2 lessons from calf-rearers
Calf-rearing is fraught with the risk of disease. Successful calf-rearers are acutely aware of all aspects of biosecurity.
Most have a rearing area specifically set aside for calves and young stock. If an unwanted organism is brought in, it’s isolated to that area, rather than spread throughout the farm.
Many calf-rearers use separate milk feed trailers for different mobs to prevent cross-contamination. They also use solid walls between the individual pens to prevent nose-to-nose contact.
