When considering the management of white-tailed deer, unless your property is game fenced you should realize that adjacent lands are also included in the home ranges of many of the deer on a ranch less than several thousand acres in size. Only those deer within the interior of a really large ranch may have home ranges located totally within the ranch, while those in a wide band around the ranch’s perimeter likely move back and forth onto adjacent lands. The quality of a ranch’s deer population will in large part be dependent on both the habitat quality and population management strategies (i.e. hunting pressure and deer harvest) on both your and neighboring lands.

The key to producing a productive and healthy white-tailed deer population is dependent upon the quantity, quality, and variety of food plants produced by the habitat or range. Food availability can be improved in the following ways:

1. Harvesting deer, including does, to maintain total deer numbers at or below the capacity of the habitat.

2. Stocking the range with a moderate number of domestic animals, preferably those that do not directly compete with wildlife, and utilizing some form of a deferred-rotation system of grazing.

3. Controlling invading “noxious” woody vegetation, such as excessive brush species that are not needed for cover. This will reduce competition between plants species and increase the production of grasses for cattle and the production and availability of browse and forbs preferred by deer. It is recommended that your property be a mosaic of 50-60% wooded/brush with the remainder in scattered openings and/or food plots.

4. Avoiding the stocking of excessive numbers of exotic big game animals or at least keeping their numbers at a low level, since exotics compete with white-tailed deer for browse, forbs, and mast. If you are really interested in producing trophy white-tailed deer, stay away from competing exotics.

A ranch must be divided into at least two pastures before even the least complex two pasture/one herd deferred-rotation grazing system can be implemented. If not cross-fenced, the land manager would need to have access to other areas where livestock could be moved to during the prescribed rest periods. Electric fencing is a lower cost and less labor-intensive alternative to barbed wire for dividing a ranch into multiple pastures.

For a deferred-rotation grazing system to be most effective, all the pastures in the system should be more or less equal in size and/or have similar grazing capacities (e.g., pastures on the most productive, deep soils of a ranch would have higher livestock grazing capacities and should therefore be smaller than pastures on shallower, less productive soils).

What do deer eat? Deer eat mostly browse (leaves, twigs, shoots of woody plants and vines) and forbs (weeds and other broadleaf flowering plants). They do eat some grass, but only when it is young, green, and succulent. Sheep, goats, and exotic game species compete directly with the whitetail for preferred deer foods.

Deer food shortages usually occur during late summer and winter months. Adequate forage is usually available during the spring and fall seasons because of mild temperatures and increased rainfall. A variety of foods and habitat types is essential to good deer production and survival.

Deer eat a variety of plants, and different plant species become more important at different times of the year and importance can even vary year-to-year depending upon environmental conditions. The following plants are examples of some good deer foods which are readily eaten by deer when and where they are available. (more…)

It is commom knowledge that deer need food, water, shelter and space for survival. When a casual observer sees the countryside with abundant trees and plants it may appear that deer have plenty to eat. But that is not necessarily the case. First, some plants are not edible. Second, some plants are not palatable. And lastly, some are only availalbe at certain times of the year. White-tailed deer use three major plant groups as food.

They are: 1) forbs, which consists of broadleaf herbaceous weeds, 2) browse, which consists of leaves and tender twigs of woody plants, and 3) grasses. Deer flat-out prefer forbs, but these plants are normally available only in certain seasons and if rains do not come at the right time, they may not be available at all. (more…)

While white-tailed deer are ruminants like cows, but their diet selection is much different. Cattle are grass-roughage eaters, have a relatively large rumen compare to body size, and depend heavily on grasses for their diet. Grasses are relatively low in crude protein and digestibility when compared with legumes or forbs (broadleaf weeds).

Because of these nutritive parameters, grasses have a longer residence time in the cow rumen. Longer residence time increases rumen microflora (bacteria and protozoa) degradation and digestion of the forage. Thus, for grass-roughage eaters like cattle and sheep, residence time is quite long and rate of food passage is slow. (more…)

In some circles, you will still hear people talk about the old barren doe that lives in a particular part of the ranch. This line of thinking blames poor fawn production on the idea that many older does do not get pregnant. In reality, if the doe isn’t bred during the first estrous period, she will be receptive again 28 days later. This explains the high breeding success in white-tailed deer, even when bucks are scarce. It was recorded in one Texas study, that on average, 92 of every 100 does sampled were pregnant.

White-tailed deer are known for producing twins. In the previously mentioned study, over half of the does examined had twins. Triplets, however, were not common, and the occurrence of triplets was less than two percent. Quadruplets didn’t show up at all in the study. There were more male fetuses than female fetuses. Males represented 56 percent of the unborn fawns over the three years of the study.

Believe it or not, big bucks are both born and made! The whitetail bucks on your property may be born with great genetics, but if they don’t get what they need, they may never show their true potential. On the flip side, some bucks will never meet your expectations simply because they are genetically doomed. It’s not their fault, but not all bucks are born with the same genetic code. So how do you get maximum antler growth from your deer herd? Antler development (main beam length, antler spread, basal circumference, and number of points) is dependent upon three factors: nutrition (quantity and quality of food), age, and genetics.

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.
