Building the System
- Identify the major parts of the digestive system
- Describe the function of each of those parts
- Trace the path- trace the path of an item of food from being ingested as feed to being excreted as fecal material. Describe where different nutrients are digested.
- Create a digestive system with a pre-determined type of system
- Dissect one of the systems!!
How does Nutrition Work in an Animal's Body?
- The MOST important and critical nutrient. Functions to transport, chemical reactions, temperature regulation, and lubrication.
- Water deprivation leads to dehydration, electrolyte imbalance, and eventually death.
- Requirements for quantity vary among species.
- Management problems exist if the water tastes bad...could be high sulfur content, animal does not know how to use the water servicing device or cannot find the water, and stray voltage at the water source.
- Energy source, building block for other nutrients, extra CHOs are stored as fat
- 2 main components of CHOs: 1: crude fiber (cellulose), 2: nitrogen-free extract (soluble sugars and starches)
- Differences between monogastric, hindgut fermenter, and ruminant: all livestock are capable of breaking down the soluable sugars and starches, but ruminants and hindgut fermenters have microorganisms in the rumen or cecum to break down crude fiber into usable products.
- Management problems exist with poor quality feedstuffs and improper ration balancing

- TASK Complete these guided notes.
- Energy is 2.25 times the amount of concentrate grains CHOs
- source of heat, insulation, body protection
- essential fatty acids
- Oils (soybean, corn, and fish oils)
- By-product fats (lard or tallow from livestock rendering and harvest process). These are cheaper energy sources, reduces dust in feed manufacturing and animal feeding, increases feed palatability.
