CANADA - A research Scientist Ethology with the Prairie Swine Centre says studies are showing that enriching the living environment of pigs improves productivity at all stages of growth, Bruce Cochrane reports.Revisions to Canada's Code of Practice for the Care and Handling of Pigs require pork producers to provide multiple forms of enrichment, such as social enrichment, nutritional enrichment, sensory enrichment or occupational enrichment to the living environment of the animals at all stages of growth.Dr Jennifer Brown, a Research Scientist Ethology with the Prairie Swine Centre, explains the goal of enrichment is to provide biological benefit to the pigs and research shows a more varied environment results in reduced stress responses, reduced aggression and reduced injurious behaviors such as tail biting.
布鲁斯·科克伦(Bruce Cochrane)写道，据大草原养猪中心的一名个体生态学的研究科学家称，研究显示，丰富猪的生存环境能够提高猪在各个生长阶段的生产力。加拿大重新修订的生猪养殖与护理条例要求猪肉生产商，为牲畜在各个生长阶段的生存环境，提供多种形式的强化拓展，比如群居强化、营养强化、感觉强化或职业融合。大草原养猪中心的一名个体生态学的研究科学家Jennifer Brown博士说：“强化的目的是带给猪生物学的益处，研究显示，一个更加多样化的环境会减少猪的应激压力，减少猪的攻击行为以及减少猪的咬尾等有害行为。”
