Among a significant number of biologically active substances capable of increasing the level of nonspecific resistance, our attention was drawn to humic substances that positively affect the physiological and biochemical status of animals. The effect of biologically active substances, which includes potassium humate, is evaluated, which makes it possible to activate the metabolic processes in the animal's body, to promote the transformation of feed nutrients into available forms, and thereby play an essential role in solving one of the primary tasks – the rational use of feed. The effect of potassium humate in a dose of 4 g of the drug per 1 cow during the dry period per day was determined, contributing to an increase in the live weight of newborn calves by 22.4 %. Later, the calves of the experimental group exceeded the control group: after the 1st month of growing – by 28%, and after the 2nd month – by 23.9 %. Due to the feeding of potassium humate, the number of fertilized cows increased by 22 % compared to the control. The pattern of enrichment of rations with potassium humate is characterized, which allows an increase in cows' average daily milk yield by 20 % with a simultaneous reduction in protein consumption by 14.2 %, feed units by 13.9 %, and exchangeable energy by 13.5 %. The use of potassium humate in the diets of dry cows does not cause significant changes in protein metabolism and the levels of AST, ALT, and glucose, which is evidence of normal liver function, but it helps. Reduced cholesterol synthesis in cows that consumed potassium humate – up to 3.88 mmol/l against 4.72 in the control. The explanation of this phenomenon will require further research. It was possible to increase the overall efficiency of nutrition by 10–20 % during the experiment, thanks to the inclusion of potassium humate in the feed mixtures of nettles and dairy cows. The adaptogenic effect of humic preparations has also been proven, including in stressful situations.

The objective of this study was to examine the effect of humic acid (HA) supplementation on the rumen fermentation and protozoal community in the rumen. For this purpose, four ruminally cannulated Simmental cows were randomly assigned in a replicated 4 × 4 Latin square design experiment to study the effect of HA dietary supplementation on feed utilization, rumen fermentation, and protozoal community for 84 days. The basal diet (BD) was composed of meadow hay (68.2% of dry matter [DM]), maize silage (17% of DM), and granulated feed mixture (14.9% of DM). There were four treatments, including the BD without additives (control diet, H0), the BD supplemented with 50 g HA/cow/day (H50 treatment), the BD supplemented with 100 g HA/cow/day (H100 treatment), and the BD supplemented with 200 g HA/cow/day (H200 treatment). HA supplementation did not affect the total or individual volatile fatty acid concentrations, the total protozoa, or the ruminal pH. However, HA at the dosage of 50 g/cow/day increased the NH3-N concentration and fecal nitrogen compared to the control (p < 0.001). HA supplementation also significantly impacted the abundance of individual protozoal genera in the rumen. The results of this study suggest that HA has potential in ruminants as a natural feed additive and may play a role in nitrogen metabolism and stabilizing the protozoal community without adverse effects on rumen fermentation.
