Diatomaceous Earth for Cattle - Uses and benefits


Whether you are a hobby farmer, a rancher or own a cow or two, Diatomaceous Earth (DE) or Fossil Shell Flour as it is also called, can provide you and your stock some great benefits.

Mixing Fine Diatomaceous Earth into your cattle’s feed is a natural way to help prevent fleas and flies from making themselves at home in your cattle’s coat. DE promotes weight gain, helps support their immune and digestion systems and because Diatomaceous Earth is a form of silica it is known to give cattle strong hoofs, healthier and shinier coats. The best results are when the cattle are consistently eating the DE feed mixture.

Diatomaceous Earth is also globally known to reduce internal and external worms and parasites restoring health back to the digestive system all while binding toxins and heavy metals boosting overall health and performance of the cattle. As DE is highly absorbent, if taken internally will reduce the odour of the manure while adding nutrients back into the pastures, boosting water retention and improving feed conversion and pasture quality.

The recommended ratio for mixing Fine Diatomaceous Earth into your cattle’s feed:

We recommend adding 2% of the weight of your cow's feed that they receive either in addition to or instead of grazing. For example, each cow might eat 100 grams dry pellets and 50 grams hay, the DE to be added would be 2% of 150 grams which is 3 grams per portion. We recommend only feed Diatomaceous Earth to calves that are eating solid feeds. Please be careful not to breath in the DE as like most minerals they can be potentially harmful once inhaled.

Mixing Fine Diatomaceous Earth into dry feed or bushel of feed:

Either in a dish, simply mix the measured amount of DE into the portion of dry feed or alternatively you can when you buy a new bag of dry feed calculate 2% of the bags weight and add the correct amount of Diatomaceous Earth to the entire bag. Be sure to shake the bag well to ensure the DE is evenly spread. Repeat this with every new feed bag. By adding Diatomaceous Earth to the bag, you get the added bonus that insects like ants and weevils that can get into the feed are deterred as it is like a natural preservative, which thanks to its amazing moisture absorbing power keeps feed fresher for longer.

Every time you go to feed your cattle be sure to shake the bag as the DE will settle at the bottom of the bag with time. Please be careful not to inhale the Diatomaceous Earth as like most minerals they can be potentially harmful once inhaled. As DE is absorbent it is important that your cattle have access to plenty of water to ensure moisture in the digestive system isn’t affected.

We all know some cows can be quite picky and sceptical about the fine white power that has suddenly appeared in their feed. Don’t fear. Put the portion of feed in a bucket, either add the Diatomaceous Earth according to that potions weight or if you add it into the entire feed bag do not add more DE. Add a little water or molasses to the bucket and stir thoroughly.

Diatomaceous Earth can also be used externally as a drench against the Buffalo Fly. Try using 1 part Fine Grade DE to 1 Part salt. This mixture can also be added to the rubbing roll mixed with oil. Being highly absorbent Diatomaceous Earth sucks up moisture and oil on cattle's coat which will help to deter flies naturally.
