Prohibition of application of antibiotic growth promoters in broiler chicken diets has resulted in increased use of herbs as natural additives in broiler feeds, herbs that can affect such parameters as growth performance, immune response, or treatment of certain diseases, Aloe vera as a natural additive to broiler diets, Aloe vera can improve immune response and growth performance in broilers. In addition, Aloe vera is an excellent alternative for antibiotic growth promoters and anticoccidial drug, animal feeds, there are concerns about the presence of antibiotic in animal products and probable bacterial resistance in animals and human body, more studies now look for alternatives for antibiotics in order to eliminate their impact on animals, natural feed additives for animals and poultry, supplements for improving growth performance, improving immunity response, improving intestinal microflora, and controlling particular diseases, analyzed by researchers is the polysaccharide acemannan, Balance of intestinal microflora in broilers is an important factor contributing to improved growth performance and immune response, and anti-bacterial compounds, impacts of Aloe vera on intestinal microflora in broilers, Aloe vera to its fumaric acid content, important factor in improving homogeneity, long life, and growth performance of birds, researchers on improving immune response, mannose receptors in macrophages, Acemannan contained in Aloe vera gel is a ? (1-4)-linked acetylated mannan, Experiments on chickens suggest promoted macrophage activities in broilers caused by the acemannan contained in Aloe vera, Aloe vera effects on humoral immunity of broilers, Aloe vera, as an additive to broiler chicken feed, has great potentials for improving intestinal health, immune system response, and growth performance, Aloe vera added to broiler feeds depend on several factors: form of use (powder, gel, extract (ethanolic or aqueous), polysaccharide extracted from gel), dosage, genetics of broilers, ingredients of diet, and farm management
