Dear Dr. Nesrein,

I will share some data (as pdf) on the effects of tannins in sheep reproduction shortly.

I also strongly recommend you to seek (on the net) and read the papers of Prof H.Makkar (Austria) who is an world-wide expert on processing, analysing and using "tannins"(Tanniniferous oak leaves) in sheep nutrition and reproduction. I presume that he sould have also published a review data too. Back in early 2000's, we studied a common international IAEA-project of tanniniferos oak leaves under the local team leader of Prof Sedat Yildiz (Turkey).

Good luck, Regards

Omer
