This article, from researchers from the University of Wisconsin, discusses a study that aimed to examine the genetics of milk yield consistency within and between lactations of U.S. Holstein cows.

Failure to detect and intervene in feed composition changes during the production and delivery of dairy cattle diets increases the uncertainty of the nutrients actually delivered which, in turn, increases the risk of underfeeding or overfeeding cows. 

Dairy cull cow marketing trailed year-ago levels for 14 consecutive weeks.

A good milk letdown is what leads to faster milking speeds, not the other way around. So, how can you lead your herd into a good letdown to see top speeds and improved milk production?

Milk synthesis exhibits a daily rhythm that is modified by the timing of feed intake. However, it is unknown how specific nutrients entrain this daily rhythm.

Persistency is usually considered a genetic trait. However, a new study shows that nutrition may play a larger role than originally thought.
