Rodney,

The quickest and most cost effective method to protect quality forage from being browsed by cattle is to use a Gallagher Electric Fence.  Usually a single or double strand of electric wire or tape powered by a solar charger will easily exclude cattle but allow adult deer to simply jump the fence.  This is different from a food plot protection fence where a single strand is placed three feet in front of a second row of fence with two stands.  Using Gallagher fencing, food plots can be established anywhere within the cattle pasture that provides an advantage to the crop and/or hunter.

This technique has been used and refined in Texas and other states where cattle have access to most of the properties.

Growing Deer together,
