C-Lock systems give cattle and small ruminant producers the ability to measure, manage, and optimize nutrition at the individual-animal level. By combining precise intake monitoring with optional intake control, our SmartLine and Pro systems help producers move beyond estimates and averages—making nutrition decisions based on what animals actually consume and how they respond.
Whether you’re evaluating supplements on pasture, fine-tuning backgrounding or finishing rations, or managing targeted nutrition for specific groups, C-Lock delivers the data and control needed to improve feed efficiency, animal performance, and return on feed investment.
With SmartFeed®, SmartScale®, SmartWater®, and Pro model systems, producers can:
Balanced Nutrition — No More, No Less
Deliver rations tailored to age, weight, physiological stage, and production goals, ensuring animals receive exactly what they need—without over- or under-feeding.
Reduced Feed Waste
Limit overconsumption and improve supplement efficiency, particularly during periods of high input costs or limited forage availability.
Improved Animal Performance
Support consistent growth in calves, maintain body condition in breeding females, and optimize finishing performance and marbling in feedlot cattle.
Data-Driven Nutrition Decisions
Replace assumptions with research-quality intake, weight, and performance data to confidently adjust rations and validate feed investments.
Precision Intake Control (Pro Models)
Set and enforce intake limits at the individual-animal level using automated headgates—ideal for limit feeding, targeted supplementation, and ration evaluation.
SmartFeed provides RFID-based precision feeding, recording individual animal intake down to the gram. This allows producers and nutritionists to see exactly how much feed, grain, supplement, or TMR each animal consumes.
SmartFeed removes guesswork from ration evaluation by showing true intake—not bunk disappearance.
SmartFeed Pro builds on intake monitoring by adding automated intake control. Using programmable headgates, producers can set maximum intake levels or restrict access entirely once an animal reaches its daily allowance.
SmartFeed Pro allows producers to manage rations, not just measure them.
Designed for grazing systems, SmartFeed® ULTRA delivers individualized supplementation in open pasture environments.
SmartFeed ULTRA bridges the gap between precision nutrition and pasture-based management.
SmartScale provides walk-on, low-stress weighing, capturing frequent body weight data without animal handling.
SmartScale turns intake data into measurable performance outcomes.
Water intake is a critical—but often overlooked—component of nutrition. SmartWater® systems measure individual animal water consumption, while Pro models allow for controlled access.
C-Lock’s GreenFeed system complements intake and performance data by measuring individual animal emissions. This allows producers and researchers to evaluate how different rations, supplements, and feed additives impact both performance and environmental outcomes.
By pairing GreenFeed with SmartFeed and SmartScale, producers can:
GreenFeed helps close the loop—connecting what animals eat with how they perform and emit.
C-Lock systems give dairy producers the ability to measure, manage, and refine nutrition at the individual-cow level. By capturing precise feed intake, body weight, and water consumption—and pairing that data with optional intake control—C-Lock enables smarter ration decisions across all stages of production.
From transition cows and high-producing lactating cows to growing heifers and dry cows, C-Lock systems help producers move beyond pen averages to understand how each cow is consuming feed and responding to the ration. With this insight, nutrition programs can be adjusted with confidence to support milk production, reproductive success, animal health, and long-term profitability.
Optimized Ration Delivery
Align nutrient supply with milk production demands, stage of lactation, reproductive status, and health needs—ensuring cows receive the right nutrition at the right time.
Improved Transition Success
Closely monitor intake, body weight, and behavior during the critical pre- and post-fresh period to support smoother transitions and reduce metabolic disorders.
Reduced Feed Waste
Improve feed and supplement utilization by minimizing overfeeding and targeting nutrients where they deliver the greatest return.
Precision for Profitability
Make data-backed ration adjustments that support milk yield, feed efficiency, animal longevity, and overall herd performance.
Individual-Level Insight
Move beyond group averages to identify intake variation, underperforming cows, and opportunities for targeted intervention.
SmartFeed delivers per-cow intake tracking using RFID identification a
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.
SmartScale is C-Lock’s advanced weighing system designed to automatically capture individual animal weights with precision and minimal stress. Using RFID technology, animals are identified and weighed as they pass over the scale, allowing for continuous, hands-free data collection.
