    Poultry industry are facing many challenges and osbtacles especially on the supply of feed ingredients, medicines, feed supplements and additives. The high price of protein source-feed ingredients has encouraged nutritionists to explore and utilize alternative protein source-feed ingredients for poultry. This review provides an overview of their nutritional and bioactive contents and the use of microalgae, Chlorella vulgaris and Spirulina platensis in poultry feed based on recent literature studies and their potential development and utilization in Indonesia. The microalgae Chlorella vulgaris dan Spirulina platensis have very high protein content that are potential as a protein source in poultry rations. In addition, Chlorella vulgaris and Spirulina platensis also contain several bioactive compounds that can be used as alternatives to antibiotics growth promoter and synthetic antioxidants for poultry. Indonesia has a great potential for the production of Chlorella vulgaris and Spirulina platensis, however massive cultivation and economies of scale have not yet been carried out. Such conditions make Chlorella vulgaris and Spirulina platensis less profitable as protein sources, but more likely as growth-promoting additives or antioxidants for poultry in Indonesia

    The Potentials of Two Underutilized Acidic Fruits (Averrhoa bilimbi L. and Phyllanthus acidus L.) as Phytobiotics for Broiler Chickens

                Phytobiotics have attracted considerable interest as the substitutes for subtherapeutic antibiotics in broiler production. Among the phytobiotics, Averrhoa bilimbi L. and Phyllanthus acidus L. fruits seem to have potential to be developed. Both underutilized acidic fruits contain several bioactive components that may serve as antimicrobial agents, antioxidants, immunomodulators and acidifier, which are beneficial for broiler performance and health. The bioactive components responsible for as well as the mechanisms through which the components exert the phytobiotic activities are highlighted in the present review. The current application of A. bilimbi and P. acidus fruits in broiler production is also presented. Overall, although A. bilimbi and P. acidus fruits show phytobiotic properties, they are still less utilized by the farmers to improve the growth and health performance of broiler chicken
