Abstract:

本试验旨在研究阴外动脉灌注脂多糖(LPS)对泌乳奶牛乳成分、乳脂合成前体物和脂肪酸组成的影响。选用6头处于泌乳期第(185±30)天、体重(576±36)kg的经产的荷斯坦奶牛,随机分成2组。采用交叉试验设计,试验组阴外动脉灌注LPS(EscherichiacoliO111∶B4,0.01μg/kgBW),对照组灌注生理盐水。试验分2期,每期试验7d,2期间隔14d。结果表明:泌乳奶牛干物质采食量受LPS影响差异不显著(P>0.05);LPS显著提高乳中乳蛋白率(P<0.05),对乳脂率无显著影响(P>0.05);LPS极显著降低血浆中乳脂合成前体物非酯化脂肪酸的含量(P<0.01),β-羟丁酸含量呈先降低后升高的趋势(P>0.05);LPS不同程度地降低了乳脂中饱和脂肪酸(P>0.05)和短链脂肪酸(P>0.05)的含量,提高了乳脂中不饱和脂肪酸(P>0.05)和中长链脂肪酸(P>0.05)的含量,并影响脂肪酸的去饱和作用。结果提示,LPS是诱发乳脂合成发生变化的主要激发因子之一。
