Eurotier

Individual Animal Insights Built Around Increasing Profitability.

C-Lock Inc. builds precision measurement equipment for both cattle and dairy producers. Our systems record what each animal eats, what it weighs, and how efficiently it converts feed — in the barns, feedlots and handling facilities you already have. 

That data tells you which animals convert feed cheaply, which ones are costing you, and what to do about it. Built in Rapid City, South Dakota; running on farms and research stations worldwide.

STAND C03

SEE WHAT FEED BECOMES. C-LOCK INC. SEE WHAT FEED BECOMES. C-LOCK INC.

We Identify Your Top & Bottom Performers.

C-Lock scores every animal in the group it actually runs with — cows on income over feed, bulls and feeders on cost of gain — then ranks them top to bottom.

DAIRY · MEI Metabolic Efficiency Index

Two cows can eat the same ration, milk in the same parlor, and look the same in the alley — yet turn that feed into very different amounts of milk. Bulk-tank averages hide it. A per-cow number doesn't.

Nearly the same feed bunk. Very different milk out of it. $1,725-per-year swing between these two cows — and you can't see it from the alley.

BEEF · CGI Cost of Gain Index

Two bulls can eat the same ration, stand in the same test pen, and look the same over the rail, yet convert feed into gain at very different rates. That difference is heritable, and it rides straight into their calves.

Rank Your Herd with C-Lock.

Come to the stand and we'll walk you through what indexing your own herd would look like: every animal scored on efficiency, ranked top to bottom, and what that ranking changes about your breeding, culling and day-to-day management. It is the same conversation whether you milk cows or feed cattle.

QUICKFLUX

Rapid Phenotyping System

3–5 MIN PER ANIMAL
MEI SCORE · RANKED IN GROUP

QuickFlux scores individual animals on metabolic efficiency in 3 to 5 minutes, in the handling facilities you already have. The Metabolic Efficiency Index ranks your herd top to bottom, giving you measured data behind every breeding, culling and replacement decision.

Ranked top to bottom

Every animal scored against the group it ran with — not a sample.

No intake trial

No individual feed intake equipment and no test period to run.

Uses your current facilities

Headlocks, chutes, palpation rails, tie stalls. No installation, no site prep.

Watch a Live Measurement

Take a look at what a real, 3 - 5 minutes on farm measurement looks like.

Wheel it up and measure the animal where you already handle them.

What We'd Like to Talk About.

What your feed is actually costing you per animal — not per herd.

Two cows on the same ration convert it differently. On a herd average they look identical, and you keep paying for both.

Ranking your herd from your cheapest converters to your most expensive.

Measured intake and measured gain give every animal a cost of gain, ranked against the group it ran with. The bottom of that ranking is where your money goes.

Managing animals individually instead of by pen average.

Daily intake and daily body weight flag the animal that goes off feed before the pen average moves. Earlier action, fewer losses, less feed wasted.

Keeping and breeding the genetics that convert cheaply.

Feed efficiency is heritable, and it rides into the next calf crop. Breeding values need measured phenotypes in volume. We'd like to talk about what that takes.

Every Pound of Ration. Every Pound of Weight. 

Two pieces of hardware sit in the pen and do the counting for you. No chute work, no scheduled weigh days, no added labor. 

C-Lock SmartFeed unit — feed bunk with RFID head gate

SMARTFEED.

Individual feed intake 

Animals walk up and eat on their own schedule. The RFID reader identifies the animal, the bunk weighs the visit, and intake is logged to the animal — not the pen. Every meal, every day, automatically.

C-Lock SmartScale unit — walk-through weighing frame

SMARTSCALE.

Daily body weight 

Mounted in front of the water tank, SmartScale weighs every animal every time they drink. Daily body weight, captured without ever moving the animal — no chute, no shrink, no scheduled weigh day.
