimise the risk of excess protein in your cows’ diet, feed a high energy concentrate like CopRice pellets. CopRice high energy pellets assist your cows in capturing the full potential of the readily available protein in lush pastures. It will also help to minimise the risk of loss of body condition in your cows, in turn, improving your farm profitability.
