We arescientists who specialize in this area of study, and are trained to provide safe, evidencebaseddietary advice and interventions.Our objective was to examine biological effect of more both Bulgarian and notBulgarian additives and to observe data on their influence on the health of animal, levelof production, reproductive capacity and quality of products from animal origin. Also,we pay attention on the sustainability of the observed results with different type and kindof animals.Herbal additives have aroused much scientific interest over the past few years. Most ofthe studies have been performed on the extracts of herbs and used in the feed of differenttype and categories monogastrics and ruminants. Because of that many herbs showprophylactic and therapeutic effects by regulating the functioning of the internal organsof animals. Bulgarian scientists have recently discovered the potential of a plant extractmixture of seven components in dairy cow nutrition to improve the production andquality of milk and to get better its composition. Substances found in herbs havestimulating and regulating effects on metabolic processes and could reduceenvironmental stress. Feeding herb mixtures seems a more beneficial approach due tocumulative effects that individual herb types can have when fed in combination. Thephysiological effect of the Bulgarian nutritional additive OVOCAP® is based on theseven alkaloids known under the common name CAP (Methyl-vanillyl-nonenamidecapsaicin),carotene and other biologically active substances. While the action ofcarotene is well studied, the action of CAP is not fully cleared. Our experiments withlactating cows showed that CAP has observed effects on: levels of HDL cholesterol weresignificant lowered (P
