Animal and pet studies
Conclusion: Humic and fulvic acids improve immune function, disease resistance, and growth in animals.
Title: Peat-derived organic humifulvate concentrate (HFC): a novel multimineral dietary supplement
Document Type: Scientific Report
Conclusion: This discovery was made after veterinary doctors observed that animals grazing on or near this deposit were exceptionally healthy, compared to other animals, especially the calves. Studies found that animals consuming the grass growing in these peat deposits experienced accelerated growth and resisted diseases commonly seen in other regions of Hungary and nearby countries. This suggested that the animals had ingested something that had improved their immune function and promoted optimal growth and disease resistance. The peat was believed to enhance the absorption of minerals found in the plants eaten by the livestock. Extensive scientific research has established that this peat deposit contains significant amounts of two predominant humate compounds, humic acid and fulvic acid.

Conclusion: Humic acid at the appropriate dose improves the quality of broiler chickens.
Title: Effects of humic substance supplementation provided through drinking water on performance, carcass characteristics and meat quality of broiler chickens.
Document Type: Peer-Reviewed Journal Article
Conclusion: Humic acid supplementation at a dose of 300 ppm provided through drinking water improved the body
weight gain and feed efficiency without affecting feed intake. Humic acid supplementation at 450 ppm reduced body weight, carcass yield and increased fat deposition in thigh muscle tissue, probably as a direct consequence of reduced feed intake, which negatively affected energy balance and appeared to have a measurable impact on breast and thigh meat lightness, which is one of the main concerns of consumers in the market.

Conclusion: Humic acid has antimicrobial, anti-inflammatory and immunostimulant properties in agricultural animals.
Title: Humic acid substances in livestock
Document Type: Peer-Reviewed Journal Article
Conclusion: There is no doubt that HA has many beneficial effects like antibacterial, antiviral and anti-inflammatory in animals, improves immune system, controls stress and reduces odour in faeces. It also has a positive effect on liver functioning. Ultimately, it reduces mortality and increases growth in poultry. But the level of benefits is now questionable for ruminants because due to its antimicrobial effect it can cause depression of protein synthesis by reducing rumen microorganisms. The supported literature indicating HA as a growth promoter in ruminants seems weak in this aspect and faces doubts. Recent research has ruled out its effect as a goitrogenic substance in rats in case of poultry. So, in relation to growth promoter, its routine use is not so positive but when health risk is higher, it could be beneficial due to disease protection.

Conclusion: Humic substances can improve growth and meat quality in pigs.
Title: Effects of supplemental humic substances on growth, blood characteristics and meat quality in fattening pigs
Document Type: Peer-Reviewed Journal Article
Takeaway: A total of forty-eight finishing pigs were used to determine the effects of humic substances (HS) on growth performance, blood characteristics, and meat quality. The finishing pigs were assigned randomly by weight to three treatments. The dietary treatments included: 1) Control (CON; basal diet), 2) HS1 (basal diet + 5% humic substances) and 3) HS2 (basal diet + 10% humic substances). Results of the whole experimental period showed that addition of 10% HS to the diet, significantly increased average daily gain (ADG) and gain/feed (G:F) (Pb0.05). At the end of the experiment, the relative lymphocyte counts (% of total white blood cells) of pigs fed HS2 diet were higher (Pb0.05) than that of pigs fed CON diet. The Minolta color parameter a⁎ of pigs fed HS2 was similar to that of pigs fed HS1, however, it was higher (Pb0.05) than that of pigs fed CON diet. The inclusion of either 5% or 10% HS significantly decreased backfat thickness (Pb0.05). The marbling score was increased significantly (Pb0.05) when diets were supplemented with HS at a level of 10%. The results of this study suggest that HS might be used as a feed additive in the diet. It could improve growth performance, relative lymphocyte counts and meat quality.

Conclusion: Humates increase milk production and have a calming effect on cows.
Title: Field trials in dairy cattle
Document Type: Scientific Report
Conclusion: The introduction of humate into the diet produced an extra 1.9 pounds of milk per day per cow. Butter fat percentages did not show any changes. With the changes in manure to a fine texture, it can be concluded that the animal was more completely digesting its nutrient, thus generating greater milk production. In addition, humates produced a calming effect on the animals as evidenced by aggressiveness when eating and reduced the effects of heat stress produced by summer temperatures. These factors also increased milk production. Lactation decline curves were dramatically flattened, which will provide additional cumulative total milk production per animal.

Conclusion: Oxyhumate counteracts aflatoxin toxicity in broiler chickens.
Title: In vitro and in vivo evaluation of humic acid as an aflatoxin chelator in broiler chickens
Document Type: Peer-Reviewed Journal Article
Conclusion: The data suggest that oxyhumate may alleviate some of the toxic effects of aflatoxins in growing broiler chickens, and when used in combination with other mycotoxin management practices, may be beneficial in the management of aflatoxin-contaminated poultry feeds.
