* For leap years, February has 29 days and the number of each day after February 28 is one greater
than the number given in the table.
Table 11.4 The Number of Each Day of the Year
Example A. A heifer calf born on April 2 from a two-year-old cow and weaned on October 15 weighed
500 pounds. Her dam was a two-year-old cow. The calf’s birth weight is not available,
therefore it is presumed that this heifer’s birth weight is 65 pounds. Calculate of the heifer’s
adjusted weight?
Solution:
Heifer:
weaning wt. − birth wt. Dams Age
Adjusted 205-day wt. = ——————–———— x 205) + birth wt. + Weaning wt
age in days Adjustment
(500 – 65)
Adjusted 205-day wt. = [ ———— x 205] + 65 + 60
169*
*Age in days = Oct. 15 (288th day of yr. from Table 11.4 above) − Apr. 2 (92nd day of yr.)
365 − 288 + 92 = 169 days
