Midwestern beef production works just as well off pasture

Research shows that cow-calf pairs can be managed in drylots throughout the summer grazing period without significant negative effects on growth performance, lactation, and reproductive rates. Calves raised in drylots had increased performance compared to pasture-raised calves, but still showed signs of stress during weaning.

When job seekers are “overqualified,” gender bias may come into play

A new UC San Diego study reveals that overqualified women are more likely to be hired for jobs and ranks compared to sufficiently qualified men. Hiring managers assume overqualified women leave due to gender discrimination, rather than flight risk. This suggests firms may not be utilizing their expertise and experience effectively.
