C-Lock delivers precision performance data for individual animals in beef and dairy cattle operations, as well as sheep, goats, and other small ruminants. Our systems measure the key performance metrics that matter most:
These measurements help you identify top performers, optimize feed efficiency, and maximize return on investment.
C-Lock's SmartLine and GreenFeed systems capture precise, real-time data for every animal. Our proprietary algorithms and scientific team ensure accuracy and reliability.
You receive clear, actionable reports that drive better decisions, improve performance, and increase profitability.
C-Lock transforms individual-animal data into actionable insights that reveal what's working and where to improve.
Our systems help you optimize rations, improve feed conversion, and eliminate waste—so every feed dollar delivers maximum value.
Feed is your largest expense. Measuring feed efficiency is how you control it.
A Feed Conversion Ratio (FCR) Assessment tracks individual feed intake and weight gain to calculate units of feed per unit of gain. This reveals your most efficient animals, highlights ration improvements, and cuts feed costs across your operation.
C-Lock's SmartLine products identify your top-performing cattle, sheep, and goats through precise feed efficiency data. Together, they solve the FCR equation—giving you the insights to make confident, data-driven decisions.
SmartFeed + SmartWater + SmartScale delivers proven, scalable feed efficiency tracking at the individual animal level. Whether used for genetics, nutrition, or economics, it provides the precision data needed to drive better decisions on-farm and in research.
GreenFeed transforms methane measurement from a research concept into routine, animal-level data. Producers and their advisors can evaluate feed strategies, document sustainability outcomes, and make decisions backed by hard numbers.
Efficient feeding of lactating cows is the biggest opportunity to improve milk yield and profitability. With feed representing over 50% of production costs, tracking Feed Efficiency Ratio (FER) is critical. SmartLine gives producers the tools to track, manage, and optimize feeding per individual cow.
SmartFeed transforms ration management from guesswork to data-driven feeding.
Producers gain:
| Feature | Livestock Producers | Dairy Producers |
| Key Objective | Maximize growth & reduce cost per lb of gain | Optimize DMI relative to milk output |
| Genetic Application | Bull selection for RFI & methane intensity | Selection of high-efficiency, low-CH₄ cows |
| Environment Type | Feedlot, backgrounding, or pasture systems | Confined dairies and controlled TMR environments |
| Efficiency Metric | Gain per kg of feed (FCR, RFI) | Milk per kg of feed (Feed-to-Milk Efficiency, RFI) |
| Emission Metric | CH₄ per kg of liveweight gain | CH₄ per liter of milk |
| Trial Duration | 70–120 days (feedlot or bull tests) | 305-day lactation periods (ongoing) |

GreenFeed is C-Lock’s flagship system for measuring Methane (CH₄), Carbon Dioxide (CO₂), and optionally Oxygen (O₂) and Hydrogen (H₂) from individual animals. Recognized worldwide as the global standard in enteric methane measurement, GreenFeed provides real-time, research-grade data for both scientists and producers.
Using a small amount of pelleted bait, animals are naturally enticed to visit multiple times per day, allowing GreenFeed to capture and analyze breath samples automatically. The system then processes this data into precise emission flux reports—making it easy to track, compare, and manage emissions.
SmartFeed is C-Lock’s automated feeding and data collection system designed to measure and manage individual animal intake. Using electronic identification, SmartFeed delivers precise feed portions to each animal, monitors consumption in real time, and records detailed intake data for analysis.
SmartWater is C-Lock’s automated system for tracking individual animal water intake and behavior. Using RFID technology, it records precise drinking events, frequency, and duration—providing valuable insights into animal health, hydration, and performance.
