Beef Breeding Systems and Preferences for Breeding Objective Traits.

Area of Science:

• Animal Science
• Agricultural Economics
• Genetics

Background:

• Understanding diverse beef cattle breeding systems is crucial for optimizing production and sustainability.
• Czech Republic's beef sector involves varied farm sizes, management practices, and breeding objectives.
• Characterizing these systems aids in targeted research and policy development.

Purpose of the Study:

• To identify and characterize distinct Czech beef cattle breeding systems.
• To ascertain farmers' preferences regarding breeding objectives and trait importance.
• To analyze the relationship between system characteristics and breeding goal trait preferences.

Main Methods:

• An online survey collected data from 41 Czech beef farms.
• Clustering analysis was applied using various criteria (herd size, management, marketing, breeding strategies, farmer age).
• Breeding values and performance data were jointly analyzed.

Main Results:

• Three distinct beef cattle breeding systems were identified: pure-breeding specialists (Cluster 1) and diversified production farms (Clusters 2 & 3).
• Cow temperament, calf viability, maternal fertility, longevity, and animal health were key prioritized traits.
• Functional and exterior traits dominated breeding goals (37% and 51% respectively), with production traits at 12%.

Conclusions:

• Specific farm characteristics align with distinct breeding goal trait preferences in Czech beef systems.
• Cluster 3 farms showed significantly higher production type scores than Cluster 2.
• The identified systems provide a framework for understanding and improving Czech beef cattle breeding strategies.
