Epi. 232 - Creating a Structured Internship Program in Your Practice Apr 21, 2025

Show notes

AABP Executive Director Dr. Fred Gingrich is joined by Drs. Al Martens and Nick Mayer from Waupun Veterinary Services in East Central Wisconsin. We are also joined by Katelyn Belding, a third-year student at Iowa State University who participated in a summer internship program at Waupun Veterinary Services.

Our guests discuss the importance of externships for exposing students to cattle practice, providing experiences for them, making connections for future employment opportunities, and is a way for veterinarians to give back to the future generation of cattle veterinarians. We discuss the differences between an externship, which is intended to be a shorter experience, and an internship, which at Waupun Veterinary Services is a longer summer program that provides a stipend for the student.

Students often face obstacles in gaining these experiences. This can include lack of a network to identify opportunities, financial barriers to participate, and locating housing. Practices that are interested in hosting students should recognize these barriers and work to address them. Our guests also discuss identifying a person in your practice to manage the externship and internship program. Waupun Veterinary Services also provides a pay incentive to veterinarians in the practice when they have students with them to encourage them to take the time to teach the student. It is also advantageous to introduce students to other veterinary opportunities in their community, such as industry and government-employed veterinarians that work with the practice. It is also suggested to have an intern at the practice develop a project, and Belding describes her project that she completed on her internship.

The AABP Foundation provides funding for students to attend externships. The AABP Foundation also provides externship grants for students enrolled in Historically Black Colleges or Universities (HBCU) through a grant from the Boehringer Ingelheim Cares Foundation. Students interested in attending practices in Wisconsin and are current or potentially future residents of Wisconsin can apply for the Wisconsin Rural Opportunities Fund (WROF) grant.

Epi. 231 - Update from the American Veterinary Medical Association Apr 14, 2025

Show notes

AABP Executive Director Dr. Fred Gingrich is joined by AVMA President Dr. Sandra Faeh Butler, AVMA Associate Executive Vice President and Chief Veterinary Officer Dr. Gail Golab, and AVMA Associate Executive Vice President and Chief Advocacy Officer Dr. Kent McClure.

Faeh updates us on the current AVMA membership, which includes over 108,000 veterinarians and represents at 2.9% increase in membership over the past year. One very important aspect of AVMA activities to bovine veterinarians is advocacy. We discuss how AVMA identifies advocacy priorities and uses AVMA entities and policy to develop this advocacy.

There are a number of issues that AVMA is currently providing advocacy for that are important to bovine veterinarians including access to critical drugs such as xylazine, access to antimicrobials for food animals, boosting the sustainability of rural veterinary practice, support of the Rural Veterinary Practice Enhancement Act, advocacy for the FARM bill, ensuring DEA regulations are compatible with ambulatory bovine practice, advocating against a mid-level practitioner position, and supporting the requirement for establishing a VCPR with an in-person visit and using telemedicine to support that existing VCPR.

Golab also provides information about the work of AVMA on the recent influenza outbreak in dairy cattle and poultry. AVMA plays a key role in collaboration with all stakeholders and convened a meeting last year with stakeholders across federal and state agencies as well as veterinary and producer groups representing bovine, swine and poultry groups. The result of this meeting was the development of the National Milk Testing Strategy to support nationwide surveillance of dairy farms.

AVMA guidelines are also important for veterinary medicine. Golab provides an update on the humane endings and depopulation guidelines, how they are developed and where we are in the new revisions for these guidelines. AVMA also recognizes that veterinary medicine, and food animal commodities, are globally influenced, and AVMA provides international advocacy to support not only bovine practice but also beef and dairy issues on the global market.

Our guests encourage bovine veterinarians to help AVMA in these advocacy efforts. This includes maintaining membership in AVMA, volunteering for committee and council membership, enrolling in the Congressional Advocacy Network, enrolling in the AVMA ambassador program, participating in the annual AVMA legislative fly-in, and donating to the AVMA Political Action Committee (AVMA PAC).

Epi. 230 – What Veterinarians Need to Know about the Animal Disease Traceability Rule Apr 07, 2025

Show notes

AABP Executive Director Dr. Fred Gingrich is joined by Sigrid Johannes from the National Cattlemen’s Beef Association to discuss the updated USDA Animal Disease Traceability Rule which took effect in November 2024. This rule is an update of the 2013 rule and there was significant stakeholder input and collaboration with USDA to develop the final rule.

It is important for veterinarians to understand the rule to work with their clients to ensure they are in compliance with the regulations. The main change to the 2013 rule is that the type of identification must be both visually and electronically readable. Other aspects of the 2013 rule remain largely unchanged. Specifically, this affects cattle moving interstate and are either dairy breed animals, sexually intact cattle over 18 months of age, and animals that are used for rodeo, recreational events, shows or exhibitions. All other classes of cattle, including those moving interstate direct to slaughter, are not impacted by this rule.

Johannes estimates that this rule affects 10-12% of the U.S. cattle herd and she also provides information about how producers and veterinarians can obtain free tags. We also discuss the importance of confidentiality and the information that is stored on tags. The information on the tag includes the EID number, and other information from producer records is not subject to freedom of information act (FOIA) requests. Producer confidentiality remains a high priority and is secure with this regulation.

Johannes also mentions the importance of a robust disease traceability system to protect cattle health as well as maintaining export markets and global competitive trade. This is important not only for producers, but also the sustainability of the cattle veterinary industry.

Veterinarians should familiarize themselves with the rule by visiting this link. General information from USDA APHIS can be found on this page. NCBA has also developed a backgrounder document for producers that veterinarians can use to assist their clients.

Epi. 229 – Assessing Bull Breeding Soundness Exam Parameters Following Vaccination with Modified-live or Killed Vaccine Mar 31, 2025

Show notes

AABP Executive Director Dr. Fred Gingrich is joined by Dr. Chance Armstrong and Dr. Jennifer Koziol to discuss a paper published in the AABP peer-reviewed journal The Bovine Practitioner. The journal is available open-access and the target audience is practicing veterinarians.

Veterinarians performing bull breeding soundness exams are often asked when they can vaccinate bulls, and much of the available research focuses on type and timing of vaccination on females. The objective of this study was to determine if and how multivalent vaccines (modified-live and killed) affect spermatogenesis in bulls, measured by the percentage of normal sperm morphology and progressively motile sperm over a complete spermatogenesis cycle in bulls.

Our guests walk through the results of the study which demonstrated no detrimental effect associated with the use of multivalent modified-live or killed viral vaccines on the sperm morphology of mature bulls over a 61-day period. This suggests that vaccination of mature bulls following a routine bull BSE or at the time of turnout could be performed with limited risk. Our guests emphasize the importance of the veterinarian performing a full BSE 30-60 days before the breeding season starts. Armstrong re-iterates the Society for Theriogenology (SFT) standards for the appropriate evaluation of bulls for breeding soundness. Koziol and Armstrong are the authors of the SFT Manual for Bull BSEs and you can find information at this link. We also review how stress, nutrition and lameness also affect bull fertility and the importance of the veterinarian performing this complete evaluation to identify satisfactory breeders for cow herds.

Finally, we discuss the new AABP Bull Breeding Soundness Examination Position Statement (find it at this link). This statement was developed by the AABP Reproduction Committee which ultimately states that this procedure is the practice of veterinary medicine and requires the expertise and knowledge of the veterinarian to perform. Our guests reiterate that this position statement is advocacy for the practicing veterinarian by AABP. If you are interested in reproduction, Armstrong and Koziol encourage you to join the committee by going to this link to email the committee chair. The email should include your name, veterinary school, grad year and your interest in the committee.

Epi. 228 – AABP Milk Quality Seminar Mar 24, 2025

Show notes

In this episode, AABP Executive Director Dr. Fred Gingrich is joined by Dr. Brandon Treichler and Dr. Justine Britten to discuss the upcoming AABP Milk Quality Seminar. The seminar will be held in Ashland, Ohio, May 16-17, 2025. This seminar is approved for 15 hours of continuing education in jurisdictions that recognize RACE approval. The fee for the seminar is $450 and a local hotel block has been secured for just $129 per night which includes breakfast. Attendees are also provided lunch on both days of the seminar. AABP is offering these seminars outside of the annual and recent graduate conference to expand our CE opportunities for members at a lower cost and less time away from practice.

Mastitis is the number one disease affecting dairy cows and it is important for dairy veterinarians to understand how to develop comprehensive milk quality programs for their clients. Treichler emphasizes that veterinarians are uniquely positioned to help their clients be successful and milk quality is an important part of that success. Although somatic cell counts in U.S. and Canadian herds have been on the decline, but clinical mastitis rates can be problematic on dairies. Britten will be leading the diagnostic portions of the seminar including correct plating, reading plates and discussing other mastitis diagnostics which will be clinically relevant and practical. We also discuss the farm visit portion of the seminar where we will participate in parlor observation, equipment evaluation, employee monitoring and training, environmental evaluation and stall evaluation.

This seminar will be useful to the novice milk quality consultant, and will also provide information for those wanting to advance their current skill set. This seminar is limited to 25 attendees, and you must be an AABP member to attend. Veterinary technicians who are AABP members are also welcome to attend and practices can send technicians to learn these skills to support the veterinary team.

Ep. 227 - Dairy Transition Cow Nutrition and Management Seminar Mar 17, 2025

Show notes

AABP Executive Director Dr. Fred Gingrich is joined by Dr. Phillip Jardon, extension veterinarian at Iowa State University and a member of the AABP Nutrition Committee. The goal of our podcast today is to discuss the upcoming Dairy Transition Cow Nutrition and Management Seminar. The seminar will be held in Ashland, Ohio, on April 25-26, 2025. This seminar is approved for 15 hours of continuing education in jurisdictions that recognize RACE approval. The fee for the seminar is $450 and a local hotel block has been secured for just $129 per night which includes breakfast. Attendees are also provided lunch on both days of the seminar. AABP is offering these seminars outside of the annual and recent graduate conference to expand our CE opportunities for members at a lower cost and less time away from practice.

Veterinarians are uniquely positioned to provide consultations for the transition cow program for their dairy clients. This can include everything from balancing the rations to trouble shooting when problems occur. Starting fresh cows off right is important to prevent disease, but also important for production and reproductive success. Jardon explains that there are many areas to explore in the transition pen through observation that does not involve balancing the ration. This seminar will include a consultation at a local dairy to teach these skills to attendees so they can go home and immediately incorporate these consulting skills into their practice or improve their current level of understanding.

Faculty includes Jardon and Drs. Jonathon Townsend, Jesse Goff and Jim Drackley. Jardon discusses the topics from each faculty member. Goff will provide presentations on macro and micro mineral nutrition and vitamin nutrition impacts on immunity, and DCAD discussions. Drackley will present on grouping strategies and transition cow ration strategies for balancing energy, fiber and protein levels to ensure success of the transition cow program and fresh cow health and productivity.

This seminar is limited to 25 attendees, and you must be an AABP member to attend. To find out more information and to register, visit this page. Find all AABP CE opportunities under the “Continuing Education” menu of the AABP website. All upcoming non-conference seminars are on this page.

Epi. 226 – From San Francisco to Dairy Practice – Dr. Michelle Schack Feb 17, 2025

Show notes

AABP Executive Director Dr. Fred Gingrich is joined by Dr. Michelle Schack, the keynote presenter for the 8th AABP Recent Graduate Conference. Schack grew up in the San Francisco Bay area, with no access to cattle farms or 4-H and FFA programs. She decided to become a veterinarian early in life, but then realized companion animal practice did not suit her needs and she became interested in large animal medicine as an undergraduate and cattle production medicine at University of California-Davis College of Veterinary Medicine. We discuss that only 18% of the U.S. population is from rural communities, and our recruitment efforts should focus on exposing all interested students to cattle practice and welcome them to join us!

Schack delivered the keynote presentation “Enhancing Sustainability through Animal and Human Well-Being”, and this presentation will be available to AABP members to view on our CE portal which is accessible under the Continuing Education menu of the AABP website.

Schack discusses the impact of everyone on the team providing care that affects animal well-being on every farm. She provides some tips for how to approach team members, managers and owners for addressing animal handling and promoting well-being. Approaching the conversation as a helper for the caregiver and the animal can be a good way to be non-confrontational. Providing training programs not only impacts the care for the cows and calves, but also improves employee satisfaction and retention. Schack is a co-founder of DairyKind, an online resource for caregiver training that can then be followed up with in-person training sessions. This creates an environment where cattle are cared for in an appropriate manner, caregivers are properly trained, and veterinarians are involved in the program to create billable hours.

Veterinarians are an important part of promoting well-being on farms for both employees and cattle. Start having conversations today with your clients to provide these resources and training sessions for well-being just as you do for other production medicine consultations.

Ep. 225 - A Follow-up Investigation of the Reported High Herd Prevalence of Bovine Viral Diarrhea in Dairy Farms in Georgia and Florida Feb 10, 2025

Show notes

AABP Executive Director Dr. Fred Gingrich is joined by Dr. Yung-Yi Mosley from the University of Georgia to discuss a recently published paper from the Bovine Practitioner to study the prevalence of bovine viral diarrhea virus (BVD) on Florida and Georgia dairy farms. The purpose of the study was to do a follow-up investigation from a previous study that demonstrated a 38% prevalence of BVDV in those states in 2015-2016.

Mosley walks through a general overview of BVDV including diagnostic testing and clinical syndromes that may result when cattle are infected with BVDV, including the development of a persistently infected animal (PI). She emphasizes that vaccination alone is not an effective control program for most herds and that testing for BVDV in purchased animals and biosecurity practices are important. Mosley stresses that if a producer is introducing pregnant animals, it is critical to not only test the dam, but also the fetus when it is born.

The objectives of this study were to evaluate the prevalence of BVDV in Georgia and Florida dairy farms and determine the circulating BVDV subtype in this region. The study involved 37 farms with a total of 57,000 cows and evaluated 90 samples. The study identified 10% of farms having a positive bulk tank sample. The type of BVDV found was Type 1b. Mosley discusses the significance of this compared to available BVBV vaccines. Mosley also discusses the findings of the survey that was administered to producers participating in the study.

Finally, we discuss how veterinarians can use the information from this study to screen bulk tank milk samples for BVDV. A bulk tank milk sample is a useful screening test and is accurate for up to 1,200 cows to detect a positive. Veterinarians should review their clients' BVDV control programs to evaluate potential risks and implement a comprehensive prevention program.

Epi. 224 What Do You Need to Know about New World Screwworm? Jan 27, 2025

Show notes

AABP Executive Director Dr. Fred Gingrich is joined by AABP member and Texas rancher Dr. Chris Womack to discuss the concerns about the New World Screwworm discovery in the southernmost state of Mexico. Womack discusses the history of this fly and an interesting story from his childhood of it being found on his father’s ranch in the mid-70s.

New World Screwworm strikes live tissue in all mammals and can be a serious risk to newborn calves as well as adult animals. Flies are attracted to fresh wounds where they lay eggs and the larvae feed on this living tissue. The pest has been eradicated in the mainland U.S. since 1966 with a few sporadic outbreaks. The USDA has had a collaborative relationship with Panama to prevent the pest from migrating north; however, it was discovered in an adult cow in Chiapas, Mexico in late 2024. This resulted in a shutdown of all cattle and bison from Mexico to the United States. Each year the U.S. fed cattle industry imports 3-5% of our cattle inventory from Mexico.

Treatment for infected cattle includes ivermectins and organophosphate dips. If the pest gets into wildlife, it will be very difficult to manage; therefore, control outside of the U.S. remains critical to the cattle industry. Control revolves around the release of male sterile flies into the infected areas so that females will not lay viable eggs. It is critical for all veterinarians to be vigilant, even if you are only treating small animals, because the risk of the pest coming in on a companion animal is also considerable.

Epi. 223 - Preventing Violative Drug Residues Jan 20, 2025

Show notes

AABP Executive Director Dr. Fred Gingrich is joined by AABP Past President Dr. Pat Gorden, a professor of dairy production medicine and clinical pharmacology at Iowa State University College of Veterinary Medicine.

We review the meaning of violative drug residues and the most common medications used in cattle that have historically been associated with violative drug residues. Gorden also reviews both how animals are selected for testing and how withdrawal intervals are determined by drug sponsors when going through the drug approval process. Of particular importance is the effect of disease on the clearance of drugs from the animal since the residue studies are performed on healthy animals for FDA submission.

Gorden reviews basic pharmacologic mechanisms for drugs and how disease state may impact drug clearance. He also reviews a study he performed that looked at severe clinical mastitis cows and the impact on the pharmacokinetics of ceftiofur in these animals. Veterinarians should utilize FARAD for withdrawal determinations and consider disease state on drug clearance.

Finally, Gorden offers suggestions for practicing veterinarians to review with farm managers and employees, including observations in the hospital pen or when treatments are administered. Ensuring correct protocol compliance, applying correct therapy, estimating the correct weight, extending the withdrawal interval on sick animals, ensuring the correct dose, route and volume of injection, and fully mixing suspensions prior to filling the syringe are all important items to check. Veterinarians are tasked with ensuring appropriate oversight on drug use on farms and regularly reviewing these steps is an important aspect of this stewardship principle as well as creating billable hours that are valued by the client.
