摘　　要：以产活仔 1 2头以上的经产母猪为对象 ,研究蛋白质水平分别为 1 1 .5 %、1 3 .8%、1 5 .9%、1 8.0 %和2 0 .2 % ,相应的赖氨酸为 0 .61 %、0 .74 %、0 .87%、1 .0 %和 1 .1 2 %的 5种等能饲粮对母猪繁育、泌乳及血浆尿素氮和游离氨基酸含量的影响。结果表明 :随着蛋白质和赖氨酸摄入量的提高 ,母猪泌乳期失重减少 (P <0 .0 5 ) ,泌乳量则显著提高 (P <0 .0 5 )。仔猪 2 0和 3 5日龄的窝重均显著受母猪饲粮营养水平的影响 (P <0 .0 5或P <0 .0 1 )。血浆尿素N随蛋白质和赖氨酸水平的提高而提高 (P <0 .0 5 ) ,但血浆游离氨基酸总含量无显著差异。无论母猪繁育效果和泌乳性 ,均以第 4组饲粮即母猪日摄入蛋白质 868g,赖氨酸 4 8.3g时 。sows nursing 12 litters were used to study t he effects of five dietary protein levels(11.5%,13.8%,15.9%, 18.0% and 20.2%)or five lysine levels(0.61%,0.74%,0.87%,1.0% and 1.12%)respectively on reproductive and foster ing performance,milk yield,plasma urea nitrogen(PUN)and plasma amino acid during a 35d lactation period.The results suggested that with the protein and lysine intake increased,the body weight loss of sows during lactation period decreased(P<0.05),The milk yield and litter weight on 20 and 35 dincreased with increased dietary protein or lysine intake (P<0.05 or P<0.01).The PUN concentration increased linearly with increasing dietary protein(lysine)levels.protein(lysine)levels did not significantly affect the plasma total amino acid content.The best reproductive and lactation performance can be achieved when the sows receive 868g protein and 48.3g lysine daily.
