Intrauterine growth-restricted piglets (IUGR) have a lower rectal temperature, whole-blood glucose, and lower glycogen storages at birth than normal piglets, giving them less energy to maintain body temperature and compete at the udder. The present paper investigated the effects of giving an energy supplementation three times after birth on rectal temperature, glucose levels, and growth until weaning in an on-farm trial. Eighty-eight newborn piglets were classified as IUGR (based on head morphology), placed under a heating lamp for one hour and allocated to one of four treatments-warmed water (WATER), glucose injection (GLUC), colostrum bolus (COLOS; porcine colostrum), and colostrum bolus and glucose injection (GLUC + COLOS)-before being placed at a nursing sow. Weight differences were found at day 21, with GLUC and GLUC + COLOS groups being the heaviest. Piglets in GLUC + COLOS had higher glucose levels at = 3, 6, and 9 h compared to the other treatments ( = 0.027), but from = 24 h and onwards, no difference was observed. For rectal temperature, no differences were observed. Collectively, these findings suggest that glucose injections at birth (i.e., as an energy source), one hour's exposure to warmth and the placement of piglets with a nurse sow to reduce competition, enhance the growth of IUGR piglets.
与正常仔猪相比，宫内生长受限仔猪（IUGR）出生时直肠温度较低、全血葡萄糖水平较低且糖原储备较少，这使得它们维持体温和在乳房处竞争的能量较少。本文在一项农场试验中研究了出生后三次补充能量对直肠温度、葡萄糖水平以及断奶前生长的影响。88头新生仔猪被归类为IUGR（基于头部形态），在加热灯下放置1小时，然后分配到四种处理之一——温水（WATER）、葡萄糖注射（GLUC）、初乳大丸剂（COLOS；猪初乳）以及初乳大丸剂和葡萄糖注射（GLUC + COLOS），之后再放置到哺乳母猪处。在第21天发现了体重差异，GLUC组和GLUC + COLOS组最重。与其他处理相比，GLUC + COLOS组仔猪在3、6和9小时时的葡萄糖水平更高（P = 0.027），但从24小时及以后，未观察到差异。对于直肠温度，未观察到差异。总体而言，这些发现表明出生时注射葡萄糖（即作为能量来源）、1小时的温暖环境暴露以及将仔猪与哺乳母猪放置在一起以减少竞争，可促进IUGR仔猪的生长。
