SSR标记分析国家油菜区试品种的特异性和一致性

 【目的】分析中国油菜区试品种的特异性、一致性和稳定性,为新品种审定和品种权保护提供科学依据。【方法】以近年参加中国冬油菜区域试验的89个品种为试验材料,利用筛选确定的15对较好的SSR引物开展品种的特异性和一致性分析。【结果】共获得42个多态性标记。遗传聚类、主成份、分配试验和AMOVA分析结果表明：42个标记能够将89个品种完全区分开;同一个育种单位选育的品种其遗传基础相近,而不同地区或育种单位选育的品种其遗传背景相差较大,揭示的遗传结构与品种系谱来源相吻合;以遗传距离0.1为划分标准,75％的供试品种具备特异性;分配试验中,大部分单株都能正确的分配回到原来的品种,少数品种的单株正确分配率较低,品种一致性差;品种在供种年份间差异不显著,其一致性较好,而在同一年份的品种间差异极显著,其特异性较高。【结论】除少数品种外,大部分品种都具有很高的特异性和一致性;SSR标记是适合于开展油菜品种DUS测试的鉴定技术。

辽宁省基层畜牧兽医机构队伍改革情况调查

为了解基层畜牧兽医机构队伍改革情况,对2015—2020辽宁省畜牧兽医机构队伍建设情况进行了综合分析。辽宁省机构改革后,市、县、乡三级畜牧兽医机构以及工作人员、专业人员及村级动物防疫员等的数量均呈下降趋势,基层动物防疫体系和体制机制受到冲击。建议在深化兽医机构改革中坚持机构"瘦身与健身"相结合,体制创新与继承相结合,改革目标与实效相结合,以期为基层畜牧兽医机构队伍建设提供参考。     

Psychological well-being of Australian veterinarians

Objective   To use established psychological scales to measure levels of distress, anxiety and depression in veterinarians, and compare these levels between different veterinary subgroups and other professional groups.
Methods   A cohort of veterinarians was identified through contact with veterinary schools in Australia. Participants completed a self-reporting questionnaire that included queries about general health and demographics, psychological well-being, job-specific perceptions of health, dispositional characteristics and social support.
Results   Of the 2125 respondents who completed the psychological questionnaire, approximately one-third reported poor psychological health. Increasing age, increasing time in current job, increasing years since graduation and male gender was associated with fewer signs of distress, anxiety and depression. Compared with the general population, veterinarians experienced more negative emotions at work, but were similar to other professional groups.
Conclusions   Poor psychological health is common in the profession and professional veterinary bodies may wish to consider providing training in dealing with work-related distress, anxiety and depression.     

Musculoskeletal disorders and psychosocial risk factors among veterinarians in Queensland, Australia

Objective   Although musculoskeletal disorders (MSD) represent one of the most important occupational health issues in contemporary society, few studies have specifically investigated this problem among veterinarians.
Design   An anonymous questionnaire survey mailed to all veterinarians registered with the Veterinary Surgeons Board of Queensland during 2006.
Results   Almost two-thirds of respondents (63%) had experienced MSD of the lower back, 57% had experienced neck-related MSD, 52% had experienced shoulder-related MSD and 34% had experienced MSD of the upper back during the previous 12 months. MSD was statistically correlated with a range of psychosocial factors, including stress associated with career structure, time pressures, client's attitude, lack of recognition by the public, lack of recognition by colleagues, lack of understanding from family or partners and work stress because of insufficient holidays each year.
Conclusion   Overall, this study has demonstrated significant correlations between MSD and psychosocial risk factors among a large cohort of veterinarians, apparently for the first time in the published literature. The results also suggest that personal and workplace issues may contribute more to the development of MSD among veterinarians than many of the previously recognised ergonomic risk factors.
