“Colostrum is crucial for newborn farm animals. They receive no passive transfer of immunity via the placenta before birth, so any antibodies that they need have to be ingested. This oral transfer of immunity can occur because the newborn’s stomach is porous. This means that large proteins (such as antibodies) can pass through the stomach wall. The newborn animal must receive colostrum within 6 hours of being born for maximal transfer of antibodies to occur. The stomach wall remains somewhat open up to 24 hours of age, but transfer is more limited.^[23]

Livestock breeders commonly bank colostrum from their animals. Colostrum can be stored frozen but it does lose some of its inherent quality. Colostrum produced on a breeder’s own premises is considered to be superior to colostrum from other sources, because it is produced by animals already exposed to (and, thus, making antibodies to) pathogens occurring on the premises. A German study reported that multiparous mares produced on average a liter (quart) of colostrum containing 70 grams of IgG.^[24]

Bovine colostrum is produced by cows for their newborn calves. In many dairy cow herds the calves are not permitted to nurse; rather, they are fed colostrum from a bottle or by stomach tube and later milk from a bottle then a bucket.”

Put up just shy of one qaurt of sheep colostrum in small portions into the freezer between yesterdays and todays morning milking. I am freezing in trays and then double bagging the frozen cubes for future use if needed.

The link above is to a excellent article, and they talk about what I am doing, the gold standard if you need to help a lamb out is to be able to give colostrum from older adult female ewe’s from your own flock, as they will have the best shot possable for providing protection for your own land and barns.
