[翻译]澳大利亚的一项研究:给猪饲喂含鱼产品的饲料

作者:来源:时间:2008-06-10 15:03点击:

澳大利亚科学家发现一种可以降低猪肉中脂肪含量的方法:给猪饲喂含鱼产品的饲料。
    他们宣称,给猪饲喂含鱼产品饲料的猪肉富含omega-3型脂肪酸,这种猪肉可以预防心脏病。这些酸可分解甘油三酸酯,并降低血液中的脂肪含量。
优势:
澳大利亚南部的一位研究者Alison Coates说人吃这种猪肉非常有益。
    这项研究由Barlett 及澳大利亚的猪肉委员会联合进行。
给试验的受试者每周食用富含omega-3的猪肉200g,连续食用两周。结果是甘油三酸酯以及DHA脂肪含量降低。
   “实验结果是细胞膜中的有益的脂肪成分含量升高,从而降低了有害脂肪在体内的流通,从而降低心脏病的风险。”Coate博士说。
鱼香味
Coates博士说经研究,这种猪肉或者其它富含omega-3型脂肪酸的食品并没有鱼香味。“我们用多重评估标准来评估,添加含鱼产品的饲料和不添加含鱼产品的饲料在感观上没有什么不同。
澳大利亚的一些猪舍开始使用这种饲料,这种饲料对家禽场也是有用的。
但是在牛场和羊场不大可能投入使用,因为反刍动物有不同的消化系统,使用这种饲料不太合适。

Australian research: feed fish food to pigs
// 18 Jan 2007
     Australian scientists have found a way to reduce the amount of fat in pork by feeding fish meal to pigs.
     This, they claim, will lead to produced pork which is rich in omega-3 fatty acids, which should prevent the prevalence of heart diseases.
These acids are known to break down triglycerides and reduce fat levels in the blood.
Benefit
     University of South Australia researcher Alison Coates said people could now benefit from eating enriched pork instead.
    The study was set up with Bartlett Grain and Australian Pork.
Study participants were fed five 200 g serves of the omega-3-rich pork each week for a couple of weeks, with the results showing a decrease in triglyceride, or DHA fats.
"There was an increase in the incorporation of good fats into cell membranes, and what that did was reduce the bad fats in circulation, which reduces the risk of heart disease," Dr Coates said.
Fish smells
    Dr Coates said concerns that the pork or other omega-3-enriched foods would smell like fish were unfounded. "We did multiple evaluations of this and there was no different in the sensory perceptions," she said.
    Several piggeries across Australia are beginning to use the odour-free feed and it has also been made available to poultry farms.
     However, it appears unlikely the process can be replicated in cows or sheep, because ruminants have different digestive systems.
