A good solution is a bypass (rumen-undegradable)
seleniumthat is nowavailable fromProvimi.
This product increases the availability of selenium
to the animal and as a result it ismore effective
as an antioxidant at similar inclusion rates to the
inorganic and organic forms. The Ruprominmineral
buckets and the complete range of Rupromin
minerals nowcontainGrape PP andby-pass
seleniumfor improved immune status.
Vitamins andminerals
Apart fromGrape PP andby-pass selenium,
the Ruprominmineral products offer a
comprehensive supply of minerals and vitamins
to improve cattle health.
To support the immunity of your cows best,
Provimi has developed Rupromin ImmunoPlus
and Rupromin ImmunoBase. Its high vitamin E
and Grape PP content is effective in reducing
somatic cell counts and the number of mastitis
cases. Biotine and zinc improve the recovery and
the frmness of the keratin plug in the teat end
which wears off during milking. These minerals
therefore enhance the natural barrier function
of the udder. Organic zinc is incorporated in
enzymes and it is effective in protecting the cell
from the inside out against free radicals.
Copper is absorbed in the small intestine
and is needed in the formation of superoxide
dismutase, an important enzyme in the
protection of cells against free radicals. A
suffcient copper supply also prevents anaemia,
thereby maintaining the general health status.
To avoid minerals such as sulphur, molybdenum
and iron infuencing copper uptake Rupromin
ImmunoPlus contains organically bound copper
to guarantee a good uptake.
Specifc researchonGrape PP in cows shows a
strong improvement in the antioxidant status of
the animal as shown in Figure 3. This improvement
is greater than that shownby other extracts.
By-pass selenium
Another important antioxidant is selenium.
Selenium is necessary for the formationof the
enzymeGSH-Px. This enzyme helps to render free
radicals harmless and contributes to better udder
health. Selenium is available in an inorganic or
organic (seleniumyeast) form. There are limitations
withboth; inorganic selenium is partly converted
in the rumen into a formthat cannot be utilisedby
the cowand seleniumyeast is partly lost through
themilk.
