Supplemental Feeding of Deer: Protein Pellets

It’s summer time in Texas and hot, dry weather is wreaking havoc on white-tailed deer habitat. That means deer will be hitting supplemental feed sources where they are available harder than ever. In fact, I’ve already heard from numerous hunters and landowners that whitetail are really hammering protein feeders, and this is on properties that provide relatively good deer habitat. Unfortunately, it looks like things are going to get worse before they get better. That has got everyone, deer included, feeling a little uneasy.

It’s the antler growing season for bucks right now, so that means game cameras have already been deployed. Reports indicate that the majority of bucks have anywhere from 3-10 inches of antler growth and that there are still a good number of does that have yet to domino (give birth). Guys in the pastures as well as camera photos are also seeing a good number of fawns already on the ground. Everyone is aware that natural foods are low, but deer are needing a lot of high quality nutrition right now.

If ever there was a time to supplement deer with free-choice protein pellets, that time would be now. Not only will deer manager after deer manager tell you first-hand what the addition of protein pellets has done for whitetail deer found on their properties, but respectable research from many different camps has found that protein pellets (16+%) really do make a difference for white-tailed deer in a number of ways.

There are many reasons to feed protein pellets, with the most cited one being increased antler growth for bucks. Other positives of this form of supplemental feeding include improved body condition in all deer, which translates into more milk production for lactating does and better muscle and skeletal growth for fawns later into the summer. Deer, both bucks and does, that get a good start the first year of their life will be superior animals down the road.

With natural foods on hold (at best) and deer nutritional requirements on the rise, feeding protein to deer seems like the thing to do right now, but there can also be some issues that arise that come along with the management practice. The first one that comes to mind is, well, cost. Let’s face it, the price tag of the feed alone can get expensive, but then there are also transport and labor costs.

With a white-tailed deer density that is appropriate for the habitat, a general rule of thumb is to estimate average consumption at about 3/4 pound of feed per day per deer day over the course of a year (even though the majority of properties do not provide pellets during October, November, and December). This number varies depending on the rainfall each year and the amount of natural forage deer eat, but averages out to about 275 pounds of protein pellets for each deer on an annual basis. That’s about $55 in feed. How many deer are found on your property?

Another issue that arises with the supplemental feeding of protein pellets to whitetail deer is increased reproduction, as in higher fawn survival. Now, this many not sound like much of a negative, but it really can be depending on the deer management objectives of a landowner or hunter. This phenomenon is something many well-intending managers do not realize until several years into their management program. I will focus more on this topic in the near future, but until then let’s keep an eye out for those whitetail fawns, bucks in velvet and maybe even a rain cloud?

Habitat Conditions Bad, Deer Hunting Good?

With the official start of summer almost upon us and whitetail bucks rapidly putting on new antler growth, it is never to early to speculate about the fall white-tailed deer hunting seasons in Texas. Unfortunately for everyone, dry weather has kept a damper on many deer and habitat management practices to date, but poor habitat conditions may help hunters across the state this fall.

Most folks know that dry weather is not good for wildlife. Deer hunters are also aware that low rainfall equates to below average antler sizes for bucks relying on natural forage to get them through the year. That being said, it comes as no surprise that severe drought across the state has dimmed what usually is a bright outlook for white-tailed deer quantity and quality.

Deer Habitat Improvement Through Prescribed Burning, Fire

The wildfires plaguing various parts of Texas have got me thinking a lot about prescribed burning over the past few days. Prescribed burning, prescribed fire, controlled burning, or however one refers to it, is a tool used for many purposes. It is commonly used for white-tailed deer habitat improvement, but it can also be used to prevent, contain and extinguish wildfires.

In recent years, prescribed fire for range and wildlife habitat improvement has increased substantially. Granted it’s not for everyone, but many land managers understand the utility of this management cost efficient management practice (which is also a naturally occurring process).

Prescribed burning is a tool used by land managers for increasing forage quality for livestock, reducing and controlling invasive brush species and for actively managing wildlife habitat. In fact, prescribed fire can accomplish many objectives simultaneously. For example, one fire be used to reduce brush cover, eliminate fine fuel loads, increase forage quality for wild and domestic animals, and improve wildlife habitat for deer, turkey and quail. Fire sets back many woody species and eliminates fire intolerant ones such as ashe juniper (cedar).

Why Use Prescribed Fire?

Prescribed fire is used to reduce fuel loads (existing dead and dormant vegetation) and reduce the threat and severity from wildfires should one occur. Prescribed fires also reduces woody plant encroachment and are beneficial for many native plant species in a way mechanical and chemical management treatments cannot duplicate.

Wildlife, both game and nongame species, also benefit from prescribed fires which results in new plant growth and restoration of habitats which they use both for both food and cover. Benefits from prescribed fire include:

Reduce hazardous fuels, protect communities from wildfires
Reduce the spread of pests and disease
Provide habitat and forage for game and nongame species
Recycle nutrients back into the soil
Promote native species
Promote a diverse natural landscape

Prescribed Burns Often Misunderstood

Most landowners realize that not all fire is bad. Wildfires are bad when the loss of life and property are involved, but prescribed, controlled fires are not. Often times, the vegetation found on a particular property requires a managed fire, not a wildfire, to come along at the right time and under the right conditions in a controlled manner. This is prescribed burning.

Once the objectives of the fire are determined and the conditions under which the fire should be used are established, it is only then than a prescription for carrying out the fire have been developed.

The prescription should include landowner objectives, personnel requirements, firebreaks and environmental factors such as air temperature, relative humidity and wind direction and speed. The bulk of the work takes place long before the first flame hits the ground. However, proper land management after the burn is essential for both wildlife and livestock. Cattle frequently concentrate on a burn because forage is more palatable and nutritious. However, this does not mean these grass-eating machines should be released onto burn sites immediately. As with any major event, some rest is warranted afterword.

Fire is a Tool for Active Managers

As with many tools, the quality of the work depends on how good you are with the tool. Prescribed fire for brush management/control and deer habitat improvement is no different. Without a doubt, experience is the best teacher of fire behavior. Inexperienced managers can learn a lot by observing prescribed fires lit by other folks. Considerable knowledge can be learned about fire behavior relatively quickly, but it takes years of experience to get good, but even then you will not (should not) feel totally confident. Even trained professionals do not lose their fear of what fire can do.

The benefits of controlled burning for wildlife are well documented. Burning is good for deer because of the nutrient-rich browse and forbs that respond post-fire. Fire also knocks back many of the root-sprouting browse species that have outgrown the reach of deer. Fire promotes native grasses, which in turn creates better quail nesting habitat, improved water infiltration, and drought-tolerant forage. Additionally, fire is a relatively inexpensive management tool, especially for landowners interested in controlling cedar. Costs can range from $2 to $8 per acre depending on the size of the burn, prep work, and personnel needs.

To wrap up, prescribed fires have different uses depending on the objectives. The most common use of controlled burns is to reduce fuels such as pine needles, leaves and dead herbaceous vegetation such as grass and weeds. Controlled burning can also be used for brush control and quail, turkey and white-tailed deer habitat improvement. Although prescribed burning is a very effective tool, it can be incorrectly applied. Prescribed fire, just like any habitat management practice, should only be implemented once the need has been completely evaluated and deemed effective for achieving the desired objectives.

Rainfall, Habitat and Antler Growth

Managing for good white-tailed deer habitat on a property is the key to maintaining a healthy deer herd. Plain and simple, deer in good body condition are more productive than deer in poor condition. A problem many landowners face is that Mother Nature does not always do her part. This is the major reason why supplemental feeding has become an integrated part of deer management on many ranches.

A property can generally have good deer habitat, but that does not necessarily mean that the plants found on the property are in good condition. Rainfall makes a big difference from year to year. In fact, research conducted in South Texas, on what was coined the “South Texas Buck Project,” by the Caesar Kleberg Wildlife Research Institute at Texas A&M-Kingsville found that spring rains explained 70% of the year to year variability in buck antler size.

Spring rain and antler growth were highly correlated, meaning bucks grew larger antlers following wet springs and smaller antlers following dry ones. During the South Texas Buck Project, researchers classified spring rains as those occurring during March, April and May. And over much of the whitetail’s range, it is during this time of the year when good rainfall can produce bountiful crops of high protein forbs and set up browse plants for the long, hot, and typically dry summer. If the rains do not arrive, then deer can forget about the would-be protein buffet.

Okay, so I will admit that South Texas is much different than many parts of the white-tailed deer’s range, including most parts of Texas, but the results of this study are a bit staggering. The data collected during the South Texas Buck Project conclusively found that spring rains alone accounted for as much as a 20 inch shift in gross Boone and Crockett scores for mature bucks! These findings really illustrate the importance of precipitation, habitat condition and food availability to any landowner or hunter interested in deer management.

So this all makes enough sense, but how can it help hunters on their property given that they can not control the rain? Well, no one can turn on the faucet that makes it rain, but hunters can control whitetail food availability through management practices such as maintaining proper livestock grazing rates, brush management, prescribed burning, supplemental feeding and managed deer harvest. Allowing deer to grow older is one way to produce more mature bucks, but age is not the only factor that affects antler size.

In mature bucks, rainfall determines whether that 20 inch shift I mentioned previously ends up being 20 inches up or 20 inches down. Food availability is of utmost importance in allowing old bucks to reach their genetic potential. For hunters interested in trophy buck management, I would seriously considering shooting any buck 5 1/2 years of age following a wet spring. Why? For the simple reason that the chances of getting two good years in a row are slim, and therefore antlers are not likely to be better the next year. During a dry spring, such as this one, hunters may want see if those deer can add that 20 inches back on next year.

White-tailed Deer Range and High Fences

They have become a part of the Texas landscape. Landowners that have them claim that they are critical for white-tailed deer management. Those that don’t either dislike them or simply can not afford them. Some people, hunters included, hate them. Hard working men make a living building them. “They” are high fences, often referred to as game fences. Like it or not, it seems high fences are here to stay, but a question that has undoubtedly crossed the minds of many deer hunters is, “What impact does a high fence have on the movement of white-tailed deer?”

Game fences are typically 8 or 10 feet in height, so there are high fences and then really high fences. Ask just about anyone and they will tell you that high fences are deer proof—deer inside the fence can’t get out and deer outside the fence can’t get in. This belief is disturbing to hunters and landowners bordering high fenced properties because it seems more and more ranches are turning to boundary fence that consist of high fence. I can see both the pros and cons of high game fences, but neither of them is so compelling that I want to drink to the proverbial Kool-Aid. That being said, high fences make it much easier to manage a deer herd. Continue reading “White-tailed Deer Range and High Fences”
