An electrophoretic characterization of serum proteins of the collared peccary (Tayassu tajacu).
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.
