Summary In the article the factors that stimulate the growth of the turkey gastrointestinal tract were reviewed. Based on data derived from literature and results of the authors’ own investigation it could be concluded that an effective way to increase the gastrointestinal tract (GIT) development is through the early access of turkey chicks to feed. During the period of growth, morphological development of GIT can be stimulated through appropriate feed additives that support beneficial intestinal microflora. A moderate increase of crude fiber in a concentrate mixture (up to 6%) influences the capacity and structure of the GIT of turkeys to a lesser extent.
