| 1 | 提高母猪妊娠后期和哺乳期日粮能量浓度对其生产性能、仔猪活力和后代终生生长的影响(下)显示文摘人们对高产母猪的选育,导致每窝活产仔数显著增加,但是随之而来的仔猪活力和生长性能会因此降低。为了增强仔猪活力和提高生长性能,提高母猪哺乳期能量摄入越来越重要。研究旨在探索提高哺乳期母猪日粮能量(DE)浓度对母猪体重、背膘厚、乳成分及其后代仔猪活力和生长的影响。在妊娠108 d时将妊娠母猪(N=100;大白×长白)随机分配饲喂4种能量浓度日粮(消化能,DE,MJ/kg)直到再次配种:13.8(LL)、14.5(L)、15.2(H)、15.9(HH)。所有日粮均含有1.2%总赖氨酸。妊娠108 d和断奶(哺乳期第26天)时采集血样,哺乳期采集初乳(0 d)和常乳(14 d)。每天记录母猪哺乳期采食量。仔猪出生时记录每窝(总活)产仔数、仔猪初生重、宫内生长受限(IUGR)特征和肌张力。在出生时和出生后24 h记录仔猪鼓膜耳温(TEMP)。在后代猪第1、6、14、26、33、40、54、75和141日龄时称重。后代猪于断奶后(PW)饲喂标准谷物基础日粮。后代猪屠宰时(141日龄)记录胴体数据。HH母猪的哺乳期消化能摄入高于其他处理组(P<0.01)。初乳和常乳成分以及哺乳期采食量不受日粮处理影响。各处理组间的每窝产仔猪数和仔猪初生重相近。与其他处理组相比,LL母猪的后代表现出更多的IUGR特征(P<0.01),而HH母猪的后代表现出更好的肌张力(P<0.01)。与HH母猪的后代仔猪相比,LL母猪(P<0.01)和H母猪(P<0.01)的后代具有更高的24 h TEMP。H母猪断奶仔猪数高于L母猪(P<0.05)和HH母猪(P<0.01),而L母猪断奶仔猪窝重低于H母猪(P<0.05)和LL母猪(P<0.05)。断奶后仔猪生长不受日粮各处理影响。高DE日粮提高母猪能量摄入水平,但并不抑制食欲。饲喂HH日粮提高了仔猪出生时肌张力,而饲喂H日粮提高每窝断奶仔猪数。此次研究观察到仔猪活力的其他特征和断奶前窝生长性能结果互相矛盾。 | 何颖(编译) Rooney H B O’driscoll Keelin O’doherty John V | 2020 | 猪业科学2020，37，9： | 5 |
