North American Salt's trace mineral brick is a compact 4-pound supplement block for cattle, horses, pigs, and wildlife that need consistent access to six core micro-minerals beyond what plain salt provides.
Zinc, manganese, cobalt, copper, iodine, and iron are included to support growth, immune function, and overall health across livestock classes.
The 4-pound size suits individual stall use, small herds, and wildlife supplementation where a large 50-pound block would be impractical. As with all mineral bricks, keeping it out of direct rain slows dissolution and extends the block's useful life.

Whether This Mineral Brick Fits Your Horse Stall, Small Herd, or Wildlife Feeding Setup
At 4 pounds, this brick is practical for situations where a full-size 50-pound block is more than you need. For a single horse or pony in a stall, it provides free-choice trace mineral access at a size that lasts a meaningful amount of time without taking up excessive feeder space or requiring heavy handling.
For small cattle operations or mixed herds, the compact format is easy to position in a stall corner or small feeder. For wildlife supplementation, the brick format sits flat on the ground or on a stump without requiring a holder, which deer and other wildlife can access without the orientation challenges of a hanging block.
The six included micro-minerals address the most common trace mineral gaps in forage-based diets, including zinc for immune and reproductive function, cobalt for rumen health in cattle, and iodine for thyroid support across species.
What to Expect from the North American Salt Trace Mineral Brick in Real Use
Verified buyers have used this brick for horses, ponies, cattle, and wildlife including deer across stall, pasture, and outdoor supplementation settings. Horses and ponies are reported to use it on a self-regulated basis, licking more after physically demanding or hot days when mineral losses through sweat are higher.
The compressed brick construction is noted as tough and slow to dissolve, which makes it economical for single-animal stall use where one brick lasts a meaningful amount of time. For cattle, one buyer reports a noticeable improvement in animal demeanor after introducing the block to their herd.
For deer, one buyer notes the brick-style ground placement is preferred by deer over hanging block styles, with animals discovering and using it within a few days of placement and returning consistently.
Buyers with multiple horses note that this product can be difficult to find in local stores, making online ordering and keeping extras on hand a practical approach for continuous supply.

Frequently Asked Questions
What is the difference between this trace mineral brick and a plain white salt block?
A plain white salt block provides sodium chloride at high purity with minimal additional minerals. This trace mineral brick includes six specific micro-minerals, zinc, manganese, cobalt, copper, iodine, and iron, that are not present in meaningful amounts in plain salt.
These minerals address common dietary gaps in livestock fed primarily on forage and hay, where soil mineral deficiencies can limit what animals absorb from their diet. For animals with confirmed trace mineral deficiencies or for operations where forage quality is variable, a trace mineral block provides more targeted nutritional support than plain salt alone.
Is this block safe for use with both horses and cattle in a shared feeding area?
Yes. The block is listed as suitable for all classes of breed and dairy cattle, pigs, and horses. The copper content in a trace mineral block for general livestock use is typically formulated at levels appropriate for cattle and horses.
If sheep are also present in your operation, confirm the copper level with the manufacturer before allowing shared access, as sheep are sensitive to copper toxicity at levels that are safe for other livestock species.
How do you get deer to start using a mineral brick if they ignore it at first?
Deer typically need a few days to discover and begin using a new mineral source in their territory. Placement near existing travel corridors, feeding areas, or water sources increases the likelihood of early discovery.
Once deer find the block, they return to it consistently. The flat brick format placed on the ground or on a low stump at a height accessible to deer is a practical field approach that does not require a holder or hanging hardware. Leaving it undisturbed after initial placement gives deer time to find it on their own schedule.
