Here are a few exerps from these articles, but you should read the whole articles.
The calf's ability to absorb immunoglobulins decreases rapidly with age. This is why it is recommended
that calves consume colostrum within the first 2 hours following birth. Two quarts of colostrum should
be administered by drench or bottle, followed by 2 more quarts 4 to 6 hours later.8 Gut closure will start to occur after consumption of any liquid. Once this happens, the calf's ability to absorb immunoglobulins decreases.

Under grazing situations, it is best to administer a single fluid feeding so that the calf is handled only once. In this case, it is important to use an esophageal feeder. The esophageal feeder will allow a 3-L volume to be easily administered. This volume is not excessive for the calf, but will allow a large amount of Ig to be administered in a single fluid feeding.

Accordingly, calves should consume a minimum of 2 liters of colostrum within their first hour of life followed by an additional 2 liters over the next 6 to 12 hours. Timing of colostrum intake is critical because the intestines ability to absorb antibodies declines as the calf ages. Intestinal absorption progressively lessens after 12 hours of age and complete gut closure typically results after 24 hours.
