Effects of graded levels of tannin-containing tropical tree leaves on <i>in vitro</i> rumen fermentation, total protozoa and methane production

Abstract

Ficus bengalensis, Au. integrifolis and Az. indica leaves are of interest in the enteric methane ameliorative strategies. Total mixed ration containing 10-15% ground F. bengalensis or Au. integrifolis or Az. indica leaves could be fed to ruminants to reduce enteric methanogenesis. However, in vivo trials need to be carried out to validate these in vitro results.
