Title: Calculate the feed conversion ratio (FCR).
Course: Biological Applications in Agriculture (18308-I) > Section: Understanding Fundamentals of Animal Nutrition

Calculation should include

- average daily gain (i.e., final weight minus starting weight, divided by the animal's age in days)
- feed conversion ratio (i.e., feed intake divided by average daily gain).

Calculation of the FCR is critical to planning nutrition, marketing, and harvesting systems and is dependent upon the species, environment, and type of feed.

Process/Skill Questions:

- What information about feed components is needed to calculate the FCR? What formula is used?
- How does component quality affect FCR?
- How do disease and health challenges affect FCR?
