对小麦高产理论的探讨

当前小麦高产品种的育种目标定为9000～12000kg／hm^2，以光合生产潜力分析能够成功，采用扬守仁先生育种实践推出的5分制打分法，对小麦品种产量结构分析得出：加强株型选择，提高单株生产力是小麦高产育种的主要途径。     

基于河岸带植物多样性的河流健康评价——以柏条河-府河河段为例

基于河流健康评价目的,将柏条河-府河河段划分为上游、中游、下游3个区域针对河岸带植物多样性进行多层次调查。在多个指标构建的评价系统中对各河段进行评分,上游、中游和下游河段得分分别为72.7分、59.1分和59.3分。评分结果直观反映出柏条河-府河不同河段河岸带植物多样性的状况。依据调查结果为各河段维持和提升植物多样性、河流健康提出了管理措施与建议。     

土地整理项目利益相关者界定与分类研究

通过问卷调查法、统计分析法、多维评分法等方法对土地整理项目的利益相关者进行界定和分类,确定了25种利益相关者,将其分为3类:核心利益相关者,包括县级政府、县级国土部门、县级土地整理中心、农民集体经济组织、农户、乡级政府、村民委员会;中间利益相关者,包括中央政府、国土资源部、国土资源部土地整理中心、省级国土部门、省级土地整理中心、县级财政部门、县级水利部门、政府监察部门、政府审计部门、社会公众;外围利益相关者,包括县级环保部门、县级农业部门、监理机构、设计机构、工程承包商、设备供应商、材料供应商、招标代理机构。项目管理者应当重视利益相关者的利益诉求,并采取不同的应对策略。     

脑钠肽水平与急性心肌梗死面积关系的研究

目的探讨血浆脑钠肽（BNP）水平与急性心肌梗死（AMI）面积的关系.方法以86例AMI患者为观察对象,根据梗死相关部位的不同将其分为前壁心肌梗死组57例,下壁心肌梗死组29例.结果 Aldrich公式法预测的心梗面积与治疗前BNP水平显著相关,而QRS积分法预测的心梗面积与治疗后BNP水平显著相关（r分别为0.889,0.872,P〈0.01）;前壁心肌梗死组治疗前BNP水平高于下壁心肌梗死组.结论 BNP与AMI的面积有相关性,BNP越高,心肌梗死的面积越大,BNP可能为急性心肌梗死初期的危险分层提供重要依据.

Should We Agree to Disagree? An Evaluation of the Inter-Rater Reliability of Gait Quality Traits in Franches-Montagnes Stallions

Gait quality, that is, the way horses move according to functional and aesthetic principles, englobes many traits that are scored by experts during breeding competitions. The experts can score a trait on a subjective valuating (SV) scale or on a linear profiling (LP) scale representing the biological extremes of the population. However, the reliability of the appraisal of gait quality traits has not been extensively evaluated. In this study, seven breed experts appraised the walk and trot quality of 24 Franches-Montagnes stallions presented in hand on a sand track. Inter-rater reliabilities of six traits (five SV and one LP) at the walk and eight traits (five SV and three LP) at the trot were estimated with intraclass correlation coefficients (ICCs). The inter-rater reliabilities were poor (ICC < 0.50). The scale anchoring varied between experts, and the variance of scores was low. There were no systematic differences in inter-rater reliability between LP and SV traits. Future studies should determine whether the inter-rater reliabilities may be increased by a more precise definition of the scores within each trait to improve the absolute agreement between experts, by a more uniform scale anchoring between experts, and by decreasing the number of scale items. However, considering the inherent limitations of the human eye in observing high-speed movement, the use of a field-applicable kinematic measurement system may support breeding experts in the appraisal of gait quality traits in the future.     

A scoring system for risk assessment of the introduction and spread of bovine viral diarrhoea virus in dairy herds in Northern Italy

To support a voluntary disease control program, this study aimed to develop an integrated scoring system for the risk assessment of bovine viral diarrhoea virus (BVDV) infection in dairy herds in Northern Italy. Sixty-two dairy herds were classified according to their BVDV serological status. Farmers were interviewed using a questionnaire on potential BVDV risk factors. Scores were used to define risk levels for factors related to (1) BVDV introduction (through livestock trade, attendance of animals at shows/exhibitions and grazing common pasture), (2) within-herd spread of BVDV and (3) the results of initial serological testing. The calculated odds ratios were significant for all categories, except for livestock trade. The application of the screening test, the questionnaire and the related risk assessment showed this to be a practical approach to predicting BVDV herd status.     

止泻草药预防仔猪腹泻及对生产性能的影响

选取对大肠杆菌和沙门氏菌抑菌效果明显的4个贵州草药配方,对断奶仔猪进行1个月的饲养试验。采用模糊评分法,对平均净增重、增重率、料肉比、生长每㎏肉的饲料成本、腹泻频率、粪便黏稠频率、精神萎糜频率、治疗注射频率和不采食频率共9项指标进行综合评价,结果表明:配方1能明显提高饲料利用率,节约饲料成本,能有效预防仔猪腹泻;配方3能增进食欲,健康状态最好;配方1和配方3在仔猪饲养中效果最好,可实现无抗饲养。
