🐂 Bulls, Bulls, Bulls: Why New Zealand Grazing Jersey Bulls Are the Smart Choice for Mating Season
Mating season is here again—cue the arrival of the bulls. We know the thought of them can stir mixed emotions. Your system is humming along, then suddenly, the eager-beaver lads turn up, ready to get to work. They may disrupt the calm on your farm, but let’s not forget—they play a critical role in setting up next season’s success.
Whether you’re a grower farmer managing the heifers or a dairy farmer managing your milking herds, the bulls are very important!
At New Zealand Grazing, we support our own New Zealand Grazing managed Jersey bulls in preference to dairy farmer supplied bulls.
✅ The Case for New Zealand Grazing Jersey Bulls: Reliable, Ready, Risk-Managed
Our company bulls aren’t just any bulls. These Jersey service bulls are bred, grown, and managed specifically for heifer mating under New Zealand Grazing’s care. Young Jersey bulls are renowned for having high fertility, perform better than average and produce smaller calves reducing the incidence of dystocia and delays in subsequent conception dates. Getting the milkers, especially first lactation heifers, back in calf as early as possible is a key to a successful next season.
They are:
✔️ Contract-bred from top-quality recorded Jersey dairy herds
✔️ Raised under New Zealand Grazing protocols by experienced bull growers, regularly weighed and handled
✔️ Fully vaccinated with complete health and treatment records
✔️ Full lifetime NAIT location traceability
✔️ Delivered to your farm in top condition—fit, and ready to work!
From birth through to your paddock, these bulls are part of a monitored, traceable, and biosecurity-focused supply chain. You know where they’ve been, how they’ve been handled, and that they meet New Zealand Grazing’s high standards.
⚠️ Dairy Farmer-Supplied Bulls: A Viable but Higher-Risk Option
We know some dairy farmers prefer to supply their own bulls for mating. While this is allowed, it comes with strict requirements—and extra responsibilities. It is only by arrangement and is for home bred bulls or for beef breed bulls.
Minimum Requirements for Dairy Farmer Supplied Bulls:
📋 Full vaccination and treatment history recorded on our Owner Supplied Bull Health Form and submitted a minimum of 10 days prior to bull delivery
🐮 NAIT-compliant with lifetime traceability – the sending farmer must action the NAIT movement
⚖️ Must meet minimum weight and condition score
🕓 Must arrive before mating begins (to settle in)
✅ Pre-approved by New Zealand Grazing
🤝 Grower must agree to accept the bulls- arrival of unsuitable bulls may mean they get rejected.
Even if these criteria are met, owner bulls still introduce unknowns—from inconsistent bull performance to increased biosecurity risks. New Zealand Grazing reserves the right to decline any bull that doesn’t meet our standards.
