Are you prepared for New World screwworm (NWS)? Originally eradicated from the U.S. in 1966, NWS (Cochliomyia hominivorax) larvae (myiasis) presents a challenge many cattle producers have never experienced firsthand.

Heat stress in cattle develops progressively, often beginning with subtle changes before more severe symptoms appear. By the time obvious signs such as open-mouth panting or lethargy are visible, performance losses may already be occurring.

Today’s decisions, beginning even before a calf is born, can determine whether that heifer becomes a long-lasting, productive cow or falls short of her genetic potential.

Let's get right down to it: the what and whys of rat-tail syndrome (RTS) in cattle. This trait has been around for decades, and most ranchers and cattlemen are aware of it and can easily identify those tight, curly-haired little rascals at birth.

As producers and veterinarians consider vaccination programs, it’s important to understand the key differences between autogenous and commercial vaccines.

While environmental conditions are always fluctuating, cow-calf producers often plan to experience drought. As the saying goes: It’s better to have something and not need it than to need something and not have it. Drought preparation follows the same advice.

Despite advances in vaccines, nutrition and management, bovine respiratory disease (BRD) remains one of the most persistent and costly challenges in beef production. While the weather this fall has been off to an unseasonably mild start, producers shouldn’t mistake low rates of BRD in early months for a disease-free season.

All producers aim to maintain the health of their herds. Because losses from sickness and death take a toll on cattle and producers alike, it can be helpful to periodically review farm biosecurity practices.

Bovine respiratory disease (BRD) is essentially pneumonia. Caused by specific bacteria and viruses, it is the most expensive disease in the beef industry.
