Serum protein concentrations and enzyme activities, as functions of age and sex, in Sinclair (S-1) miniature swine.
Venous blood samples were collected monthly from 60 male and 60 female Sinclair (S-1) miniature swine from 1 through 36 months of age. Serum total protein concentration increased linearly from 1 through 10 months of age and remained stable thereafter with no sex related difference. Serum albumin concentration decreased from 1 through 3 months, increased from 3 through 8 months and decreased from 14 through 36 months. From 2 through 36 months, serum alpha-globulin concentration decreased; whereas, serum beta-globulin concentration increased. Serum gamma-globulin concentration increased markedly from 1 through 3 months and continued to increase through 36 months of age. From 10 through 36 months, males had a greater mean serum gamma-globulin concentration than did females. Serum total globulin concentration increased most rapidly from 1 through 3 months, less rapidly from 3 through 18 months and remained stable thereafter. Serum albumin/globulin ratio decreased sharply from 1 through 3 months and continued to decrease from 6 through 36 months with females having a greater mean concentration than males. Serum glutamic-oxaloacetic transaminase activity decreased from 1 through 30 months with males having a greater mean activity than females from 7 through 36 months of age. Serum alkaline phosphatase activity decreased from 1 through 36 months of age with no sex related difference. Serum lactic dehydrogenase activity decreased from 1 through 30 months with females having a greater mean activity than males from 24 through 36 months of age.
