, the egg industry could serve as an example of how to slow the disease but also shows how difficult it can be to eradicate
Bird flu is typically fatal to chickens and turkeys within days of an infection, leading to immediate mass killings of birds. That's not true for cows. Many egg operations even use lasers and install special fencing to discourage wild birds from stopping by for a visit., the current outbreak would be much worse, said Jada Thompson, a University of Arkansas agriculture business professor. Still, maintaining such vigilance is difficult, even if the cost of allowing disease into an operation is so high, she said.
The dairy industry also could tamp down disease spread by limiting the movement of lactating cows between states, Poulsen said.The egg industry also is hopeful researchers can develop vaccines for poultry that could be quick, inexpensive and effective. Workers can't give shots to the millions of hens that might need a vaccine, but industry officials hope a vaccine could be distributed in the water the birds drink, in the pellets they eat or even before birds hatch from their eggs.
After hopes that Bear 178 would walk off her injuries and survive the car crash that left the grizzly limping, the bear affectionately known as Nakoda has died in Yoho National Park, Parks Canada officials confirm.On the evening of June 6, as wildlife management staff were repairing fencing along the Trans-Canada Highway near the Lake O'Hara access road, they attempted "to encourage the bear to spend time away from the roadside," read a Parks Canada statement.
