21. Average Daily Gain
The amount of gain divided by the number of days in the feeding period
Impacted by:
Genetics
Health
Nutrition
Etc.
3+ lbs/day is common

Feed efficiency (F/E) is the pounds of feed necessary to increase the body weight of the animal by one pound.
Rule of Thumb: F/E = 1% of body weight and moves toward 6.
Example: A 300 pound calf would have an expected feed efficiency equal to 1% of its body weight but moved toward 6. In other words 1% of 300 is 3 but moved one step toward 6 makes the F/E = 4.
