The Potential Used of Humic Substance As Natural Organic Additives For Ruminants: A Review

Humate substances (HSs) are raw materials very easy to obtain and naturally occurring organic molecules found in soil due the humification of dead components. Traditionally used as conventional medicine China India fertilizer agriculture. Humic acids widely utilized feed additives could enhance ruminant performance. The effect humic acid on intake depends level supplementation, a source, experimental animals region experimented. also increases average daily gain, sometimes digestibility efficiency goats, cows cattle. Enhancement milk yield, total solids, fat-corrected (FCM), energy but does not influence composition. That supplementation lowers blood cholesterol, excluding eosinophil neutrophil, without affecting haematological value. HSs have anti-bacterial properties affect gut microbiota rumen, such increasing fungi counts pH alteration, bacteria protozoal population is non-consistent. In other trials, been shown reduce process methanogenesis.
