Secondary plant material is the rational alternative in veterinary medicine

Antimicrobial resistance to medicinal products for human use and veterinary medicinal products is a growing health problem in the Union and worldwide. Due to the complexity of the problem, its cross-border dimension and the high economic burden, its impact goes beyond its severe consequences for human and animal health and has become a global public health concern that affects the whole of society and requires urgent. Environmental incidents that are observed following the administration of a veterinary medicinal product to an animal should also be reported as suspected adverse events. Such incidents may consist, for example, in a significant increase of soil contamination by a substance to levels considered harmful for the environment or in high concentrations of veterinary medicinal products in drinking water produced from surface water [1]. Consequently, the issue is the development of medicinal feeds containing active active substances of biological origin. Oregano, thyme, garlic, horseradish, chili pepper, peppermint, cinnamon, anise are used as natural growth stimulants for farm animals [2]. The technology of feed manufactoring involves the addition of antioxidants, preservatives, biostimulants and components intended for the treatment and prevention of animal diseases in their composition. Nowadays, investigations on secondary metabolites recovery from plant and by-products are increasing due to consumer’s awareness of its health and nutraceutical benefits. Currently, many studies have focused on agricultural and industrial wastes in the search for natural antioxidants. One of the approaches is to use as raw material components of the feedstock of plant raw materials [3, 4].
