Animals showing clinical signs of, or have been diagnosed with a disease or illness, must be removed from the main milking herd, marked and recorded, and their milk withheld from the bulk milk tank until the clinical signs have been resolved.
Prompt treatment of sick and lame cows is best for the cow’s welfare and will also mean there is less of a drop in milk production. It is also illegal in New Zealand to milk sick cows for food production and they must be treated as soon as possible to fulfil the requirements of the Animal Welfare Act.
The benefits of paying attention to dairy health include:
- Ensuring the disease is not transferred to the rest of the herd with early intervention.
- Prevent animal health problems.
