Managing the habitat for proper nutrition should be the primary management goal. Supplemental feeding and/or planting of food plots are not a substitute for good habitat management. These practices should only be considered as "supplements" to the native habitat, not as "cure-alls" for low quality and/or poorly managed habitats.
To be most beneficial, supplemental feeding in particular needs to be integrated into an overall deer population and habitat management program that maintains the range in good condition. Feeding programs which provide sufficient additional nutrients to be of value to deer are expensive and take a long term commitment.
Although corn is commonly used as a supplemental feed, it is one of the poorest types of deer feed available and it should not be used as the only source of supplemental feed. Its low protein level (7-10%) is not adequate for the development of bone and muscle, especially at times when the protein levels of native forages is also low. The preferred method is to use a 16% to 20% protein pelleted commercial feed, fed free choice, from feeders distributed at the rate of at least one feeder per 300 acres located within or adjacent to adequate escape cover.
Deer are attracted to corn and it can be mixed with pelleted feed to get deer accustomed to utilizing the feeders. The amount of corn in the mix should gradually be decreased over time. Feeders should be fenced to keep livestock (and feral hogs if present) out but still allow easy access to deer, especially fawns. If net wire is used, the bottom should be raised off the ground (if hogs are not a problem), or there should be low spots on the top, to allow access to smaller deer.
The fenced area should be large enough to minimize creating a confined area that deer may be hesitant to enter. Supplemental feed should be made available throughout the year. Feed consumption will likely vary throughout the year, depending on deer's seasonal nutritional needs and the quality of the native forage. Refer to the TPWD bulletin "Supplemental Feeding" for additional information.
Although corn has limited nutritional value, it can be used as "bait" prior to and during the hunting season to attract and hold deer in an area for more efficient and selective harvest.
