The problem with salt blocks

Many goat producers unwittingly sabotage their mineral supplement program by providing plain-white or yellow salt blocks in addition to loose mineral supplements or mineral blocks. For years, popular wisdom was to provide salt blocks to goats. However, now complete mineral and vitamin supplement products containing salt are specifically designed and available for goats. This article is meant to educate goat producers on proper mineral management and nutrition.



Consumption of mineral supplements is regulated by several different factors, including salt content, hardness, molasses content and “other” factors. Salt is added to a mineral mix not only to meet the salt needs of the goats but also to mask other bad-tasting ingredients and maintain proper consumption. For instance, magnesium oxide has low palatability in livestock. Salt and other ingredients are often added to cover the unpleasant taste and to boost consumption.

Salt is added to a mineral mix to encourage consumption, but it is also added to limit consumption. As an example, think about an order of French fries: doesn’t some added salt make it taste better and encourage you to eat more? What happens if you accidentally spill an open saltshaker on these same French fries? When they have too much salt, you will tend to eat less of them and may even forgo eating them at all. The same principles apply to livestock mineral supplements.

Now you ask, what does this have to do with salt blocks?

When white or yellow salt blocks are provided along with a complete mineral supplement, goats may get all of their salt from the salt blocks and consume none of the complete mineral supplement. Or, more likely, they will consume some of both. While they do get some mineral supplement in this instance, they usually will not receive as much as they need. When you buy a mineral supplement, you will find a set of feeding instructions on the label. The desired consumption rate listed on the label is the rate that is formulated to deliver the full complement of mineral supplement. For example, if the desired consumption of a mineral is one ounce per head per day, the presence of salt blocks may decrease consumption of this mineral to 0.5 ounces per head per day. Let’s also say that this mineral is designed to deliver 100% of the daily recommended allowances for trace minerals. In this case, the goats would have only half of their trace mineral needs met by this feeding scenario and, in time, could develop mineral deficiencies, especially in selenium.

In all cases, you must read and follow the label directions for any livestock supplement. Never provide additional salt sources to goats receiving free-choice complete mineral supplements unless the product label specifically instructs you to do so. In rare instances, some supplements do recommend that you provide additional salt.

The cost of a good complete mineral supplement represents a significant cost in goat production. You invest this money with the knowledge that your investment will pay off in improved herd health and increased productivity. Adding salt blocks that decrease the effectiveness of your complete mineral supplement significantly reduces the value of your investment.
