Crossbreeding with breeds that complement each other can help create a ranching operation the next generation can profit from, according to an animal scientist Extension specialist from the University of Nebraska. 

Passing on a viable ranching operation to the next generation is the goal for most ranchers, but passing on a ranch with just a love for cows is not the same thing, Matt Spangler tells producers. 


One way to create profit is by focusing on breed complementarity by crossbreeding. 

“True breed complementarity is a combination or merger of a breed that is strong in terminal strengths, like growth and carcass merit, with a breed or combination of breeds that are strong in maternal characteristics. The goal is to combine the terminal and maternal breeding systems,” he says. 

The majority of cow/calf producers sell some calves at weaning and keep some back for replacement heifers. 

“The problem with that is, we are leaving money on the table. The pervasive thought is one breed can do it all, and that is simply not true. There is not one breed out there that excels in all areas of profitability,” he says.

“It is also false to say one bull can do it all,” Spangler continues. “What if I said forget about maternal strengths and focus on terminal strengths or vice versa?” 

“The more traits we focus on, the less progress we make,” he explains.

Terminal traits

If a producer sells terminal calves at weaning and those calves excel in the same traits as the producer’s bull battery, then that producer is not maximizing profit, Spangler suggests. 

“Some would counter that is the way we have always done it, but that is not a valid argument,” he adds.

Terminal traits of importance are calf survival, male fertility, disease susceptibility, calving ease direct, growth rate, feed efficiency, carcass quality and composition. 

“If a producer selects bulls with a lower birthweight EPD for calving ease or selects bulls that have higher calving ease direct EPDs and they keep replacement heifers out of these bulls, there is a slight antagonism between calving ease direct and calving ease maternal,” Spangler explains.

He continues, “If they select for maternal calving ease over and over and over, there is a chance those daughters they keep back will have a harder time giving birth as a first calf heifer.”

On the other hand, if all the calves are terminal, meaning they were selected for terminal traits like hot carcass weight, yield grade and marbling, other negative effects can be seen, Spangler says. 

“If we use that index and keep back replacement heifers, we have just said we’re choosing bulls to breed females based on hot carcass weight, marbling and yield grade. Carcass characteristics are probably not the list we want to use to select females from,” he adds.


Genetic trends in the Angus breed, which means the average of the Angus breed, have made tremendous strides in yearling weight, hot carcass weight and carcass marbling, which are all terminal characteristics. 

“The way we think about breeds now has to be reflective of the breed averages we see today. A great example is mature cow weight. We used to think British breeds were conservative in size and continental breeds were large in mature size. Now, a lot of our British breeds have become a lot larger than the Continental breeds,” he says.


Ideally, small ranches should keep their replacement heifers separate from the rest of the herd, like larger ranches do. 

“The challenge is, does it make sense to sort 10 to 20 heifers out of the herd and manage them as a group and have to calve at night for that small of a number? We should ask ourselves if our time could be better spent elsewhere,” he tells producers. 

“I would argue that completely eliminating calving heifers could make the ranch more profitable and certainly more enjoyable,” Spangler says. “However, these smaller herds represent a larger fraction of sale herds in the U.S. But, there is room for improvement.”

For some producers, the solution may be as simple as implementing a system where one producer produces maternal replacements and another produces terminal calves and outsources their maternal replacements from the first producer.


Spangler sees breed means coming together, which hurts complementarity. 

“However, if we are a seedstock producer, there is nothing wrong with differentiating our cattle as maternal or terminal breeds,” he says. “Smaller cows may or may not be more efficient, but they can be more profitable bred to terminal sires.” 

“Trying to be all-purpose reduces efficiency and profitability. We can’t be all-purpose and maximize profitability. Selecting for fewer traits leads to faster progress in those traits we are selecting for,” he explains.

He referred to a quote from Burke Teichert, a cattle management consultant. 

“Let the imagination wander. What if smaller ranchers were to buy all their replacement heifers from a large ranch. The smaller ranch would never have to breed or calve a heifer, only cows. It would ensure cow size is small and allow breeding to a terminal sire to allow growth and carcass,” Spangler quoted. “All calves would then be sold with no replacements retained. The larger ranch is already breeding replacements and calving heifers, so why not breed a few more and sell some to the smaller ranch?”

The challenges of the beef industry extend into a wide array of issues, but John Kastelic, a veterinarian at the University of Calgary explains cattle production has changed in the last several decades, which means production must change slightly. 

“There are a lot of challenges in the beef industry,” Kastelic said. “We better be willing to move ahead and do things somewhat differently to meet those challenges.”

A look back

Historically, Kastelic mentions that beef cows calved in May, and their sons were sold at two years of age. 

“That has radically changed today. We’ve got cows calving earlier and earlier in the year,” he says. 

Additionally, many bulls are sold as yearlings, and as production sales are scheduled earlier, buyers select their seedstock earlier in the year. 

“Once people buy bulls, they stop going to bull sales, so seedstock producers have to be ready to sell earlier,” he continues. “It becomes a real challenge to get bulls to pass a breeding soundness exam early in the year so they are able to get into those early sales.”

Bull requirements

Kastelic explains bulls are expected to do several things during their lives. 

“A bulls has to identify cows in estrus, be able to mount those cows, successfully breed cows and deliver a large number of normal, fertile sperm,” he says. “If any of these are deficient, he will not be a functional breeder.” 

For example, if a bull has top-quality sperm motility, if he has a sore back and is unable to mount cows, pregnancy rates will be very low. 

Physical elements

One of the important considerations for bulls is related to scrotal circumference. 

“In general, larger testes produce more and better sperm, up to a scrotal circumference of about 35 to 37 centimeters,” Kastelic says. “We want to feed the bulls to reach genetic potential for testes size.” 

As a result, several studies have been conducted to demonstrate the impact of feeding on early bull development. 

“When we talk about developing testes, we need to talk about early versus later feeding and what we should and should not do,” Kastelic comments. “We want our bulls to be functional breeders for many, many years, so developing them is important.”


Kastelic says numerous studies have been conducted on the effects of feeding dairy bulls, and most of it was done after weaning, with limited work done in the early stages of bull development, so Kastelic’s team did a number of experiments to fill the void. 

“In this experiment, we fed three groups of bulls from 10 weeks to 70 weeks,” he explains. “These were beef bulls that were weaned early. We had one group who was fed a medium diet, which was our control group.”

The three experimental groups were low and high nutrition diets. Group one was fed low nutrition from 10 weeks to 26 weeks, and after that, half went on to a high nutrition diet and half went to medium nutrition. The third group was fed a low nutrition diet and, after 26 weeks, went to a medium-nutrition diet. 

The medium nutrition diet met 100 percent of requirements for both energy and protein, while the high nutrition diet met 130 percent of energy and protein needs. The low nutrition diet was only 70 percent of energy and protein requirements.

“All bulls received all the minerals and vitamins they needed,” Kastelic adds.


“Early on, we had a diversion in terms of scrotal circumference,” Kastelic says. “The bulls on low nutrition had testes that grew at a slower pace than were the bulls fed medium and high nutrition.” 

He continues, “The bulls that were initially fed on lower nutrition had a permanently lower scrotal circumference. Even the bulls that were put on high nutrition after 26 weeks, they never caught up to the other bulls.” 

Those bulls on a low plane of nutrition to 26 weeks, then fed a medium nutrition diet had the smallest testes throughout the study. 

“The bulls that were restricted early on had testes that were roughly 20 percent smaller,” Kastelic says. 


After the conclusion of the first study, a second study was conducted looking at one group of bulls fed a medium nutrition diet throughout the entirety of their lifespan, from 10 weeks through 74 weeks. 

“We had a second group, which we supplemented early on. They were fed a high nutrition diet from 10 weeks until 30 weeks, and then we had a medium nutrition after that,” Kastelic explains.

Again, in the second study, even though bulls were only supplemented to 30 weeks, high-nutrition bulls had larger testes across the board. 

“At slaughter, the supplemented, high nutrition bulls had testes about 20 percent larger, and perhaps more importantly, they had roughly 30 percent more daily sperm production,” he explains.

“By feeding bulls better early, we created bulls with larger testes that produced more sperm,” Kastelic summarized. “These effects remained, even though we went back to common nutrition after 30 weeks.”

Additionally, Kastelic noted that supplemented diets after 30 weeks had a limited effect on reproductive development, including a limited ability to overcome earlier deficits. 

“We need to feed our bulls really well prior to 30 weeks at the time when we can most influence them,” he says.

David Smith, an epidemiologist at Mississippi State University, says he largely studies infection diseases of cattle with the idea of trying to understand how to manage cattle to prevent problems. 

“Recently, we’ve been studying pneumonia in calves prior to weaning,” Smith explains, noting several management practices can impact pneumonia in calves. “I’m talking about work that’s been done by a large number of people.”

“The tradition in veterinary medicine is to think about a host-agent interaction,” Smith says. “Sometimes we think about what’s going on in the environment, but we often think about the bug and then ask if there is an antibiotic to kill it or vaccine to prevent the infection.”

He continues, “For pneumonia, we have to think broadly, because there are much broader issues that sometimes affect disease ecology.”

Disease challenges

When a calf is born, Smith says there are many hazards the calf faces between the moment it hits the ground and weaning.

“In the first few weeks of life, the calf’s big risks are the weather, injury, predators and disease,” he says. “From three weeks of age until weaning, the leading cause of death in calves is pneumonia.” 

Smith focused on pneumonia, opting to look at what goes on outside the animal that influences the risk in the herd to have the disease.

Disease agents

Further, when looking at the cause of pneumonia, Smith says all bacterial pathogens that may be connected to pneumonia are found in calves, including Mannheimias, Pasturellas, Histophilus, et cetera can be found. 

“We’re confident this is not necessary just a bovine respiratory disease (BRD) problem,” he says. “It may be present in some cases, but it’s not in all cases.” 

Further, Smith says they are suspicious about the role of bovine corona virus.

As antibodies are lost when the calf ages, Smith comments, “It doesn’t matter how high the antibody counts were, they’re gone by 90 days of age.”

While calves can also respond to disease after that point in time, prior to five to eight months of age, the immune response is slower, weaker and easy to overcome.

“There is a point in time when antibodies from colostrum are disappearing and the immune system hasn’t ramped up to full power,” Smith says. “That’s the time calves get sick.”

Risk factors

Smith explains his team looked for risk factors impacting sick calves, saying, “Those calves that got sick in the first 75 days were most likely to have a two-year-old dam for a mother. In fact, they were five times more likely to get sick if their dam was a two-year-old in the first 75 days.” 

Later illness was more likely to result in calves born to older cows. 

“We thought illness in calves before 75 days might have to do with lack of passive transfer in terms of colostrum in heifers,” he says. “Failure to receive colostrum puts calves at risk of pneumonia prior to 75 days of age.” 

  Rapid epidemics of sickness is often seen in calves that are between three and five months of age, Smith says, explaining, “These calves have lost their immunity all at the same time, leaving them more susceptible to disease.” 

“There are two patterns resulting from passive transfer of immunity, resulting in sporadic cases of disease in young calves and loss of immunity, resulting in larger outbreaks in calves that are 75 to 150 days of age,” he explains.

Environmental factors

Management practices, environmental conditions and more have implications on pneumonia in calves. 

“There was a positive association with the use of estrus cycle synchronization programs in cattle and pneumonia,” Smith says. “Producers who reported problems with pneumonia in calves also were more likely to say they use estrus cycle synchronization.”

Further, Smith adds, “They were also more likely to say they introduced calves from an outside source or that they offered supplemental feed to calves using creep feed.” 

Following the survey, Smith’s research team introduced a second study, randomly selecting control herds with less than half of one percent of calves affected by BRD and case herds, which treated more than five percent of calves treated for BRD.

Thirty control herds and 54 case herds were identified, and three factors were significantly associated with case herds, says Smith, including number of cows, whether intensive grazing was used and whether or not cows were synchronized for breeding. 

“The odds for a case herd increased with the size of the herd,” he says. “Herds that did intensive grazing were three times more likely to be a case herd, and the use of a synchronization program increased the odds that they had BRD was 4.5 times greater.” 

“We’re looking at pneumonia in calves prior to weaning as a childhood disease in cattle due to their age-related susceptibility because they’ve lost their colostrum and herd immunity,” Smith says. “Paradoxically, it seems to be associated with highly managed herds – larger herds following intensive grass and reproductive management.” 


To evaluate whether factors are important is determined by running calculations, which Smith’s team did. 

“In herds with 499 head with summer pneumonia, 71 percent of the risk is explained by herd size,” he says. 

Producer who do intensive grazing and have pneumonia can attribute 60 percent of the risk of the disease to intensive grazing. 

Finally, herds with BRD challenges that also utilize estrus synchronization can attribute 64 percent of their risk due to the synchronization strategy.

“Those are big numbers. They’re important,” Smith adds. “These three factors explain more than half of the occurrence of calf-hood BRD. Intensive management practices and larger herd size seem to be associated with BRD.” 

Explaining why

The reasons why intensive management and larger herds can lead to increased risk for BRD, according to Smith, is that the practices increase the opportunities for calves to be closer together.

“If we talk about a contagious pathogen, there are greater opportunities for one calf to share with another with these practices,” he explains. 

In particular, use of estrus synchronization can stress calves, also exposing them to dust and commingling them in pens for longer periods of time.

“As we tighten up the calving distribution and have more and more calves in a shorter period of time, they all become susceptible in a shorter window of time, leading to the sudden loss of herd immunity,” comments Smith. 

He continues, “The question for producers to ask themselves is, can we get the cost associated with summer pneumonia back by using estrus synchronization?”
