    The Bovine Practitioner - AABP's Peer-Reviewed Journal

    The Bovine Practitioner - AABP's Peer-Reviewed Journal

    AABP Executive Director Dr. Fred Gingrich is joined by the associate editors for The Bovine Practitioner in this podcast to discuss the peer-reviewed journal published by AABP. The associate editors are Drs. Sarah Capik, Virginia Fajt, Miles Theurer and Aurora Villarroel. The Bovine Practitioner has been published by AABP continuously since 1967. There have been two previous editors of the journal, Dr. Eric Williams and Dr. Robert Smith. The journal is open access using the online journal system (OJS) through an agreement with Texas A&M University Libraries, and all volumes have been scanned into PDFs and are searchable at the article level. Access the journal by clicking this link. Listeners can register on the site to receive notifications of new publications as well as indicate if they are willing to serve as a peer reviewer for the journal. The Bovine Practitioner publishes articles that are relevant to the practicing cattle veterinarian and accepts submissions that are original research, descriptive studies (case reports, case series, innovative techniques) and review articles. The submission and peer-review process are managed online through the OJS and the journal now publishes accepted manuscripts at the article level. AABP does not charge submission, page or publication fees to authors. Practicing veterinarians are encouraged to partner with academic or industry colleagues to publish in the journal for assistance with study design and statistics. Associate editors are also willing to assist inexperienced authors who need information on publishing as well as providing contacts for collaborating with projects. We encourage all authors to read the author guidelines to ensure submissions are in compliance with general guidelines, formatting and submitting papers that are masked for the blinded peer-review process. Author guidelines can be found at this link.

    Lameness in feedlot cattle

    Lameness in feedlot cattle

    AABP Executive Director Dr. Fred Gingrich is joined by Sarah Erickson from Feedlot Health Management Services Inc., by Telus Agriculture, in Alberta, Canada. Sarah is currently enrolled in the Master of Science in large animal clinical sciences at the Western College of Veterinary Medicine, University of Saskatchewan, and hopes to obtain her veterinary degree after completion of her masters. 

    Lameness is a significant issue in feedlot cattle accounting for approximately 30% of all treatments in feedlot cattle, second only to bovine respiratory disease, and affecting over 3% of Western Canadian feedlot cattle. Cattle affected by lameness weigh close to 50 lbs less than healthy pen mates, but the economic impact is also influenced by treatment costs, labor, mortality and salvage slaughter. We discuss the most common conditions causing lameness in feedlot cattle which include toe tip necrosis, foot rot, arthritis, laminitis and digital dermatitis. There are unique challenges in managing these disease in feedlot versus dairy cattle due to the differences in husbandry between the two industries, but in both circumstances, lameness in cattle impact health, production and welfare. Erickson reviews a recent study performed on over 1.7 million head of Western Canadian evaluating the epidemiology of digital dermatitis, foot rot and toe tip necrosis. She discusses the risk factors for each disease such as sourcing, age, sex, feedlot size and days on feed. Veterinarians can play an integral role in assisting feedlots with development of protocols for diagnosis and treatment of lameness conditions, reviewing pain management and euthanasia protocols for affect cattle, development of prevention programs, and evaluation of the incidence in client yards to improve prevention and treatment programs.
     If you are interested in lameness and want to volunteer, a great place to start is the AABP lameness committee which can be found on this page. AABP committee resource files can be found at this link.

    Laboratory Diagnostics for Mastitis Pathogens

    Laboratory Diagnostics for Mastitis Pathogens

     AABP Executive Director Dr. Fred Gingrich is joined by Drs. Andy Lefeld, Justine Britten, and Allan Britten in this podcast brought to you by the AABP Milk Quality and Udder Health Committee. You can find information about the Milk Quality and Udder Health Committee on this page and find all AABP committee resources at this link. The Brittens manage Udder Health Systems with labs located in Washington, Utah and Idaho. Lefeld is a member of the Milk Quality and Udder Health Committee and a veterinarian at Maria Stein Animal Clinic in Maria Stein, Ohio, providing milk quality services to dairy farms.  
    Mastitis is the most costly disease in the dairy industry with an economic impact estimated at $2 billion annually. Our guests discuss the types of mastitis pathogens and the importance of identifying the pathogens causing mastitis on dairy farms to know if the infections are due to contagious or environmental pathogens. It is also important to obtain diagnostics to the species level for some pathogens. Monitoring pathogens can include bulk tank cultures, individual cow cultures, or string sampling. We discuss how veterinarians can get involved in mastitis diagnostic programs, including setting up and monitoring on-farm culture programs, in-clinic milk quality laboratories or utilizing an outside diagnostic lab. There are several newer technologies that labs now provide including PCR, MALDI-TOF, and chromogenic agars. Veterinarians have the opportunity to assist producers in developing diagnostic programs to manage mastitis on the dairy farm. We also discuss that a diagnostic test should be utilized if the results will alter an intervention, either treatment or prevention.

    Antimicrobial sensitivities on mastitis pathogens are not routinely recommended since an antimicrobial sensitivity test is unlikely to change the intervention on the farm due to the limited number of intramammary tubes available and the lack of break points for most intramammary antimicrobials. Finally, it is important for veterinarians to develop quality control programs for both in-house cultures as well as cultures from on-farm programs. One such program is the QMPS program from Cornell University. Veterinarians should discuss with their dairy farmers how they can utilize diagnostic testing as a part of a total milk quality control program.

    Extra-label drug use and FARAD resources

    Extra-label drug use and FARAD resources

    AABP Executive Director Dr. Fred Gingrich is joined by three AABP members on this episode of Have You Herd? where we discuss decision-making for utilizing extra-label drug use, working with producers for ensuring appropriate oversight of antimicrobial use, and utilizing resources from the Food Animal Avoidance Residue Avoidance Databank (FARAD). The three guests are current AABP Committee on Pharmaceutical and Biologic Issues members including Chair, Dr. Kevin Jacque from The Ohio State University, Dr. Virginia Fajt from Texas A&M University and Dr. Fiona Maunsell from the University of Florida and FARAD. 
    We start the conversation by discussing considerations for extra-label drug use in cattle, including the different production classes of beef and dairy cattle that should be considered and how this use may affect the determination of a withdrawal interval. The veterinarian of record is the party responsible for ensuring appropriate oversight of drug use and assigning that withdrawal interval, and our guests discuss that veterinarians should take pride in being responsible for extra-label drug use. Dr. Maunsell discusses the FARAD program, where it receives its funding and the fact it is an advisory, not regulatory, program. We discuss how veterinarians can improve the accuracy of information received from FARAD by filling out their online submission entirely and accurately. The group also discusses inadvertent prohibited drug use and how to communicate with FARAD to assign a withdrawal time as well as working with clients to ensure we correct the errors that led to the inadvertent use.

    Mental Health Resources for AABP Members

    Mental Health Resources for AABP Members

    AABP Executive Director Dr. Fred Gingrich is joined by Dr. Murray Gillies, AABP Board of Directors representative to District 12, and Dr. Charlie Gardner, chair of the AABP Mental Health Task Force, for this episode to discuss mental health and well-being initiatives being developed by AABP.  Gillies proposed the creation of a Mental Health Task Force to provide support to AABP members and create resources to aid in the prevention of mental illness and promotion of mental health. We discuss that there is a stigma associated with mental illness and normalizing the conversations around mental health can support our colleagues in bovine practice. Prevention of mental illness and improving our own mental health is important and we discuss various tips for preventive medicine for ourselves as well as tips on how to find a counselor. The AABP Foundation has recently supported the Veterinary Hope Foundation through a $25,000 donation, to fund the creation of peer support groups that are available at no cost to AABP members to join. Find out more information about the Veterinary Hope Foundation at this link and the partnership with AABP and how to join on this page. AABP members who want to support mental health initiatives through the AABP Foundation can donate to this fund on this page. We encourage all members to take the AVMA QPR training program to recognize and assist colleagues who may be struggling. Find out information about this resource on the AVMA Well-Being page. AABP also encourages members to consider submitting a story to the Humans of AABP Facebook page by contacting fred@aabp.org or gwren@aabp.org. The intent of the series is to normalize conversations around mental health and support each other. Stories can be posted anonymously.

    Bovine Neosporosis

    Bovine Neosporosis

    AABP Executive Director Dr. Fred Gingrich is joined by Dr. BJ Newcomer from the VERO branch of Texas A&M University to discuss abortions due to the protozoal parasite, Neospora caninum. Neosporosis is the most commonly diagnosed cause of cattle abortions and is seen in beef and dairy herds. Transmission of the etiologic agent can be exogenous through a canid host that ingests the cysts from aborted tissues and then passes them in feces to be ingested by cows, or vertically from dam to fetus in utero. An adult cow can pass Neospora to the fetus which can result in a positive calf that is born normally and is a risk for future reproductive failure, or result in an abortion, typically occurring in the 4 to 7-month gestation window. Newcomer reminds our listeners to work with their diagnostic labs to facilitate testing of aborted fetuses as well as testing adult cows for Neospora antibodies through serum ELISA testing. Control measures involve culling positive animals, aborting animals, and controlling fecal contamination from dogs in feed ingredients. We also discuss capturing the genetic value of positive cows through implementing advanced reproductive technologies and ensuring recipient animals are Neospora-negative. 
     This episode of Have You Herd was brought to our listeners by the AABP Reproduction Committee. Gingrich suggests that AABP members who want to volunteer to seek out a committee to join by going to the committee menu at https://aabp.org.

Great Podcast

This podcast has everything a Herd Check specialist wants and needs. Dr. Fred is diving deep and this is essential listening for those in the industry. The "Call me on the phone line, I'll put my arm up in your bovine" line in the song intro is hilarious and very clever. Great job AABP and Dr. Fred Gingrich.
