| 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 |
| 2 | 蛋白酶和木聚糖酶对育肥猪的生长性能、营养消化率以及粪便气味的影响显示文摘菜籽粕(RSM)和小麦干酒糟及其可溶物(DDGS)作为副产物可应用到猪的日粮中。然而,与小麦和豆粕型日粮相比,RSM和DDGS中含有较高的非淀粉多糖(NSP),其可限制猪对日粮的有效利用。采用2×2因素试验设计研究生长育肥猪饲粮中添加木聚糖酶(0和200mg·kg-1)和蛋白酶(0和200mg·kg-1)对其生长性能、胴体品质、表观回肠消化率、全消化道养分消化率及粪便气体排放的影响及两种酶之间的相互作用。试验1,对猪的生长性能进行评估。将体重为34.2±2.1kg的育肥猪128头随机分配到4个处理组:以DDGS(300g·kg-1)和RSM(210g·kg-1)的基础日粮;基础日粮中添加蛋白酶200mg·kg-1;基础日粮中添加木聚糖酶200mg·kg-1;基础日粮中添加蛋白酶200mg·kg-1和木聚糖酶200mg·k-1。试验1中,在生长育肥-出栏期间(0~出栏),日粮中添加蛋白酶的试验猪较不添加蛋白酶的试验猪相比具有较低的平均日增重(ADG)(P〈0.001)。生长阶段(0—28d),蛋白酶和木聚糖酶对猪的日均采食量(ADFI,P〈0.01)和体重(BW,P〈0.01)的影响存在相互作用。在育肥阶段(28d~出栏),日粮中添加蛋白酶和木聚糖酶的试验猪与仅添加一种没酶的试验猪相比具有较低的ADFI和BW。然而,蛋白酶和木聚糖酶的相互作用在生长期间(0~28d)内并不显著。试验2,选择体重78±2.3kg公猪24只,将其置于代谢笼中进行代谢试验,试验期间按照试验l中的日粮进行饲喂。木聚糖酶和蛋白酶对总能(GE)中的AID存在相互作用(P〈0.05)。与对照组相比,饲粮中添加蛋白酶可以增加GE中的AID,但饲粮中添加两种酶时可降低GE中的AID。饲粮中添加木聚糖酶交不添加木聚糖组相比,猪粪便的臭气排放量降低(598和1306OuE/m3;P〈0.05)。研究表明,蛋白酶可提高GE的AID;木聚糖酶可以减少粪便异味的排放,然而当生长猪育肥以RSM和DDGS为基础饲粮时,两种酶均不能提高其生长性能。 | O'Shea C J Mc Alpine P O Solan P Curran T Varley P F Walsh A M Doherty J V O | 2014 | 饲料博览2014,0,10: | 4 |
