Talking Points

Recent interactions between the hosts and their guests.

Rethinking Statistics and P-Values in Dairy Science Publishing, Plus Dairying in New Zealand with Richard Laven, BVSc, PhD
Q: Explain why a P-value threshold like 0.05 is not a universal marker of importance.
The guest argues that P-values indicate what is unlikely if the null is true, not whether the observed effect is biologically or practically meaningful; emphasis should be on the size and practical relevance of the effect and on confidence intervals.
In Vitro Breeding, Genetics of Feed Efficiency, and Transitioning from Academia to Industry with Pablo Ross, DVM, PhD
Q: What is EcoDollars and why is it significant?
EcoDollars is a selection index weighty on feed efficiency (about 28%), designed to improve profitability by lowering feed costs while also reducing environmental impact, representing a strategic shift toward sustainability in genetic selection.
In Vitro Breeding, Genetics of Feed Efficiency, and Transitioning from Academia to Industry with Pablo Ross, DVM, PhD
Q: What prompted the move from academia to industry?
A combination of recognizing the broader impact of his work, the eye-opening experience during a ST Genetics facility visit, and the COVID-era reflection that motivated exploring opportunities beyond the university setting.
In Vitro Breeding, Genetics of Feed Efficiency, and Transitioning from Academia to Industry with Pablo Ross, DVM, PhD
Q: How did Pablo's early experiences with embryo work influence his career path?
Early exposure to embryo work sparked a lifelong fascination with developmental biology and the potential to manipulate reproductive technologies, pushing him toward a career that blends science with practical applications in livestock genetics.
Competition, Community, and the Future of Dairy’s Rising Stars with the 2025 ADSA Student Award Winners
Q: What was Mitchell's approach to his research, and what outcomes did he observe?
Mitchell outlined a controlled dietary study in mice and later cow trials, focusing on WPPC and its effects on bone density and structure, attributing improvements to protein and fat components while balancing for isocaloric conditions.
