摘要
研究了日粮碘水平对母猪繁殖性能、母猪和新生仔猪血清参数等指标的影响 .结果表明 ,日粮中添加 0 .1 5m g/kg碘足以防止母猪出现碘缺乏症 ,但添加 0 .50 ,1 .0 0 ,1 .50 mg/kg碘能分别提高产仔数 0 .99,0 .78,0 .2 5头 /胎 ;平均初生重可提高 9.0 4 % ( P<0 .0 5) ,9.57% ( P<0 .0 5)和 1 .0 6% ;平均出生窝重可提高 1 9.2 7% ( P<0 .0 5) ,1 2 .75% ,6.73 % .日粮碘水平对母猪血清参数、新生仔猪甲状腺重量无显著影响 ,而新生仔猪血清中 T3 的水平可分别提高 2 1 .3 6% ,3 3 .98% ,4 9.0 3 % ( P<0 .0 5) ;肝脏重量分别下降了 1 6.53 % ,1 0 .3 8% ,1 7.2 3 % ( P<0 .0 5) ;肾脏重量分别下降 4 .97% ,2 7.76% ( P<0 .0 5)和2 9.0 1 % ( P<0 .0 5) .
WT5”BZ]Effects of dietary iodine level on reproduction performance of gestation sow, serum parameters of sow and newborn piglets were studied The results showed that iodine deficiency of sow could be avoided by adding 0 15 mg/kg iodine in diet But the litter size could be increased 0 99, 0 78, 0 25 piglet per litter , average newborn piglets weight could be increased by 9 04%( P <0 05),9 57%( P <0 05), 1 06%, average litter weight could be increased by 19 27%( P <0 05), 12 75%, 6 73%, in trial group 1, 2, 3, which were fed with the diet adding 0 50, 1 00, 1 50 mg/kg iodine, respectively The serum parameters of sow and the thyroid weight were not affected by dietary iodine level, but the T3 level of newborn piglets were increased by 21 36%, 33 98%, 49 03%( P <0 05), the liver weight were decreased by 16 53%, 10 38%, 17 23%( P <0 05). The kidney weight were decreased by 4 97%, 27 76%( P <0 05) and 29 01%( P <0 05) in trial groups, respectively [WT5”HZ]
