After lambs become two weeks old they will begin to nibble for salt. If you do not allow them the salt they will eat any loose dirt. This may kill a few in any case. Should your pasture contain much alkali, or soil containing small quantities of arsenic matter, you are likely to lose quite a number of the lambs about the time they begin eating, as they invariably nibble for a salt substance first. If convenient, feed the loose salt in troughs only; otherwise use block salt. Allow about three ounces per ewe each week, or roughly speaking twenty pounds of salt for each one hundred ewes and their lambs per week. They will require this amount only where they are on very soft, green feed. Upon the range, where there is considerable natural salt feed, or the water is strongly alkalized, they will not consume that amount. Where they are given salt at regular intervals there is no danger of over-feeding. Salt is good for the wool; it makes good healthy lambs.
