Part of Course: Animal Science Model
Unit Overview / Details
This unit contains lessons about nutrient flow, balanced rations, digestive processes and the influence of physiology on animal nutrition.
- 15 Hours
Content / Concepts
- Flow of nutrients from the soil, through the animal, and back to the soil
- Proper balanced rations for a variety of production stages in ruminants and monogastrics
- Digestive processes of ruminant, monogastric, avian, and equine digestive systems
- How animal nutrition is affected by the digestive, endocrine, and circulatory systems
Lessons in this Unit
This lesson would be conducted after instruction has occurred on the digestive tract of a ruminant, prior knowledge of vocabulary is assumed. This lesson is designed to study the physiology of the ruminant stomach and the type of digestion that occurs in each compartment. Students will observe the internal tissue of each of the four compartments of the ruminant stomach and determine the process of consuming dry matter and ending with liquid digestia. Students will dissect the stomach of a lamb taking a piece of each stomach and a sample of digestia from each and record observations using the dissecting microscope.
- One block period
- 96 Minutes
This lesson will discuss nutrients found in the feeds we give our animals. Powerpoint included discussed carbohydrates, proteins, vitamins, minerals, fats/oils, and water. Includes a lab for testing foods for nutrients available.
