Just when I thought I knew it all, (or is it that I didn’t
want to learn anymore) I spent a day at the Saskatchewan Beef and Forage
Symposium in Saskatoon, this week, and got a bad case of information overload.
I was only able to catch 13 of the 17 presentations during
the day, but here are some of the highlights. (Many of the presenters were
students at the University of Saskatchewan (U of S) working on their Masters
Ward is working on a project to see if genetic testing might one day help identify cattle who could benefit from Vitamin A supplements to improve carcass marbling. Vitamin A does affect marbling and some cattle may have a genetic disposition to
better handle vitamin A than others. If genetic testing can identify
those cattle, supplements could be used to improve carcass quality.
Pratt, selected a glamorous project where she is collecting the liquid
from rotting carcasses to get a chemical analysis. The whole point of this
is, if there is ever a major disease outbreak and large numbers of cattle
have to be euthanized and buried, she wanted to evaluate the impact of
this liquid or leachate on soil and groundwater. It appears the leachate
would be very high in ammonium sulphate, phosphorus, chloride and other
compounds, so proper citing of these disposal grounds and even SRM
disposal is important to protect the environment.

is trying to determine if there is a way to identify overly
aggressive cattle in a beef herd.Some goofy heifers just make poor
mothers, and of course other aggressive females, at calving, injure and
kill ranchers every year. Some limited surveys she has done shows that 70
percent of producers report having ‘dangerous’ cows, and 70 percent of
those producers have been injured by cattle. Surprisingly only 50 percent
of injured ranchers say they culled overly aggressive cattle. (Maybe Brooke should be evaluating the 50 percent of producers who don't cull crazy cows).
Gannon, at U of S, is looking at the potential of using the bran from
wheat used in ethanol production as a feed source for feeder cattle. Research results are preliminary,
but it appears the high fibre bran can replace barley in a feed ration and
still produce good gains.
McKinnon, who is way to old to pass as a student, is currently Saskatchewan Beef Industry Chair in the Department of
Animal and Poultry Science at the University of Saskatchewan. He has, for
several years, been evaluating the use of Dry Distillers Grain (DDG) from
ethanol production as a livestock feed source. While a lot of the DDG used in Canada comes from corn
ethanol plants in the U.S., as much as 500,000 tonnes of wheat DDG is
produced in Canada. Looking at DDG used in backgrounding rations, McKinnon’s research shows wheat
DDG can be a very cost effective ingredient for backgrounding, however he notes it is high
in nitrogen and phosphorus, so any surplus nutrients end up in manure
making it a challenge to properly manage manure application so it doesn’t
overload the environment.
