The beneficial effects of pelleted feed on digestibility of nutrients may arise from their influence on intestinal morphology, but the published data on this aspect are so scanty. The only available research (Amerah et al., 2007b) related to this line of research was focused on starter broilers (0-21 d), not growers (22-42 d). Villi and crypts are the functional units of the small intestine, assuming the role of digestion and absorption.
