Adisseo solutions discussed in this topic
Smartamine® MAX
The newest member of the Smartamine® rumen-protected methionine family.
Rumen-protected methionine option for herds balancing metabolizable methionine. See the brochure for specifications.

Smartamine® M
Rumen-protected methionine (pH-sensitive coating releases methionine in the abomasum).
Supplies metabolizable methionine — typically the first-limiting amino acid in North American dairy rations — to support milk protein and fat yield, health and reproduction.

Selisseo®
100% hydroxy-selenomethionine (OH-SeMet), a pure organic selenium source.
Builds selenium reserves that support antioxidant defense, immunity and milk quality through calving, heat stress and other challenges.
