How we treat the calf, especially in its first few hours of life may have major consequences on how it thrives and performs later on in its life cycle. Calves deprived of colostrum are the calves that gain less weight, are more susceptible to scours and have higher mortality.


Some good tips are:

  • Use colostrum from the first milking for the first feed
  • Give colostrum within two hours from the calf’s birth
  • Give at least three litres of colostrum within the first feed
  • Feed colostrum at 15% of the calfs body weight

Below are some Colostrum feeding tips:

  • Try to get the calf to suckle 3 litres within the first few hours – as sucking stimulates an oesophageal groove within the calf’s body, allowing the milk to go into the abomasum chamber of the stomach where there is better absorption of nutrients. However, if this can’t be achieved, stomach tube the calf
  • Freeze colostrum within a few hours after first milking and if using at a later date thaw slowly at approximately 55°C
  • Do not feed waste milk to calves as it can lead to a higher bacteria load on the calf – which can contribute to diseases
  • Test colostrum quality by using either a refractometer or colostrum meter – looking for a reading of 50 grams/litre IgG


When looking at milk replacers you should be looking out for the following points:

  • Aim for a Crude Protein content of at least 23%, predominately milk derived proteins to help stimulate growth and muscle development
  • Oil level typically between 18 ‐ 20%
  • Fibre less than 0.2%
  • Ash less than 8%
  • Pre and probiotics


Concentrate feeding to the calf even from a young age is of major importance. Concentrates, rather than hay / straw are what gets the rumen development (main stomach of cattle) to occur within the calf’s stomach – due to its starchy element. With this in mind concentrates should be offered as early as 3‐4 days from birth.

Quick tips on concentrate feeding are:

  • Feed little and often i.e. 100 ‐200 grams per calf in the first week or two
  • Calf starter should have palatable ingredients – molasses, flaked maize and rolled barley
  • Crude protein is high i.e. 18% and derived from high quality protein (soya bean meal/full fat soya)
  • Every kilogram of concentrate consumed requires four litres of water


Roughage is important but at the same time not as important as concentrates ‐ concentrates have a bigger role in developing the calf’s stomach.

  • Calves need small quantities of forage i.e. hay/straw
  • Avoid feeding too much especially hay as it can lead to pot belly calves
  • Pot belly calves indicates that the calf’s stomach (rumen) is full of forage which isn’t fully digested
