On many dairy farms, milk replacer plays a vital role in the calf-rearing process. It aids in calf development and growth performance.

At birth, calves are monogastric, which means they obtain all their nutrient requirements from milk or milk replacer.

During the calf-rearing process, the rumen develops and they become ruminants.

Milk replacer

On most farms that use milk replacer it is introduced to calves at about three days of age.

Generally, this is after the calf has received colostrum and a number of feeds of transition milk.

It is important that calves receive adequate amounts of colostrum soon after birth; for this, farmers should follow the 1,2,3 rule.

Using the 1,2,3 rule:

  1. Use the first milk (colostrum) from the cow;
  2. Feed the calf colostrum within the first two hours of birth;
  3. Calves must be offered at least 3L of good-quality colostrum.

Feeding milk replacer has a number of benefits, with the reduced risk of spreading disease a major one.

When herds have, or might have Johne’s disease-positive cows, whole milk should not be fed to calves.

Johne’s disease is caused by the bacterium Mycobacterium avium subspecies paratuberculosis (MAP) which affects cattle and other ruminants.

MAP bacteria can be spread from one animal to another by feeding infected milk, along with a number of other potential diseases.

Using a milk replacer offers calves protection from these diseases. But if you feed calves whole milk or milk replacer, it is important that the calf is provided with energy and protein which is critical to support and maintain their normal bodily functions.
