Calf nutrition plays an essential role in determining the overall growth and health of a calf. One such crucial aspect of calf nutrition is understanding the correct amount of milk replacer a calf requires, which is where the Calf Milk Replacer Calculator comes into play.


Calf Milk Replacer (CMR) is a commercially manufactured product designed to mimic a cow's natural milk. It's a well-balanced diet for calves providing the necessary nutrients and energy required for optimal growth and development.

Breaking Down the Formula

The calculator operates on the formula: Amount of CMR = Calf Weight x Daily Milk Replacer Feeding Rate. The feeding rate varies with age: for newborns to 3 weeks, it's 10-12% of body weight per day, for 3 to 6 weeks, it's 8-10%, and from 6 weeks to weaning, it's 6-8%.

Practical Example

Let's consider a calf that weighs 45 kg and is 4 weeks old. Here, the feeding rate is 8-10% of body weight. So, the CMR needed would be approximately 3.6 to 4.5 kg per day.


Livestock Farming

Farmers can leverage this calculator to ensure each calf gets the right amount of nutrition, resulting in better livestock health and production.
