Salt and Minerals
Where legal, salt and minerals are easy and relatively inexpensive to put out for whitetails and are one of the best ways to get fairly accurate trail cam surveys. Deer love salt and hate minerals so will only eat minerals when they are "disguised" with salt so even a bag of mineral is in large part....salt.
Trace Mineral salt is by far the most the most economical yet most effective way to attract whitetails and when people ask me what to put out for a cam survey, this is what I recommend. 50#'s will last the season and deer typically dig huge craters, eating the soil/salt mixture over time. This of course allows them to get some minerals naturally but I usually add a bag of mineral to the mix.
When it comes to minerals it is important to remember that despite all the hype, university studies have shown absolutely zero benefits in regards to antler growth. Many people believe it is helpful but without cloning to whitetail bucks and feeding them identical rations...it is impossible to prove. Just be realistic about expectations and avoid spending your habitat budget dollars on expensive and ineffective commercial products.
Trace mineral salt will almost always provide rapid results in regards to attracting deer to a cam site and will generally be more effective if put out in mid to late winter but a friend of mine decided to try a bag in early summer and shared the results with me. A simple bag of TM salt for a round $7 produced 415 pics in 19 days, 329 of which were buck pics...
The lick was placed near a pond where deer normally travel to drink
and in this case apparently in a summer buck bedding area where bachelor groups live
Using the cam survey he can begin to identify bucks by age structure and begin to come up with a management plan
For 7 bucks...he is gaining a tremendous amount of information about the whitetails on his farm and if he continues to maintain this lick in subsequent years it will be even more heavily used and the information he gains invaluable for his management goals.
I have a client where i Have put out salt and minerals but he felt he might see more activity if we added some commercial salt/mineral mix....which I did but I doubted we would see any significant results. In the meantime I thought it would be fun test various commercial mixes against my own TM salt/livestock mineral
I have a lick that I have used for nearly 15 years now and it varies from 500-1500 pics per card pull so I decided to record the # of pics and note the dates, start and stop...such as shown here
6-28-2012 Start
7-10-12 Stop...660 pics
I picked up some commercial mixes
Noted the high concentration of salt in each....
along with various other ingredients
In each one
Keep in mind that each one of these weighs only a few pounds and cost as much or more then 50#'s of salt, most of course contained some minerals but a 50# bag of minerals is roughly $18-25
I placed marker flags in the existing lick
and emptied the contents of each bag by the appropriate flag
noting the heavy activity by deer digging the rock hard bone dry soil/salt in the lick
and deer currently using it
Noted the start 7-10-12
and stop 7-23-2012 973 pics (keep in mind that before I kept records some pulls were in 1200-1500 range)
I was curious if there was a commercial mix that was more attractive to deer then...salt, something I felt I already knew the answer too but as with everything I share...I want to
know the truth and have the facts clearly proven.
Would deer ignore the salt and choose the commercial products...or not? Out of 973 pics....only 4 deer even sniffed the commercial products let alone ate them and all the rest continued to eat the dirt salt/mix already there.
None of the older bucks even approached the commercial mixes
nor did the number of bucks visiting the site increase although I am sharing more pics from this batch then the first, actual activity did not increase
Note the line of fresh TM salt applied and deer using it, although most preferred the salt already mixed in the dirt
In time...as rain washes the various products into the soil I expect they will indeed use all of them at some point but it is certainly clear that in no way are these products more attractive then plain old...salt. They also do not have the ability to produce ginormous racks...only age and genetics can accomplish that.
Provide salt and free choice minerals but get more bang for you buck by buying 50# bags from your local feed store or farm and fleet and don't be misled into believing that any food or mineral will have a significant impact on the antler growth of wild, free roaming whitetails with normal, healthy food native food sources available to them...there is simply no verifiable evidence to prove otherwise.
I will update the results of my tests over time including into next year but the is more to this then meets the eye and relates to food sources and over all management.
Whitetails rarely travel far and often less then a 1/2 a mile if their needs are being met so knowing this we can see that neither food nor minerals can attract deer from miles away. On farms I manage most bucks will never (other then rut) travel from one end to the other of a 300 acre farm...so do not expect a mineral or food source to perform miracles.
Cover first, hidden year around food sources, age and genetics...in a nutshell those are the key ingredients to holding and harvesting big whitetails on your farm...
