Understanding Brix Values in Colostrum

“The key is to get as many immunoglobulins (IgGs) into the calf as possible,” explains young animal specialist Henk Sijtsma. The Brix meter is a handy tool that allows you to measure the amount of IgGs in the colostrum. Henk emphasizes the importance of the quantity of colostrum. “Ideally, feed 10% of the body weight in colostrum within the first twelve hours, preferably within half an hour after birth. This usually means four liters of colostrum. At a Brix value of 22, this equates to 200 ml of IgGs. Don’t be alarmed if the colostrum has a Brix value of 20. This is not bad colostrum, but you should feed more liters of it or supplement it with colostrum powder to improve its quality.”
