“…On the contrary, in the liver of HS-added broilers, reductions of the SOD were found, whereas in the mitochondria of the muscle lower MAD, SOD and higher catalase were found [58]. It was suggested that the difference of SOD activity in serum versus the liver and mitochondria from muscles may be due to their ability to recombine with intermediate free radicals that may lead to partly inactivation of the enzyme [59]. In broilers supplemented with HS and subjected to transportation stress, increased Mechanisms of Action of Humic Substances as Growth Promoters in Animals DOI: http://dx.doi.org/10.5772/intechopen.105956 SOD and GSH-Rx activities in the mitochondria of the liver were observed [60].…”

“…It has been suggested that decreased activity of SOD was connected with the antioxidant properties of HS that decreased the concentration of oxidized products, including superoxide anion [58]. Another possible way to activate the enzymatic activity of the antioxidant system is to increase the concentration of metals in the liver, which are part of the active centers of metal proteins: Zn-catalase, Mn (Cu/ Zn)-superoxide dismutase [59]. The lower fat content in the meat of HS-added broilers and pigs may elicit a higher proportion of antioxidant components and could have an effect on the higher oxidative stability [62].…”

Humus and Humic Substances - Recent Advances

A review of the latest research on the addition of humic substances (HSs) in the drinking water or feed of farm animals including poultry, pigs, dairy cows and calves, goats, and rabbits was carried out. The results reinforces the promoted protective action of HS on the digestive mucosa, their antioxidant properties, immunomodulatory, and anti-inflammatory attributes, the suggested microbial shift to a probiotic-type bacteria in the gut, including antiparasitic and antifungal effects, as well as their influence on the higher efficient of minerals, proteins, and lipids utilization within the body. The outstanding improvements in health, productivity, and meat and milk quality obtained from animals supplemented with HS are common features in the majority of available research. The main benefits in the gastrointestinal tract stem from the formation of protective barriers on the epithelial mucosa due to its colloidal properties and stimulation of mucin production. HS also promotes the development of probiotic microbiota and positive changes in bacterial fermentation patterns, which results in improved intestinal health and integrity. As a result, a cascade of benefits is derived within the body, reinforcing antioxidant protection responses, immunomodulation, and anti-inflammation mechanisms, as well as improving nutrient utilization efficiency. However, the truly molecular mechanisms of action of HS in the intestine and throughout the body remain unknown.

“… Ozturk et al., (2010) evaluated the effects of different doses of HS supplementation, provided through drinking water, on the following parameters: growth performance, characteristics of the carcass and gut, and chemical composition of samples from broilers. Humates administered in food or water promote poultry growth ( Žatko et al., 2014 ). A positive effect of HS was also found in feed conversion of broiler poultry ( Kocabağli et al., 2002 ) and also on meat quality ( Ozturk et al., 2010 ).…”

Multiple factorial analysis of physicochemical and organoleptic properties of breast and thigh meat of broilers fed a diet supplemented with humic substances

et al. 2020

Multiple factor analysis was used for the examination of meat quality of broilers, the diet of which was supplemented with 0.8 and 1.0% addition of humic substances ( HS ). One hundred fifty COBB 500 one-day-old male broilers chicks were randomly divided into 3 different groups: one control and 2 experimental (n = 50), and they were fattened for 35 D. Subsequently, the meat quality was analyzed and defined by physicochemical and sensory quality, supplemented with analysis by instrumental methods. We observed changes in dry matter, fat, water, and protein content in experimental samples of breast and thigh meat ( P < 0.001). In both experimental groups, the concentration of phosphates and pH decreased in breast meat ( P < 0.001) and in thigh meat ( P < 0.05). The smell of experimental chicken breast meat samples after cooking was evaluated by a sensory panel, which scored a higher point score than that of the control group ( P < 0.05). Sensory evaluation of taste indicated a positive response with respect to the perception of meat quality in relation to a greater supplementation of HS in the diet. Thigh meat samples showed a variable extent of water loss after cooking, but lower values of water loss were generally obtained from thigh meat samples of poultry fed with higher HS supplementation, than in chicken breast meat samples. Significant differences in evaluated variables between both experimental groups were not observed. The color of breast meat samples changed, when considering the variables of lightness and redness, with the addition of 1% HS ( P < 0.05). The main advantage of the breast meat of broilers fed a diet supplemented with HS was observed in the final meat quality, which was positively affected by increased protein and decreased fat content. Because of its nutritional composition, it can be considered to be rather a valuable type of meat in human nutrition than ordinarily.

“…Mariam et al [10] found lower levels of Zn in poultry muscle (28.52 ppm). Žatko et al [20] focused in their work on potential antagonistic relationships between iron and manganese, copper and zinc, etc. Antagonistic relationships between zinc and copper lie in their competition during intestinal absorption.…”

“…Humic substances very strongly bind toxic metals in chelate bonds and thus reduce their undesirable effects in the soil and in the digestive tract [18]. The absorptive capacity and chelation of metals by humic substances can reduce the absorption of biologically important elements that are available to the animal [20]. Differentiated effects were shown by humic acids for trace elements, especially for copper and zinc [5].…”

The aim of the study was to assess the effect of humic substances on the changes of copper (Cu) and zinc (Zn) content in the thigh and breast muscle of turkey. For the trial, 20 turkeys (BIG 6) were allocated into two groups (control group and experimental group) of 10 birds. Experimental group was supplemented with 0.5 % Humac Mycotoxi Sorb (HM). The control group received a basal diet without any supplements. The Humac Mycotoxi Sorb was added to turkey feed for 10 weeks. In the breast and thigh muscles, we found a statistically significantly higher (P < 0.001) Cu content after the addition of 0.5% HM to the feed (4.43; 4.18 mg.kg-1 ) compared to the control group of turkeys (2.70;3.35 mg.kg-1). Also, in the breast and thigh muscles, were found a statistically significantly higher (P < 0.05) Zn content after the addition of 0.5% HM to the feed (50.98; 64.42 mg.kg-1 ) compared to the control group of turkeys (44.33; 62.95 mg.kg-1).
