Situation:?Highly pathogenic avian influenza A has been detected in poultry flocks in Edmunds and Hamlin Counties. The South Dakota Department of Health (SD-DOH) asks medical providers to be alert for influenza infections in patients with potential exposure to influenza A-infected animals within 10 days prior to symptom onset. Persons presenting with flu-like illness (fever, chills, cough, or sore throat) with or without conjunctivitis should be asked about contact with sick or dead poultry or other animals. SD-DOH staff are available for consultation by calling 800-592-1861.

3. Three new UK programs seek to boost student interest in equine, large animal vet careers [KY]

The University of Kentucky has secured three grants to help attract more students into veterinary sciences as the state and nation continue to struggle with a shortage of large animal vets.
The programs use "horses as a hook" to help connect interested students to the science behind animals, according to Meghan Wulster-Radcliffe, UK's director of strategy for equine initiatives.
The grants come from the U.S. Department of Agriculture, which has identified about 250 areas where specific veterinarians are needed across the country. In Kentucky, the federal agency recognizes five areas of need for veterinarians, the majority being food animal veterinarians in rural areas.
Wulster-Radcliffe said the three USDA grant programs help close the gap between interest in animals and a student's ability to apply the science.

Large animal veterinarians in North Carolina are eligible to apply for up to $25,000 in funds to help support their large animal practice.
The funding opportunity is available to veterinarians who practice in one of the 70 North Carolina counties with a population of 100,000 or fewer and that spend 30% or more of their patient care involved in large animal veterinary care.
These funds can be used for repayment of educational loans related to the recipient's veterinary degree, to purchase equipment or technology for use in their practice or any additional uses the advisory committee determines is appropriate to promote and develop large animal veterinarians to practice in the designated counties.
5. Health record analysis of one million cattle identifies early prevention as key to reducing feedlot respiratory deaths [Australia]

New research involving more than 1 million Australian feedlot cattle has found that the strongest predictors of death from bovine respiratory disease (BRD) are established before animals even enter the feedlot, highlighting the importance of preventive measures on source properties.
The study, led by Adelaide University in partnership with Apiam Animal Health and Meat and Livestock Australia, analyzed health and production records from 1,040,253 cattle across three Australian feedlots between 2018 and 2024, making it the largest Australian investigation of BRD-specific mortality conducted to date. It has been published in Preventive Veterinary Medicine.
While the overall mortality rate in Australian feedlots is very low (less than 0.5%), bovine respiratory disease is a leading infectious cause of illness and death in feedlot cattle and accounted for nearly 38% of all feedlot deaths recorded in the study.
Supplier history stands out
The team discovered that cattle from supplier properties with a history of elevated BRD mortality were more than four times as likely to die from the disease as cattle from lower-risk properties. This may provide a potential basis for using supplier history to identify higher-risk consignments before they arrive.
