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.
布魯斯·科克倫(Bruce Cochrane)寫道,據(jù)大草原養(yǎng)豬中心的一名個(gè)體生態(tài)學(xué)的研究科學(xué)家稱,研究顯示,豐富豬的生存環(huán)境能夠提高豬在各個(gè)生長階段的生產(chǎn)力。加拿大重新修訂的生豬養(yǎng)殖與護(hù)理?xiàng)l例要求豬肉生產(chǎn)商,為牲畜在各個(gè)生長階段的生存環(huán)境,提供多種形式的強(qiáng)化拓展,比如群居強(qiáng)化、營養(yǎng)強(qiáng)化、感覺強(qiáng)化或職業(yè)融合。大草原養(yǎng)豬中心的一名個(gè)體生態(tài)學(xué)的研究科學(xué)家Jennifer Brown博士說:“強(qiáng)化的目的是帶給豬生物學(xué)的益處,研究顯示,一個(gè)更加多樣化的環(huán)境會(huì)減少豬的應(yīng)激壓力,減少豬的攻擊行為以及減少豬的咬尾等有害行為。”
