There is a lot that is not known about how white-tailed deer affect their habitat under different densities with and without supplemental feed. But, that’s exactly what a research project initiated on two South Texas ranchesd hoped to determine — the effects of deer on native vegetation.

To accurately conduct the research, six 200-acre enclosures were constructed on both ranches. In addition, they were divided into 3 pairs — each with target populations of 10, 25, or 40 white-tailed deer. One of each pair was supplemented with a free-choice (all you can eat) pelleted supplemental ration and the other was left to forage from only native forbs and browse. To document changes in habitat condition, canopy cover and biomass were estimated annually.

Many landowners and hunters consider supplemental feeding an important factor in deer management and a source of nutrition when native forage is inadequate either in quantity or quality. Under certain conditions a supplemental feeding program can help. However, most deer feeding programs which provide sufficient additional nutrients to be of value are quite expensive.

There is a distinct difference between feeding and baiting white-tailed deer. Maintaining deer feeders from October through December is a common practice on many ranches to attract deer to hunting blinds during the hunting season. Unfortunately most of these baiting efforts cease just before additional feed is really needed by the deer — in late winter. Supplemental feeding is most-beneficial during stress periods. Stress periods for deer are usually encountered when the protein content of the forage is at a low level during severe winters, dry springs and dry summers. (more…)

White-tailed deer habitat consists or food, water, shelter, and also space. Thus, food plots and supplemental feeding only impact the nutritional carrying capacity of a particular piece of property, not the total or actual carrying capacity. Assuming there is both adequate water and cover, supplemental feeding can greatly increase the number of the local deer population.

However, one thing to keep in mind is the amount of space and and habitat per deer decreases as the population size increases! More deer in an area mean less area for each individual deer. This may not be a problem if the number of deer is below the carrying capacity of the area, but this rarely seems to be the case with white-tailed deer.

One of the arguments used by those in support of supplemental feeding is that it not only enhances the nutrition and resulting health of the deer, but that it could possibly take pressure off of the natural vegetation by decreasing deer browsing. Unfortunately, there is little data to support this and plenty of data to refute it. (more…)

Managing for proper nutrition in white-tailed deer is important for good body condition, good fawn production and recruitment, and maximum antler growth. Good nutrition can be accomplished by doing three things that involve proper habitat management, supplemental feeding, and the planting of food plots.

Most everyone is familiar with the benefits of supplemental feeding (high-protein food, often pellets), but it can be expensive and it promotes the urge to artificially maintain excessive numbers of deer. With that said, supplemental feeding is not a bad thing, but it must be combined with other sound deer population management practices. (more…)

Question: A friend and I are considering starting a supplemental feeding program for the white-tailed deer population on his farm where we hunt. Our goal is to, over time produce larger, healthier bucks and does, as well as attract and holding a larger population of high-quality animals for hunting.

We are planning to implement food plots as the main approach to this end, but we are also considering supplemental feeding during the winter, when the does are carrying fawns and the bucks are shedding and preparing for the growth of the coming years antlers.

In my research on supplemental feeds, have I found several articles suggesting that supplemental feeding increases the chances of the transmission of diseases like ‘blue tongue’, which is normally associated with deer using the same watering hole as an infected animal. (more…)

The white-tailed deer is the most popular big game species in the United States. Landowners and ranch managers are becoming more interested in intensive deer management strategies including supplemental food plots in order to conserve and further enhance deer populations, in some cases in areas with rapidly decreasing amounts of deer habitat. The establishment of supplemental food plots can be an important deer management strategy which has become widely accepted throughout the southeastern part of the U.S. out to east Texas.

However, it should be noted that most plot plantings are not aimed at improving nutrition of white-tailed deer despite the fact that much of the southeastern deer range provides substandard nutrition for quality deer production. This is compounded by the fact that often times the number of deer (deer density) is greater than the number of animals the habitat can support under optimal body and antler growing condition. (more…)

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.

The buck to doe ratio over much of the United States is probably somewhere around 1 buck per 3 to 6 adult does. This ratio is considered satisfactory for good production and recruitment of white-tailed deer if one is interested in a quick turnover in the herd. Basically, a sex ratio in favor of does can increase the size of the deer herd very quickly. As a result, many young bucks and does of all ages are available for harvest each year. This is good for maximum production, but is not necessarily beneficial for optimal quality production.

Ideas on the ideal buck to doe ratio can be quite varied and controversial in some cases. Depending upon the part of the country you are located, the age of the person you are talking to, and a person’s general management philosophies, you will most likely get different answers from every individual you ask. But you know what, they may all be correct. There is no single correct answer for every property out there. However, there are some good rules of thumb that could help you out.

If you want to harvest a high number of deer each year, then maintaining many more does than bucks will definitely get you there. For example, let’s just say your hunting property is 500 acres. Assuming the proper carrying capacity for this land is roughly 50 deer (1 deer/10 acres) then a buck to doe ratio of 1:4 would mean your deer herd is comprised of 10 bucks and 40 does. If you have an overall fawn crop of 50%, meaning 20 fawns survive through the summer. With this in mind, you must now remove an excess of 20 deer on your property come fall hunting season to keep the overall population size in check with the available habitat. (more…)
