酶制剂在青贮饲料中的应用效果及其发展趋势 总被引:3,自引:0,他引:3
酶制剂作为饲料添加剂,已成为遍及世界的趋势。酶制剂的研究与生产,国外从上世纪末就开始了,1894年日本的高峰让吉用米曲霉固体培养了“高峰淀粉酶”(Takadisatase)作为消化药物。二次大战后,随着抗菌素工业的发展,酶制剂工业也迅速兴起。本世纪的80年代,世界发达国家的酶制剂生产企业就有70余家。近年来,我国酶工程及酶工程技术的研究发展也很快,初具规模的酶制剂生产厂家 相似文献

The modern discipline of molecular biology is gaining increasing relevance in the field of veterinary medicine. This trend must be reflected in the curriculum if veterinarians are to capitalize on opportunities arising from this field and direct its development toward their own goals as a profession. This review outlines current applications of molecular-based technologies that are relevant to the veterinary profession. In addition, the current techniques and technologies employed within the field of molecular biology are discussed. Difficulties associated with teaching a subject such as molecular biology within a veterinary curriculum can be alleviated by effectively integrating molecular topics throughout the curriculum, pitching the subject at an appropriate depth, and employing varied teaching methods throughout. 相似文献

In this paper, we discuss the advantages and disadvantages of various approaches of teaching veterinary parasitology, including the disciplinary, the problem-oriented and combined approaches. In the disciplinary approach, parasitology is taught in the classical manner as a coherent subject, covering parasite morphology, biology, molecular biology, epidemiology, pathology, immunology, clinical manifestation, diagnosis, therapy, control, and prevention. Problem-oriented teaching approaches the subjects starting from diseases in animal species or from organ systems or other objectives (e.g. food safety); it also tackles training of skills for problem solving and self-learning. Combined approaches include elements of the disciplinary approach and those of other methods. A combined approach of teaching veterinary parasitology, including basic disciplinary teaching of at least 70-90 h, and additional problem-oriented education, was recently proposed in a resolution by the World Association for the Advancement of Veterinary Parasitology [WAAVP News Lett. 5 (1) 3-4]. In 1999, a new curriculum has been established at the Faculty of Veterinary Medicine, University of Berne, originally planned as a combination of organ-focused and problem-based approach. This model was soon identified to cause problems in teaching some disciplines, including infectious diseases. Conversely, the short-term experiences with this combined approach also confirmed some advantages of problem-oriented teaching in other, mainly clinical domains. Nevertheless, closer interdisciplinary contact and collaboration--especially in elective teaching--was enforced between paraclinical and clinical teaching by reforming the curriculum. However, it turned out that large student numbers in relation to the resources of manpower, rooms and finances limited the workability of the curriculum. Therefore, further and probably continuous improvement of the curriculum is necessary. 相似文献
