2 hours ago
In this episode of "DocTalk," we join Dr. Dan Thomson and Dr. Dave Steffen at the University of Nebraska in Lincoln to delve into pathology in cattle, particularly inherited diseases. Dr. Steffen, with over 35 years of experience, specializes in perinatal issues, investigating birth defects and inherited diseases in cattle. He collaborates closely with major breed associations like Hereford, Angus, Simmental, and Red Angus, often serving as a go-to expert when issues arise, especially with sire-related concerns.
When cattle owners suspect an issue, they typically involve a local veterinarian, who may then contact Dr. Steffen. Utilizing digital technology, veterinarians can share images or videos for initial assessment, potentially saving the need for transporting animals over long distances. Dr. Steffen's work spans a broad spectrum, from investigating diseases caused by environmental factors to researching one-off mutations occurring in early embryos, often necessitating complex genetic analysis.
One ongoing project involves investigating hydrops pregnancies in Simmental cattle, a condition characterized by severe abdominal enlargement in mid-gestation. This research is crucial for the breed due to its devastating impact. Dr. Steffen's lab actively collaborates with breed associations and welcomes reports and samples, particularly from purebred animals, to further their understanding of inherited diseases.
Throughout the episode, the emphasis is on collaboration between cattle owners, veterinarians, and research institutions like the University of Nebraska's Veterinary Diagnostic Lab. By leveraging expertise and resources, they aim to address emerging issues and advance knowledge in bovine pathology.

"DocTalk" is back with Dr. Dan Thomson, joined by his esteemed colleague, Dr. Dave Rethorst, for an insightful discussion tailored specifically for ranchers. In this episode, the focus is on the crucial topic of developing heifers.
Dr. Thomson kicks off the show with a warm welcome, setting the stage for an engaging conversation. Dr. Rethorst, a seasoned veterinarian deeply entrenched in bovine medicine and beef cattle production, brings his wealth of experience to the table.
The discussion begins with the selection process for heifers, emphasizing the importance of choosing those born in the first 21 to 30 days of the calving season. Dr. Rethorst highlights the advantage of early-born heifers in reaching breeding weight sooner, laying the groundwork for successful reproduction.
Moving forward, the conversation delves into the strategy of exposing a larger number of heifers than needed for breeding, allowing for a rigorous selection process to identify the most fertile candidates.

"Doc Talk" is back with a focus on pink eye, a common and costly issue in the beef industry. Dr. Brent Meyer, a seasoned veterinarian and national expert in beef cattle medicine, joins the show to shed light on this pervasive problem. Pink eye, caused by various organisms including Moraxella bovis and Moraxella bovoculi, results in significant losses for the industry, both in terms of performance and market value.
Dr. Meyer emphasizes the importance of understanding the biology of pink eye and its transmission dynamics. Vaccination plays a pivotal role in prevention, but timing is critical to ensure optimal immune response. With vaccines primarily targeting Moraxella bovis, producers must adhere to strict timelines to bolster immunity before the peak of fly season.
Treatment options, including antimicrobial agents like tetracyclines and Tobramycin, are discussed alongside practical approaches such as eye patching and shading to aid recovery. Early intervention is key, as delayed treatment can lead to severe complications and widespread outbreaks within herds.
Prevention strategies extend beyond vaccination and treatment. Controlling fly populations, managing pasture conditions to minimize corneal damage, and addressing internal parasite burdens are essential components of a comprehensive approach to pink eye management.
Dr. Meyer underscores the importance of environmental factors, such as UV exposure, pollen, and tail flicking by cows, in exacerbating pink eye risk. By implementing proactive measures, producers can mitigate the impact of this costly disease and safeguard the health and productivity of their cattle.
"Doc Talk" continues to be a valuable resource for ranchers, providing expert insights and practical advice to address pressing issues in beef cattle management.
