Means to Determine First Milking Colostrum

Means to Determine First Milking Colostrum

TOTAL SOLIDS

Total solids are determined by dividing the dried solids by the original quantity of liquid started with.

EXAMPLE: 782.7 Kg Dried Solids divided by
3207.9 Kg Colostrum Liquid
= 24.40% TOTAL SOLIDS

Refer to "Total Solids" column in the following table from FUNDAMENTALS OF DAIRY CHEMISTRY:

 

PROTEIN

Use either Kjeldahl method or licensed testing laboratory.
EXAMPLE: License laboratory Kjeldahl*=53.01% Protein
53.01 divided by 4.1 (100 divided by 24.4 total solids)=
12.93% TOTAL PROTEIN

Refer to "Total Protein" column in following table from FUNDAMENTALS OF DAIRY CHEMISTRY:

LACTOSE

 

Lactose has a great influence on allergic-like responses experienced by some individuals due to the lack of lactase and B Galactodidase.

(NOTE: DUE TO LACTOSE CREATING ALLERGIC-LIKE RESPONSES, LACTASE CAN BE USED TO DEGRADE THE LACTOSE)

Unlike the immunoglobulin IgG, lactose rises in value from the first milking through the subsequent several milkings. This is another gauge for determining quality of colostrum.

EXAMPLE: Sequence Health's 
Serial #542=9.60% lactose
9.60% lactose divided by 4.10
(100 divided by 24.4% Total Solids)
=2.34% LACTOSE or less than
6 hours post parturition

Refer to "Lactose" column in

following table from FUNDAMENTALS OF DAIRY CHEMISTRY:


IMMUNOGLOBULINS

Immunoglobulin IgG has long been the
parameter by which the colostrum value has been measured.

Total Solids, Proteins, Lactose and Immunoglobulins are very definite indicators as to which milkings of colostrum have been collected. This determines the value of colostrum.

To further identify colostrum value the percents of IgG<1 and IgG2 can be used to determine value.

One or two of these factors can be altered but it is difficult to alter all four factors to duplicate 1st milking colostrum.

VMRD's or ICN Biomedical Inc. SRID's (Single Radial Immunodiffusion) are used for determining the value of antibodies (immunoglobulins) in colostrum.

The above table from ICN Biomedical Inc. indicates that in 1st milking colostrum, the IgG1 content is between 90-95% of the total immunoglobulin G content; whereas plasma or serum would be 50-60% IgG1 and the remaining portion is IgG2.

IgA and IgM remain about 13.8% of the total IgG in colostrum as well as in the plasma or serum.

EXAMPLE: Powder reconstituted 24.4g powder to 75.6 g water.
This approximates the total solids recovered
from the 542 serial.
A factor of 4.10 (100g ÷ 24.4)
Serial 542: IgG 3830 = 3.83%
3.83% x 4.1 (factor) = 15.70%
15.70 ÷ 53.01 = 29.62%
