全价配合饲料的品质取决于饲料原料质量、饲料配方水平以及饲料加工质量.品质差的原料可以通过调整配方的方式变废为宝;通过配方原料结构的调整,可以满足不同加工工艺条件的要求,因此配方是影响全价配合饲料品质的关键. 相似文献

信鸽界多年来总结出的最精辟的三字经就是“种、养、训”。“种”在前，“训”在后，“养”居中。在三字经中“养”不但起承前启后的桥梁作用，而且“种”中有“养”，“训”中也有“养”，“赛”更离不开“养”。“养”始终贯穿于培养赛鸽的各个环节，养功的好坏直接关系到赛鸽的成败。 相似文献

禽流感疫苗抗原浓缩工艺的研究 总被引：1，自引：0，他引：1
为了提升禽流感疫苗中的抗原效价,本研究采用密理博公司的切向流超滤系统,选用不同孔径的超滤膜和浓缩倍数对禽流感病毒(H9N2亚型,HP株)进行浓缩,观察HA和EID50的变化.结果显示:膜包孔径越大,病毒透过越多,但膜包孔径过小,浓缩时间长;随着浓缩倍数增加,HA和EID50均呈正相关增长,但高浓缩倍数耗时较长.说明禽流感疫苗生产中应根据抗原相对分子质量、HA、EID50和生产效率选择合适的超滤膜孔径和浓缩倍数. 相似文献

A quantitative method for the informative evaluation of teaching activities was devised using a survey from 33 experts. It is based on an evaluation, by students and two peers, of the four steps of the instructional methodology: analysis of training needs, statement of learning objectives, delivery of teaching session, and testing of student performance. Faculty evaluation is optional, and results are strictly confidential. Results of a three-year trial of this protocol at the Alfort veterinary school are presented and discussed. Each year the method has been assessed and some changes have been implemented. It is now felt that evaluation questionnaires for lectures and tutorial sessions have been validated, while those for laboratories and clinical teaching have to be tested through a larger number of settings. A the same time, a change from informative to summative evaluation is under consideration. 相似文献

如何开展幼犬的早期培训是繁育员急于解决的问题,作者根据自己的实践总结归纳为以下四招,即"一喊"、"二摸"、"三抱"、"四衔". "一喊"的要领 所谓"一喊"就是在幼犬培训中的叫喊,使75日龄的幼犬适应主人的叫喊,能顺利地走到主人跟前.培训的方法是:首先是引导仔犬出门,让哺乳母犬通过喂奶把仔犬带出犬舍门,经过多次引导后,让仔犬逐渐脱离母犬的带领也能出门. 相似文献

Radiological skills including ultrasonography and fluoroscopy, require a combination of manual dexterity and visuospatial skill to develop competency. The ability to detect veterinary students with an interest in radiology but who are deficient in these skills, may permit more individual adaptations to training programs, allowing for students training in radiology to achieve maximal potential. The objective of this cohort study was to investigate whether innate dexterity and visuospatial skill could be used to predict performance of basic ultrasound and fluoroscopic skills in veterinary students. Fifty veterinary students from the Ontario Veterinary College completed three tests of visuospatial ability, two tests of manual dexterity, a three‐dimensional mouse task, an ultrasound skill‐testing task, and a fluoroscopic skill‐testing task. Students who reported chopstick use completed the non‐dominant hand ultrasound task significantly faster than students who did not (P = 0.001). There was a significant positive association between scores on the Mental Rotations Test and time to complete the non‐dominant hand ultrasound task (P = 0.011) and fluoroscopy task (P = 0.029). No variables were associated with time to complete the dominant hand ultrasound task. The results of this study suggest that visuospatial skill, as assessed by the Mental Rotations Test, is a better predictor of baseline ultrasound and endovascular fluoroscopy skill than dexterity, with the exception of reported chopstick use, in veterinary students. Visuospatial skills can be developed and may be useful to include in the veterinary curriculum for students that are deficient, or students entering a field such as diagnostic imaging. 相似文献
