Calf milk replacers (CMRs) are typically formulated from a range of lower-value milk products and may have reduced curding

Calf-rearing systems on dairy farms and specialist calf rearing units: results of a New Zealand survey
Calf-rearing practices were surveyed on 297 dairy farms with an average of 82 heifer and 24 bull calves reared. Only 21% of
the properties fed colostrum immediately on arrival at the dairy shed, and 30% did not feed their calves for at least 8 hours after
