For some administration practices calculating the return on funding is simple. Sadly, figuring out the associated fee vs. good thing about mineral supplementation is just not all the time clear. This is the reason it appears when enter prices go up, the mineral is without doubt one of the issues that may be straightforward to chop out or change with a inexpensive, decrease high quality possibility. The issue is that early indicators of mineral deficiencies may be laborious to establish and sometimes go unnoticed. Finally, in instances of extreme mineral deficiency, producers may see widespread points all through the herd that has us making telephone calls to our veterinarian. However these early and sometimes sub-clinical deficiencies may eat away at efficiency, productiveness, and, sure, profitability. Sub-clinical deficiencies may appear to be a number of extra open cows this yr in comparison with final or needing to deal with a number of extra calves this time round. In fact, there are a number of causes we might see decrease being pregnant charges or increased pull charges from one yr to the following, and we shouldn’t all the time blame it on the mineral. Nevertheless, making certain the herd is protected in opposition to mineral deficiencies is an easy observe in a enterprise the place a lot is outdoors of our management.
Take into consideration the mineral program as a superb insurance coverage coverage. The issue is that lots of our frequent feedstuffs are poor in a number of minerals. The desk under reveals the mineral necessities for a lactating cow and typical mineral concentrations for frequent feedstuffs for choose minerals.
Failure to supply a superb high quality mineral complement leaves the herd prone to growing mineral deficiencies. So, what is an effective high quality mineral complement? My definition is a mineral complement that gives all of the required minerals that must be supplemented in ample quantities to stop mineral deficiencies with out over-supplementation. I like to inform folks with regards to a mineral program, pay for what you want however not for what you do not want.
Minerals that usually require supplementation embody calcium, phosphorus, magnesium, sodium, cobalt, copper, iodine, manganese, selenium, and zinc. Nevertheless, if our mineral program consists of solely a white salt block, we’re solely supplementing sodium and chloride and forgetting the opposite 9 minerals that additionally require supplementation. Even when supplementing with a trace-mineralized block, we nonetheless miss three or extra minerals altogether. Moreover, these merchandise are 95-99% salt, which means the concentrations of the opposite minerals are so low that cattle are nonetheless prone to mineral deficiencies. Some mineral dietary supplements will even embody a supply of iron, which makes the product pink. Iron is one mineral that’s plentiful within the feed and doesn’t require supplementation. It is a prime instance of paying for one thing that’s not wanted.
Selenium deficiencies may be frequent in elements of the US, together with the southeast. Selenium is the one mineral we complement to cattle that the FDA regulates. This is the reason you see one thing like “to not exceed 3 mg of selenium per head per day” on a mineral tag. In instances the place cattle are particularly prone to a mineral deficiency, the supply of the mineral within the complement additionally issues. Cattle are usually not capable of take up and make the most of all sources of a mineral the identical, which is why some sources are extra bioavailable than others. That is particularly vital within the case of selenium as a result of we can’t merely add extra selenium to the complement. Due to this fact, I usually suggest a 50:50 mix of sodium selenite (inorganic supply of selenium) and Selenium yeast (natural supply of selenium) for cattle vulnerable to selenium deficiency.

One thing else {that a} good high quality mineral complement will even present is nutritional vitamins. Cattle being ruminants, can depend on rumen microbes to provide some nutritional vitamins, however Vitamin A and Vitamin E typically require supplementation. Leafy inexperienced forages are a superb supply of each nutritional vitamins, however we all know that cattle typically don’t eat leafy inexperienced forages year-round particularly throughout the winter months or throughout drought. Search for the inclusion of each Vitamin A and E in a superb high quality mineral complement.
Hopefully, by this level, you’re satisfied that supplementing minerals and nutritional vitamins is a needed a part of the diet program, however what’s the precise worth of this observe? The desk under reveals an approximate price for varied mineral supplementation merchandise and the annual price per cow per yr based mostly on track intakes. Though some supplementation choices are cheaper than others, keep in mind that failing to supply a superb high quality mineral can result in misplaced efficiency and productiveness of the herd. So when requested what the precise price of mineral supplementation is, I typically begin fascinated about the worth of a few open cows or the price of elevated morbidity or mortality on the operation. When wanting on the worth of a calf in immediately’s markets, I can shortly make a case for offering a superb high quality mineral complement to the herd.
Store round for the very best worth for his or her mineral program however bear in mind this doesn’t all the time imply the most cost effective possibility. Typically working with a nutritionist to create a customized combine may be extra economical than you may assume. Particularly when you bear in mind my recommendation, pay for what you want however don’t pay for what you do not want. Like different feed substances, shopping for in bulk may lower down on value. Remember that nutritional vitamins lose their exercise over time, so solely purchase a 3–4-month provide of mineral at a time. For smaller producers, take into account partnering with different small producers or native cattlemen’s associations to reap the benefits of bulk reductions on mineral.
Lastly, bear in mind it takes the identical quantity of labor to place out a poor-quality mineral because it does to place out a good-quality mineral. Control mineral consumption to make sure the herd will get essentially the most out of the mineral you present. A 50-lb bag of mineral with a goal consumption of three oz per head per day ought to final 25 cows for about ten days. Cattle have a want to eat salt, so salt is the driving force behind mineral consumption. If cattle eat an excessive amount of mineral, take into account putting a bag of white salt out for a day or two to permit the herd to cost-effectively meet their want for salt after which return to offering the free alternative mineral. If cattle are usually not consuming sufficient mineral, be certain that the mineral feeder is positioned close to the water supply or shaded space the place cattle might be extra prone to go to it.
