Animal Science Division
The goal of this division is to discover novel functions in animals and applying such discoveries for the technological advancement of domestic animal production. The research will contribute to sustainable and efficient production of safe food for humans derived from animal products. Current research fields are: breeding and genetics based on modern genomic analysis, reproductive biology and biotechnology for enhanced reproductive performance, applied nutritional physiology and feed evaluation for improved nutritional management, ecology and neurophysiology for better animal management and viability, and fundamental histology and molecular physiology to enhance veterinary production and health.
 
Animal Breeding and Genetics
 

The Laboratory of Animal Breeding and Genetics conducts
various studies on the detection of and analyses for
industrially useful genes in livestock, using molecular
methods, along with phylogenetic studies of livestock,
emphasizing on poultry.
 
1) Preservation of poultry resources, gene mapping, 
    and genetic diversity study (Tsudzuki, M.)

2) Molecular phylogenetic study based on genome and
    gene function of animals and birds (Nishibori, M.)

Animal Reproduction
 

The Laboratory of Animal Reproduction conducts
various studies on artificial manipulations of germ cells,
and biochemical and molecular analyses of maturation,
ovulation and fertilization of oocytes aiming at the
improvement and preservation of livestock resources.
 
1) Artificial manipulation of germ cells (Maeda, T.)
2) Reproductive endocrinology (Shimada, M.)

Animal Nutrition and Feeding
 
The main goal of the Animal Nutrition and Feeding Laboratory
is to improve ruminant feeding systems for viable and healthy
production through elucidating the complex relationships between nutritional response and various dietary and physiological factors.

1) Digestion site and extent of diets and nutrient
    metabolism by splanchnic tissues (Taniguchi, K.)
2) Kinetics of various amino acids and urea (Obitsu, T.)
3) Secretion and action of gastrointestinal hormones
    (Sugino, T.)

Animal Behavior and Physiology
 
Our goal is to improve the productivity of domestic animals using effective animal management techniques. We investigate the physiological and behavioral responses of domestic animals/fowls to their environment to predict their needs and health.

1) Physiological aspect of layers and dairy cows under hot or stress environments, and brain functions regulating the behavior of chickens（Bungo, T.）
2) Effect of high environmental temperature on the function of central nervous system of chickens (Kawakami, S.)

Animal Histophysiology 

 

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) Ovarian follicular growth and disorder, mastitis
    and mammary immune system (Isobe, N.)
