Laboratory of Animal Nutrition and Feed Science Katsuki KOH Professor manure composting Environmentally friendly feed Low emission Intensive and extensive animal production is believed to be one of the major contributors to environmental pollution due to excretion of large volumes of feces and urine containing environmental load substances, such as nitrogen and phosphorus. Our aim is to reduce the excretion of these substances by modifying feeding programs and their nutrient balance. In addition, we are developing a technique to reduce the environmental load of substances emitted during manure composting. Environmentally friendly feed A B C D A B C Mushroom cultivated on substrates supplemented with apple pomace and cattle feed made from their spent substrates International collaborative research project with Jambi University, Indonesia (Upstream and downstream strategy of ammonia mitigation in curtain-sided poultry farm) Bioresource Science Division Low emission manure composting Laboratory of Reproductive Function in Mammals Koh-ichi HAMANO Professor Sperm motility Thermotaxis Chemotaxis Hyperactivation Capacitation The Laboratory of Reproductive Function of Mammals investigates the reproductive function in male animals to propagate farm animals and mammals efficiently. We study the male germ cells of bovines, goats, and mice to elucidate fertilization mechanisms. Sperm migrate with thermotaxis and chemotaxis. Sperm induce hyperactivation and acrosome reaction after capacitation. We analyse thermotaxis, chemotaxis and hyperactivation of mammals. Physiological mechanisms of mammalian sperm motility and capacitation A B C D A B C Analysis of bull sperm motility with head motion using CASA . Computer Assisted Sperm Analysis (CASA) system. Bioresource Science Division Signal transduction mechanisms of sperm thermotaxis and chemotaxis. Hyperactivation and acrosome reaction of mammalian sperm 13
