“…In EG3, which was given an extruded granulate containing 0.4mL of balsamic poplar buds extract and 100% activated charcoal at a dose of 3.0g/head per day, milk productivity increased by 25% or 231.2g at the end of the experiment. Recently, Burchacka et al (2019) studied the role of activated coal as a feed additive. The carbon porous structure allows it to absorb substrates, products and catalysts from the environment, thus changing the bio-catalysis processes in the gastrointestinal tract.…”

Goats are important livestock species for meat and milk production. Meeting goat nutritional requirements is essential in maintaining goat health and the quality of derived food products. Dietary supplementation with certain bioactive compounds can improve the quality of diet and help to create a productive and economical nutrition program. The aim of this study was to evaluate the effect of several feed additives on the milk productivity of Saanen goats. According to the method of pairs of analogues, 72 dairy goats were distributed into four groups (18 goats/group): the control (CG) – the conventional diet with no additives: the experimental groups 1 (EG1) - the diet with 10% extract of balsamic poplar buds; the experimental groups 2 (EG2) – the diet with vegetable protein hydrolysate; the experimental groups 3 (EG3) – the diet with 10% extract of balsamic poplar buds with activated charcoal (EG3). Supplementation of feed with balsamic poplar buds increased goat's milk productivity by 34.2% without compromising milk quality, which was evaluated by the amount of milk and contents of milk fat and protein. Supplementation of feed with balsamic poplar bud extract and activated carbon contributed to an increase in milk yield by 25%. Such, using phytobiotic feed additives is a promising method in animal husbandry.

“…The latter imparts a strong negative charge to the surface of Gram-negative bacteria cells. It was previously reported that the elemental content and electron microscopy (EM) analysis of active carbons indicated that the oxygen content is important in the adsorption of Gram-positive and -negative bacteria over electrostatic interactions [ 22 ]. In the tested carbon material, PAC, the oxygen content was significant, as it amounted to 5%.…”

“…Adsorption tests of Gram-negative bacteria such as Escherichia coli on commercially available ACs have shown that the sorption capacity of bacteria increased with increasing the hydrophobicity and volume of macropores in the ACs [ 21 ]. Moreover, activated carbons that contain more oxygen species on their surface promote a higher level of adsorption of Gram-negative and Gram-positive bacteria and improve the weight and feed conversion ratios of broiler chickens when added to their feed [ 22 ]. The ability of ACs to adsorb many toxins, such as toxic metal ions, bilirubin, and protein-bound uremic toxins, has been demonstrated in scientific papers [ 23 , 24 , 25 ].…”

Antibiotic overuse and mass production have led to a global problem with the treatment of antibacterial infections. Thus, any possibility to limit the number of antibacterial drugs used will contribute to a decrease in the development of pathogenic bacterial resistance. In this study, the enhanced bacterial growth reduction of pharmaceutical activated carbon (PAC) material with adsorbed antimicrobial agents compared to the activity of pure antibacterial drugs was investigated. Sulfamethoxazole (SMZ) at a concentration of 1.1 mg/mL retained the growth of S. aureus and E. coli at 20.5% and 26.5%, respectively, whereas SMZ adsorbed on PAC increased the reduction of the tested bacteria in the range of 47–72%. The use of PAC with adsorbed gentamycin (G) over 24 h improved the effectiveness of E. coli growth reduction by 50% compared to the application of pure antibiotic (3.6 µg/mL). The increased reduction of S. aureus growth by 6% using G with PAC for a 24-h incubation time compared to the use of pure antibiotics at a concentration of 3.6 µg/mL was observed. The results provide proof-of-principle that the new approach of activated carbon with adsorbed antimicrobial agents could yield an attractive background with potential as a new starting material for S. aureus and E. coli pathogen elimination, e.g., in wound-healing treatment in the future.

“…HA isolated from peat, brown coal, soil, composts have high biological activity, in comparison with HA of the soil itself. This is explained by the fact that the functional groups in it, which determine the reactivity, solubility, and biological activity, are blocked by metal cations [7][8][9].…”

This study examined the effect of feed additives based on brown coal on the productivity indicators of laying hens. The Relict A® organo-mineral feed additive for livestock and poultry is a multi-component, gummatized product with a wide range of biological activity, accelerating the growth and development of the animal. Relict A® is an environmentally friendly supplement that does not contain hormones or synthetic compounds. The control group was fed complete feed without additives. The second, third and fourth groups were fed feed containing 0.04%, 0.06% and 0.10% of the studied additives, respectively. The amount of feed for each group of laying hens was strictly normalized in accordance with their age, according to the recommendations for this cross. The use of the Relict A® feed additive in the laying hens’ rations led to an increase in the average number of eggs per laying hen, a decrease in the cost of feed for producing 1 dozen eggs, and a reduction in the time when the poultry reached the peak egg laying intensity. Feeding the additive to laying hens reduced the cost of producing 1 dozen eggs in the experimental groups, and also increased the profitability of chicken eggs in comparison with the control. The best dose was to use 0.06% of Relict A® by weight of the feed. A 26.6% increase in laying hen egg production was found. Keywords: feed additives, laying hens, egg productivity, brown coal
