AABP Executive Director Dr. Fred Gingrich reviews a paper published in The Bovine Practitioner with the first author Madeline Mancke from Kansas State University. The objective of this study was to determine potential associations between Cardiac Troponin I (cTnI) serum concentration of cattle at initial bovine respiratory disease (BRD) treatment with the risk of retreatment or mortality at 60 days. 

BRD is the most significant disease in beef cattle and is a major cause of morbidity and mortality. Developing prognostic tools may be valuable for managing individual cases. cTnI is a protein that is released into the circulatory system after myocardial damage and may be useful as a biomarker for prognostication of BRD cases.

Mancke walks through the results of the paper which demonstrated that 8/318 samples had high cTnI levels and animals with high cTn1 concentrations had a significantly greater probability of not finishing the 60-day post-enrollment period. Cattle with high cardiac troponin concentrations at initial BRD treatment were more likely to have negative clinical outcomes but, in this study, very few animals had high cTnI levels. Mancke provides information about potential future research opportunities to better manage BRD cases in the feedyard.

AABP Executive Director Dr. Fred Gingrich is joined by Dr. Chris Chase, Emeritus Professor in the Department of Veterinary and Biomedical Sciences and Dr. Curt Vlietstra, Senior Professional Services Veterinarian with Boehringer Ingelheim. This episode is sponsored by Boehringer Ingelheim, manufacturer of the Pyramid line of cattle vaccines. Find more information about Pyramid/Presponse vaccines by visiting this page. 

Adjuvants are a critical component of vaccines, but they can be an overlooked factor when putting together a vaccine program. The three roles of adjuvants serve in vaccines are creating a danger signal for the host, help the immune system recognize the antigen and to protect the antigen. 

Historically, there has been some skepticism around vaccinating young calves early due to the presence of maternal antibodies. Our guests discuss what role vaccines serve in a calf program while recognizing the importance of colostral immunity and the purpose it serves. Adjuvants can serve an important role in young calves to help with a vaccine-induced immune response. Our guests discuss the METASTIM adjuvant, how it differs from other adjuvants, and the role it plays in boosting immunity even in the face of maternal antibodies. 

Veterinarians play a critical role in developing vaccine programs for their clients' herds. This not only includes ensuring that the appropriate vaccines are selected for the herd, but also making sure that nutrition, specifically vitamin and mineral nutrition, is appropriate, stress is minimized, and vaccine storage and administration is correct. We close the podcast by discussing the future of vaccine and adjuvant technologies that veterinarians should be aware of and how these potential uses can improve cattle health.

AABP Executive Director Dr. Fred Gingrich provides an update on AABP membership dues in this episode of Have You Herd? The mission of the AABP is to provide support, continuing education and advocacy for current and future veterinary professionals and the cattle they serve. The vision of AABP is to serve society as leaders in cattle health, welfare and productivity. 

The current AABP dues year is July 1 to June 30. This dues year was established by the AABP Board of Directors in 1983 to reflect the timing of the Annual Conference in the fall. Much has changed at AABP since 1983 which has resulted in CE offerings year-round. This includes the Recent Graduate Conference, webinars, podcasts, free online CE, online publications, and AABP seminars outside of our conferences. The board developed a task force to develop recommendations for changing the dues year to the calendar year. The reason for the change will be to align the dues year to our fiscal year, distribute staff workload more evenly throughout the year, and allow the organization to have a more consistent cash flow based on current expense cycles. The change in our dues year to the calendar year will take effect this year.

Veterinarian members, graduate students and registered veterinary technicians will have two options when renewing their dues which includes either a 6-month renewal at 50% of the annual dues rate, or an 18-month renewal at 150% of the annual dues rate. Members who select a 6-month renewal will be invoiced for the 2026 dues year in the fall/winter. Members who select an 18-month renewal will not be invoiced again until the fall of 2026. 

Gingrich discusses the three buckets of activity for AABP which includes continuing education, advocacy for cattle veterinarians, and support for the initiatives of the AABP Foundation. All buckets have increased greatly over the past several years with expanded CE options, increased advocacy on a state and federal level, and increased grants and scholarships administered by the AABP Foundation. 

Gingrich encourages all cattle veterinarians, graduate student veterinarian members and credentialed veterinary technicians to join our organization to support our efforts and take advantage of our resources. He also welcomes veterinary student members to join AABP to ensure they are eligible for student member benefits through AABP and the AABP Foundation.

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. Find all externship grant funding opportunities under the Students menu of the AABP website at https://aabp.org. 

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).

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. 

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.

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. 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. 

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. 

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.
