When the harvest is brought in and the pigs start to be fed with the new
grain, problems with the productivity of the pigs are often seen. Reproduction
problems, poorer gain and an increased mortality often occur when feeding with
newly harvested grain is started up. Extra vitamin E prevents
When the grain is harvested there are still a lot of
biological processes going on in the grain. These processes continue until the
grain is sufficiently dry for storage and this may take 1½–2 months. The
activity is biggest at unripe and moist grain. Therefore the grain should not be
harvested until it is ripe and should the harvest get moist, then it should be
dried in a hurry. At gas-tight storage of the grain the lack of oxygen will stop
the activity of the grain.
In grain there are enzymes, which ripen the seeds.
When the grain is grinded these enzymes become active. The by-product of this
enzyme activity is peroxides and free radicals. These substances are aggressive
to the cell level, and in this way the animals' ability to grow and thrive is
reduced. The good old "news" is that vitamin E can neutralize these aggressive
This phenomenon about
newly harvested grain is also called fresh-grain-poisoning. The negative impact
on the productivity results in poor reproduction and reduced gain at the pigs.
In the worst case several pigs die due to lack of vitamin E. New insights in
vitamin E seem to indicate that there also should be focus on vitamin K when
extra vitamin E is applied. Trials have shown that an increased consumption of
vitamin E also increases the need for vitamin K. Increased frequency of
bleedings from the stomach/intestine system are symptoms in the herd by lack of
vitamin K.New supplementary vitamin E product
developed a vitamin E product, which contains both vitamin E and vitamin K. The
product is called Suplex E-50000/K/Selenium. For every tons feed 1-1.5 kg is
used. Remember to hold in readiness for use before harvest. Then problems with
fresh-grain-poisoning can be avoided.Related website:
