Trials with Fulvic/Humic in Animals

Dairy Cows

In a test herd of cows, cases of mastitis dropped from 3 – 4 cases per day to 4 cases in one month. (See 1 below) In another herd of cattle, volatile ammonia in the animal waste decreased by 64%. There was a reduction in odour and an improvement in the NP ratio in the waste. Examination of the waste showed a more complete digestion of food. The urine of those animals on humates was clear and odourless while the control herd had strong smelling amber urine.

In Texas, a herd of 500 cows trialled on humates over 28 days. The milk production, blood and waste of the herd was examined before, during and after the introduction of humates.  The cows produced 1.9 lbs of extra milk daily per animal but their daily feed consumption dropped from 38 lbs per day to 36 lbs. The cows were digesting their feed more completely resulting in both a smaller need for feed and a higher milk yield. It was also noticed that the cows on the humates were far less aggressive when feeding, calmly eating their rations while the control herd ate greedily and aggressively. A reduction in heat stress was also observed in the cows on humates. The lactation decline curves were flattened, meaning that the farmer was gaining a longer milking period from each cow. The manure of the test herd had fewer odours and less ammonia.

In another trial in Texas, a farmer mixed humates into the feed of three calves and one cow. After 60 days, the colouration and health of all four animals was excellent and the calves had an above average weight gain. An added bonus for the farmer was that the cow became pregnant during the trial; he had been trying without success to get her pregnant for three years.


In cutting horses and racing quarter horses, healing times for ankle injuries have been reduced by 1 – 2 weeks and the horses have performed better in timing trials.

In Texas, a horse with severe hoof degeneration was put on humates and the hoof grow out amazed the farrier. The horse was able to be shod and back in the show ring in 4 – 5 months. Some horse owners have reported their once unmanageable horses becoming beautifully behaved at shows once they were put on humates. Note: All show animals have all been observed to be calmer and less affected by outside stimulus in the show ring.


Substitute for prophylactic anti-biotic, produces a substantial increase in the bioavailability of nutrients and appetite, reduces mortality, increases live weight, increases resistance to diseases and environmental stress, reduces smell of faeces and urine/body odour, reduces scouring and produces leaner meat.

Humic acid showed a higher quality in chicken meat. A higher affinity for AFB1 (Aflatoxin B1) and was effective in diminishing the adverse effects caused by aflatoxins on the body weight of Broilers, Also showed increased in Cal levels and body weight gains, with protective effects against liver damage and stomach and heart enlargement. See 3, 4, and 5 below

De-Tox advantages: Humates were administered to a group of test mice for 10 days. Then they and a control group were given toxic doses of strychnine. All of the control mice died while all of the mice on humates survived.
