Selecting and Maintaining Cattle Replacements 

Selecting and Maintaining Cattle Replacements

Selecting and maintaining replacement heifers is the future of the herd, building on the best of what your genetics have to offer and hopefully carrying that on to the next generations of terminal and replacement animals. But breeding up or even maintaining the quality of your genetic pool doesn’t happen by accident.

Heifer replacements and breeding goals go hand and hand. Having breeding goals can help you further develop what the heifer replacements should look like or what the standard is.

A big part of developing a heifer replacement program is to understand bull selection and if and when a herd bull is appropriate for furthering your replacement program. Another big portion of having influential and strong replacement heifers is managing them and raising them to be just that. All of these decisions then need to fit into the budget and provide a positive return on investment (ROI).

Breeding Goals

The cow-calf operator is in a bit of a delicate balancing act when making mating decisions. Terminal traits are extremely important to focus on, but they must counterbalance with strong enough maternal influence.

Of course, needs will look differently for herds also relying on purchasing part of their replacement animals. Environment, operational and managerial values and local market may all factor in.

When determining a replacement heifer objective, we want to make sure we are improving the overall herd genetics. This might include selecting for improved fertility (such as daughters from cows that conceive first and calve early in the season), better udder quality and teat structure, increased longevity, moderate mature size for efficiency and structural soundness that supports better longevity and productivity. In some operations, producers may also prioritize traits like feed efficiency or adaptability to specific environmental stressors such as heat tolerance, parasite resistance or forage limitations.

Bull Selection

You can’t discuss the quality of your replacements without mentioning the bull who is contributing fifty percent of their genetic material. It goes without saying that there should always be a strong focus on economic and carcass traits. But in the case of bulls that will sire heifers who will be around for many years, there are a few additional considerations.

Of importance are structural and behavioral traits. Structural soundness—particularly feet and legs—directly impacts a female’s ability to graze, breed and remain productive over time. Likewise, health traits such as udder quality and overall durability are moderately heritable and play a role in longevity.

Temperament should also not be overlooked. Not only are docile females easier to handle, but they are also more likely to pass that disposition on to their offspring. Research demonstrates that calmer cattle tend to have improved average daily gain and feed efficiency, as less energy diverts toward stress responses and more toward growth and muscling.

It is also widely accepted that scrotal circumference in bulls is correlated with reproductive performance in their daughters. Bulls with larger scrotal circumference EPDs tend to sire daughters that reach puberty earlier and have improved lifetime fertility.

Replacement Heifer Management

Select and separate Replacement heifers from the herd at weaning or shortly thereafter, often around six to eight months of age, depending on the operation and management system.

Before physically examining animals, go in having a short list of your most desirables according to the EPDs if you have them. There are a multitude of ways to rank and analyze them to allow for the best decision making. But generally, you want to include fertility, calving ease, growth, and maternal traits. From there, you can evaluate based on the phenotype you’re observing and further thin them out if necessary by removing any that lack body capacity, appear unthrifty or have significant structural issues that may impair mobility or future calving ability.

For purchasing heifers, you want to know health status such as vaccination history, disease resistance, and parasite control and make sure it can be incorporated into your herd. When it comes to heifer replacements bred on the farm, it is additionally important to have a vaccination program. For a breeding heifer purchase, you may require a pre-breeding evaluation.

Raising a healthy heifer means having a solid and developed nutrition program which can look differently depending on location and resources available for the rancher. No matter the environment, a good nutrition program is foundational to raising healthy and productive replacements.

Generally speaking, a ballpark breeding age for first calf heifers is 12 to 15 months assuming that they reach approximately 60 to 65 percent of their expected mature body weight at the start of the breeding season.

At this stage of growth, conception rates should be monitored closely to confirm if these replacements are worth retaining for the duration of their productive lives. Not having to rebreed or AI multiple times, even if imperfect, always helps the bottom line.

Once again, the health program may look different for a purchased animal vs a home bred and raised heifer. Both should have a vaccination schedule and for animals purchased, they should have records that you can include in your record books.

Finally, biosecurity practices for your herd and farm are pivotal to keep calves healthy. Bringing new animals in should go through a quarantine process before joining the rest of the herd.

Some of the Economics

Economics drive most decisions on the farm or ranch, and keeping good records of the breeding program and the tied financials can help determine if your replacement heifer program is being cost effective.

There is a lot that can go into the economic portion, including individual animal ROI. A cow that remains productive for several years by calving regularly and weaning a healthy calf spreads out her development and maintenance costs over time, making her significantly more profitable than one that leaves the herd early.

Part of a good replacement is being able to provide longevity and continue to be productive through that time.

Once management costs increase and productivity starts to fall off for an animal, it might be time to make a cull decision. Understanding this can help you determine how you want to implement your replacements and also a cull program.

For some, providing all the replacements may not be feasible, but purchasing replacements may be beneficial to the herd setup.

Return on investment in a replacement heifer program is largely driven by development costs, reproductive success, longevity, and calf performance. Studies have shown that it can take two to three calves before a heifer has paid back her initial development cost, meaning early culling or reproductive failure significantly reduces profitability. Heifers that conceive early in the breeding season and calve early tend to remain more productive over their lifetime, weaning heavier calves and generating more cumulative revenue. Additionally, controlling input costs—feed, health and labor—while maintaining performance is key to maximizing ROI.

It is additionally important to understand the market conditions and how that would impact replacements in addition to herd expansion and contraction decisions. In stronger cattle markets, retaining more heifers may make sense to expand and capture future revenue, while in tighter markets, stricter culling and selective replacement strategies may be necessary.

Building a Better Cattle Handling Setup

Building a Better Cattle Handling Setup

Working cattle is never just another chore on the list, it takes some serious time dedication, planning, and a little bit of cooperation from your cattle, or calves. Having the right cattle handling setup can make the difference between a smooth day and a stressful one. Some days it goes smooth, where cattle flow easy, gates swing right, and you finish before you know it. Other days, it feels like everything fights you, including mud on your boots, a stubborn cow at the gate, and it causes more stress than it should take.

Design Matters

Most ranchers will tell you that those long days usually trace back to the setup. When your facilities work with you and with the cattle, the job finishes safer and faster. Hi-Hog has been building and designing cattle handling equipment setups since its incorporation in 1974. We were able to speak with Myron Wigness from Hi-Hog Farm & Ranch Equipment about some tips and advice when it comes to designing your set-up. One of Wigness’s top recommendations when evaluating design is to choose something versatile that fits your specific operation. As he explains, “We try to develop a line that’s very versatile. There are very few situations that we even have to build special equipment to fit, even if it’s into a restricted area, like a vet clinic.” Having a versatile design will give you flexibility and functionality for future growth and needs.

MJE Livestock Equipment is designed and tested in demanding environments to withstand heavy, everyday use, which gives customers confidence in its durability and performance. In a previous American Cattlemen Podcast episode, we were able to sit down with Ethan Cantrell with MJE Livestock Equipment. He sheds some light on the importance of design. He states, “You want to make sure you’re working with the cattle flow. If they’re moving with you instead of you fighting them, there’s a lot less stress for everyone.” When they don’t, you feel it in your back, your time, and sometimes your bottom line. (To listen to the full podcast about MJE and design go to: https://americancattlemen.com/podcast/mje-livestock-equipment-cattle-con-2026/)

How that job goes often depends on the setup more than anything else. A well-designed handling system can turn a long, stressful day into a smooth and efficient one, while a poor system can lead to frustration, injury, and lost performance. Research from universities and animal behavior experts has shown that cattle handling setups are not just about equipment, but about how that equipment works with the natural behavior of the animal. When design and behavior align, both cattle and handlers benefit.

Another option to consider is if you need a portable model. Choosing where and how you’ll use your equipment is key, and for many operations, a portable setup offers the most flexibility. John McDonald developed the Rawhide Portable Corral after years of working with cattle and hauling rodeo arenas across the country. His goal was to create a system that was quick and easy to use in remote pastures. As he explains, “When I first invented the Rawhide, it was out of necessity,” says John McDonald. “I was doing somethings with livestock in isolated pastures and we were set up like most people—namely with portable panels. My initial objective was just to be able to set something up that was not labor involved or labor intensive and to catch whatever I needed to and go on with my day.”

Today, the Rawhide line includes multiple models. The Original serves as a basic catch-pen system with quick, low-labor setup and options sized for different herd numbers, while the more advanced Processor model adds features like a head gate, adjustable alley, and loading chute to handle a wider range of livestock needs.

Low-Stress Handling

Cattle remember fear, and Temple Grandin, is one of the industry’s most respected researcher when it comes to cattle and cattle handling equipment. Studies led by researchers like Temple Grandin at Colorado State University have shown that cattle respond strongly to fear and past experiences. Cattle that are handled roughly become more difficult to manage over time. Their research also shows that while cattle that are handled calmly tend to move more easily and show less stress.

This is not just about convenience; stress has real effects on profit. Research has found that highly stressed cattle can take 20 to 30 minutes for their heart rate to return to normal after agitation, and repeated stress can reduce weight gain, weaken immune response, and hurt reproduction. This means that equipment design should be to minimize stress and fear. Curved alleys, solid-sided chutes, and smooth transitions all help cattle move more naturally because they limit distractions and take advantage of herd behavior.

Closely tied to cattle behavior is the concept of low-stress handling. University and industry research has consistently shown that reducing stress improves both animal welfare and production outcomes. In one review of livestock handling systems, researchers noted that cattle exposed to lower stress return to feed more quickly and experience less sickness, which directly impacts profitability.

Equipment that supports low stress, such as properly sized alleys and well-designed crowding areas, makes it easier for handlers to apply these principles consistently.

Safety

Safety is another major factor that cannot be overlooked. Cattle are large animals, and even a calm animal can cause serious injury if the setup is not designed correctly. Research and extension programs have long emphasized the importance of escape routes, solid gates, and proper chute function. Poorly designed systems increase the likelihood of handler injury, especially in tight spaces or areas with poor visibility. The Center for Disease Control estimates that the average non-fatal ranch injury costs a little over $15,000 in medical expenses and lost time from work.

If you can limit the amount of time that you have to be in the pen with cattle, you can increase your safety. Ray Sturn, Moly Manufacturing Plant Manager, illustrates how Moly Manufacturing’s TurretGate helps minimize contact with cattle. He says, “The inspiration for came from Moly Manufacturing founder Jon Mollhagen’s childhood experience with traditional crowding gates, particularly the danger of gates kicking back on him and the intense pressure created when people are forced to work inside confined spaces with cattle. Gates have always been the number one hazard, and crowding animals in high-impact areas only increases risk for both people and livestock.”

He continues, “Even with hydraulic gates, the fundamental problem remained: operators still had to push gates into oncoming animals. The breakthrough came with the shuttle function, which allows the crowding gate to roll back through the turret. This design lets cattle move with the flow instead of forcing them against it, eliminating the need to push a gate into animals altogether.”

While working cattle, cattle can be unpredictable as their flight or fight instincts kick in. Sturn says, “Traditional systems also require people to stand inside the tub or alley, with cattle behind them. In that situation, the person becomes the prey – animals are trying to escape while being pressured from behind and driven toward the same alley. TurretGate changes this dynamic by allowing shorter alleys behind the crowding gate, reducing pressure, and creating calmer movement.”

As Ethan Cantrell with MJE Livestock Equipment says “A bunch of these operations we work with are family businesses. We want the whole family out there, we want everyone feeling safe.” At the core, safer facilities reduce accidents. A well-built chute that holds an animal securely not only protects the handler but also reduces stress on the animal by preventing excessive movement.

Just as you should consider your design and layout, you should consider your available labor and help. Operations with limited or no assistance need setups that reduce workload and prioritize safety for both the handler and the animals. As Myron Wigness with Hi-Hog notes, “During calving season, a lot of times, you’re stumbling around out there in the dark by yourself. So, safety is a big concern. We try to keep even someone that’s working alone safe.”

So, consider the safety of you, your help, and the stress on the cattle. Set your pens up so cattle want to walk through with minimal balking and distractions. It’s safest for you if you can minimize your direct contact with cattle.

Invest in Quality Equipment

Efficiency is another area where equipment design plays a key role. Studies on cattle flow have shown that animals move more easily through systems that are designed with their natural behavior in mind. Cattle prefer to follow one another and avoid sharp contrasts in light, shadows, or sudden changes in direction. When ignoring these factors, cattle tend to balk, bunch up, or turn back, which slows down the entire process. In contrast, systems with smooth flow can significantly reduce labor needs. Producers often report being able to work cattle with fewer people when facilities are properly designed, and this aligns with research showing that calm, steady movement reduces handling time and stress.

At the center of any handling system is the equipment itself, including chutes, headgates, alleys, and crowding areas. Each component plays a specific role, and research supports the idea that these parts must work together as a system. For example, a well-designed chute that applies even pressure can help calm cattle during restraint, which is why squeeze chutes are widely used. Observations and behavioral studies have shown that some cattle actually become calmer when held securely, as the pressure can reduce anxiety. At the same time, poorly designed equipment that causes pain or discomfort can create negative associations, making cattle harder to handle in the future.

Choosing your System

One of the most discussed topics in cattle handling today is the choice between a Bud box and a crowd tub. While there is a limit to formal research directly comparing the two, both systems are based on well-established behavioral principles. A crowd tub uses a circular design to guide cattle forward, while a Bud box relies on the animal’s instinct to return to where it came from. The success of either system depends heavily on proper use. Research on cattle perception and behavior shows that animals respond differently based on their previous experiences and how they interpret their environment. This means that even the best system can fail if it isn’t in use correctly, while a simpler system can work well in the hands of a skilled handler.

Another important consideration is whether to use portable or permanent equipment. The choice depends on operation size and management style. Portable systems offer flexibility and are useful for operations that handle cattle in multiple locations, while permanent systems allow for more precise design and often greater durability. The key is to match the system to the operation, ensuring that it supports efficient and low-stress handling.

Durability and material quality are also critical factors. Equipment that breaks or fails during handling can create dangerous situations and increase stress for both cattle and handlers. Investing in strong materials, solid welds, and proper coatings to prevent rust can extend the life of equipment and reduce long-term costs.

Upgrades are Investments

Cost is often one of the biggest concerns for producers, and it is important to look at equipment as an investment rather than just an expense.  Cantrell suggests producers look at upgrades as investments rather than unnecessary expenses. When it comes to upgrades, Cantrell explains, “It’s a big investment and something they’re going to use to keep their business going”.

Research has shown that stress and poor handling can negatively impact weight gain and meat quality, which directly affects profitability. When viewed in this context, higher-quality equipment that reduces stress and improves efficiency can provide a strong return over time. For example, calmer cattle are less likely to experience bruising and less weight-loss from stress. These losses can add up quickly, making it worthwhile to invest in better facilities.

Ray Sturns illustrates how upgrades can help with both animal and handler safety. He states, “Most conventional crowding systems are antiquated, relying on human presence inside the animals’ flight zone to function. Even standing outside a swinging gate still puts the operator in that flight zone, which creates unnecessary pressure and unpredictability.”

Use Modern Tech to Further Advance

Sturns goes on to highlight how upgrading your gates can keep handlers safe and reduce injury risk. He says,TurretGate replaces that inefficiency with a safer, more humane process. Operators receive training to stay out of the tub entirely and use a remote control instead. By avoiding the flight zone altogether, cattle move more naturally, reducing stress, virtually removing the need for people to be in with the animals. Our customers always tell us that adding the TurretGate to their current system reduced the physical exertion of two people while working cattle, and has also eliminated their labor needs by two people – that’s a big savings to any operation.”

Modern technology is also playing a growing role in cattle handling. Hydraulic chutes, electronic scales, and data tracking systems are becoming more common, especially in larger operations. They can improve efficiency and reduce physical strain on handlers, and also reduce the amount of labor needed to work cattle. Technology also allows producers to collect more data, which can be of use to make better management decisions over time.

Final Thoughts on Building Better Cattle Handling Setups

Finally, the overall layout of the facility is just as important as the cattle handling equipment setup itself. Research and extension recommendations consistently emphasize the importance of proper layout, including good drainage, thoughtful placement of pens and alleys, and consideration of environmental factors like wind and sunlight. Poor layout can create muddy conditions, increase stress, and slow down cattle movement, while a well-planned system can improve both efficiency and animal welfare.

In the end, safe cattle handling starts with handlers, and design. When it comes to cattle handling equipment, creating a system that works with the natural behavior of cattle, supports handler safety, and improves overall efficiency is key. Industry experts make it clear that low-stress handling has real, measurable benefits for animal health, performance, and profitability. By focusing on behavior, design, and long-term value, producers can build systems that make cattle work safer, smoother, and more productive for years to come.

CERES TAG and Think Digital Partner to Deliver Biosecurity

CERES TAG and Think Digital Partner to Deliver AI-Powered Biosecurity Detection and Response

Cattle producers are set to benefit from a powerful new capability in livestock biosecurity surveillance, detection and response with a collaboration between CERES TAG and Think Digital’s RemoteVet ai platform.

This partnership brings together CERES TAG’s direct-to-satellite livestock monitoring technology with Think Digital’s RemoteVet mobile application to provide producers with a comprehensive, end-to-end biosecurity solution. The combined platform enables early detection and monitoring of serious biosecurity threats, including New World Screwworm (NWS), Foot-and-mouth disease (FMD), Lumpy skin disease (LSD), and Buffalo fly, with the flexibility to expand to additional risks.

CERES TAG’s plug-and-play, direct-to-satellite solution requires no on-ground infrastructure, delivering real-time GPS location and behavioural insights from livestock in even the most remote environments. The system continuously monitors each animal and provides daily reporting across key metrics, including eating time, rumination, walking, resting, drinking, and total grazing time, alongside high and no-activity alerts that can indicate distress, illness, or mortality.

How the RemoteVet App Works

By analyzing these behavioral patterns alongside location data, producers can identify significant deviations that may signal the onset of a biosecurity event, often well before it is detectable through conventional inspection methods. While traditional passive monitoring systems can take up to six days to detect an active incursion, CERES TAG enables detection within 24-48 hours, dramatically improving response time and reducing the risk of spread.

Once an alert is triggered, producers can use the RemoteVet mobile application to assess the animal in the field. Using the forward facing camera on a mobile, the user can capture a photo of their animal. The app’s AI engine then analyses the image, highlights areas of concern, and returns a confidence-based assessment of the likely condition. Producers can then choose to notify their veterinarian, biosecurity authorities, or both, ensuring rapid escalation, expert validation, and appropriate action.

This integrated approach reduces the burden on producers to make high-stakes decisions while enabling veterinarians and authorities to prioritise resources more effectively. It also introduces a “no-fault” pathway for escalation, supporting faster reporting and improved overall biosecurity outcomes.

Industry Leaders Highlight Benefits of RemoteVet

Kat Bidstrup, CEO of Think Digital, said that providing producers with useful tools to help detect and report biosecurity concerns is the key driver of the partnership.

“Workers on the frontline need practical support to identify and triage unfamiliar conditions in their livestock. We know early detection and response is key to preventing widespread outbreaks that could devastate our livestock industry.

“We’re excited by the potential of this partnership with CERES TAG to improve biosecurity preparedness.”’

David Smith, CEO of CERES TAG, said the partnership represents a step-change in how the industry manages biosecurity risk.

“Compulsory culling of livestock in infected or adjacent zones, regardless of individual animal status, has historically resulted in significant and often unnecessary losses,” he said. “With this capability, we can move toward more accurate and time-sensitive assessments, potentially saving millions of animals during an outbreak.

“We now have the ability to remotely detect, monitor, and assess biosecurity risks in near real time, providing producers, veterinarians, and authorities with the confidence to act early. This can be the difference between losing entire herds and preserving valuable livestock.

“Too much has been lost in the past. By combining CERES TAG with RemoteVet.ai, we are creating a pathway for governments and industry to adopt digital detection systems that reduce risk, protect supply chains, and safeguard billions of dollars in economic value.”

RemoteVet.ai is now available alongside CERES TAG for integration into government and industry biosecurity frameworks, supporting proactive risk management and faster response capabilities across the livestock sector.
