Colostrum Collection


APS BioGroup collects only high quality first milking colostrum year-round from USDA Grade A dairies located in the Southwest United States.

First Milking Colostrum

Peptide levels from first milking

Peptide levels in first milking colostrum vs later milkings up to fourth day after birth

APS BioGroup only accepts colostrum from the first milking produced after the calf is born. Colostrum from the first milking has significantly higher levels of immunoglobulins (Ig), proline-rich polypeptides (PRPs) and other important factors.

In order to kick off the calf's immune system, it is vital the new born calf consume this first milking colostrum. Each cow produces about 18 liters of first milking colostrum at the time the calf is born. About half a gallon is fed to the calf within the first half hour after birth. About three hours later, the calf is given a boost of another half of gallon. APS then harvests the remaining 14 liters during a period of up to 16 hours after birth of the calf.

Year-round Collection

APS BioGroup Location

APS BioGroup is located in the Southwest of the United States which has the largest concentration of dairy cows in the world. Calving occurs year-round in this area because of the temperate climate. This enables APS to collect fresh colostrum all year. In much of the world (including New Zealand, Northern Europe, and Northern United States) most calving occurs in the spring because of the cycle of the seasons. As a result, colostrum products produced in these areas are manufactured only during the spring. Colostrum products from these regions are often not fresh — indeed, depending on the time of year, colostrum products from these manufacturers can be as much as a year old. And manufacturers in these regions often cannot respond to varying customer requirements during the year.

Highest Quality and Testing

All raw colostrum supplied to APS must meet 2003 Pasteurization Milk Ordinance (PMO) requirements. APS BioGroup colostrum is only collected from USDA Grade A dairies. Raw colostrum from each dairy undergoes a testing protocol to assure it is from the first milking, free of antibiotics, pesticides and other testing parameters.
