N-acetyl-beta-D-glucosaminidase (NAGase) in porcine milk.

Sow milk contains a high basal level of the lysosomal enzyme N-acetyl-β-D-glucosaminidase (NAGase). The level is extremely high in colostrum. High basal levels seem to hide inflammatory changes. Therefore NAGase did not prove to be as good an indicator for porcine agalactia syndrome as reported for mastitic bovine or ovine milk.
