早期营养补充对肉仔鸡生长性能的影响

饲料与畜牧（新饲料） 2008年第8期 60-60页

作者：陈小莺 henderson S.N. Vicente J.L. Pixley C.M. h.rgis B.M. Tellez G.

根据商业行业的做法，雏鸡从实际孵化到安置一般需要72h.已有记录显示，如果延迟开饲和饮水的时间，会导致感染病原的几率增加、体重减轻、重量收益降低。通过7次试验，比较当雏鸡置于24h.仿真环境中，日粮中添加“EarlyBird”（EB；S... 详细信息

根据商业行业的做法，雏鸡从实际孵化到安置一般需要72h.已有记录显示，如果延迟开饲和饮水的时间，会导致感染病原的几率增加、体重减轻、重量收益降低。通过7次试验，比较当雏鸡置于24h.仿真环境中，日粮中添加“EarlyBird”（EB；Sigrah.Zellet，LLC．）和不添加的差异。每次试验所用的肉仔鸡都来源于同一批商业孵化，颈部标记、单独称重，随机放于可装100只鸡的箱子里。处理组的雏鸡饲喂2g／只的EB。在接下来的24h.雏鸡单独称重、自由采食和饮水。

桡骨远端骨折是成人常见的一种骨折.绝经期后的妇女最多见(男∶女=1∶8).受伤原因多为手掌撑地时的撞击伤.随骨质疏松程度、暴力大小和方向及手位置的不同而产生各种类型的骨折.其中桡骨远端关节外骨折即A2和A3型(AO分类法,相当于Colles骨折)约占50%.对A2和A3型骨折一般采用手法复位,有时悬挂牵引后再石膏绷带固定.不稳定性骨折加经皮克氏针固定.腕关节制动4～6周.长期制动和创伤导致的关节僵硬须做医疗体操强化治疗. 为了使腕关节至少能屈伸活动,h.fmann发明了一种活动性手外固定器,可使活动范围达到约30°.外固定器的活动轴须与腕关节的活动轴一致,以避免功能锻练时产生继发移位. 本研究的目的是在许多医院现有器械的基础上发展一种活动时能保持稳定不跨腕关节的系统 .我们采用AO的小型外固定器.

A search.for th. rare decays W^(+)→D_(s)^(+)γ and Z→D0γis performed using proton-proton collision data collected by th. Lh.b experiment at a centre-of-mass energy of 13TeV,corresponding to an integrated luminosity of 2.0fb−*** significant signal is observed for eith.r decay mode and upper limits on th.ir branch.ng fractions are set using W^(+)→D_(s)^(+)γ and Z→μ+μ−decays as normalization *** upper limits are 6.5×10^(−4) and 2.1×10^(−3) at 95% confidence level for th. W^(+)→D_(s)^(+)γ and Z→D^(0)γ decay modes,*** is th. first reported search.for th. Z→D^(0)γ decay,wh.le th. upper limit on th. W+→D+sγbranch.ng fraction improves upon th. previous best limit.
