The use of brown rice grain as corn grain replacer in dairy cow diets was investigated. The
following treatments were evaluated: zero, 33, 63, and 100%. The experimental diets were
iso in protein, energy and fiber levels. Eight multiparus Jersey cows were used. A replicated
Latin square experimental design was applied. The inclusion of brown rice had no effect
(P > 0.05) on dry mater intake and their constituents, apparent digestibility, production and
milk composition, feed efficiency and blood chemistry profile. Therefore, the brown rice
grain can be used replacing corn grains alternative feedstuff in dairy cow diet
