CANADA - Research conducted by the Prairie Swine Centre shows, given the choice, group housed sows will tend to select lower temperatures, writes Bruce Cochrane.In recognition of the move to group sow housing scientists with Prairie Swine Centre are exploring the value of technology that allows the sows to regulate the temperature of their environment.The technology is designed to take advantage of the ability of group housed sows to move around and to tolerate lower temperatures.Dr Bernardo Predicala, a Research Scientist Engineering with the Prairie Swine Centre, explains scientists developed a supplemental heating system that allows the sows to use a switch to increase the temperature of the room.

　　布鲁斯·科克伦(Bruce Cochrane)写道，据加拿大大草原生猪中央进行的研究显示，群居的母猪要是有所选择更趋向于低温环境。大草原生猪中央的科学家认识到群居母猪的居住举动，他们正在挖掘此项科技的价值，允许母猪调节住所环境的温度。这项科技目的是利用群居母猪的习惯使其四处活动并忍受更低的温度。大草原生猪中央的工程研究科学博纳多(Bernardo Predicala)博士解释说：“科学家研制了一套增补加热系统，它允许母猪使用开关增添房屋温度。”
