CowÐCalf Producer Preferences for Bull Genomic Enhanced Expected Progeny Differences

By: Smith, Katy V. ; DeLong, Karen L.; Griffith, Andrew P.; Boyer, Christopher N.; Martinez, Charley; Jensen, Kimberley L.
Genomic enhanced expected progeny differences (GE-EPDs) combine expected progeny differences (EPDs) with DNA information to improve EPD accuracy values. In 2020, Tennessee cattle producers completed a between-subjects choice experiment for bulls marketed with either EPDs or GE-EPDs. Panel Tobit regression results indicate that, on average across all considered EPDs, producers were not willing to pay significantly more for GE-EPDs than for EPDs. However, producers were willing to pay more for the calving ease direct EPD if it was genomic enhanced. This is the first known study to evaluate producersÕ value of improved accuracy scores associated with GE-EPDs.

Bivariate MIMIC Analysis of Pasture Management and Prescribed Grazing Practices Used by Beef Cattle Producers

By: Holley, Kristen; Jensen, Kimberley L.; Lambert, Dayton M.; Clark, Christopher D.
This study applies a bivariate Multiple Indicator–Multiple Causation model to examine farm and operator characteristics associated with the likelihood of using pasture management (PM) and prescribed grazing (PGR) practices. Data are from a survey of cattle operations. Most commonly used practices included adjusting livestock and pasture fertilization. Least used were geotextiles in trafficked areas and buffering sensitive areas. Use of PM practices was income sensitive. Land stewardship and government conservation incentive views influenced PGR. Results suggest complementarities between most PGR and PM practices. However, those with higher opportunity costs and off-farm benefits (e.g., stream crossings) are not complementary with other practices.
