a practical field method for the rapid determination of colostrum
quality prior to feeding the newborn calf. This simple field method
helps insure the successful transfer of immunity.
Control Program: A
quality control program can be instituted program that starts with
vaccinating dams, properly collecting, assessing & storing
colostrum, and ends with feeding newborn calves the proper volume and
quality of colostrum at optimal times. Colostrum that does not
measure-up may be separated and feed to older calves that have
already been given an initial dosage of high quality colostrum.
of the primary reasons the COLOSTROMETER™
become such a valuable tool to dairyman, is that it allows the timely
feeding of only high quality colostrum to newborn calves during their
optimal absorption time frame of not more than 24 hours after birth.
Versus Quantity: An
adequate amount of antibodies (Ig) must be absorbed by the newborn
calf within 24 hours of birth in order to ensure the calf has
received adequate protective levels.
factors are responsible for determining the quantity of Ig available
to the calf: 1. Concentration of Ig in the colostrum 2. Volume of
colostrum available. Between these two factors, the newborn calf
should be fed between 150 to 200 grams of Ig within the first 24
The COLOSTROMETER™ provides
the dairyman with the ability to assess the quality of the colostrum
by measuring the quantity of antibodies present. If the colostrum
sample registers in the green zone, or between 140 to 50 mg/ml, then
a total volume between about 1.5 liters (1.5 quarts) to 3 liters (3
quarts) should be fed to the new born calf, respectively, to achieve
a total of at least 150 grams of Ig.
