ABSTRACT
An in vitro investigation using the rumen simulation technique (Rusitec) was carried out to
investigate the effects of dietary supplementation of plant preparations with known antimicrobial
properties on ruminal fermentation. The following preparations were added to a mixed forage-concentrate
(1:1) diet (g/kg feed dry matter): Hypericum perforatum flowers (2.86), essential oils
of Pinus mugo (0.57) and a plant extract mixture (5.71) containing these two plant preparations
in proportions of 0.5 and 0.1 of total, respectively. None of the treatments significantly affected
ruminal fermentation traits. A trend towards enhanced bacterial population and daily volatile fatty
acid formation was observed with the mixture. Ruminal nitrogen turnover showed a positive trend
with Hypericum-only supplementation without affecting protozoal population. According to the
present results, it is possible to use these plant extracts as alternatives to antibiotics for the lower gut
in the dosages tested without adversely affecting the ruminal ecosystem.
