Animal Histophysiology

Research

Our research aims to investigate the physiological mechanisms involved in safe and efficient animal production. Current studies focus on the endocrinological and immunological functions of the reproductive and digestive organs in animals and poultry.

1) Studies on the innate immune functions in male and female reproductive organs and digestive tract that play roles in host defense and reproduction in poultry (Yoshimura, Y.)

2) Prevention and treatment of mastitis by investigation of mammary innate immune system in cow and goat. Effect of colostrum on immune system and nutrient status of cow. (Isobe, N.)

3) Regulation of immune function in reproductive and intestinal mucosa in poultry. Health promotion by probiotics. Relationship between egg formation and immune system. (Nii, T.)
