摘要 选择35±2日龄断奶、健康无病、生长状况良好的杜长大三元杂交断奶仔猪60头,随机分为4个处理组,3个试验组猪分别饲喂含双乙酸钠0.2%、0.4%、0.6%的日粮,以研究双乙酸钠对生长肥育猪生长性能、胴体指标及肌肉品质的影响。试验结果表明,0.4%双乙酸钠日粮组明显改善生长肥育猪日增重(P<0.05),双乙酸钠日粮对生长肥育猪饲料利用效率作用不明显(P>0.05);0.4%与0.6%添加双乙酸钠组能降低背膘厚,增加眼肌面积(P<0.05),0.6%添加量组能提高胴体瘦肉率(P<0.05),不能改善生长肥育猪屠宰率(P>0.05);0.4%与0.6%添加双乙酸钠组对生长肥育猪有较高的滴水损失(P<0.05)。 Sixty pigs (DurocxLandracexYorkshire) of 35±2 date age,weaned, healthy, growth condition good, randomly allotted to four processing groups, three experimental groups were fed with containing Sodium Diacetate 0.2%, 0.4%, 0.6% of the diets to examine the effects of the growing-finishing pigs' growth performance, carcass indicators and muscle quality. The experiment results showed that 0.4%Sodium Diacetate diets significantly improved the growing-finishing pigs daily gain( P〈0.05 ),but the use efficiency was not obvious (P〉0.05). 0.4% and 0.6% sodium Diacetate group could reduce the backfat thickness and increase he loin eye muscle area (P〈0.05), 0.6% sodium Diacetate could increase the carcass lean-percentage( P〈0.05 ), could not improve the growing-finishing pigs dressing percentage(P〉0.05), 0.4% and 0.6% sodium diacetate group to growing- finishing pigs had higher drip loss( P〈0.05 ).
