Most ranchers will put out salt licks when there is little chance of their herd getting enough elements from the earth. Sometimes there is enough natural occurring salts that are close to the surface for the cattle, but the winter would see even those areas covered with snow.
A trace-mineral sheep salt lick lacks copper. A trace-mineral lick for cattle (and horses) includes copper.
Cattle usually will lick themselves to scratch an itch or remove flies off of their bodies. Another term for lick could be the salt lick, this is a block of salt or minerals that the cattle will lick, it just gives them extra nutrients.
This question has already been answered in two separate questions. See them in the Related Questions section below.
No
Blue blocks contain NaCl (table salt), Cobalt and Iodine. Red blocks contain Salt, Iron and Iodine. Brown blocks contain Salt, Cobalt, Iodine, Iron, Zinc, Copper, Manganese, Molybdenum, Potassium and Magnesium (guessing on the last two minerals) Black blocks contain everything that the brown blocks do, plus Selenium.
Deer are know to lick blocks of salt.
Yes, there's nothing that says that they cannot. Most, if not all, salt blocks are made for both cattle and horses, not just for one particular livestock species.
There really is no such salt block or mineral mix. You can check with your veterinarian or those companies that make livestock salt blocks but it's highly likely you will not find such an ingredient in salt licks for cattle.
There is no difference, really. The salt licks that are given to cattle are the same ones that are given to horses. Horses may get a smaller salt block, but other than that, the mineral content is all the same.
Goats should have salt blocks specifically made for them. However, if you cannot get such blocks, there isn't really anything wrong with giving them a mineral block intended for cattle.
No such ingredient is found in salt blocks for cattle. It is merely a myth or rumor that has been passed along from one drug addict to another in their attempt to gain different ingredients to make methamphetamine.
No. All mineral blocks have enough salt in them to sustain cattle alone without having to have an additional salt block set out. Because mineral blocks are called "trace mineral" blocks, this means that 95 to 98% of the block is comprised of salt, while the other 5 to 2%, respectively, is composed of mineral.
