Humic preparations belong to natural growth regulators. Humic preparations eliminate the negative effects of factors unfavorable for the development of plants, normalize the processes of intracellular metabolism. Humic substances are adsorbed on the cell wall of the animal organism, increasing the elasticity of its membrane and increasing the surface of the cell, this leads to an increase in the amount of oxygen and metabolism entering it. With the introduction of humic substances in the diet of cattle, the average daily increase in live weight increases by 14.4%. When used as an additive in chickens feed, the average daily increase increases by 11.85%, the weight of the heart, liver, spleen, and gall bladder up to 20.7%. The average daily gain in sucking piglets is increased by 8.3%. A line with a vacuum evaporator was developed to increase the concentration of humic suspension. The installation consists of a heating chamber, a steam pipeline, a steam condenser, a condensate tank, a water-air ejector, a cooler, a water tank, a centrifugal pump, a hot water supply pipe to the heating jacket, a water drain pipe from the shirt, a working water pipe, a pressure gauge, vacuum gauges, a thermometer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
