The purpose of this study was to evaluate the
cumulative effect of recommended inorganic arsenic in a long
term exposure. Role of vitamin E which acts as first line of
defence in ruminants against pro-oxidant not much reported.
As the vitamin E requirement of all classes goat is 100 IU/kg
(Morand-Fehr 1981), therefore 100 and 150 IU/kg doses were
decided to see the antioxidant effect. Keeping in view the
above facts, the present investigationwas undertaken to assess
the protective effect of different doses of vitamin E against
arsenic induced changes in the oxidative stress indices and
immunological variables in lactating goats.
