摘要
猪舍饲环境丰富度是衡量猪福利化水平的一个重要指标。提高环境丰富度,使猪充分展现其生物特性,可在很大程度上提高猪只福利化水平。本文结合不同国家或地区的动物福利法律法规、经济发展水平和经济效益阐述现阶段猪舍饲环境丰富度普及程度差异性原因。目前市场上所提供的环境丰富度猪福利玩具以结构简单、机械性为主,其对猪的吸引力会持续减弱。近些年,研究者对农场动物认知性研究兴趣激增。依据动物的生理指标、行为表达及认知偏见推断,认知性的环境丰富度可能对其产生积极的情感,满足其精神层次需求,提高动物的福利水平。随着研究者对猪认知能力与动物福利了解的不断深入,推测猪舍未来环境丰富度将会朝着认知性的设备方向发展。
Environmental enrichment of the piggery is an important indicator of pig welfare.

Combined with the domestic and overseas status, from laws and regulations of animals＇ welfare, economic development level and benefit evaluation, this paper analyzes the reasons of the differences t-om universal degree of environmental enrichment in the piggery indifferent regions at present stage. Toys of pigs from current market show that features simple structure and mechanicalness resulting in decreasing the attraction for pigs to provide environmental enrichment in tile piggery, In recent years, researchers become more and more interest in searching the cognitive abilities of farm animals. Based on animals＇ physical signs, behavior and cognitive biases, Cognitive enrichment may cause positive emotion, meet the demand of pig spirit, and improve the welfare of pigs.
