Gergana Yordanova, Radka Nedeva

Abstract: Phytogenic feed supplements are plant products used in animal nutrition in order to improve productivity. This class of feed has recently gained interest, especially since the EU ban on antibiotic feed supplements in 2006. Phytogenics is a fairly new class of feed supplements, with limited research on their effects and application, as well as studies on their botanical origin, processing and composition. The literature analysis indicated that herbal and plant extracts are one of the alternatives for growth promoters as their dosage, type and combinations of application will continue to be a subject of study for nutritional science. This article considers researches on the influence of herbs and herbal extracts, activated charcoal and Spirulina plantesis in combined feeds, the productiveness and health of growing and fattening pigs.
