摘要: 本试验旨在探讨代乳品的使用对低初生重仔猪生长性能的影响。选取山东省某种猪场内240头低初生重仔猪以及36头体重在3.6 kg的7日龄仔猪进行研究。试验1选取144头初生重为0.8~1 kg的仔猪并随机分为3组,分别为对照组(仔猪哺乳期由母猪哺乳),A代乳品组(仔猪额外补饲A代乳品至断奶),L代乳品组(仔猪额外补饲L代乳品至断奶),每组4窝,每窝12头,每窝仔猪由1头1胎长大二元母猪哺乳。试验2选取96头初生重为0.8~1 kg的仔猪并随机分为2组,分别为灌服组(仔猪出生后3 d内每天灌服A代乳品2次,10 mL/次)和对照组(仔猪整个哺乳期由母猪哺乳),每组48头。试验3选取36头7日龄平均体重为3.6 kg的健康仔猪,随机分成3组,每组12头,分别为对照组(仔猪继续由母猪哺乳)、处理1组(饲喂A代乳品)和处理2组(饲喂L代乳品)。试验1结果显示,与对照组相比,补饲A代乳品可显著提升仔猪21日龄断奶体重及增加大于5kg断奶仔猪比例,但补饲L代乳品对仔猪增重无显著提升。试验2结果显示,灌服A代乳品对仔猪存活率和21日龄体重与对照组相比无显著差异。试验3结果显示,仔猪在7~21日龄仅饲喂A代乳品全部存活,但体重低于对照组0.8kg,仅饲喂L代乳品的仔猪失重明显。经济效益分析表明,至21日龄时,补饲A代乳品组每头猪比对照组多获利33元,相对利润提高了15%。
