　　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.

　　布魯斯·科克倫(Bruce Cochrane)寫道，據(jù)加拿大大草原生豬中央進(jìn)行的研究顯示，群居的母豬要是有所選擇更趨向于低溫環(huán)境。大草原生豬中央的科學(xué)家認(rèn)識(shí)到群居母豬的居住舉動(dòng)，他們正在挖掘此項(xiàng)科技的價(jià)值，允許母豬調(diào)節(jié)住所環(huán)境的溫度。這項(xiàng)科技目的是利用群居母豬的習(xí)慣使其四處活動(dòng)并忍受更低的溫度。大草原生豬中央的工程研究科學(xué)博納多(Bernardo Predicala)博士解釋說(shuō)：“科學(xué)家研制了一套增補(bǔ)加熱系統(tǒng)，它允許母豬使用開關(guān)增添房屋溫度?！?/p>
