摘　　要：文章旨在探究亚麻籽粕对生长育肥猪生长性能、胴体品质和肌肉脂肪酸组成的影响。试验选取体重(71.49±1.48)kg、健康状况良好的生长猪160头,按照公母对半的原则随机分为4组,每组5个重复,每重复8头。分别饲喂使用0%、4%、8%和12%的亚麻籽粕替代豆粕的试验日粮。试验为期42 d。结果表明,4%和8%亚麻籽粕组育肥猪终末体重显著提高2.84%和4.04%(P<0.05);4%和8%亚麻籽粕组育肥猪平均日增重显著提高8.13%和12.14%(P<0.05);8%亚麻籽粕组育肥猪料重比显著降低7.94%(P<0.05);此外,日粮添加亚麻籽粕对育肥猪平均日采食量无显著影响(P>0.05)。日粮添加4%的亚麻籽粕显著降低育肥猪肌肉中肉豆蔻酸(C14:0)含量(P<0.05),显著降低硬脂酸(C18:0)含量(P<0.05);4%和8%的亚麻籽粕组育肥猪肌肉棕榈酸(C16:0)含量显著降低(P<0.05),总脂肪酸含量显著提高(P<0.05);日粮添加亚麻籽粕可显著提高育肥猪肌肉二十碳烯酸(C20:1)含量(P<0.05);8%亚麻籽粕组育肥猪肌肉饱和脂肪酸含量显著降低(P<0.05),单不饱和脂肪酸含量显著降低(P<0.05)。在本试验条件下,亚麻籽粕最适添加量为8%。The aim of this experiment is to investigate the effects of flaxseed meal on the growth performance,carcass quality,and muscle fatty acid composition of fattening pigs.160 growing pigs with a weight of(71.49±1.48)kg and good health were selected and randomly divided into 4 groups according to the principle of male and female half,with 5 replicates in each group and 8 pigs in each replicate.Feed experimental diets with 0,4,8,and 12%flaxseed meal instead of soybean meal separately.Test duration 42 days.The experimental results showed that adding 4%and 8%flaxseed meal to the diet significantly increased the final body weight of fattening pigs by 2.84%and 4.04%(P<0.05);The addition of 4%and 8%flaxseed meal to the feed significantly increased the average daily weight gain of fattening pigs by 8.13%and 12.14%(P<0.05);The addition of 8%flaxseed meal to the feed significantly reduced the feed weight ratio of fattening pigs by 7.94%(P<0.05);In addition,adding flaxseed meal to the feed had no significant effect on the average daily feed intake of fattening pigs(P>0.05).Adding 4%flaxseed meal to the diet significantly reduced the content of myristic acid(C14:0)in the muscle of fattening pigs(P<0.05),and significantly reduced the content of stearic acid(C18:0)(P<0.05);The addition of 4%and 8%flaxseed meal to the diet significantly reduced the content of palmitic acid(C16:0)in the muscle of fattening pigs(P<0.05),while the total fatty acid content significantly increased(P<0.05);The addition of flaxseed meal to the diet significantly increased the content of eicosenoic acid(C20:1)in the muscle of fattening pigs(P<0.05);The addition of 8%flaxseed meal to the diet significantly reduced the saturated fatty acid content in the muscle of fattening pigs(P<0.05),and the monounsaturated fatty acid content significantly decreased(P<0.05).Under the conditions of this experiment,the optimal amount of flaxseed meal added is 8%.
