British scientists believe they can use gene editing to counter bovine diarrhea virus (BVD),
Their optimism arises from success in using gene editing to control a similar virus, classical swine fever.
The research is being done by the University of Edinburgh ,
Classical swine fever, also called hog cholera, is not in Canada, said the Canadian Food Inspection Agency.
But BVD is common in western Canadian beef herds and in feedlots, according to a factsheet published by the University of Calgary.
It can infect calves before birth, can prompt abortions, still births and weak calves. Other BVD symptoms include diarrhea, fever and impair the immune system so other diseases more readily infect calves.
There are effective BVD vaccines.
