Feeding the young calf

A key focus of the calf rearing period is to stimulate the rumen to start growing and developing prior to weaning off milk. Nutritious and health-supporting milk and a good quality starter feed are key components of a successful calf rearing system and can help take some of the stress and risk out of calf rearing.

After good colostrum intake has been achieved in the first day of life, milk becomes the most important source of nutrients for a calf. Feeding calves transition milk from the first milkings and waste milk from treated cows carries the risk of transmitting Johne’s, salmonella and other diseases such as Mycoplasma Bovis. These and other animal health concerns help to justify the use of well formulated calf milk replacer beyond a simple cost price advantage.

Starter feed
Offering a palatable, high protein, grain based calf feed as early as day 5 is the key to kick starting rumen development and stimulating dry feed intake in preparation for a grass based diet.

Top tips for hard feed intake
Choose a high quality, mineralised and vitaminised starter feed – ideally with no palm kernel. A key attribute should be a low dust feed with a great taste and mouth feel, as calves don’t like eating fines. Recent improvements to the NRM Moozlee formulation means it is now an even better choice for those who prefer to offer young calves a textured feed, with the added benefit of lucerne chaff for a great taste and to help clean developing rumen papillae.

  • Always make sure the feed on offer is fresh and only put as much into troughs as calves will eat between milk feeds.
  • Calves maintain a lot of mouth activity after a milk feed – hand feeding young calves some hard feed immediately after their milk feed can help get them used to the texture and flavour.
  • Calves can be exposed to coccidiosis from an early age, so feeding a hard feed with a proven coccidoistat such as Bovatec can help prevent a debilitating or even deadly parasite taking hold – but remember to keep away from dogs and horses who can be killed by ingestion of coccidiostats.
  • Always have fresh water available – water is critical for hard feed intake.
