[Extensive grazing and designed feeding with supplemented legume forages on natural grassland].

Livestock needs to be fully stuffed and fed well. Eating-well can compensate eating-full, and can rapidly increase the body weight of livestock, shorten its feeding period, enhance its production, and protect natural grassland from overgrazing. A designed feeding based on extensive grazing on natural grassland by supplementing rich crude protein-contained forage might be a new trend for optimizing the animal husbandry on grassland.
