| Research Abstract |
The summary of the research achievements are; 1. Characterization of porcine milk proteins, 2. Evaluation of secretion volume and immunoglobulin A and G concentrations in sow colostrum from anterior to posterior teats, 3. Analysis of cell population in porcine colostrum, and change in lymphocyte percentage in total cells during 24 hrs after parturition, 4. Identification of characteristic genes expressed in porcine colostral T cell in comparison to blood T cell, 5. Effect of colostrum intake during first 24 hrs of life on the development of immunity, especially on humoral immunity, in piglets. 6. Analysis on developmental change in gene expression profile in porcine ileum. This research revealed variety and function of porcine colostral protein and cells. Additionally, this research suggested that colostrum intake affect the development of humoral immunity in piglet and that gene expression profile in ileum drastically changes at a certain period of the development.
