The use of plant extracts with the objective of improving production results and the quality of food articles of animal origin is an area which is acquiring increasing scientific importance. Numerous investigations carried out so far on ruminants and other species of domestic animals have been aimed at examining specific bioactive matter of plants. The results of these investigations have demonstrated a positive influence on the production results. A large number of data indicate that plant extracts added to animal feed contribute to increasing overall productivity. Furthermore, plant extracts as additives in animal feed have a positive effect also on the health condition of the animals. A large number of plants have characteristics which potentially improve consumption, digestibility and conversion of food, and also growth. Examinations have been performed of the effects of different plant extracts on food consumption, wool growth, growth and composition of the trunk, milk production, reproductive parameters, agents for wool shearing, preventing bloat, methane production, as well as the influence of plants on curbing nematode infestations of ruminants. This work presents a review of scientific investigations of different plant species and their effects on the production characteristics of ruminants. .
