The industrial maintenance of livestock and poultry on a large scale in an intensive manner has increased the possibility of diseases, which reduces the occurrence of these diseases helps to increase growth and improves production traits. Today, the use of growth-promoting antibiotics has been limited due to the possibility of bacterial resistance and also transmission through manufactured products to consumers. Medicinal plants with antimicrobial effects and reduced serum lipids have been proposed as suitable alternatives for antibiotics. The origin of many medicines are herbal plants because due to the lipophilic nature of the effective oils found in some medicinal plants, these compounds can completely disrupt the membrane structure of bacteria, especially Gram-negative bacteria, and even some effective oils in essential oils have Irritation of the digestive system, increasing the production of digestive enzymes, improving the use of digestive products and the body's immune response. The most important biological activity of medicinal plants is related to antioxidant and antibacterial activities, related to their biologically active molecules such as carvacrol, thymol, cineol, allicin, capsaicin, piperine, etc. The property of stopping the reproduction of the disease agent or the lethality of the disease agent is a common point between chemical drugs and medicinal plants, but creating a protective layer on the intestine to prevent the penetration and growth of the coccidiosis agent in the intestines and stimulating the body's immune system against the disease agent is a unique feature.
