title: [Extensive grazing and designed feeding with supplemented legume forages on natural grassland].
abstract: 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. Adding 20% legume forages to the diets for wethers could make the live body weight get a 40%-65% increase, achieving 52-61 kg in October extending to December. Forage production, animal nutrition and animal production were the three relatively primary factors for grassland management while focusing on grazing. Some terms such as eating-well, eating-well degree, eating-full, eating-full degree, extensive grazing and designed feeding were also defined respectively in this paper.
