Even mild cases can impact milk production, health and well-being. Researchers, citing expenses and losses farmers incur from the problem, say costs per case commonly range from $76, on the low end, to more than $336, on average.
Soon after the discovery of highly pathogenic avian influenza (HPAI) strain H5N1 in dairy cattle, scientists learned that milk was a primary vector in spreading the disease from cow to cow.
One of the easiest and most effective biosecurity practices to adopt is having separate footwear and clothing for wearing on and off the farm or ranch. Check out the other five ideas our industry experts recommend.
The report echoes calls by other scientists to ramp up the surveillance of felines, which are susceptible to the virus and have a high mortality rate. The AVMA says several cases in cats linked to poultry or wild bird exposure had been reported before the outbreak began in dairy cows last spring.
A decade into the partnership, GenoSource has grown into more than the original partners ever imagined. The dairy now involves eight families, who all love Holsteins and share a goal of creating a more sustainable future for the next generation.
The pest can travel on humans, vehicles, pets, livestock and even on some wildlife species — all of which increase the likelihood it could eventually enter our country.
Any existing herd health problems are amplified by HPAI H5N1, practitioners report. Some are asking regulatory agencies for more consistent testing and reporting protocols. They are also encouraging producers to invest dollars in better nutrition and cow comfort resources.
NCBA Policy director urges cattle producers to be diligent and watch for New World screwworm flies.
The program is open to association members who graduated between 2017-24. The event is set for Feb. 14-15 in Norman, Okla.
The Nov. 22 closing of the southern border to cattle imports from Mexico due to detection of New World Screwworm in a cow brings up questions regarding the history and future of trade with the country.
U.S. and Mexican officials are working together on pre-export inspection protocols before resuming live cattle imports into the U.S. The use of sterile flies is also a priority to help control the spread of NWS in Mexico.
In a USDA study, 7.9% of U. S. cow-calf operations were found to contain one or more Johne’s positive cows.
There are warning signs that can help you determine whether it’s needed. Here are six to consider.
Activity and rumination monitoring systems -- precision cow monitoring -- can revolutionize the way a dairy manages its cows. Or they can pile up frustrations and create greater expense without adding value.
The project, developed by Cooperative Extension livestock specialists and veterinarians, aims to mitigate profit, production and financial risks to cattle producers.
A partial answer to addressing the work ruts that recent graduates can get into is a counterintuitive measure. We sometimes need to pull them off the front line.
The study also showed that a bovine H5N1 virus is susceptible to the antiviral drugs favipiravir and baloxavir marboxil (brand name Xofluza) of the polymerase inhibitor class, as well as the neuraminidase inhibitor zanamivir.
Pain is a natural condition for all animals and humans. But when it comes to dairy cattle specifically, the intensity and duration of their pain can have significant influence on both their welfare and productivity.
Three producers open up and share about their journey of innovation and technology as a way to spell longevity to their dairy operations.
David Lalman, Ph.D., has researched cow size and feed efficiency with intent to help producers create a cowherd that is resilient and productive in the best environment and still productive in the worst of years.
The essential oil from oregano is proving beneficial for calf diets. Two studies have shown it to have positive impacts on calf health and performance as an alternative to antibiotics.
At the end of the day, your cowherd’s body condition score is an insurance policy or risk management. Now’s the time to increase that score to prepare your herd for winter weather.
More than 50 animals, to date, including cattle and one moose have died. Officials say the current risk to humans is small.
At least four additional states have confirmed cases of rabies in cattle this year.
Researchers say whole genome sequencing of the virus did not “reveal any mutations in the virus that would lead to enhanced transmissibility of H5N1 in humans, although the data clearly shows mammal-to-mammal transmission.”
Check out these practical ideas and recommendations offered by the four hard-working, dynamic bovine practitioners who made up the program committee for the 2024 AABP Recent Graduate Conference.
USDA’s Animal and Plant Health Inspection Service (APHIS) updated requirements for dairy cattle as follows:
Steve Troxle, state commissioner of agriculture, said he is waiting for more diagnostic information from the National Veterinary Services Laboratory and will work collaboratively with North Carolina dairy farmers.
The American Association of Bovine Practitioners is making the name change, as it more accurately reflects the issue.
The past few winters have thrown many curve balls at cattle producers. In addition to causing stress, these conditions are tough on cattle’s overall health, making deworming this spring even more important.
