Calves

Calves must be born on or after 1st of July, hand reared and cared fro by the child entering Ag Day. 

Calves are best sourced from a local farmer. Buy a healthy calf that is at least 4 days old that has been well fed on colostrum. Look for small dry navels, pricked up ears, firm faeces, clear eyes, moist noses, shiny coats (breed dependent), firm teeth and playful movements. Colostrum can be purchased from a vet and can be kept frozen.

If a bull calf is chosen, he should be rung with a rubber ring within the first 3 weeks to become a steer, otherwise he may become aggressive as he reaches maturity. Ensure both testicles are down before releasing the ring when you ring the calf. Bull calves are not permitted for Ag Day.

Choosing a calf breed

Supplies and Gear required


Vaccination and Drenching

Your calf must be vaccinated for you to enter it in Ag Day.

 Your calf should be vaccinated with a 5-in-1 vaccine at six weeks of age and then given a booster shot at 12 weeks. This vaccine prevents Pulpy kidney disease, tetanus, black disease, malignant oedema and blackleg. Get in touch with Te Puna or Katikati vets for discounted pricing.

Drench for worms from 6-8 weeks old, unless otherwise advised by your vet. Pour-ons (down back bone - from base of neck to top of tail) are the easiest method. Other options are oral or injected. If applying pour-on, it is best to sit the calf on its tail and apply from the brisket to the groin to avoid the risk of hair loss or coat damage.

Lice Control

Lice are a common problem. The pour-on drenches also control lice, but it is necessary to brush the lice eggs from the coat. Keep infected calves and gear away from other calves.

Housing Requirements

A good clean, dry, and draught-free environment is required for optimum health. A bed of straw is ideal. A cover, even used only at night will assist your calf’s growth as it will not be using energy to keep warm. The cover will also keep the coat shiny and clean.

Daily Care

Regular feeding (twice daily for best growth)

Wash its face to remove any milk residue

Walk it on a halter and lead and spend time with it

Brush it at least once a day

Ear Tag Requirements - NAIT


De-horning

Certain cattle breeds will grow horns. These can be dealt with quite easily and inexpensively when the calf is young. A vet will come to your home and de-horn your calf using a hot electric torch to burn off the horn stubs. This is humane, quick and effective.

Alternatively there are de-horning pastes available from farming outlet stores or vets that need to be applied regularly over a period of time to remove the horn bud.
