Does selection of Ionophore in Animal Type mean that ionophore will be fed?
Selection of ionophore on the Animal Type page will increase the calculated net energy for maintenance (NEm) value of the diet by 12%. But, a feed containing an ionophore such as Rumensin, Bovatec or Posistac must be fed at the proper levels to achieve this NEm increase. For example, Rumensin is fed at levels between 11 to 33 mg/kg dry matter; Bovatec at 36 mg/kg dry matter and Posistac at 100 mg/head/day for feed efficiency. The ionophore level of the diet is calculated in the Ionophore column of the Input page. See manufacturer’s directions for the product fed.
