TGE Virus Detected on Ontario Pig Farm

TGE Virus Detected on Ontario Pig Farm

Swift thinking of one Ontario pig farmer has resulted in early detection of Transmissible Gastroenteritis (TGE) virus.

In mid-June, a producer noticed vomiting and diarrhea in its nursing pigs. The farmer contacted the herd veterinarian, who took samples and sent them to the University of Guelph’s Animal Health Laboratory where TEG was diagnosed.

“TGE is a viral disease that has been present in the province for many years and causes vomiting, diarrhea, and high death loss in pigs,” read a notice to producers released by Ontario’s pork industry.

Signs of TGE are said to be identical to Porcine Epidemic Diarrhea (PED), a new disease which has spread to about 200 hog farms - spanning 13 states in the United States. Since the PED outbreak in the U.S., there have been no cases diagnosed in Canada.

The producer was praised by the industry for prompt response and handling of the situation. “The recent handling of an outbreak of TGE is an excellent example of how to respond to unusual clinical signs in a swineherd,” the statement read.

Ontario's swine industry warns that the risk of PED entering into Canada is greater with the disease rapidly spreading across the border. Producers are urged to be vigilant when implementing on-farm biosecurity measures.

The TEG health update was jointly released by Ontario Pork, Ontario Pork Industry Council, Canadian Swine Health Board, Swine Health Leadership, and Ontario Association of Swine Veterinarians.

Video: Dr. Emerson Nafziger: Nitrogen Fertilizer Rates for Corn

The Crop Science Podcast Show, Dr. Emerson Nafziger from the University of Illinois breaks down decades of nitrogen research. From the evolution of N rate guidelines to how soil health and hybrid genetics influence nitrogen use efficiency, this conversation unpacks the science behind smarter fertilization. Improving how we set nitrogen fertilizer rates for rainfed corn is a key focus. Discover why the MRTN model matters more than ever, and how shifting mindsets and better data can boost yields and environmental outcomes. Tune in now on all major platforms!

"The nitrogen that comes from soil mineralization is the first nitrogen the plant sees, and its role is underestimated."

Meet the guest:

Dr. Emerson Nafziger is Professor Emeritus of Crop Sciences at the University of Illinois at Urbana-Champaign, with degrees in agronomy from Ohio State, Purdue, and Illinois. His research has focused on nitrogen rate strategies and crop productivity. He co-developed the Maximum Return to Nitrogen (MRTN) model, which is widely used across the Midwest. His research spans N response trials, hybrid interactions, crop rotation effects, and yield stability.
