A Dairy Misconception: Malnourished Cows

Finding these cows similarities, could be difficult but finding the differences are very easy. As for similarities: they are both female cattle (cows) that have calved semi recently. It is obvious in the picture in the right of the Hereford because she has a calf beside her, in the picture of the Jersey (on the left) there is no calf but you can tell that she has calved somewhat recently because of her large udder.

As for the differences, their builds contrast one another. The Jersey on the left looks skinny, as her hip bones and ribs are showing. The Hereford is very stoutly built, she has adequate rib shape and depth. The Hereford is nursing a calf at her side, but produces less milk than the Jersey. Lactation in any animal, including humans, is the single most energy demanding activity.  Hereford cattle produce about 10-12 pounds of milk a day, while Jersey cattle produce around 50 pounds a day, which takes 10x more of the cows energy. The more energy spent to produce milk is less energy that will be used to produce meat. This does not mean that the Jersey is malnourished!! As a dairy cow she just has a different body type than beef cattle. This difference in body type is because of each cows purpose.

A dairy cow being skinny is not her being malnourished, it is actually called dairy characteristics. Dairy cattle are supposed to produce milk, so they expend a lot of energy doing just that. “Producing milk and growing body tissue are different physiological processes, under different controls” says Dr. Keith Cummins a retired dairy professor from Auburn University.

I hope the next time you see a a dairy cow, either in person or in a picture you will better understand why she looks “malnourished” and understand that she is not, she is actually a perfectly healthy cow that is working very hard to produce milk for you and your family.
