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

Abstract

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.

Key words: Extensive grazing, Designed feeding, Eating-full, Eating-well, Legume forage
