Don’t let winter’s cold open the door to BRD
Good animal husbandry is a crucial component of cold stress management, says Nathan Meyer, DVM, PhD. When cattle are putting a lot of energy toward staying warm, they become more susceptible to disease challenges so managing their environment is important to reduce disease risk. Meyer asserts the importance of quality water and matching nutrition to help keep cattle … [Read more...]

Managing water efficiently, sharing how it’s done is increasingly important to consumers
Water is central to dairy’s future, but how dairies use and conserve it is no longer just an operational concern; it’s a story the public is watching. There are several ways dairies can reuse water throughout their operations, and many farms already rely on these practices to stretch every gallon. Improving sustainability begins with understanding exactly how much water a dairy … [Read more...]

Fewer cull cows are driving dairy herd growth
The milk cow population has been trending upward since December 2024, largely due to dairy cow retention, writes Abbi Prins. Instead of cull cows showing up in cattle slaughter reports, these cows are still being milked in barns across the country and are making calves destined for beef feedlots.

Variable hay quality a concern during cold snaps
Cattle feed intake can surge higher than 20 percent to make up for energy expended to keep them warm. Amber Friedrichsen reminds us that a large spread in hay quality across the Midwest exists, making it that much more important to test forage and budget for additional bales or supplemental feed. In short, a bale ≠ a bale ≠ a bale. Source: Hay and Forage Grower, December … [Read more...]
Better water, better pig health
Water quality and water delivery systems remain a critical component of optimizing animal health, regardless of the species.

Reimagining animal handling training: ‘Mooving Cows’
One of the most significant welfare determinants on dairy farms lies outside the treatment pen: how cows are moved and handled. Cow-handling practices directly affect stress physiology, lameness risk, udder health, milk let-down and handler safety. Yet, the churn of dairy employees and getting good training limits consistent improvements. Seeing an opportunity to improve … [Read more...]
Shedding placental membranes, uterine restoration postpartum in dairy cows
Transition cow management and care is important in dairy production. Each phase requires attention at the individual cow level.

Source: Progressive Dairy, … [Read more...]
Study reveals T cells drive PRRSV vaccine protection
Porcine reproductive and respiratory syndrome virus is one of the fastest-mutating RNA viruses that veterinarians face. Although current vaccines offer protection, the rapid mutation of PRRSV means that vaccinated pigs cannot produce a consistent or effective broadly neutralizing antibody response. Current vaccines are successful in helping the body identify and attack pieces … [Read more...]
Airborne H5N1 may be a factor in outbreaks
If bird flu is airborne, the government’s current biosecurity-based strategy cannot protect farms on its own, writes Nat Lash, an investigative journalist.
