“What is the best thing to plant in my food plot?”
Have you ever ever requested this query? As College Extension professionals and wildlife scientists, we get requested that query so much. The seek for the “magic bullet” plant has yielded many nice discussions, however regardless of deer diets being closely studied by researchers and noticed by hunters, the reply has by no means been clear. You’ve in all probability heard deer hunters argue which forage is greatest to plant, and even that deer prefer to eat a sure species of plant on one property however keep away from it on one other. May each statements be proper? Or unsuitable? The crux of all of this dialogue lies with how deer resolve what to eat and why.
Reading: What is the best food plot for deer
In a collaboration between the Mississippi State College (MSU) Deer Lab and the College of Florida D.E.E.R. Lab, we introduced some readability to this difficulty by evaluating how vitamins affect which crops deer choose to eat, and what that might inform us about selecting the perfect meals plot forages and habitat administration typically.
Failure to contemplate that deer want far more than simply protein might obscure our understanding of what’s really occurring.
Which crops deer choose to eat and why has lengthy been debated in science. The perfect speculation to elucidate weight loss plan choice thus far was primarily based on many years of analysis with cattle, sheep and goats. It has been demonstrated that animals choose crops primarily based on their each day and seasonally fluctuating dietary necessities. Sounds easy, proper? The difficult factor is that animals have to steadiness the consumption of vitamins so that they keep away from poisonous quantities of anyone nutrient whereas nonetheless assembly the necessities of all different vitamins.
Most of what you have got realized about deer forage preferences in all probability includes some type of protein because the forex for rating forage high quality. Actually, few research have thought-about greater than three or 4 vitamins at a time when attempting to know why deer select to eat what and when. What’s extra, dietary necessities might range from deer to deer identical to with people. And, necessities range significantly primarily based on life stage occasions: antler development of yearlings verses mature bucks, or between antler development and the rut; or early being pregnant vs. lactation phases for grownup does. Failure to contemplate that deer want far more than simply protein might obscure our understanding of what’s really occurring. We designed an experiment to contemplate a big selection of vitamins in a wild deer herd to attempt to higher tackle what deer select to eat and why.
We established buffet-style experimental meals plots on a Mississippi property that was dominated by loblolly pine stands managed for wildlife habitat. We adopted regular food-plot protocols when cultivating the fields, utilizing herbicide to kill standing vegetation and a disk to arrange seed beds. We additionally utilized lime and fertilizer based on soil evaluation suggestions from the MSU Soils Lab.
We planted every area with 15 common cool-season meals plot crops bought from the native farm provide retailer – nothing fancy. You’ve heard the phrase “everything but the kitchen sink.” Effectively, that’s what we needed to do on this experiment: give deer dietary selections from a range of crops, lots of which have their very own distinctive nutrient profiles, so deer might combine their weight loss plan to satisfy their wants.
Every area contained equal-sized, adjoining plots of ladino white clover, crimson clover, arrowleaf clover, balansa clover, berseem clover, pink clover, winter wheat, bob oats, Elbon rye, rape, turnips, chicory, ryegrass, and Austrian winter peas. That covers most of what the looking group crops of their meals plots. Plots throughout the “buffet” have been randomized in every area in order that the identical two forages weren’t adjoining in every area and to account for the chance that plots on the sting or close to trails might get extra deer motion by likelihood. We additionally included a fallow plot to account for random deer visits not related to feeding.
In complete, we planted eight of those buffet-style fields throughout the property. We surrounded every area with electrical fencing on the time of planting to exclude deer till all crops might change into established. This was essential as a result of we didn’t need late-growing crops to be ignored as a result of they weren’t but obtainable. As well as, we randomly positioned a small exclosure cage in every plot and a trail-camera on the perimeter of every plot to watch deer exercise.

We began trials as soon as all crops had established. For every trial, we eliminated the electrical fences from two fields and picked up samples from every plant to measure the focus of 14 vitamins: crude protein, protein solubility, an estimate of fiber content material known as NDF, calcium, phosphorus, magnesium, potassium, sodium, iron, zinc, copper, manganese, molybdenum, and sulfur. Additionally, we measured the plant biomass in every plot to make sure deer weren’t simply selecting the plant that supplied essentially the most forage on the time.
We recorded deer use of every plant with trail-cameras for 14 days after which stopped the trial and put the fence again up. We didn’t need deer to be pressured to alter which plant they have been consuming as a result of they ate all of their favourite, nor did we would like the sector to be obtainable when different trials have been operating. Plant species mature at totally different charges, so operating the trials sequentially and never on the identical time resulted in the identical crops altering in relative nutrient composition over time. That allowed us to find out if deer simply appreciated one plant greater than others or in the event that they have been chasing vitamins.
What did we discover?
It was instantly apparent that deer weren’t simply consuming the identical crops again and again. They modified the order of choice in each trial. Apparently, we might predict in what order they would choose them primarily based on how the focus of vitamins was altering in every plant species – deer have been really chasing vitamins!
Generally, they have been avoiding crops with excessive ranges of sulfur, and so they secondarily ate crops with excessive ranges of crude protein and excessive digestibility. In different phrases, avoiding toxicity was most essential to deer, and assembly the calls for of different vitamins was completed secondarily.
As soon as we dug into previous analysis, the story began to unfold. We discovered research of livestock that reported sulfur toxicity is comparatively widespread in herbivores. Additionally, many research spotlight crude protein being wanted for a lot of bodily features and that crude protein is commonly missing within the surroundings, particularly throughout sure occasions of the 12 months. Lastly, it is smart that they’d keep away from toxicity first and secondarily attempt to acquire the vitamins they want. Consider it this manner: If you happen to eat one thing toxic, it could possibly kill you, however more often than not lacking a meal simply makes you hungry. Deer’s priorities in weight loss plan choice appear to be programmed with that in thoughts.
Total, because of this there isn’t any magic crop that may all the time greatest meet your deer’s wants all year long.
What does this imply?
We all know what you’re considering. “I need to go find the plant that has the most protein and least sulfur,” proper? No! There are some essential issues to contemplate from our experiment.
Keep in mind that nutrient necessities rely on life phases, and our experiment occurred throughout the post-rut in late winter or throughout early antler development and gestation within the spring. Throughout these occasions, crude protein could also be restricted within the surroundings and thus turns into extremely wanted within the weight loss plan. That doesn’t imply the identical is true at totally different occasions of the 12 months.

Additionally, our deer herd was in pine forest that was thinned to low tree densities and burned regularly to maximise wildlife habitat high quality. A few the predominate forbs in these communities, primarily based on different research performed on the property, are notably excessive in sulfur. In different phrases, the deer on this property have been doubtless already consuming naturally occurring forages that contained excessive quantities of sulfur, making meals plot forages with excessive sulfur ranges extra unpalatable, and have been subsequently averted. In one other location, with a distinct plant group, the context is perhaps totally different and deer would alter which crops they most well-liked and averted.
Total, because of this there isn’t any magic crop that may all the time greatest meet your deer’s wants all year long. The truth is that these various observations by you and your looking buddies might all be proper and may be as a result of totally different circumstances.
So what do you have to do?
When relating our findings to people, it could appear foolish to assume that one plant will resolve a deer’s dietary wants. Give it some thought this manner. What’s your favourite meals? Why don’t you eat that meals for each meal? We’re guessing the reply to that isn’t associated to availability. Then once more, why will we even have to ask somebody that query? Why is it not the identical meals for everybody?
We are likely to assume we have now misplaced our primitive dietary instincts and stroll round in a relentless state of satiation, which ensures we get the vitamins we want, and sometimes sufficient to retailer in reserves. Regardless of that, we nonetheless do have dietary instincts (and meals cravings) that result in us various our personal weight loss plan though we might all the time have entry to our favourite meals. These instincts additionally trigger dietary preferences to range extensively from individual to individual. We love Thanksgiving leftovers, which is mostly all kinds of nutritious meals. After a number of days, although, we’ve had our fill and would somewhat keep away from turkey and dressing for some time. Our dietary preferences are dictated by what vitamins our our bodies want, and what you want is consistently altering and isn’t the identical from individual to individual. We’ve all had these bizarre meals cravings, which have been scientifically linked to our physique pleading for a sure nutrient.
The one method you may actually make sure to meet each deer’s dietary calls for on a regular basis is to present them the chance to decide on. As you have got in all probability learn on this web site earlier than, range is vital!
Why would we count on one plant to be greatest for deer? Even whether it is well-balanced, as within the instance from Thanksgiving, wouldn’t deer develop an aversion to it over time? The short reply is there’s not one plant that’s greatest, and even if you’re offering one persistently, that doesn’t imply deer will lose curiosity. As an alternative, deer will use no matter crops or meals assist them meet their dietary calls for and won’t use crops that don’t. Furthermore, seasonal stresses reminiscent of harsh winters or droughts trigger vitamins within the surroundings and deer dietary must range. Plus, and that is the place the argument between buddies ensues, the background nutrient availability on all properties is totally different, and so is what vitamins your deer will select and when.
The one method you may actually make sure to meet each deer’s dietary calls for on a regular basis is to present them the chance to decide on. As you have got in all probability learn on this web site earlier than, range is vital! It’s crucial to handle your looking space to maximise plant range all year long in order that deer can select the crops they should fulfill their dietary calls for. Meals plots is usually a very efficient complement to these dietary calls for, however they need to be regarded as a complement to, and never a substitute for, good habitat administration.
Variety inside a plant group is essential, however so is a range of plant communities throughout your property. You hear it on a regular basis – use daylight and soil disturbance to enhance range. Whereas that’s completely true and usually the factor that’s lacking in a administration plan, there’s worth in having range in plant group administration methods as effectively. If you happen to lease property or are in any other case restricted to meals plots to handle diet, we suggest you employ a wide range of plant species each in mixes and in single species plantings. The difficult half in selecting food-plot crops is to translate what your deer try to let you know about their wants into which crops can greatest complement these wants.
We hope this data is useful in explaining the complexities of deer weight loss plan choice and managing your property to maximise deer diet. You possibly can be taught extra about deer biology and administration by trying out the MSU Deer Lab and UF D.E.E.R. Lab web sites, social media and the podcasts.
