Overview

This lesson can be used to prepare for a visit, or as a stand-alone lesson in the classroom.  Students will explore Mrs. Sandburg's prize-winning dairy goats with a focus on learning about the properties of goat's milk, how it's different from cow's milk and how goat's digest differently than humans.

Objective(s)

Learning Targets

  • I can analyze and discuss information presented on a website.
  • I can use a Venn diagram to compare and contrast human and goat digestive systems.

A Comparison Between the Human and Ruminant Digestive Systemby Julie Eden.

Differences

Ruminants:

Humans:

·       Mouth is taken to food.  Specialized tongue and lip for grasping and tearing.

·       Food is taken to mouth by hands, utensils, etc...

·       Well-developed molars and premolars for grinding, movement is "lateral".   A gap between premolars and molars allows the tongue to manipulate the food into small amounts prior to swallowing.

·       Incisors and canine produce shearing action, used for cutting food, premolars and molars for grinding and crushing.  Upper and lower teeth movement is "vertical".   

·       Protein needs supplied by rumen bacteria.

·       Protein is a dietary requirement and is provided by the intake of various foods.

Need variety of foods to obtain various other nutrients.

·       One set of teeth for life, teeth wear flat with age.   In most ruminants upper teeth replaced by "Dental Pad".

·       Two sets of teeth (childhood and adult).  Adult tooth loss through decay and improper nutrition - replaced by dentures (false teeth).

·       Regurgitation of cud for chewing at rest

 

·       Vomiting more common in carnivores and omnivores. Forceful ejection of gastric contents from the mouth.

·       Complex digestive system (Four Stomachs).

·       Digestive System (one stomach).   Ill health, weather changes, irritability and stress, may have an effect on digestive processes.

·       Herbivores – do not eat meat.

·       Omnivores – eat meat and plants.



Similarities:

  • We require food, water, and oxygen to sustain life.
  • We require similar nutrients.
  • We produce similar waste products.
