Arithmetic mean weighted by the volume of colostrum #1 (specific gravity = 1048, 19.0% Brix), colostrum #2 (specific gravity = 1039, 15.8% Brix), and colostrum #3 (specific gravity = 1043, 16.6% Brix).

Deviation of measured values from expected values calculated as follows: (expected – measured)/expected × 100 [%].
