Minimising weaning stress is one of the most critical aspects of rearing calves
Every change should be carefully planned and gradually implemented to avoid abrupt changes in feeding practices, such as removing milk or meal suddenly. Also avoid major changes in the environment (e.g. use the same paddock if weaning off milk outside onto pasture, and don’t wean off milk indoors and then abruptly put your calves outside into a foreign environment.
A calf’s rumen development is the most important factor to consider when making a weaning decision.
The only way this can be assessed is by measuring the amount of solid feed your calves are readily eating, which should be at least 1 kg of meal or 2 kg of pasture per day when commencing the weaning process.
