Recently the dairy husbandry in China reveals profound progress; the trend of which principally localizes in northern agricultural and grassland areas. Steady progress of people's income accelerates the rise of dairy husbandry, accompanying the tendency of farming conversion from traditional crop cultivation to dairy husbandry. With the rapid development of dairy production, forage supply is getting starved, and serious degradation of natural grasslands, which had been long applied properly for traditional pastorals before becomes apparent in each place. For the resolution, various organizations have been concentrating on (1) efficient utilization of maize residues, (2) renovation of degraded grasslands, and (3) expansion of cultivation of silage maize, improved forages, and fodder root crops. The situation that the annual increasing rate in cow number averages 15-20% brings various problems in turn. The fact indicates how to balance cattle feeding number, milk processing capacity, and forage productivity each other is one of the most important subjects for the development of each dairy husbandry.
