Description

The amount of animal production from pasture by conven­tional grazing system in Japan stays at low level as 300 kg body weight gain of steers per hectare in one grazing period. This is supposedly caused by the following problems concerning graz­ing in Japan ; cold or hot temperature, rainy season, steep slope pasture, low fertilizer application, sharp seasonal fluctuation of grass production (spring flush, summer depression), faulty warm-up grazing, lots of blood-sucking insects and diseases (piroplasmosis, pneumonia etc.). Settling these problems, we have developed a new short rot­ational grazing system to get three times animal production (1,000 kg body weight gain per hectare).
