Transcriptomics, proteomics, microbiomics, metabolomics ... If you have read any scientific articles lately, chances are you have heard of one of these cutting-edge approaches. The development of technologies such as DNA microarrays, next-generation sequencing and advanced mass spectrometry have allowed for broad application in animal nutrition research.

According to Dr. Jeremy Schefers of the University of Minnesota Veterinary Diagnostic Laboratory, the rising levels of copper concentration in liver samples of dairy cattle received at the diagnostic lab remains a practical concern. The reason for the concern is the common usage of copper sulfate in footbaths on many dairy farms for the control of digital dermatitis.

In laymen’s terms, what does MUN stand for? MUN stands for milk urea nitrogen and is commonly found on every farmer’s bulk tank readings. MUNs of 5 or lower should be of concern, as the protein being fed may not be enough to meet the needs of rumen bacteria.

Investigating the underlying factors of dairy reproductive performance is a lot like peeling an onion – the more you look, the more layers you find.

When looking for ways to increase income over feed cost, the results other herds have obtained by balancing amino acids can provide insightful direction. With U.S. corn-based rations, the two amino acids that are first-limiting are methionine and lysine.

As most dairymen and dairy nutritionists know, efficient milk production is largely a matter of managing rumen function and the fermentation process.

Dietary ingredients that producers feed to dairy animals determine their efficiency and health status. In order to produce more milk, concentrates have gained popularity as an energy source for increased milk yield.

Nutrition is the foundation of a healthy and productive herd, so formulating a ration that delivers the right nutrients to meet an animal’s needs is paramount.

In 2014, the USDA reported that 89.4 percent of dairy operations in the U.S. included corn silage lactating cow diet. Dry mater intake potential and, consequently, energy content of dairy cows’ dietary consumption is limited by the amount of fiber present in the forage.

You know the routine – as soon as the tractor starts, every cow on the farm gets up and rushes the feedbunk. By the time the feed arrives, all the animals are waiting impatiently and acting like they haven’t been fed in days.
