Role of Humic Substances in Formation of Safety and Quality of Poultry Meat

Abstract

The purpose of this chapter was to study the influence of humic substances on the formation of the safety and quality of poultry meat. The high abilities of the natural and organic complex of humic acids “Reasil®HumicHealth” (produced in Russia, Saratov) to sorb and desorb five mycotoxins of compound feed (aflatoxin B1, ochratoxin, toxin T-2, zearalenone and fuminisin B1) were experimentally established. The hepatoprotective ability of humic acids was observed in experiments on broilers using rapeseed meal containing an increased amount of secondary plant metabolites that could cause liver damage. It was found out that the inclusion of humic acids in the amount of 1 and 1.5 g per 1 kg of feed to the main diet of broiler chickens has a more stable positive effect, both in terms of slaughter indicators (yield of semieviscerated carcasses and carcasses of complete evisceration), and in the production of the most valuable natural semi-finished products (breast, chicken legs) due to the intensive growth of muscle tissue. A clear improvement in the morpho-biochemical and immunological parameters of blood and micromorphometric characteristics of the organs of the immune system of poultry was noted with the use of different concentrations of humic acid salts. The use of the additive at the rate of 1 and 1.5 g per 1 kg of feed does not negatively affect the sensory indicators of finished culinary products.

Assessment of the inclusion of a feed additive of sodium humate derived from freshwater sapropel in diets for broiler chickens

“…For example, a research study on the inclusion of humus substances in diets for Ross 308 broiler chickens conducted by El Kaya and Tuncer [67] established a higher weight gain and a lower feed conversion ratio in the research group of broiler chickens (1.68), which was 0.18 higher than that found in this study [67]. A research study conducted in Russia on Ross 308 broiler chickens whose diets were supplemented with humic acid 1 g, 1.5 g, and 2 g found that on day 38, the CY was in the range of 70.5%-73.0% [68]. Kocabagli et al [25] established that adding Farmagulator DRY Humate to broiler feed led to a higher carcass weight and yield (73.47%-74.18%) in the groups fed with the humic additive.…”

Humic Substances as a Versatile Intermediary

“…HSs are effective as dietary supplements, as they appear to have only a few side effects (and even those only in highly limited dietary conditions) [58]. HSs designated as the biologically active additives used in medical and veterinary medicine practice are positioned as enterosorbents, immunomodulators [59][60][61] and bioregulators of a new generation [62,63]. The immunomodulatory effect of HA was demonstrated by the course administration of HA isolated by the sodium pyrophosphate method from pine-sphagnum-cotton sedge peat reduced the general anaphylaxis reaction in mice and guinea pigs immunized with ovalbumin and decreased serum content of IgG1 and IgE in mice.…”
