We recently found this study showing good improvement for animal feed with Shungite added to it. It can open up new areas for Shungite.
Growing young chickens under conditions of intensive keeping technology can lead to a decrease in nonspecific resistance, the manifestation of immunodeficiencies and increased susceptibility of the bird to adverse environmental factors and various opportunistic microorganisms. The presence of mycotoxins in feed is one of the main feed stresses. At the same time, stresses associated with vaccinations are added in the future, and, of course, heat stresses play a special role in the summer months. The purpose of the work is to study the influence of the domestic natural adaptogen from the mineral shungite on productivity indicators and on the composition of the intestinal microbiome in young chickens of egg breeds.
