Enhancing Your Herd with Genetic Selection with Matt Spangler

DocTalk

Hey folks, welcome to another insightful episode of "DocTalk!" Today, we're joined by Dr. Matt Spangler from the University of Nebraska, a renowned expert in animal genetics. We’re diving deep into genetics, bull selection, and strategies to boost your herd's profitability.

Key Points:

1. Year-Round Bull Selection:
- Bull selection is a continuous process, not just a last-minute decision. Assess your ranch's
needs and profit drivers well before the bull sale season.
- Determine your breeding objectives: Do you retain replacement heifers or sell all calves at
weaning? These decisions impact the traits you should prioritize.

2. Identifying and Utilizing Economically Relevant Traits:
- Understand your herd's performance metrics like calf weight and pregnancy rates to identify
areas for improvement.
- Ensure your breeding system is optimized, leveraging heterosis by using appropriate breeds for
crossbreeding.

3. Importance of Heterosis:
- Crossbreeding with more divergent breeds maximizes heterosis, leading to better overall herd
performance.
- While using different sire lines within a breed offers some benefits, crossbreeding different
breeds yields more significant genetic advantages.

4. Marketing Calves with Better Genetics:
- Providing information on the genetic potential of your calves can increase their market value.
Feedlots are willing to pay more for calves with known performance traits.
- Programs and certifications highlighting superior genetics are becoming more common,
offering potential premium prices for your cattle.

5. Managing Cow Size and Lactation:
- Larger cows and high milk producers can increase input costs. Moderating cow size can reduce
maintenance costs and improve fertility rates.
- Smaller cows can still produce large, marketable calves, optimizing land use and profitability.

6. New Tool: iGENDEC:
- iGENDEC is a web-based tool to help beef producers select bulls based on their unique profit
potential.
- By inputting specific herd data, the tool generates a customized selection index, guiding you to
make the best genetic choices for your operation.

Conclusion:
Understanding and applying genetic principles can significantly enhance your herd's performance and profitability. Thanks for tuning into "DocTalk" with Dr. Dan Thompson and Dr. Matt Spangler.
