With cattle there is only one udderful of colostrum, due to a hormone flux at the time of birthing that shuts off colostrogenesis. From that time forward, colostrum begins a transition to normal milk (Fundamentals of Dairy Chemistry). The levels of the beneficial components of colostrum immediately begin to decline post parturition. For example, after six hours post calving, 6.3% of the total solids in the colostrum is albumin (mostly immunoglobulin), but after twelve hours only 3% is albumin.

Fact 2: ONLY THE FIRST MILKING IS TRUE COLOSTRUM

The first milking harvests eighty percent of the colostrum. As time passes after the first milking, the small amount of colostrum remaining in the udder awaiting extraction by subsequent milkings transitions to normal milk. With other than first six hour colostrum, products sold as "colostrum" may contain more dried milk than colostrum.  Current regulations do not prevent a company from advertising up to five milkings as "colostrum", when the fifth milking is less than 1% true colostrum.

Fact 3: SYNERGISM IS LOST AFTER SIX HOURS

Not only do the levels of the beneficial components of colostrum in the udder decline over time, but the proportions of the components also change. This is critical because the components of colostrum work together, in accord with nature's perfect design. The various components working together accomplish more than the sum of the components working independently, a biological phenomenon known as synergism. To achieve maximum synergism the components of colostrum must be present in the proportions existing near the time of calving.

Because of the above reasons it takes less first milking, first six hour colostrum to achieve results, and better results, than with other colostrum. Synertek lozenges contain 200 mg of pure first milking, first six hour colostrum - true colostrum - and it requires only two or three of them daily to maximize benefits.
