From: Keith Thomas <<I don't have any comparisons of the fatty acid content and profile of popular sources of red meat between, for example:
(a) wild cattle (b) grass-fed farmed cattle (c) feedlot cattle raised on different foods (for example, with and without a significant fish-meal component). -- Does anyone know of such sources?>>
Keith,
There's a comparison of grass fed vs grain finished bison meat here -
