The $10 Tool Randy Dowdy Uses To Grow Record Corn Yields

Mon, 06 Apr 2026 19:08:35 GMT

For high-yield corn grower Randy Dowdy, a successful harvest doesn’t start with the combine; it starts with a ratchet strap and an open furrow.

While many growers rely on high-tech in-cab monitors to guide their planting process, Dowdy argues the most critical data they need is found in the dirt behind the planter. By using ratchet straps to hold closing wheels up and out of the soil, he creates an “open furrow” that allows for a level of diagnostic evaluation he believes covered seeds cannot provide.

The Depth Deception

The logic behind this unconventional start to corn planting is rooted in the physical reality of soil settling. Dowdy, based near Valdosta, Ga., notes that even when a grower sets the planter for a standard two-inch depth, the final result often differs from what they were trying to achieve.

“Whenever the farmer goes back and looks at the plant, once it’s emerged, they find the germination depth is not the same depth as they planted,” he says. “Why did they not look at it and set it appropriately in the beginning? Chances are they can read that popsicle stick and measure depth. They know how to do that. But one thing I’ve found is that ground, when it’s been worked... it just settles.”

Whether a field is under conventional tillage, strip-till or no-till, the act of moving soil creates a “fluff” factor that can deceive even experienced corn growers. To compensate for this tendency, Dowdy advocates for planting slightly deeper in tilled or loose ground so the seed remains at the desired depth after the soil settles.

Open Furrow Diagnostics

To verify seed placement depth, Dowdy likes to use an open furrow for evaluation. He says this method allows growers to see exactly how the row unit is interacting with the soil environment without guesswork.

“I don’t like to stand on top of my head and scratch for seed and all that garbage,” Dowdy says. “The first thing I want to do is make sure the row cleaners are set properly. I can do that better with an open furrow. I can look at spacing that way. I’m not standing on top of my head scratching, spending all this time trying to find it.”

The open furrow provides a clear window into the planter’s performance. Beyond spacing and row cleaner settings, it allows the grower to inspect for sidewall smearing—a problem that can severely limit root development if the soil is too tacky when the opening discs pass through. The visual check of an open furrow also tells the grower whether the down pressure is sufficient to maintain a consistent planting depth.

The Centering Challenge

Once the open furrow confirms that the row cleaners, meters, and depth settings are dialed in, the focus shifts to the closing system. Dowdy warns that even the best closing wheels can fail if they aren’t perfectly aligned over the seed.

He says standard V-press wheels are known to drift off-center. If they aren’t tracking directly over the seed trench, they don’t just fail to close the furrow—they actively change the planting depth at the final stage of the process.

“It doesn’t matter whose system it is, V-press wheels just do not like to stay centered,” he contends.

When the wheels drift off-center, they often pinch the furrow, leaving a raised ribbon of soil in their wake. This misalignment can create a less than desirable environment for the seed than what the grower intended.

A Systematic Start

Dowdy’s systematic approach—checking gauge wheels, setting opening discs, inspecting the open furrow, and finally calibrating the closing wheels—is designed to eliminate the variables that lead to uneven emergence. For Dowdy, the goal is to ensure that every seed is given the exact same opportunity to start strong, leading to the “picket fence” stands required for high yields.

By starting with an open furrow and systematically lowering the closing system only after everything else is verified, he says other corn growers can eliminate the guesswork that often leads to costly mistakes at planting.

“We’re not done, but this is the process of how we get started,” Dowdy says. “Next, we’ll let the closing wheels down, close that trench and see what we got.”

Be Aware: Dangerous Asian Longhorned Tick Continues Migrating West

Wed, 18 Jun 2025 14:42:46 GMT

The Asian Longhorned Tick (ALHT) poses a serious threat to cattle health. ALHTs carry Theileria, which is a protozoan parasite that infects red and white blood cells. It can lead to anemia and, in some cases, death.

ALHTs are native to eastern Asia, eastern China, Japan, the Russian Far East and Korea but were introduced to Australia, New Zealand and western Pacific Islands. In other countries, it can also be called a bush tick, cattle tick or scrub tick.

In the U.S., ALHT was first detected in New Jersey in 2017. Since then, it has spread to more than 20 states with recent confirmations in Illinois , Michigan and Iowa .

According to USDA’s Animal and Plant Health Inspection Service (APHIS) ALHTs are known to carry pathogens, which can cause disease and may also cause distress to the host from their feeding in large numbers. For example, a dairy cow may have a 25% decrease in milk production after becoming a host.

A female can reproduce without a mate and lay up to 2,000 eggs at a time. This can cause great stress on a heavily infested animal and result in reduced growth and production. A severe infestation can kill the animal from excessive blood loss.

What does it look like?

Unfed ALHTs range from a light reddish-tan to a dark red with brown, dark markings. While the adult female grows to the size of a pea when full of blood, other stages of the tick are very small — about the size of a sesame seed.

Adult females are a grey-green with yellowish markings. Male ticks are rare.

APHIS reports it only takes a single tick to create a population in a new location.

ALHTs need warm-blooded hosts to feed and survive. They have been found on various species of domestic animals — such as sheep, goats, dogs, cats, horses, cattle and chickens — and wildlife. The tick has also been found on people.

What are the health risks?

APHIS says ALHTs are not known to carry Lyme disease, but they can cause tickborne diseases affecting humans and animals such as:

Rocky Mountain spotted fever
Heartland virus
Powassan virus

APHIS says those diseases have not been confirmed outside of a laboratory setting in the U.S. In addition, U.S. ALHT populations can transmit U.S. Theileria orientalis Ikeda strain (Cattle theileriosis) in the laboratory.

In an Iowa State University release , Grant Dewell, Extension beef veterinarian and associate professor, says cattle affected by Theileriosis will show signs of lethargy, anemia and difficulty breathing. They may develop ventral edema, exercise intolerance, jaundice and abortions.

“Although signs of Theileriosis are similar to anaplasmosis, younger animals and calves often display more severe signs compared to mature cows and bulls,” he says. “Due to anemia from both tick infestation and Theileria, the risk of death can be elevated. If cattle producers suspect either Theileria or ALHT, have a veterinarian collect appropriate samples and submit them to a veterinary diagnostic lab.”

According to an Oklahoma State University press release , under laboratory conditions ALHT is a competent vector of numerous pathogens that can cause disease in humans, including Rickettsia rickettsii (Rocky Mountain Spotted Fever), Heartland Virus and Powassan Virus.

In “ Clinical Infectious Diseases, ” Bobbi Pritt, MD, MSC, with the division of clinical microbiology at the Mayo Clinic in Rochester, Minn., reported a human bite that occurred in New York in 2019. She says though the report of a human bite isn’t surprising, it proves the invasive longhorned tick continues to bite hosts in its newest location.

“This is extremely worrisome for several reasons,” she writes. “One reason is Asian longhorned ticks can carry several important human pathogens, including the potentially fatal severe fever with thrombocytopenia syndrome (SFTS) virus and Rickettsia japonica, which cases Japanese spotted fever. While these pathogens have yet to be found in the United States, there is a risk of their future introduction.”

Also, Pritt says several other human pathogens have been detected in the ticks, but it’s not clear if the ALHT species are able to transmit them to humans. They include Anaplasma, Ehrlichia, Rickettsia, and Borrelia species. Lyme disease is caused by Borrelia burgdorferi bacteria.

She warns the organisms are present in states where ALHTs have been found and that it’s possible the tick — known to be an aggressive biter— might be able to transmit Heartland virus given its close relationship to SFTS virus.

How to Tackle Ticks

According to APHIS, various strategies effectively mitigate tick populations on hosts and in the environment.

Regular tick treatments should be effective against ALHTs. Consult your veterinarian or agriculture extension agent about which products to use.
Check your livestock for ticks regularly.
Safely remove ticks from people and pets as quickly as possible. If you think you’ve found an ALHT, seal it in a zip-top bag and give it to your veterinarian for identification.
Habitat modifications can help prevent ticks on feedlots and pastures. This may include mowing grass, removing trees, reducing shade by thinning trees, understory removal and placing mulch barriers.
Apply acaricide using label instructions to tick habitats, such as woodland edges and grassy patches, during times when ticks are most actively seeking hosts. Although it varies by year, ALHTs are generally active from March to November. Consult your state and local regulations for approved acaricides.

“Cattle producers should aggressively control external parasites this summer,” Dewell summarizes. “Insecticide ear tags alone are not enough to control ticks. Consider incorporating a back rubber or regularly applying a pour-on during the summer. Pyrethroid-based products are also available that include a tick control label. If an increase in tick infestations is observed, an avermectin pour-on may be the best intervention.”

New Study Says Domestic Cats Need To Be Evaluated More For HPAI H5N1 Implications

Mon, 13 Jan 2025 20:04:17 GMT

Dairy cattle have garnered most of the agriculture industry’s attention in the past year, with regard to outbreaks of the highly pathogenic avian influenza A (HPAI) H5N1.

Now, some researchers are turning their attention to other animals on the farm impacted by the virus: cats.

A new study published Monday in the journal Emerging Microbes & Infection addresses how domestic cats are affected by the virus and notes concerns such felines could offer the potential for HPAI H5N1 to evolve into a more dangerous version of the virus.

The study – which addresses the deaths of 10 cats in rural South Dakota last April – is not the first time researchers have raised concerns about the virus in cats and the potential for transmission to other mammals.

‘Urgent Need For Surveillance’
Researchers at the University of Maryland School of Public Health said in June 2024 that a “20-year review of bird flu in felines suggests urgent need for domestic cat surveillance.”

Kristen Coleman, an assistant professor in the UMD School of Public Health, and an affiliate professor in the University of Maryland Department of Veterinary Medicine, said, “As companion animals, domestic cats provide a potential pathway for avian influenza viruses to spillover into humans.” (Researcher Warns Pet Cats Risk Getting Bird Flu)

“We looked at the global distribution and spread of bird flu infections in feline species between 2004 and 2024 and found a drastic rise in reports of feline infections starting in 2023, with a spike in infections reported among domestic cats, as opposed to wild or zoo-kept animals,” added Coleman, who was not involved in the South Dakota study.

There is no study that shows transmission occurs from HPAI H5N1-infected cats to humans. Furthermore, current research shows HPAI H5N1 does not readily spread among humans, though studies have noted one or two key mutations could change that fact.

The virus often does take a deadly toll on felines. According to the University of Maryland’s School of Public Health , infected domestic cats have a mortality rate of up to 67%.

Last week, the Cornell University College of Veterinary Medicine Animal Health Diagnostic Center published directions online for veterinarians testing cats for highly pathogenic avian influenza (HPAI) .

AVMA Weighs In
“Dozens of cats are known to have contracted the virus, including barn and feral cats, indoor cats, and big cats in zoos and in the wild (e.g., mountain lions, tigers, leopards, and bobcats),” according to the American Veterinary Medical Association (AVMA). “Cats were already known to be susceptible to the H5N1 virus, with several feline cases linked to poultry or wild bird exposure before the cattle outbreak began,” AVMA said.

See Avian influenza A (H5N1) in cats for the Association’s recommended practices for dealing with any suspected of being infected by the virus.

‘A Possible Link’ To Local Cattle
The study published on Monday said virus-infected birds could have played a role in the South Dakota felines’ demise.

In addition, the report said: “The exact source of infection remains unclear; however, phylogenetic analysis of H5N1 sequences from two of the cats reveals a close genetic relationship to clade 2.3.4.4b strains previously detected in local cattle, suggesting a possible link.

“Additionally, the presence of bird feathers near the deceased cats indicates the likelihood that infection may have occurred through the consumption of virus-infected birds. However, because the disease typically requires several days to manifest post-ingestion, the exact timing of exposure is unclear. This evidence points toward a plausible cattle-to-bird-to-cat transmission pathway, supported by recent studies that identified H5N1 sequences across multiple species on affected farms, including dairy cows, wild birds, domestic cats, and raccoons.”

Many Mammal Species Impacted
According to USDA-APHIS, more than 200 mammal species in the U.S. have been infected by the virus since 2022.

Along with cows and cats, other U.S. mammals infected with the virus include a bottlenose dolphin, foxes, bobcats, mountain lions, coyotes, skunks, harbor and grey seals, opossums, squirrels, minks, otters, black bears, brown bears, polar bears, and a single pig on a backyard farm in Oregon, confirmed in late October.

The CDC encourages veterinarians and other individuals working with cats or other mammals that are suspected or confirmed positive for HPAI H5N1 to take precautions to prevent potential unprotected exposures.

GenoSource Has Grown Into One of the Most State-of-the-Art Dairies You'll Find in the U.S.

Mon, 06 Jan 2025 22:11:18 GMT

The Milk Business Leader in Technology Award is given to a farm that focuses on the implementation of technology to improve dairy operations in terms of ROI, labor, time management, etc. GenoSource was named the 2024 Milk Business Leader in Technology Award Winner during the 2024 MILK Business Conference in December.
_______________________________________________________________

At first glance, these two might just look like typical business partners, but peel back the layers, and it’s clear Tim Rauen and Kyle Demmer are more than just that.

“We’re coworkers, we’re partners and we’re best friends,” says Kyle Demmer, COO of GenoSource. “Pretty much everything we do, we kind of bounce ideas off each other and just feed off each other.”

Tim Rauen, CEO of GenoSource, and Kyle Demmer, COO of GenoSource, give a tour of their facilities where they milk 4,000 cows milk in a 90-stall rotary parlor. Their cows are milked 3x/day and average 90 lbs/day with a 4.5% Butterfat and a 3.5% Protein.

It’s a partnership in every sense, but the dairy is also anything but typical.

GenoSource all started with a dream a decade ago; a dream to have a company created by dairy producers for dairy producers. The vision seemed simple but was complex in reality. The dairy farmers wanted to create a modern cow but one that excelled in a freestall environment, had fewer health issues and could convert feed at an efficient rate.

“And now we’re 10 years into this partnership and GenoSource, and I don’t think anyone would change a thing about it,” says Tim Rauen, CEO of GenoSource.

The partnership now involves 8 families, whom all have a love for Holsteins and share a goal of creating a more sustainable future for the next generation.

(GenoSource)

An Early Believer in Genomics
A decade into the partnership, GenoSource has grown into more than these families ever imagined. The partnership now involves eight families, who all love Holsteins and share a goal of creating a more sustainable future for the next generation.

“Being an early believer in genomics, I followed technology, graduated college in 2008, and I told myself we got to follow technology; we’ve got to lead technology for the industry, and we drove right into it,” Rauen says. “We had a lot of naysayers that said, ‘Hey, this isn’t going to work. You shouldn’t go this direction,’ but we did. We put our foot on the gas, and we put the hammer down with it.”

To achieve the highest possible results, GenoSource prides their operation on the integrity of their day-to-day work, their capability to fill the next industry-leading demand and the philosophy of breeding a more profitable cow by investing in some of the world’s greatest genetics. GenoSource believes that genetic advancement is what will help develop the ideal cow for the future.

(Russ Hnatusko )

By homing in on the genetics early on with genomic testing, it’s their ability to grasp onto a plethora of technologies that’s taken this dairy to the next level.

“From a genetics standpoint, we took the herd that we bought, we put embryos into them and ran an extensive embryo program from day one to roll the herd over to the kind of cows we believed in milking,” Rauen says. “We were milking 2,200 cows at the time, and when we came in to it, we were milking about 70 lb. per cow with a 3.4% butterfat and a 2.8% protein. So since then, we’re at 95 lb. per cow. We’re at a 4.6% fat in a 3.5% protein.”

A Growth Mindset
GenoSource expects to be milking 4,800 cows by next summer, as GenoSource excels at improving genetics, cow comfort, nutrition and management, all through technology.

“On the genetics side of things, I look at genomic testing, I look at IVF work,” Rauen says. “Then, I go into cow comfort. We utilize the tunnel ventilation side of things. I go into the parlor. There’s many tools inside the parlor that the technology has advanced over the years. And then on the management side, there’s many things from the database side of things and monitoring tools that are cow monitoring collars. There’s multiple levels of that. So, all four of those have many, many layers of technology, and I don’t think you can ignore any of those. And you just got to look at all of them and see how you can improve the herd.”

Barns Packed With Technology
Their barns are also packed with technology. The dairy installed tunnel ventilation and smart control in 2021, as the dairy was forced to rebuild after the devastating derecho tore through their farm in august of 2020.

“Prior to the derecho, we were looking at putting tunnel ventilation in,” Rauen says. “We were looking at adding another barn to the facility as we want to grow and melt more cows. And it was that time where when we had to do that remodel, it pretty much forced our hand and said, ‘Hey, let’s go get tunnel ventilation done to our barns.’”

The team decided to expand the barns to add additional rows, which Rauen says was a big change. And while it was frightening financially to make that decision, he’s glad they did.

New construction across GenoSource are signs of more progress underway today, with GenoSource in the middle of putting in a new methane digester, a new maternity barn and a dry cow calving facility.

(Mike Byers )

New Construction: Signs of More Progress Underway
Today, new construction at their dairy is a sign of more progress underway, with GenoSource in the middle of building a methane digester, as well as a new maternity barn.

“We’re also building a new dry cow calving facility. We feel it’s so important when these cows come out day one that everything’s done properly from the cleanliness to colostrum. And also taking care of that cow, so she’s ready to make milk for a full lactation,” Rauen says. “The barn is going to be fully ventilated and have a sprinkler system. There’s a lot of new ideas we’re putting into those facilities, because we’re always looking for ways to increase the cow comfort side of things.

With technology at their fingertips, GenoSource is constantly monitoring their operations.

(Russ Hnatusko )

Work Smarter, Not Harder
The progress hasn’t always been easy, but just look around GenoSource’s state-of-the-art facility, and you can see those investments are paying off.

“Sometimes you need to work smarter, not harder,” Demmer says. “We have the smart sort gate, we have the collars; it makes a lot of people’s jobs a lot easier, and you can be way better at your job.”

With tech like Farmfit, which helps them constantly monitor their animals, it’s that technology that helps the dairy produce a better a better environment for the cows, and it also helps them retain employees.

“Three years ago, we used to lock every all the cows up and give repro shots, vaccines, breed everything out here in the barns,” Demmer says. “Now, we never lock the cows up. We put them in the sort gate and let the cows come to us. As far as injuries and employee safety, it’s all huge. You don’t have to worry about chasing the cows around. I think there’s a huge cost savings, too, and it’s way safer for the cows and the people.”

Cow Comfort is Key
GenoSource has created an environment where these cows are content, which might be the biggest sign of success any dairy can have.

“Some things that excite me the most are the cows are happy,” Rauen says. “So, when you have happy cows, they help pay the bills, and you can come out here 365 days a year, and cows are out here making milk. I always have the motto, ‘you take care of the cows, they’ll take care of you.’”

A dairy that knows no limits, it’s embracing technology that’s allowing GenoSource create new opportunities on their farm.

“Honestly, technology helps you get through some of those challenges, and we’re able to pull the data from different things,” Rauen says. “I think we’re ready for the next 10 years.

That is why GenoSource is the 2024 Milk Business Leader in Technology Award winner.

North Carolina Reports First Case of HPAI in Dairy Herd

Wed, 10 Apr 2024 19:59:16 GMT

The National Veterinary Services Laboratory (NVSL) has detected Highly Pathogenic Avian Influenza (HPAI) in a dairy herd in North Carolina.

The North Carolina Commissioner of Agriculture, Steve Troxle, said in a press release he is waiting for more diagnostic information from the NVSL and will work collaboratively with federal partners and dairy farmers in the state.

“We have spent years developing methods to handle HPAI in poultry, but this is new and we are working with our state and federal partners to develop protocols to handle this situation,” he said. “It is important to note the FDA has no concern about the safety or availability of pasteurized milk products nationwide.”

North Carolina is the seventh state to officially confirm the presence of HPAI in a dairy herd.

The other six states with NVSL-confirmed reports of HPAI in dairy are:

Idaho: 1 case
Kansas: 3 cases
Michigan: 2 cases
New Mexico: 4 cases
Ohio: 1 case
Texas: 9 cases

In addition, the National Milk Producers Federation reports that eight states now have dairy cattle importation requirements or restrictions:

The Federation adds that there is “no concern about the safety of the milk supply or that this circumstance poses a risk to consumer health because products are pasteurized before entering the market, per the Food and Drug Administration (FDA). Only milk from heathy animals is authorized for distribution into interstate commerce for human consumption. Additionally, pasteurization has continually proven to inactivate bacteria and viruses, including influenza, in milk.”

Six Questions One Industry Veterinarian Says She Is Asked Most Often About HPAI

AABP Decides to Reference Cattle Disease as Bovine Influenza A Virus (BIAV)

Tue, 09 Apr 2024 20:17:20 GMT

On Sunday evening, the American Association of Bovine Practitioners (AABP), released a letter to its media partners to update them on how the organization will reference the emerging cattle disease, currently confirmed in dairy herds in six states, moving forward.

“Because this infection in cattle is not the same as highly pathogenic avian influenza (HPAI), after thoughtful consideration and discussion with many experts, the AABP will now refer to this as Bovine Influenza A Virus (BIAV), which more accurately depicts it,” wrote Geni Wren, director of marketing and communications for the organization, in an email accompanying the letter.

The letter was developed and signed by AABP executive director, Fred Gingrich, DVM, and president Michael Capel, DVM.

Gingrich and Capel are asking other organizations, state animal health officials, diagnostic labs, and state and federal agencies to use Bovine Influenza A Virus (BIAV) “so we can be consistent with our messaging and better distinguish the disease syndrome in cattle from the pathogenesis in birds. We believe it is important for the public to understand the difference to maintain confidence in the safety and accessibility of beef and dairy products for consumers,” they wrote.

The letter is available in its entirety for review here:

Twelve Cases of HPAI in Dairy Cattle Confirmed in Five States

Wed, 03 Apr 2024 18:54:11 GMT

To date, 12 cases of highly pathogenic avian influenza (HPAI) have been confirmed in dairy cattle in five states.

The U.S. Department of Agriculture has made the confirmations in dairy herds in four states: Texas (7), Kansas (2), Michigan (1), and New Mexico (1).

In addition, the Idaho State Department of Agriculture announced March 28 that it had identified its first cases of HPAI in a Cassia County dairy cattle operation. The affected facility had recently imported cattle from another state and herd that had HPAI.

Fred Gingrich, DVM and executive director for the American Association of Bovine Practitioners (AABP), says the virus identified in affected dairy cows is the same virus that has affected the U.S. poultry industry since 2022.

“The assumption is the initial herds were affected by wild migratory birds,” Gingrich told Chip Flory, host of AgriTalk, on Tuesday.

Gingrich adds that government agencies, veterinarians and livestock industry groups have more questions than answers at this point about how HPAI is infecting herds, and they are not ruling out cow-to-cow transmission.

“Clinically, it looks like that’s what is happening. Some of the newly infected herds outside of Texas had purchased animals from areas there that had affected herds. That indicates that we probably have some cow-to cow transmission,” Gingrich says. “What’s not known is how does that transmission occur? Does it occur through oral secretions, through the manure, urine, or aerosolized in respiratory secretions like it is in birds? Or is there some mechanical transfer when cows are in the parlor together?”

Adopt Good Biosecurity Practices
The many unknowns at this point make the need for producers to adopt good biosecurity measures more important than ever. Gingrich says the AABP and the National Milk Producers Federation have teamed up to release a set of biosecurity guidelines for producer and veterinarian use. The guidelines and recommendations are available at bit.ly/3TGYMul.

The key points in the guidelines, Gingrich says, encourage dairy producers to minimize any opportunity for the transmission of HPAI by: minimizing livestock contact with wild, migratory birds, isolating new animals on the farm, limiting any visits to your farm to only essential workers and practicing good, general biosecurity measures.

“If you’re moving either your own cattle home from a heifer grower, or you’re purchasing animals, talk to your veterinarian about any potential screening that you might want to do for those cattle, which is just a good practice for any potential disease,” Gingrich advises. “Certainly, you just need to be careful about herd purchases when we have unknowns with an emerging viral event.”

Producers should use the same general precautions, Gingrich adds, for beef cattle and other livestock as well.

“Currently, there are no reports of HPAI in the U.S. beef herd, but certainly producers and veterinarians should be on alert to monitor and watch for any symptoms,” he says.

Five states, Delaware, Idaho, Nebraska, Tennessee and Utah, are taking additional precautions to increase their biosecurity measures. Dairy Herd Management’s Taylor Leach reports the Nebraska Department of Agriculture (NDA) has issued a restriction on the importation of dairy cattle because of the recent HPAI outbreaks.

Silver Linings In The Clouds
When dairy cows are affected by HPAI, they tend to be only a small percentage of the total herd.

“It only affects about 10% of the cows in a herd, and it does not cause mortality, and we’re thankful for that,” Gingrich says.

Furthermore, any risk to the U.S. public from consuming dairy and meat is very low, because pasteurization destroys the virus.

Looking Ahead
Moving forward in the days and weeks ahead, Gingrich recommends that producers work closely with their herd veterinarians and sign up for HPAI alerts as they are released by the Centers for Disease Control, USDA and other federal and state agencies.

“I think the first thing is to be on the lookout for the disease symptoms in your herd; don’t hide it. We all need to work together to continue the investigation. If you have a sudden drop in appetite and milk production in your herd, the first person you should call is your veterinarian and work through to get a diagnosis, whatever that might be,” he says.

“Secondly, we want dairy farmers to know that the veterinary community cares about you. And we certainly understand that this is a scary time. So make sure that you’re relying on your veterinarian and USDA and organizations like AABP for reliable information,” he adds.

Gingrich offers counsel for veterinarians as well. “Be aggressive with diagnostics, as the investigation is ongoing. Make sure that you are working with your diagnostic labs and state animal health officials to collect the appropriate diagnostics that we have posted on the AABP website. If you’re an AABP member, we have a reporting portal where you can identify the herds with this syndrome.”
