While there is usually still enough ß-carotene in young pasture grass and fresh hay, forage loses more and more of this valuable provitamin with longer storage. Breeding mares and stallions in particular have an increased need for the fertility-promoting ß-carotene, which can no longer be adequately covered by the basic feed. SALVASTAR KAROTIN is a special feed that improves the fertility of mares and stallions and thus increases the chances of pregnancy.
