Herbs exert multiple beneficial effects on livestock condition depending on the type and concentrations of biologically active substances which they contain, including tannins, volatile oils, organic acids, terpenes, flavonoids, alkaloids, glycosides, saponins and phytosterols.
The substances produce antibacterial, antiviral, antiinflammatory and anti-oxidative effects. In addition, they improve appetite, regulate digestive and metabolic processes, prevent diarrhoea, and stimulate the hormone and immune systems.
They may also enhance the functioning of specific body organs such as the liver, pancreas and stomach, increasing their secretory capacity. In addition, they improve the flavour and odour qualities of feed, and step up feed intake.
Herbs can either be used individually or in the form of herbal mixtures, which usually demonstrate higher efficacy. They can also be used in the form of herbal extracts. For example, there are oil and water extracts of plants containing biologically active substances, many of which act as plant-based growth stimulators. These chemical compounds have a stable and beneficial effect on livestock productivity and health status indicators.
