There are four main parameters to determine weaning time with artificially reared dairy-bred calves: age, liveweight, concentrate intake and milk price. Most commercial calf rearers use concentrate intake as the main method weaning calves when eating 1kg of concentrates per day. Calves can be weaned either abruptly or gradually where the quantity and strength of milk replacer is reduced over a period of time. The objective of this experiment was to evaluate the effect of gradual or abrupt weaning strategies for calves weaned at 42 days of age.
