Literature Support for the Role of Fulvic Acid in Improving Cattle Performance
Effect of adding humate to the ration of dairy cows on yield performance
Takeaway: Fulvic acid-containing humate has positive effects on colostrum quality, milk yield, milk fat ratio, and negative energy balance in dairy cows.
Type of Article: Original research
Summary: The use of humate additives in dairy cows (from prepartum 40th to postpartum 60th day) has no effect on body condition score, body weight, in milk non-fat milk solid, density, protein, lactose, freezing point, somatic cell count, in blood triglycerides, phosphorus, magnesium, albumin, glucose, blood urea nitrogen. With the addition of humate additive to the feed, colostrum specific gravity increased, prepartum and postpartum dry matter intake increased, milk yield and the fat percentage increased, serum non-esterified fatty acid and blood beta-hydroxybutyric acid levels decreased, and postpartum serum calcium level increased. It was concluded that 75 g of humate, which is determined based on dry matter consumption, can be added to the rations of the dairy cows at this dose and has positive effects on colostrum quality, milk yield, milk fat ratio, and negative energy balance.

Effects of a dietary complex of humic and fulvic acids (FeedMAX 15™) on the health and production of feedlot cattle destined for the Australian domestic market
Takeaway: Feeding the humic and fulvic acid complex, FeedMAX 15™, at 0.055 g per kg body weight per day, can increase growth rate and feed conversion efficiency in feedlot cattle.
Type of Article: Original Research
Summary: Cattle were fed either a diet containing a humic and fulvic acid complex (FeedMAX 15™, FeedMAX Industries, Toowoomba, Queensland) or the same diet without the additive. No differences were found between cattle fed FeedMAX 15™ and cattle not fed the additive in entry body weight, exit body weight, dressing percentage, P8 fat depth, meat color, marbling, all diseases, bovine respiratory disease, or mortalities. Cattle fed FeedMAX 15™ reached the market specifications for body weight and fat depth in fewer mean days, had a greater average daily gain, a lower feed conversion ratio, and whiter fat.

The Effect of Humic Mineral Substances from Oxyhumolite on the Coagulation Properties and Mineral Content of the Milk of Holstein-Friesian Cows
Takeaway: Supplementation of humic mineral substances, composed of humic and fulvic acids, in the diet of cows can improve the suitability of milk for cheese production.
Type of Article: Original Research
Summary: One group of cows received humic mineral substances as feed additive, containing 65% humic acids and 5% fulvic acid, for 60 days (100 g cow/day). After 30 days, no significant changes were observed in the chemical composition, somatic cell count (SCC), mineral content (except potassium), or curd texture parameters. However, the coagulation properties improved. The milk from the treatment group after both 30 and 60 days coagulated significantly (15%) faster on average, and the curd was about 36% and 28% firmer after 30 and 60 days, respectively. Further, after 60 days there was an increase in the content of fat, protein, and casein. Calcium and iron content increased as well.

Effects of fulvic acid on production performance of dairy cows in summer
Takeaway: Adding fulvic acid to the basal ration could improve the production performance, stress-countering ability, and economic benefits of dairy cows.
Type of Article: Original Research
Summary: Cows in the control group were only fed on basal ration, while those in the experimental group were fed on basal ration supplemented with fulvic acid at 40 g/cow. This feeding test lasted for 50 days. Adding fulvic acid to the basal ration could maintain the production performance of dairy cows in summer, and enhance anti-stress ability. Daily average milk yields in the control and experimental groups were 28.40 and 31.21 kg/cow, respectively. Economic benefits in the experimental group were increased by 4.47-7.23 PBY/cow. Hence, adding fulvic acid to the basal ration could improve the production performance of dairy cows.

Humic substances isolated from clay soil may improve the ruminal fermentation, milk yield, and fatty acid profile: A Novel approach in dairy cows
Takeaway: Humic substances (humic and fulvic acids) could cause improve nutrient intake, rumen fermentation profile, biochemical parameters, milk yield, and fatty acid profile in dairy cows.
Type of Article: Original Research
Summary: The objective of this study was to examine the effect of clay derived-humic substances (CD-HS), comprising of humic acid and fulvic acid, on nutrient intakes, digestibility coefficients, rumen fermentation, milk yield, and milk components in Holstein-Friesian dairy cows. The CD-HS diets caused a linear increase in blood glucose and a decrease in cholesterol and blood urea nitrogen concentration. The diets did not affect the milk components, but they caused a linear increase on milk yield. Among the total fatty acids of milk, the levels of C18:0 and C24:0 and thrombogenicity index were decreased while increasing the C18:2 isomers (t9t12-C18:2 and C9,C12-C18:2) and polyunsaturated fatty acid contents. It was concluded that the clay derived-humic substances at 5g/kg diet could cause desirable effects on nutrient intake, rumen fermentation profile, biochemical parameters, milk yield, and fatty acid profile.

Influence of fulvic acid in feed additives on protein change and dairy productivity of cows
Takeaway: Fulvic acid containing feed positively affects milk productivity and milk protein content in lactating cows.
Type of Article: Original Research
Summary: The article provides data on the influence of the feed additive “Furor” based on fulvic acid, developed by Esson LLC, on lactating cows. The feed additive “Furor” has a significant effect on milk yield and milk protein content in cows of different periods of lactation. The results of the experiments showed that in the cows of the control group, the decrease in milk yield during the milking period was 4.66 kg of milk, while in the experimental animals it was only 1.59 kg. Milk productivity of cows in mid-lactation showed that in cows of the control group, milk yield over the next 121–180 days of lactation ranged from 33.1 to 31.6 kg, while in animals in the experimental group from 34.7 to 37.3 kg, which is 12.7 kg (9.8%) more. The mass fraction of milk protein in control animals during the study period changed from 2.94 to 3.32%, and in the experimental group – from 3.18 to 3.48. The average milk yield of a cow in the experimental group for 180 days of lactation was 6678 kg of milk, and in the control group – 5908.8 kg, with an average mass fraction of milk protein: 184.95 kg in the control group and 222.38 kg in the experimental group.

Growth performance and meat quality of weaner steers adapted to starter diets containing potassium humate in the feedlot
Takeaway: Humate (humic and fulvic acids) in diets can positively meat quality characteristics of steers.
Type of Article: Original Research (Masters Dissertation)
Summary: In this study, the effects of inclusion of potassium humate (humates contain humic acid and fulvic acid) on performance, meat and carcass quality parameters were examined in weaner steers. The control group was fed basal diet composed of a total mixed ration for growing steers, whereas treatment group was fed basal diet containing potassium humate at a rate of 1.5g/kg feed. Growth performance parameters, including average daily feed intake (ADFI), average daily gain (ADG), and food conversion efficiency (FCE), were measured. Overall, steers fed diet with potassium humate had greater ADFI than the steers in the control group during adaptation period. However, there was no significant difference in the ADG, FI and FCR of steers among the two treatment groups. At the end of the trial there were no significant effects of potassium humate inclusion on growth performance, meat quality parameters and carcass weights compared with control. Inclusion of humate in starter diets of weaner steers significantly improved meat tenderness and caused a greater in meat pH, two of the most important parameters affecting meat quality. Overall, although the results from the study appeared to be inconclusive, it appears that inclusion of humate in diets can positively influence adaptability of weaners to feedlots diets with ultimate desirable effects on meat quality characteristics. Humate inclusion in steer diets can therefore provide an alternative in the production of safe and healthier meat in the feedlot.
