家蚕对颗粒人工饲料的摄食性及若干物质添加效果的研究

研究结果表明 :家蚕对颗粒人工饲料的嗅觉反应和摄食反应与蒸煮切片饲料无明显差异 ,具有良好的适口性 ;饲料含水量和光照条件对摄食性有显著的影响 ;颗粒人工饲料中添加适量肌醇可提高小蚕的摄食性 ,促进生长发育 ,但添加VC、VB混合物和蔗糖 ,均无明显效果     

公开发行期刊封面标识规范的调查与研究

研究发现,一些期刊一号多刊违反了一号一刊的规定,未对新增期刊申请新刊号,为逃避新闻出版署的检查,把频次标识为ⅹ月上旬、ⅹ月上半、A、下半月刊等形式,而不按实际发行情况标识旬刊、半月、月刊等形式,以及以月代期。一些期刊出版不遵守封面标识的有关规定,刊名不突出,或作夸大宣传,误导读者,外文刊未标识中文刊名。刊期标识也未遵循有关规定,较多期刊以月代期或不标识刊期;较多的期刊对月份的标识执行不力,未标识月的高达29.6%;对卷号的标识仅19.4%;部分期刊以总刊期代替刊期、卷号、年份、月份、频次。频次的标识,按发行实际正确标识的仅14.8%。标识的数字标准还有待统一,有标中文的和外文,而不是阿拉伯数字。调查的结果表明,期刊封面标识出版的有关规定执行并不乐观,还需要共同努力,提高期刊的综合出版质量。

油气输送管道用钢管标准的发展历程及趋势

为保证油气管道工程用钢管标准的先进性和适用性,跟踪研究了国内外油气输送钢管的基础标准、具体工程的管道技术条件及通用管材技术条件的最新发展,并分析了其特点、关系及差异,提出了改进建议。研究表明:基础标准发展变化快,内容系统,适用范围广,但指标低且不具体;重要的油气管道工程必须在基础标准的基础上,针对工程特点,提高或补充相关技术要求,制定具体工程的管材技术条件;通用管材技术条件是基于基础标准补充制定的,但不针对具体管道工程,需要结合具体管道工程给出钢管数据单,确定必要的技术指标并补充技术要求。     

代森锰锌液相色谱法成功晋升为CIPAC方法的历程与启示

由利民化学有限责任公司自主研发的代森锰锌液相色谱分析方法,历时4年,终于在2019年德国布伦瑞克召开的第63届国际农药分析协作委员会(CIPAC)年会上顺利通过答辩,成功晋升为CIPAC方法。本文对此过程进行了总结梳理,以为我国农药标准方法走向国际提供借鉴。     

肉牛引进过程的操作技术规范

肉牛购进过程中存在的实际问题,可能给养牛企业和养牛户造成极大的损失。本文分别从购进牛只的选购目标、健康状况、饲养方式及疫病监测方面提出具体措施;新购牛在当地先需要一个隔离稳定观察期,并做好运输前各项准备工作;提出在运输环节中,对人员、车辆、消毒、草料及饮水准备,饲喂细节、抗应激处理、装车密度、运输过程中的注意事项等;运到后圈舍消毒、隔离观察、饲喂和饮水的过渡方法,强化免疫接种,等待牛群稳定后才可进入繁育或者育肥环节。     

Suitability of two agglomerated commercial microdiets for rearing larvae of different strains of Coregonus lavaretus under cold‐water conditions

The suitability of two agglomerated commercial microdiets (“Gemma micro^®” and “O.range^®” from now on called diet A and diet B) as a starter feed was tested on larvae of European whitefish (Coregonus lavaretus). Two strains (Baltic and Alpine) were tested in a 60‐day experiment under ambient cold‐water conditions (average 7.6 ± 1.9°C). The experiment was carried out in 400‐L PVC tanks with a stocking density of 5,000 larvae per tank. Samples were removed weekly to determine growth, survival and feed acceptance, in addition to water quality. Striking differences between the feeds and different strains were observed. For one diet, growth and survival were distinctively higher in strain 1 compared to strain 2, where it was invariably low with both diets. For the second diet, growth and survival in strain 1 were also low and similar to strain 2. Feed acceptance in strain 1 was found higher compared to strain 2. Final weights were significantly different with strain 1 being heavier; however, in terms of relative growth rate, no differences between strains were found. Strong differences in the performance in terms of growth, survival and feed acceptance of different strains of European whitefish became apparent. Furthermore, the rearing of larvae exclusively on standard agglomerated commercial microdiets under cold‐water conditions is possible, but not every microdiet is suitable.

Goat milk acceptance and promotion methods in Japan: The questionnaire survey to middle class households

A consumer questionnaire conducted with the purpose of ascertaining the acceptability of goat milk and related products in Japan was carried out on 345 guarantees of Nippon Veterinary and Life Science University in December 2006. 275 effective responses (79%) representing middle class urban households were returned. The results revealed that (1) 30% of respondents have experienced drinking goat milk and only 10% are aware of the current retail situation of goat milk and related products; (2) over 70% of goat milk drinkers raised goats by hand at some point in their past and their first experience drinking goat milk was in infancy; (3) those with experience in drinking goat milk expressed a vague evaluation and minimal understanding of drinking goat milk; (4) respondents who were inexperienced goat milk drinkers expressed a strong desire to taste and a weak desire to purchase goat milk; (5) respondents expressed low recognition regarding retailed goat milk products, but those who had already purchased goat milk products expressed a high evaluation and strong desire to purchase these products again; and (6) recognition of goat milk characteristics is low, but those with high recognition also rate goat milk highly. Goats are perceived as being 'mild and familiar.' It is necessary for those who manage goat husbandry to present goat milk and related product tasting opportunities to consumers. The key point is to make the functional differences between cow and goat milk clear and present the advantages of goat milk at the fore of this promotion. Goat milk should not be promoted merely as a drink that is similar to cow milk, but must be positioned as a functional drink or health food in order to expand the Japanese goat milk market.     

浅议环保设施竣工验收监测

在环保设施竣工的实际验收监测过程中,因设施运行和样品采集会带来一些系统误差,它远大于验收监测过程中产生的室内外分析误差,严重影响了设施验收后的正常运转。为了消除这些系统误差,提出了一系列的措施：验收前的现场检查和资料收集,注重验收监测方案、监测点位和频次,加强验收期间工况负荷监测,科学解释”达标概念”,深入验收现场,实地监督,严格把握住现场质量验收。
