Grazing cattle typically profit from a mineral supplementation program. Easy, proper? Afterall, a well-balanced, cost-effective program solely requires data of vitamin or vitamin precursor, and mineral provide from the forage base, vitamin and mineral ingredient digestibility and availability, and the animals’ vitamin and mineral necessities for his or her present age, stage of manufacturing, and mineral standing (ample vs depleted shops). Prime it off with cattle’s tendency to be finicky and unpredictable in mineral complement consumption and you’ve got a scenario that one among my mates would check with as “a conundrum inflicting nice annoyance and displeasure”.
Chief among the many sources of uncertainty is the dynamic nature of forage vitamin/mineral provide and the cows’ necessities; shifting targets. Clearly, the mineral program doesn’t want to supply exact stability every month, which is nearly unattainable to attain anyway. However, a easy mineral stability train or audit must be useful to a) provide you with some confidence in your present program, or b) reveal an apparent want for a change. A mineral stability excercise includes growing a easy, constant report retaining system to trace forage mineral composition and your cow herds’ common or “regular” mineral consumption sample throughout the identical time of 12 months.
With this info, you need to use a diet analysis program to mission deficiencies and/or excesses. You have to an thought of forage mineral focus, an estimate of forage consumption, a present estimate of common every day mineral complement consumption, and the mineral product’s composition from the label. Most beef cattle diet analysis packages present an estimate of forage consumption and an estimate of every day mineral necessities primarily based on the animals’ weight and stage of manufacturing.
For instance, Determine 1 exhibits the nutritive stability desk for 1,200 pound lactating beef cows grazing lush spring tallgrass prairie forage and consuming 3.3 ounces per day of a industrial mineral complement. You may rapidly view the standing incidators in the fitting column to find out the place main gaps or excesses exist. On this examle, these cows are projected to be about 7 grams per day in need of sodium. Since salt incorporates 40% sodium, this implies that these cows might use a further 15 grams of salt or about 0.5 ounce per day.
There are a number of excesses recognized on this instance. Most mineral stability excercises within the Southern Nice Plains are going to disclose extreme potassium and extreme iron attributable to excessive forage focus of each minerals. The opposite revelation on this stability train the the appreciable extra of selenium. Thus, the conclusion of this train is {that a}) this mineral complement is an effective complement to this forage supply for this time of 12 months and b) one might mix about 10 to fifteen% salt with the mineral to higher match the sodium requirement with consumption and c) the selenium focus within the industrial product could possibly be decreased by about 50% if that have been an choice. It most positively factors out that there isn’t any have to buy mineral product containing a better focus of selenium on this case.

A number of industrial diet firms present providers to conduct these stability excercises and observe up by recommending or manufacturing mineral formulations custom-made to your operation’s wants.
Lately, industrial livestock diet laboratories have integrated mineral composition analytical providers. For instance, our lab at OSU costs $12 per pattern to get macro and micro minerals. Relying in your degree of concern or curiosity, one may get began by conducting a winter feeding and summer time grazing stability. A extra bold strategy could be to gather “hand-plucked” samples from a number of pastures every month. The thought of the hand-plucking technique is to pick out solely vegetation and components of vegetation that you just consider to symbolize what your cattle are at the moment grazing.
Take into account accumulating forage mineral composition and mineral complement consumption information a number of years in a row to get a transparent view of your operations’ patterns over time. Utilizing that precious info, you will get a good suggestion of how effectively your present program or product matches your forage useful resource to fulfill your cow herd’s wants.
