Is Your Hay Supplying Enough Vitamin A This Winter?

Vitamin A plays a critical role in young calf health. Calves are born with very limited vitamin A stores because little transfers from the dam during gestation. Newly born calves rely heavily on colostrum for their supply of vitamin A, making the cow’s late-gestation diet critically important. Milk is a poor source, so calves depend on the colostrum for their Vitamin A supply for the first few months of life.

For most herds calving in late winter or spring, cows are fed stored or stockpiled forages during their last trimester.

How Can We Grow More Food With Less Impact?

Video: How Can We Grow More Food With Less Impact?

For over two decades, Dr. Mitloehner has been at the forefront of research on how animal agriculture affects our air and our climate. With deep expertise in emissions and volatile organic compounds, his work initially focused on air quality in regions like California’s Central Valley—home to both the nation’s richest agricultural output and some of its poorest air quality.

In recent years, methane has taken center stage in climate discourse—not just scientifically, but politically. Once a topic reserved for technical discussions about manure management and feed efficiency, it has become a flashpoint in debates over sustainability, regulation, and even the legitimacy of livestock farming itself.
