Abstract: In recent years, there has been a surge in antibiotic resistance in both humans and animals, as well as increased public concern over medication residues in animal products. As a result, the use of antibiotics as growth promoters in chicken has been banned in the European Union, and consumer pressure is likely to lead to their removal in other countries. More recently, the United States of America adopted the same restriction in 2017. Different alternatives to antibiotics have been proposed as a measure to eliminate pathogens or to improve growth and feed conversion in poultry, such as probiotics, enzymes, bacteriophages and antimicrobial peptides, herbal compounds and organic acids. These substances exert their effects on the gastrointestinal biota and digestion processes, directly or indirectly. Humic substances (HS) in animal applications have shown improved live-weight, growth rates and feed intakes by improving immune functions and gut health. In poultry nutrition as an alternative to growth-promoting has been proven with promising results on the growth and health of birds. Additional research suggests that HS can increase gut integrity and performance when combined with good nutrition, management, and biosecurity policies. Therefore, recent results of HS extracted from vermicompost in poultry will be described in this chapter.

TL;DR: In this paper , the effect of humic substances (HS) on the morphometry of villi in broilers raised under stable digestive conditions and following abrupt dietary changes was studied. But none of these theories have been demonstrated.

The contentious nature of soil organic matter
Johannes Lehmann,Markus Kleber +1 more
TL;DR: It is argued that the available evidence does not support the formation of large-molecular-size and persistent ‘humic substances’ in soils, and instead soil organic matter is a continuum of progressively decomposing organic compounds.

Composting of animal manures and chemical criteria for compost maturity assessment. A review
TL;DR: The basic concepts of the composting process and how manure characteristics can influence its performance are explained and a summary of those factors such as nitrogen losses, organic matter humification and compost maturity which affect the quality of composts produced by manure composting is presented.

The supramolecular structure of humic substances: A novel understanding of humus chemistry and implications in soil science
TL;DR: A review of the scientific understanding of the molecular structure of humic substances can be found in this paper, where a large body of evidence suggests that the traditional view that humic compounds are polymers in soil is not substantiated by any direct evidence but only assumed on the basis of laboratory experiments with model molecules and unwarranted results by incorrectly applying either analytical procedures or mathematical treatments developed for purified and undisputed biopolymers.

An update on alternatives to antimicrobial growth promoters for broilers
TL;DR: A number of non-therapeutic alternatives, including enzymes, (in)organic acids, probiotics, prebiotics, etheric oils and immunostimulants are described in this review.
Antioxidant Properties of Humic Substances
TL;DR: The results suggest that HS contain a wide variety of moieties that are oxidized at different potentials and that, upon oxidation, release protons and undergo irreversible follow-up reactions.
