Hyper-prolific sows give birth to large litters and up to 25% of piglets born have been subjected to intrauterine growth restriction (IUGR). The aim of this study was to test whether an oral administration of glucose impacts the survival rate and body weight gain of IUGR piglets at weaning. Different methods (injection versus oral administration of glucose 6 mL or 12 mL, respectively) were tested on IUGR piglets at litter equalization (i.e., when piglets are handled the first time at 5-20 h after birth). Injecting glucose generated the highest whole-blood glucose level + 3 h after treatment, however, after this no differences were observed. Of the 237 IUGR piglets studied, 98 piglets died or were removed from the nurse sow (41%). Rectal temperature at litter equalization (0 h) was related to the survival of the piglets with an average temperature of 37.1 ± 0.1 °C in surviving piglets and 36.6 ± 0.1 °C in piglets that died. In conclusion, providing these extra management actions at litter equalization is too late to help piglets that have a low rectal temperature and are low on energy. More research investigating different management methods to deal with IUGR piglets are needed as many of these underdeveloped piglets will not survive.
高产母猪产仔数多，所产仔猪中高达25%受到子宫内生长受限（IUGR）的影响。本研究的目的是测试口服葡萄糖是否会影响IUGR仔猪断奶时的存活率和体重增加。在仔猪均衡化时（即出生后5 - 20小时首次处理仔猪时），对IUGR仔猪测试了不同方法（分别为注射葡萄糖与口服6 mL或12 mL葡萄糖）。注射葡萄糖在治疗后3小时产生了最高的全血葡萄糖水平，然而在此之后未观察到差异。在研究的237只IUGR仔猪中，98只仔猪死亡或被从哺乳母猪身边移走（41%）。仔猪均衡化时（0小时）的直肠温度与仔猪的存活率有关，存活仔猪的平均温度为37.1±0.1℃，死亡仔猪的平均温度为36.6±0.1℃。总之，在仔猪均衡化时采取这些额外的管理措施，对于直肠温度低且能量不足的仔猪来说为时已晚。由于许多发育不良的仔猪无法存活，因此需要更多研究来探索处理IUGR仔猪的不同管理方法。
