A cold and wet spring which delayed seeding and sprouting has resulted in a late harvest
throughout most of Saskatchewan, if not the Western Canadian Prairies. Although, a
long, dry and sunny fall could significantly improve the outcome, it is reasonable to predict that
the harvest will result in significant amounts of grain that is immature, frozen and or
sprouted. Discounted, frost damaged wheat, canola or barley can represent an opportunity for pork
producers. Producers should have the grain tested for fibre content (ADF and NDF) and use
appropriate equations to adjust the DE content. However, these equations are not accurate if the
damage is severe (bushel weight of 40 or below for wheat or 45 for barley). The energy content
of severely damaged grain should be discounted by 10% and/or it should be diluted with
undamaged grain.
If ergot or mould is suspected, again the grain should be tested. It should then be mixed with
“clean” grain to ensure the toxin does not exceed the recommended levels. None of this grain
should be included in rations destined for the breeding herd.
