ADVICE
ADD "E" TO IMPROVE
DAIRY RATIONS
Vitamin E in dairy rations has been a
hot topic lately because of the upgrading
of National Research Council require-
ments. Some of the reasons for raising
the levels in the diet are:
• documentation that Vitamin E and
selenium are involved in the disease -
prevention process
• an indication that Vitamin E levels
in forages are highly variable
• that Vitamin E can be used as an
antioxidant to prevent off -flavour prob-
lems in milk
Perhaps the most exciting aspect of
how Vitamin E works is its involvement
in disease -prevention. Vitamin E acts as
a biological antioxidant and, in conjunc-
tion with selenium, helps maintain cell
membrane structure. This function is
involved in disorders such as white
muscle disease and retained placenta.
Recently, the Ohio State Agricul-
tural Research and Development Centre
discovered a link between the incidence
of mastitis and supplemental Vitamin E
and selenium levels. The initial study
demonstrated a 37 per cent reduction in
clinical mastitis throughout the lacta-
tion when supplements were fed.
Further trials by Dr. Larry Smith at
Ohio showed:
• a 42.2 per cent reduction in infected
quarters at calving
• a 32.1 per cent reduction in clinical
mastitis overall
• that infections that did develop
were 45 per cent shorter in duration
The basic recommendation is to
provide adequate Vitamin E and sele-
nium to the lactating cow, but perhaps
more importantly to key in on the dry
cow period — especially the 30 days
pre -partum. Ohio State University is
also recommending injecting Vitamin E
and selenium 21 days pre -partum:
1. to ensure that each cow is receiv-
ing adequate amounts
2. to raise blood titre levels
3. because there may be some de-
struction of dietary Vitamin E from
heavy grain feeding (ie: lead feeding
pre-partum)0
