Research on herbs and combination of herbs and their concentrations instead of antibiotics would have practical application in pig breeding for successful health management in organic farms. The aim of this study was to investigate prophylactic and therapeutic effect of herbs on performance and health of suckling piglets. One scientific experiment was carried out in Experimental station of Agricultural institute – Shumen with total 154 pigs from 16 litters, originated from Danube white breed, spread as follows: first treatment – Control group (CG) - 8 sows and 77 piglets and second treatment - trial group with supplement of Origanum heracleoticum (OG) – 8 sows and 77 piglets. Pigs from CG have been raised according to conventional methods and treated in cases of diarhoea with antibiotics. Sows of OG received from day 7 before birth till the end of the trial at 35 day after birth diet supplemented with 5 g to kg feed of Origanum heracleoticum as well as their offspring. When cases of diarhoea occurred, treatment was made by concentrate of Origanum heracleoticum and Potentilla Erecta Raus, herb with anti-inflammatory and anti-diarhoea action, due to high content of tannins. Live weight at birth, 21 day, 35 day (at weaning), average daily feed intake (ADFI), average daily gain (ADG), health condition of sows and piglets (score of faeces) and number of Escherihia coli colonies at weaning were registered. Results showed statistically significant differences between groups in ADG in the period 21-35 day (P
