The link between supplementary tannin level and conjugated linoleic acid (CLA) formation in ruminants: A meta-analysis

This meta-analysis was conducted to predict and assert a way to discover conjugated linoleic acid (CLA) formation in ruminant-derived products as problem solver of human health issues threated by plant-containing tannins. The objective was to expound, to compare, and to confirm the efficiency of tannins cultivating CLA formation whether using in vitro and/or in vivo study. A database was created using the ruminants with selectively 26 experiments comprising 683 dietary treatments as explained in vitro and in vivo methods that were applied as a statistical SAS 9.4 tool. Basically, increasing level of tannins leaded to an underlying decrease in CLA formation (p50 g/kg DM recommended. Secondly, the in vivo method was more suitable for directly observation that concerned in fatty acid transformation.
