高校图书馆精益管理研究

将“精益管理思维”应用于高校图书馆管理，试图从新视角为解决诸如图书馆利用率不高、图书经费不足及树立图书馆形象等实际问题，从而顺应社会及时代的发展趋势。     

提高牦母牛繁殖性能的研究

采用不同剂量生殖激素处理3.5岁的青年牦母牛,结果发情率提高5.84和23.26个百分点,繁殖率分别提高34.69和41.21个百分点。采用不同剂量生殖激素处理和怀孕牦母牛围产期补饲的措施,促进产后成年牦母牛发情配种,结果发情率分别提高42.42,54.67和37.51个百分点,繁殖率提高43.93,48.48和20.10个百分点。生殖激素处理和围产期补饲对提高牦牛繁殖性能有较大的促进作用,高剂量生殖激素的促进效果较明显。     

补饲非蛋白氮补充料对放牧牛群生产性能的影响

本试验旨在研究补饲非蛋白氮（NPN）补充料对放牧牛群生产性能的影响。试验在春末夏初放牧前,选择30头9~10月龄、体重150~170 kg的中国西门塔尔太行类群小公牛,分为对照组、试验1组和试验2组,进行放牧加补饲试验。试验1组日补饲玉米粉1.0 kg;试验2组在试验1组的基础上增补NPN补充料0.25 kg。进行了为期100 d的放牧补饲效果试验。结果表明,对照组、试验1组、试验2组日增重分别为0.622、0.839和1.051 kg。试验1组比对照组日增重提高217 g;试验2组比对照组和试验1组日增重分别提高429和212 g。3组间增重差异显著。因此,北方山坡草地放牧牛群补饲少量精料效果明显,同时,补喂少量NPN补充料经济效益更为显著。     

Successful drug development despite adverse preclinical findings part 1: processes to address issues and most important findings

Unexpected adverse preclinical findings (APFs) are not infrequently encountered during drug development. Such APFs can be functional disturbances such as QT prolongation, morphological toxicity or carcinogenicity. The latter is of particular concern in conjunction with equivocal genotoxicity results. The toxicologic pathologist plays an important role in recognizing these effects, in helping to characterize them, to evaluate their risk for man, and in proposing measures to mitigate the risk particularly in early clinical trials. A careful scientific evaluation is crucial while termination of the development of a potentially useful drug must be avoided. This first part of the review discusses processes to address unexpected APFs and provides an overview over typical APFs in particular classes of drugs. If the mode of action (MoA) by which a drug candidate produces an APF is known, this supports evaluation of its relevance for humans. Tailor-made mechanistic studies, when needed, must be planned carefully to test one or several hypotheses regarding the potential MoA and to provide further data for risk evaluation. Safety considerations are based on exposure at no-observed-adverse-effect levels (NOAEL) of the most sensitive and relevant animal species and guide dose escalation in clinical trials. The availability of early markers of toxicity for monitoring of humans adds further safety to clinical studies. Risk evaluation is concluded by a weight of evidence analysis (WoE) with an array of parameters including drug use, medical need and alternatives on the market. In the second part of this review relevant examples of APFs will be discussed in more detail.

张家川县放牧补饲条件下的肉牛增重试验

经对12—18月龄西杂一代阉牛10头,采取以放牧为主、夜间补饲,育肥90d,试验表明试验组平均总增重86.4±44.4kg,平均日增重0.96±0.69kg,12月龄的6头日增重1kg,育肥效果显著。

舍饲和放牧BMY牛血液生化指标比较

[目的]为了解不同饲养管理条件下,BMY牛血液生化指标的变化情况,以到达补充BMY牛的基础性资料,为BMY牛的人工饲养、疫病防治提供理论依据的目的。[方法]采用试剂盒对20头不同饲养管理条件下的BMY年母牛的血液生化指标进行了检测。[结果]显示:舍饲牛的STB、A/G、LDL、GLU、Crea和P等指标显著高于放牧组,放牧牛的GLO、ALT、AST/ALT、GGT和TG等指标显著高于舍饲牛(P<0.05),TP、HGB、ALP、BUN、URIC、T-CHOL、Ca、HDL在两组间差异不显著(P>0.05),舍饲牛的血液生化指标的变异系数要明显小于放牧牛。[结论]舍饲BMY牛的血液生化指标明显要优于全放牧条件下的BMY牛。
