Two grazing trials conducted at different locations in Kansas
evaluated feeding Monensin to grazing yearling cattle. In one trial
Monensin was fed with and without implant treatments of diethylstilbestrol
or Ralgro. Monensin increased weight gain on summer grass; diethylstilbestrol
and Ralgro implants also increased weight gains, and the combination
of Monensin with either implant was more effective than Monensin
alone.
