试验选用健康无病的杜长甘三元杂交育肥猪40头,以水泥地面传统养猪为对照,研究了干旱半干旱区生物发酵床养猪效能和对猪肉品质的影响.试验结果表明,与传统养猪相比,头均日增重提高12.46％,差异显著(P＜0.05)；头均饲料消耗量节省5.75％,头均纯收益增加89.57元；试验组必需氨基酸总量(EAA)、主要鲜味氨基酸总量(FAA)显著高于对照组(P＜0.05)；主要重金属残留量与传统养殖差异不显著(P＞0.05),低于国家行业标准；试验组猪肉饱和脂肪酸(SFA)含量极显著高于对照组(P＜0.01),不饱和脂肪酸(UFA)含量差异不显著(P＞0.05),常规矿物质元素含量差异不显著(P＞0.05).通过试验,在干旱半干旱区应用生物发酵床养猪可保障动物福利,经济效益显著,肉品营养成份和风味优于传统饲养方式,重金属残留低于国家行业标准,品质安全健康.但由于饱和脂肪酸含量高,高血脂类人群应控制多食.%The experiment selected 40 healthy and crossbred grow-finishing pigs (durocX landraceX white),as traditional method of pig feeding on cement ground for control group,carried out the impact study on efficiency and nutritional composition on the basis of bio-bed system in arid and semi-arid areas.The experiment indicated,compared with the traditional method,average daily gain weight was enhanced 12.46% per pig and showing as significant difference (P<0,05),feed ration was saved 5.75% and net profit was increased 89,57 Yuan per pig.The essential amino acid (EAA) and flavor ammo acid (FAA) of experimental group was significant higher than the control group (P<0.05);The heavy metal residues was no significant difference (P>0.05) and remained lower than the standard in operation;The content of saturated fatty acid (SFA) in experimental group was higher than the control group extremely remarkably (P<0.01),the content of unsaturated fatty acid (UFA) and general mineral substance were no significant difference (P>0.05).The experiment proved that the technology of feeding pig as bio-bed system could guarantee the animals' welfare and economic benefit remarkable.The nutritional composition and meat flavor under bio-bed system is better than the results from tranditional method.The meat quality is healthy and safty,and the heavy metal residues is lower than standard in operation.The hyperlipidemia patient should less eat due to high content of saturated fatty acid (SFA).
