食品安全问题一直深受重视。一般来说,食品在投入市场售卖之前,相关部门都会对食品安全进行检测,分析比判断食品的安全性与无毒无害性,以此保证食品安全。微量元素作为在食品安全检测对象之一,其同样需要做好准确检验,否则会对食品安全造成影响。本文结合食品安全检测实践,对食品微量元素检验方法进行分析,探讨总结出相关结论,供同行参考借鉴。 相似文献

本研究应用血凝抑制试验(HI),在2005年初,于黑龙江省绥化、海林两地区散养的临床健康的猪、家禽中采集血清样品178份,对其进行了血清学检测,并将获得的血清学检测数据进行了统计学分析。分析结果显示,绥化地区采集的血清样品共计60份,其中家禽中抗H9亚型流感病毒抗体阳性样品24份,占家禽检测总样品数(45份)的53.3%;在海林市地区采集的血清样品共计118份,其中家禽中抗H9亚型流感病毒抗体阳性样品29份,占家禽被检测总样品数(88份)的32.9%。在两地猪群中的血清学检测结果发现,抗H9亚型流感病毒抗体阳性率较高,分别占猪血清检测样品(14/15,19/30)的93,3%和63.3%,两地的畜禽检测中均未检测到H5、H7亚型抗流感抗体。本次试验检测结果表明,在黑龙江省的畜禽养殖中,尤其是猪与家禽当中,存在抗H9亚型流感病毒的抗体,推断可能有该亚型流感病毒的传播;未检到H5、H7亚型流感病毒抗体,在本次检测中可以初步判定在被检测的畜禽当中不存在高致病性禽流感病毒感染与流行。 相似文献

Statistical graphics, and data visualization, play an essential but under-utilized, role for data analysis in animal science, and also to visually illustrate the concepts, ideas, or outputs of research and in curricula. The recent rise in web technologies and ubiquitous availability of web browsers enables easier sharing of interactive and dynamic graphics. Interactivity and dynamic feedback enhance human–computer interaction and data exploration. Web applications such as decision support systems coupled with multimedia tools synergize with interactive and dynamic graphics. However, the importance of graphics for effectively communicating data, understanding data uncertainty, and the state of the field of interactive and dynamic graphics is underappreciated in animal science. To address this gap, we describe the current state of graphical methodology and technology that might be more broadly adopted. This includes an explanation of a conceptual framework for effective graphics construction. The ideas and technology are illustrated using publicly available animal datasets. We foresee that many new types of big and complex data being generated in precision livestock farming create exciting opportunities for applying interactive and dynamic graphics to improve data analysis and make data-supported decisions. 相似文献

通过对高寒山区自然演替的逸生种扁穗雀麦(Bromus cartharticus)单株性状与种子产量的相关通径分析发现,多元决定系数∑d=0.957 6,表明影响种子产量的主要性状均包括在内,结实率、花序种子数和千粒重是影响种子产量的主要性状。分析得出种子产量最优多元回归方程为:y=-453.07+0.958 7x7(花序种子数)+0.342 7x8(千粒重)+0.510 5x9(结实率)。在生产实践中,提高结实率、花序种子数和千粒重是提高扁穗雀麦种子产量的有效途径。 相似文献

Preliminary observations on the effects of Meloxicam in a new model for acute intra-articular inflammation in dogs 总被引:1,自引:0,他引:1
The effects of intra-articular injection, on two occasions, 3 weeks apart, of the contrast agent Urografin on the cytological and biochemical characteristics of synovial fluid (SF) were examined in two studies in dogs. The first study provided baseline data in two non-medicated dogs. The second study used a cross-over design whereby 4 dogs received a 7-day oral treatment with either a placebo or meloxicam (0.2 mg/kg body weight daily) with a washout period of 3 weeks, in order to determine the effect of this new non-steroidal anti-inflammatory drug (NSAID) on the response to Urografin injection. SF samples were collected under general anaesthesia prior to and at 24 and 72 h after each Urografin injection. The volume, relative viscosity, white blood cell count and concentrations of protein, lactate dehydrogenase (LDH) and hyaluronic acid of these samples were determined.The results from both studies indicate that intra-articular injection of Urografin provoked a mild local transient inflammatory response, the most dramatic evidence of which was an increase in the white blood cell count in the SF after 24 h. In the second study, comparison of the synovial fluid measurements of the placebo-treated dogs at 24 h after Urografin injection with those prior to injection revealed significant increases in SF volume, white blood cell count, protein concentration and LDH activity and a significant reduction in relative viscosity. At 72 h after injection, only the white blood cell count and relative viscosity were significantly different from the pre-injection values. All of these measurements were, however, associated with high coefficients of variation, which must be taken into account in assessing the usefulness of the model for drug-testing purposes. Nevertheless, the administration of meloxicam significantly reduced the SF volume and white blood cell count at 24 h relative to the effects of concurrent placebo treatment. The general health status of the animals was not disturbed at any time as assessed by clinical and haematological observations. No adverse reactions were observed.Abbreviations LDH
