Selenium along with vitamin E are very crucial and play very important role in improving anti-oxidant status of dairy cows. Selenium should be in the organic form as seleno methionine and seleno cysteine. When fed in combination, according to one study conducted by us, it significantly improved glutathione peroxidase activity, FRAP value, IGg, IGm, IGa, milk fat, milk protein and FCM (4%). When selenium was given in the inorganic form no changes in blood or milk parameters were observed.
I strongly believe that dairy cows and buffaloes must be fed with selenium yeast, along with vitamin E.
In our study, vitamin E was given @ 300 I U per cow per day and the organic selenium was supplemented @ 0.3 mg per kg DMI.

Manget Ram Garg Good study. I have studied long ago in Denmark and having same results. However, sources of feed is important, particularly selenium in soil where roughage or corn grown and feeding of animals. it is also same in chicken that affects in Glutathione peroxidase activity. Definitely organic source is effective.

The article is valuable. In my experience, I have seen that when total selenium supply is over than recommended , some case of abortion increase. Yet over dosing vitamin E had no problem
