Explore the digestive systems of monogastric animals (e.g., horses, pigs and chickens) and ruminants (e.g., cattle, sheep, goats). Watch as a professor of animal science uses models, computer-generated graphics, laproscopic images taken within the system of a live animal and digestive tracks removed from slaughtered animals to teach about prehension, mastication, simple digestion and rumination. Viewers explore the entire digestive system of a pig, chicken and steer to identify organs and to understand the tissue structures and functions. The instructor dissects organs to expose contents and secretions aiding digestion. A supplement is included.
