The short version
- Each has a real cost: DairyComp the command language interface takes weeks to learn and effectively ties the dairy to whichever staff member knows it, so losing a herd manager can strand the herd record until someone else is trained.; Halter the subscription is permanent and per head, so a 500 cow dairy carries a five-figure annual bill indefinitely and the collars become inert if it lapses; there is no owned-outright end state.
- They diverge on capability: DairyComp covers Command language reporting, Halter covers Virtual fencing.
- Prices and features above were last checked on 1 September 2026.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
DairyComp
- The command language interface takes weeks to learn and effectively ties the dairy to whichever staff member knows it, so losing a herd manager can strand the herd record until someone else is trained.
- It is a Windows desktop application at heart rather than a cloud service, so multi-site access, remote working and mobile data entry are bolt-ons rather than native, and back-ups are the dairy's own problem.
- Zoetis ownership puts a pharmaceutical company in control of every treatment record on the farm and biases the integration roadmap towards Zoetis sensors and services rather than the best available.
- No pricing is published anywhere, so herd-size-based quotes vary by dealer and there is no way to benchmark what you are being charged without asking neighbouring dairies.
- It assumes North American dairy conventions, so European dairies dealing with different milk recording bodies, national herd databases and statutory reporting formats find the fit poor and often need local software alongside.
Halter
- The subscription is permanent and per head, so a 500 cow dairy carries a five-figure annual bill indefinitely and the collars become inert if it lapses; there is no owned-outright end state.
- On-farm tower infrastructure is a separate up-front install cost that is not in the headline per-cow price, and terrain with hills or bush can require more towers than the initial quote assumed.
- Coverage is concentrated in New Zealand, Australia and parts of the United States; buyers elsewhere face no local support, no local install crew and uncertain regulatory acceptance of virtual fencing.
- Virtual fencing is not universally legal or accepted: some jurisdictions and some organic or welfare certification schemes restrict aversive stimulus devices, which can decide eligibility before price is even discussed.
- Total vendor lock-in on collar, towers, app and animal data means there is no second source for a replacement collar and no way to keep the fencing working if the commercial relationship ends.

Answered from the vendors’ own pages
DairyComp: Who owns DairyComp now?
Zoetis, through its acquisition of Valley Agricultural Software. It sits in the same portfolio as the Smartbow cow monitoring system.
Halter: Do I buy the collars or rent them?
In practice you are buying into a per-cow monthly subscription plus a one-time install for the towers. The collars are not useful without an active subscription.
DairyComp: Is it hard to learn?
Yes, genuinely. It is driven by a typed command language rather than menus, and most new users need weeks of practice before they are productive.
Halter: What does it actually cost for 500 cows?
Starting from around NZ$9.90 per cow per month, that is roughly NZ$59,000 a year before the one-time tower infrastructure cost, and it recurs every year.
DairyComp: Does it run in the cloud?
It is fundamentally a Windows application. Hosted and multi-site arrangements exist but the software is not a browser-native cloud product.
Halter: Can I finance it?
New Zealand dairy farmers can finance the install through ANZ, ASB, BNZ or Westpac over two years, and paying the subscription up front attracts a discount.
DairyComp: What does it cost?
Nothing is published. Pricing is quoted per dairy based on herd size, plus separate charges for support and for each parlour or meter interface.
Halter: Does it replace heat detection collars?
Yes on the higher tiers. That is the main reason dairies justify the cost, because it removes a second per-cow system.
