Farm Animal Feed Supplement


Animal food supplement for Cows, Chickens and other Farm Animals:


At present some 90% of the BioChar produced in Europe is marketed as an animal food supplement where 1% BioChar Powder is mixed in with the animal feed. Studies have shown that when used as a dietary supplement for cows and chickens substantially improves their health, 25% faster increase in the weight of the animals, increases milk production and the laying of quality eggs, reduction or elimination of the need for antibiotics & growth hormones, and as an additive to the animal bedding substrate for chicken coops and cow barns which reduces or eliminates foot infections of the animals due to the BioChar’s absorption of moisture and ammonia which reduces harmful bacterial growth, substantial reduction of odours.

The Cascaded Use of Biochar in Animal Farming

Different to its application to fields, a farmer will notice its effects within a few days. Whether used in feeding, litter or in slurry treatment, a farmer will quickly notice less smell. Used as a feed supplement, the incidence of diarrhea rapidly decreases, feed intake is improved, allergies disappear, and the animals become calmer.  In Germany, researchers conducted a controlled experiment in a dairy that was experiencing a number of common health problems: reduced performance, movement disorder, fertility disorders, inflammation of the urinary bladder, viscous salivas, and diarrhea. Animals were fed different combinations of charcoal, sauerkraut juice or humic acids over periods of 4 to 6 weeks.  Experimenters found that oral application of charcoal (from 200 to 400 g/day), sauerkraut juice and humic acids influenced the antibody levels to C. botulinum, indicating reduced gastrointestinal neurotoxin burden. They found that when the feed supplements were ended, antibody levels increased, indicating that regular feeding of charcoal and other supplements had a tonic effect on cow health.

Studies have shown:

  • Animals gain weight 25% faster with the same rations


  • Significantly reduces methane emissions from the cow (I.e., reduces burping and gas)


  • Reduces antibiotic use


  • Reduces somatic cells while increasing the amount of milk production


  • Prevents mastitis


  • Biochar passes in the feces and then acts as  nutritional fixator that prevents it from seeping into the water


  • Reduces fecal odors and improves the quality of compost

  • Animals are generally healthier and don't get sick, thus saving substantially on veterinary expenses
