My approach to weaning calves is exactly like getting the biting point in a car – take your foot off the clutch too soon and you will stall. If calves are weaned too young or abruptly, it can have significant effect on their growth.
Calf pneumonia costs the UK cattle industry millions every year and is of huge financial significance. These losses arise from the cost of treatment, reduced weight gain, increased labour and most significantly from calf deaths. Calf pneumonia is one of the most common causes of illness and poor performance in housed calves from one to five months old.
