Abstract
WEIGHT per day of age is commonly used to assess growth in beef calves. It can be shown that there is a very high correlation between weight per day of age and gain per day (Fig. 1), and since the former is a simpler calculation, and does not require a birth weight, it appears on the surface to be a practical substitute for the latter.
