Two Weeks with No New PED Cases in Manitoba Cause for Optimism

Farmscape for July 31, 2017 New tools being used in Manitoba appear to be helping bring the spread of PED in the province under control. Since the end of April almost 60 swine production sites in Manitoba have been confirmed infected with Porcine Epidemic Diarrhea. On Thursday Manitoba Pork hosted a PED information session in Steinbach to update producers on the situation. George Matheson, the Chair of Manitoba Pork, says there have been no new cases since July 14. Clip-George Matheson-Manitoba Pork: We're organizing a manure management group for the infected farms. Of course equipment can become infected and we don't want a positive farm infecting a negative farm just by the transfer of manure equipment and spreading must be done soon. Lagoons get full. That's one approach we're taking. Manitoba Pork has decided to employ a Swine Health Officer, a full time position, just to manage the situation with the help of the Manitoba CVO. We've had three staff members, M

A New and More Virulent Hog Infection Invades Manitoba

Dr. Blaine Tully   - Canadian Association of Swine Veterinarians Farmscape for July 28, 2017 The President of the Canadian Association of Swine Veterinarians says swine veterinarian in Manitoba have stepped up their focus on addressing a new more virulent strain of Porcine Reproductive and Respiratory Syndrome. A new more virulent strain of PRRS, a viral infection that affects pigs of all ages and stages of growth, has been identified in Manitoba. Dr. Blaine Tully, the President of the Canadian Association of Swine Veterinarians and a partner with Swine Health Professionals in Steinbach, says genetic sequencing to determine whether it's related to strains experienced in Manitoba or other parts of the country have shown that its kind of a lone wolf. Clip-Dr. Blaine Tully-Canadian Association of Swine Veterinarians: We have about 12 or 15 farms, the majority of which are in southeast Manitoba but we do know there's farms in the Interlake and out into central Manitoba that h

Thanks to climate change, forest fires will likely become more common and widespread in Canada.

Environmental Research Letters Control fire -- NWT, Canada. (USDA Forest Service photo.)  As summer weather becomes increasingly drier and warmer, the risks of forest fires increase and their manageability decreases. A new study has modelled the key forest fire factors in boreal forests within the framework of changing climate models, and the results aren't hopeful: future forest fires will likely rage stronger and be much more difficult to contain than ever before. Researchers looked at three main predicting factors in forest fires: forest fuel types (in other words, what burns up in a forest fire: species of trees in the forests, type of forest and shrub cover, presence of lichens, wood chips or mosses on the ground surface); weather scenarios for the next 80 years; and fire behaviour (how the fire will spread, how fast it will travel, how intense it is, etc.) Their findings showed that the proportion of days in fire seasons with the potential for unmanageable fire w

Industrial hog production is leading to devastating issues for Manitoba

Vicki Burns and Janine Gibson. For the last three decades, hog production in Manitoba has become increasingly industrialized with the number of pigs per barn jumping to the thousands and the number of actual pig producers dropping from over 14,000 in 1971 to a mere 200 today. The pigs that are the basis of this industry are often referred to as animal units. The production system is under constant pressure to produce more piglets at less cost, resembling an industrial assembly line. The pigs never see the light of day or have the opportunity to root in straw or breathe fresh air. How far we have moved from family farming to this industrial model, where thousands of animals are kept inside buildings with minimal human contact, feed is automated and they must live above pits of their own feces and urine. This industrial hog production that dominates the Manitoba landscape is resulting in devastating issues that are in the headlines now. Porcine Epidemic Diarrhea (PED) has n

Hog Barn Fires – Where’s the Humanity?

Image
By Vicki Burns About a month ago, three thousand, five hundred pigs died horrible deaths in a hog barn fire near New Bothwell, in southern Manitoba. Sadly, it was just the latest in what has become an all-too-familiar occurrence in this province. Trapped in a fiery inferno, the animals would have likely suffocated in the smoke before the flames actually took over. It’s hard to imagine the terror and panic that must have gripped them in those moments. Firefighters battling such disasters say they’re often haunted for a very long time by the sound of their screams. The animals that perished there, bring the total number of pigs to be burned alive over the past decade in Manitoba to 64,000. Surely you’d expect a rational, caring government to respond by immediately tightening fire safety regulations. Instead, it’s doing just the opposite. It’s moving to change building codes to allow for fewer fire alarms, fewer smoke detectors and cheaper fire walls! And surely you’

Will God Save Us From The Wildfires?

by Larry Powell Did you hear them interview Walt Cobb on CBC Radio this week about the BC wildfires?  They asked him if he thought, as the world's leading climate scientists do, that wildfires have become "the new normal." Here's his response. “I don’t necessarily agree with that. There’s always been changes…Like my wife said the other morning…this is in somebody else’s hands… God has lined up what’s going to happen. And we’ll have to live with that." So who is Walt Cobb, you ask? Some ordinary guy off the street? Not exactly. He is the Mayor of Williams Lake, B.C. (l.) That's a city of 10 thousand - now almost a ghost town. It was ordered evacuated due to unprecedented fires burning in the region. Does he strike you as a guy who has a clue about the science?

The cycle of mercury pollution in the Arctic tundra

Image
Nature Human activity has been a major source of mercury pollution in  the Arctic, and a new  study   has identified the form most often  taken by the pollutant: gaseous elemental  mercury  (GEM). The  present  News & Views  article discusses how the Arctic tundra  acts as a major sink for mercury, as the local plants uptake GEM  from  the atmosphere; and  what this means for the global mercury  cycle as  global temperatures warm. Isotopic data  collected in the  original study  by Obrist  et al.  reveal that GEM accounts for 90% of  the  mercury in plants,  and the uptake of GEM by plants is  especially  high in the summer. Since  plant matter decomposes  into the soil,  the Arctic soil may soon become  a substantial  mercury sink. ======== Editor's summary Anthropogenic activities have led to large-scale mercury pollution in the Arctic, but it remains uncertain whether wet deposition of oxidized mercury via precipitation and sea-salt-induced ch

Parisitic birds use oil and gas infrastructures to prey on prairie songbirds - Study.

Image
Royal Society Open Science  We're only beginning to find out all the ways in which industrial activity disrupts the ecosystem, and a new bird study gives yet another example of the unexpected ways in which human activity affects the local fauna. Researchers at the University of Manitoba have found that the presence of oil and natural gas infrastructure—such as fences, power lines, and transmitters around oil wells—in Canada's Northern Great Plains helped boost the number of brown-headed cowbirds by four times. Cowbirds are a parasitic species who lay their eggs in other birds' nests, forcing others to raise their brood. The parasitic species uses oil and gas infrastructures as perches, and the availability of perches makes it easier for these birds to find their brood hosts.  Savannah sparrow. Photo by  D. Gordon E. Robertson Cowbirds' abundance in the area could hurt another grassland bird species, the Savannah sparrow, which often falls victim to the parasitic
