Supplements, Minerals & Salt Feeding Guide
Is a salt block enough for my cows?
No. Salt is what brings cattle to the feeder, but plain salt alone doesn't cover mineral needs, and trace-mineral salt blocks come up short on phosphorus for a lot of grazing. What you want is a complete free-choice mineral; the salt in it does the drawing. A solid beef mineral runs about 2 ounces per head per day with roughly 25% salt, 14–18% calcium, 8% phosphorus, plus zinc, iron, manganese, copper, iodine, cobalt, and selenium.
| Mineral form | Best for | Watch out for |
|---|---|---|
| Loose mineral | Most consistent intake; best for breeding herds | Needs a covered feeder; weather exposure |
| Block | Convenience; easy to put on pasture | Lower, less consistent intake; salt blocks aren't complete |
| Tub | Low labor; steady intake; protein + mineral in one | Cost per head; not right for every class |
What's different about minerals in western Colorado?
Two things. First, selenium: soils formed from shale across much of Colorado can run high in selenium, so don't assume your ground is short on it, and don't stack selenium sources on top of each other blindly. Second, winter: on Intermountain winter range, copper, zinc, selenium, manganese, iodine, and cobalt usually need supplementing, and iron, sulfur, and molybdenum in local forage and water can block the absorption of those trace minerals. Test your forage and water, and where that's happening, ask us about specially coated trace minerals that absorb better.
Loose, block, or tub, which should I choose?
Match the form to how you manage. Loose mineral in a covered feeder gives the most consistent intake and is the standard for breeding herds. Blocks win on convenience for big pasture. Tubs shine when labor is tight, protein plus mineral in one lick. Whatever form you pick: feed by weight, not by the scoop (a scoop's weight changes with the feed), and store mineral cool and dry like any feed.
