A modern approach to an old problem

Injectable trace minerals at vaccination can improve a calf’s immune response and reduce disease. This can help prevent BRD, increase antibodies and help in a calf’s immune development.
March 9, 2026
Craig J. Louder

Over the coming weeks and months, ranches across the United States will gather their herds for the annual springtime tradition of branding. In addition to marking ownership of the year’s calf crop, cowboys will administer vaccines to young calves in an effort to curb a disease that is just as consistent as the spring ritual: pneumonia or bovine respiratory disease (BRD).

Reduce transport stress for healthier calves

March 9, 2026
Craig J. Louder

Not only do we deal with stress in our lives, but we often create stressful situations for the animals we care for. Recognizing these events and taking measures to provide the animals with mechanisms to deal with stress can help them bounce back more quickly.

Acidose ou MRB : stratégies pour éviter les erreurs de diagnostic

Prendre les mesures adéquates pour prévenir l’acidose peut grandement contribuer à éviter les erreurs de diagnostic de la maladie respiratoire bovine (MRB) chez les veaux.
December 18, 2025
Craig J. Louder

Le déplacement des veaux des niches vers les enclos collectifs n’est pas seulement stressant pour les animaux. Les producteurs savent que lorsqu’un nouveau groupe de veaux arrive dans l’enclos collectif, ceux-ci courent un risque beaucoup plus élevé de contracter une maladie respiratoire bovine (MRB) ou une pneumonie.

The role of trace minerals in embryo transfer pregnancies

Trace minerals play a significant role in embryonic development, especially in embryo transfer pregnancies.
October 30, 2025
Craig J. Louder

Open. It is a word no veterinarian enjoys saying during the herd check. While researchers continue to look for ways to improve the outcomes of live births, improving the trace mineral status of the cow may be a promising way to reduce hearing that dreaded word: open.

The transition game

Just as a football coach wins by putting the right players into the game at the right time, dairy producers can help cows win by getting the right bacteria into the rumen.
September 19, 2025
Craig J. Louder

We often don’t realize that like the football team, the microbes in the rumen have their own “positions” and responsibilities. The success of the ruminant digestive system is dependent on each microbial team member performing its function.

The roller coaster of trace mineral needs

Trace mineral levels fluctuate in cows. Oral and injectable supplementation can help maintain adequate mineral status, especially during critical periods like calving and vaccination.
July 8, 2025
Craig J. Louder

For the first time in years, you felt that you could take the family on vacation this summer. It seemed like a fun idea at the time when you bought the tickets to the amusement park. Standing in line, listening to the screams and seeing the cars go flying by on the roller coaster have you second-guessing life’s decisions. Just keep reminding yourself that it will all be over in a few minutes.

Immunity: More than a vaccine

Vaccines aid cow immunity, but full immune health relies on trace minerals like zinc, copper and selenium. Proper supplementation enhances disease resistance and vaccine effectiveness.
May 27, 2025
Craig J. Louder

While vaccines contribute greatly to a cow’s immune system, there are other aspects of the immune system that should not be forgotten. Ensuring that essential elements such as trace minerals are provided, allows for the cow’s entire immune system to be ready to fight off an invasion, not just relying on the special forces.

Trace minerals boost immune function, reduce mastitis

Mastitis remains a significant challenge in the dairy industry, and while environmental factors have been addressed, improving cows’ immune systems through trace mineral supplementation, particularly via injection, may offer a promising solution for reducing the disease's impact.
March 24, 2025
Craig J. Louder

At freshening, with milk production and the risk of mastitis, the cow finds herself with the lowest levels of trace minerals to support her immune system. Even with properly balanced trace minerals going into the ration, the cow is unable to absorb them quickly enough to return her mineral stores to the levels needed to support immune function in her system and in the udder.

Acidosis or BRD: Strategies for preventing misdiagnosis

Taking proper measures to prevent acidosis can greatly aid in the misdiagnosis of bovine respiratory disease (BRD) in calves.
September 20, 2024
Craig J. Louder

Moving calves from the hutches to group pens isn’t just stressful for the calves. Workers know that when a new group of calves moves into the group pen, the calves have a much greater risk of bovine respiratory disease (BRD) or pneumonia.
