Episode: Breed Diversity, Heart Disease, Import Export

Overview

This episode brings together veterinary and industry experts from the Beef Cattle Institute at Kansas State University to explore key issues impacting today’s beef industry. The discussion covers three main topics: managing breed diversity in commercial herds, recent findings about heart disease prevalence across livestock species, and the complexities of cattle import and export—both practical and political.

Main Topics & Key Insights

1. Breed Diversity: How Much is Too Much?

Listener Question:

• "If I already have a two-breed cross, should I add a third breed to my herd to get more heterosis, or is there such a thing as too much breed diversity?"

Key Discussion Points:

• Benefits and Risks of Heterosis.
  • Heterosis (hybrid vigor) is valuable for improving fertility and performance, especially when crossing genetically distant breeds (e.g., Bos indicus x Bos taurus).
  • “The biggest amount of heterosis comes from breeds that are most diverse in their genotype.” – D, 04:08
  • However, too many breeds can complicate management and dilute desired traits.
• Breed Complementarity:
  • Combining breeds should not only maximize heterosis but also bring together complementary traits (fertility, growth, carcass quality, etc.).
  • “The breeds have to complement each other. ... That's why a lot of times people like a two-breed cross because it's probably the easiest to manage.” – C, 06:13
• Genetic Management & Practicality:
  • Effective record keeping and clear breeding goals are vital, especially when attempting more complex, multi-breed systems.
  • Consistency in output/product is often easier with a two-breed cross.
  • “If you are going to try and select for certain traits, you need to have the tools in place to monitor and measure those traits accurately.” – B, 06:43
• Industry Trends:
  • Over 30 years, breed differences have narrowed due to shared selection targets (feedlot performance, carcass quality), so focusing on individual animal diversity may sometimes offer more benefit than simply adding breeds.

Notable Quotes:

• “There can be some downsides of trying to cross breed and just if our focus is heterosis and not maximum production.” – D, 05:03
• “When you add another breed, you have the potential to have cows within the same herd that have a pretty different breed makeup. ... You want a consistent product.” – C, 09:17

2. Heart Disease in Livestock: Surprising Prevalence & Species Differences

Recent Study Discussed:

• Survey of heart lesions in slaughtered livestock (cattle, pigs, sheep, goats) in the Czech Republic
• Highest prevalence: Piglets (14%), finisher pigs (8%), adult cows and calves (lower but present in all groups)

Key Discussion Points:

• Understanding Heart Disease:
  • Not a single condition, but a group (valvular, muscular, infectious, left/right-sided issues).
  • The heart compensates well until late-stage disease, so slaughter findings often reflect compensated, chronic disease.
  • “There can be a lot of different causes of heart problems, and the body does compensate as long as it can, but that's why...sometimes it goes south really fast.” – C, 12:23
• Production Focus vs. Animal Health:
  • Commercial selection is for rapid growth, not athleticism or heart health—potentially increasing heart stress or vulnerability, especially in pigs.
  • “We’re not selecting for food animals to become athletes. ... That trade off might be at the expense of heart function.” – B, 13:12
• Study Methodology Limitations:
  • The paper only examined hearts; full clinical relevance (e.g., by examining correlating organ changes) isn’t clear.

Notable Quotes:

• “Heart disease is not one disease. You can have problems with the heart valves, you can have problems with the heart muscles ... So it shouldn't really be surprising that we could have those types of problems.” – C, 11:43

3. Import/Export of Cattle: Benefits, Risks & Policy Dilemmas

Context:

• Recent border closures due to New World Screwworm concerns; bigger picture of animal health versus economic policy.

Key Discussion Points:

• Economic Interests Along Supply Chain:
  • Limiting imports often benefits cow-calf producers in the short term (higher prices), but can disadvantage feeders, packers, and consumers.
  • “If you can keep animals out of the country ... put an upward pressure on prices at the cow-calf level.” – E, 15:09
  • “Short term benefits don't always become long term benefits.” – C, 18:59
• Animal Health and Biosecurity:
  • Disease prevention (like screwworm) justified current border closures, but paradoxically, inspected cattle at official sites are less likely to transmit disease than smuggled or uninspected animals.
  • “Maybe the least likely cattle to cross the border with this disease ... are the ones that come through the inspection sites.” – C, 16:03
• Trade Complexity & Unintended Consequences:
  • Closures affect not just live cattle trade, but can trigger retaliatory trade barriers in other commodities (beef, pork, cars).
  • Loss of feedyard profitability cascades, potentially reducing future calf demand and harming cow-calf producers long-term.
  • “In all of these types of discussions, it's important to remember that there are second order, third order ... effects.” – B, 17:57
• Exports’ Critical Role:
  • The US exports 10-15% of its beef (especially organ meats not consumed domestically), adding $400+ per head to income.
  • “According to USMEF, I think about $425, $450 per head is result of export markets.” – E, 20:21
• What Can Producers Do?
  • Direct control is limited; best strategies are staying involved in producer associations, paying attention to policies, and focusing on sound business management.
  • “You do the things you can control ... but this is the role of belonging to organizations and making sure your voice is heard.” – C, 22:55

Notable Quotes:

• “Usually short term benefits erode the ability for us to have long term benefits. That seems to be the way life works.” – B, 19:03
• “There’s a role for veterinarians to have an opinion based on animal health. There’s a role for economists to have an opinion based on...the cattle industry. But then ... trade of cattle isn’t in a vacuum.” – C, 20:28
• “Everybody's going to be impacted or potentially could be impacted at...a different rate or even an opposite impact.” – E, 22:04

• [15:54-23:31] – Economic, health, and policy perspectives; what individual producers can do

Notable Moments & Quotes

• Memorable Analogy:

  • The hot dog toppings debate as a lighthearted introduction segued into breed diversity and “diversity within the hot dog” (03:13), drawing a parallel between food variety and breeding strategies.

• Industry Wisdom:

  • “Individual versus industry. So what's good for me may or may not be good for the entire industry.” – A, 21:27

Conclusion

This episode offers a nuanced view into management, health, and economic questions facing cattle producers. Whether it’s balancing breed diversity for optimal herd output, contextualizing animal health findings, or navigating the complicated terrain of animal trade policy, the experts bring home a central point: success in the cattle industry requires balancing biological, economic, and political factors—often with no easy answers.
