Huskers aim to crack code of major swine virus

Sep 04, 2023

Two University of Nebraska-Lincoln scientists have received a $627,000 federal grant to study a viral disease posing a significant threat to the swine industry worldwide.

Porcine reproductive and respiratory syndrome virus is widespread, causing reproductive failure in sows and major respiratory illness in pigs of all ages. In addition, the virus modulates the pig’s immune system, making the animal more susceptible to other infectious diseases. The costs to the U.S. swine sector from PRRSV annually total an estimated $1.1 billion.

Hiep Vu, associate professor of animal science, is the co-director of the research project, funded by a three-year grant from the U.S. Department of Agriculture. The other co-director is Sarah Sillman, assistant professor with Nebraska’s School of Veterinary Medicine and Biomedical Sciences and the Nebraska Veterinary Diagnostic Center.

The project will examine how PRRSV infects swine macrophages, the immune cells that recognize, engulf and destroy harmful intruders, including viruses and bacteria.

Video: You Be The Judge: Evaluating 8 Breeding Rams!

It's time for some honest feedback here at Ewetopia Farms! Today, we’re showing you all eight rams we used for breeding this year. Instead of just presenting them, we thought it would be fun to create a “Ram Report Card” — where we point out both their strengths and areas for improvement.

But here’s the twist: you be the judge! In the comments, let us know what you like about each ram and what you think could be improved. No ram is ever perfect, but every one of them brings something valuable to the flock. By sharing perspectives, we all learn more about what to look for in good breeding stock.

At Ewetopia Farms, we raise registered Suffolk and Polled Dorset sheep, focusing on high-quality genetics, structure, and friendly temperaments. Evaluating breeding rams is part of the bigger picture of building stronger flocks — and we’re excited to share the process with you.
