Abstract
Modern intensive poultry production has achieved phenomenal gains in the efficient and economical production of high quality and safe chicken meat, eggs and poultry bio-products (George, 1996). At the same time as making gains in production and efficiency, the industry had to maximize the health and well-being of the birds and minimize the impact of the industry on the environment. The use of feed additives has been an important part of achieving this success. Many additives have been a normal part of diets for animals and humans. It is only recently that we have come to recognize and understand their importance in achieving high production and efficiency, maintaining health and wellbeing, improving product quality.(Windisch et al., 2008) However, the feed additives have negative impacts on the consumers due to their residues which mostly remain in the broiler products. Thus, it is important to explore the potential of natural feed additives to replace the chemical ones.(Scott,2004) Probiotic and medicinal plants as natural feed additives are recently used in poultry diet to enhance the performance and the immune response of birds. One of the natural feed additives is ginger. Ginger contains bioactive substance such as oleoresin and ginger which give effect to optimize the body organ. Ginger also contains vitamins and minerals as the peculiar plant. Ginger extracts function as the anti inflammation and anti bacterial. Ginger is one of natural plants which can be used as phytobiotic to improve broiler's performance. The major component of ginger is Zingiberen and Zingerol that can stimulate the digestive systems by controlling the digestive pH and the activity of digestive enzyme and the microbial activity. Ginger extracts could immune the gastric and improve poultry appetite. (Achyad et al., 2000) Studies show that the ginger spice has two types of digestive enzymes; one is protease enzyme that is used to break apart the protein and lipase enzyme that is used to break apart the fat. Both enzymes improve nutrients digestion and absorption by animals. Ginger is also as bacteria static that reduce pathogenic microorganisms in the digestive tracts. The gingerol also protect the liver on it activity, especially on hold the toxic of carbon tetrachloride. The ginger works as vaccination by stimulate an organ of bursafebrisius to make an antibody of viral attack such as ND. Ginger as a natural material is good as additive because it has no residual that threat the body organ and safe for the consumer's health. (Peter et al., 1999)
