title: An electrophoretic characterization of serum proteins of the collared peccary (Tayassu tajacu).
abstract: Serum proteins of the collared peccary (Tayassu tajacu) were analyzed by agarose gel electrophoresis for wild adult males and females, nursing young, and reproductively-active females in captivity. Electrophoretic profiles of the adult peccary showed at least six distinct protein bands corresponding to the fractions: albumin, alpha-1, alpha-2, beta-1, beta-2, and gamma globulin. Globulin fractions of the peccary had different mobilities from the domestic swine. The only sexual dimorphisms were associated with the beta globulin:albumin ratio and the albumin:globulin ratio. Ingestion of colostrum in 1-day-old neonates was marked by a very large increase in gamma globulins. The only significant difference between pregnant and lactating females was in the alpha globulin:beta globulin ratio. Lactating females had higher concentrations of alpha-2 globulin than non-pregnant females.
