751-6001-00LForum: Livestock in the World Food SystemW2 credits1SM. Kreuzer, S. M. Bernal Ulloa, R. Mandel, E. Mandel, S. Neuenschwander
AbstractThis forum is a platform for the critical reflection of highly relevant topics of livestock in the frame of the world food system comprising issues from basic knowledge to acceptance in society. The exchange is operated by scientific writing and presentation.
ObjectiveIn the Forum "Livestock in the World Food System", a topic of significance for livestock agriculture is selected by the students and subsequently dealt with from various angles (from scientific basis to production systems, environmental aspects and to the acceptance by society). The students learn to present a scientific subject in writing and orally to an audience and to defend the presentation in a discussion.
ContentThe Forum "Livestock in the World Food System" will take place in blocks of 2 hours each. Once the general topic has been selected, it comprises two elements:

Element 1. Oral Presentation: The students form small groups and are lecturers. There are chair persons (moderators) from outside of these small groups and they also head the discussion. The remaining students and lecturers are the audience.

Element 2. Scientific writing: Option 1: preparation of a short scientific type of paper from a result table offered by the lecturers; Option 2: preparation of an abstract with limited word count from a scientific paper; Option 3: writing of a critical review of a paper. The students have to select 2 of the three options each. There will be a discussion be a discussion in small groups at two dates.

Introductions to both forms of presentation will be offered by lecturers.
The preparation of the oral and written presentations takes place to a small part during the 2-h blocks and mainly outside of this time.
Lecture notesno scriptum
Prerequisites / NoticeRequirements for allocation of the two credit points:
- Theatre presentation (with handout) at the forum
- Delivery of written documents of sufficient quality
- Active participation during the presentations by the other participants

AbstractMethods for analysing livestock data, in particular for the estimation of breeding values: principles of selection index, introduction to BLUP, application of common models used, relationship matrix, methods for the estimation of variance components, basics of breeding programs. The material will be illustrated via exercises and assignments.
ObjectiveThe students are able to set up design matrices, the relationship matrix and its inverse as well as the Mixed Model equations to estimate BLUP breeding values for smaller examples.
Content- Selection index (various sources of information, one trait, multiple traits)
- Relationship matrix and its inverse
- BLUP: one trait, repeated observations, multiple traits, economic indices
- Introduction to methods for the estimation of variance components
- Assignments
Lecture notesCopies of the slides are available on the net.
LiteratureTo be announced in the lectures.
751-6501-00LRuminant Science (HS)W+4 credits4GM. Kreuzer, M. C. Härdi-Landerer, R. Mandel, E. Mandel, U. Witschi
AbstractThe course provides the scientific basis of the central aspects of reproduction, husbandry and nutrition physiology of ruminants, and of the implications for animal welfare, product quality, breeding programs, and organic livestock systems. Means of knowledge transfer include interdisciplinary approaches, disciplinary parts, web-based learning and self-study.
ObjectiveAt the end of the course the students are able to apply, by a comprehensive understanding of the underlying mechanisms, their knowledge in various fields of ruminant science. They will be able to develop and recommend best strategies for breeding programs, feed formulation, improving forage quality, increasing animal health and welfare etc. They will be trained to carry out interdisciplinary and disciplinary research at the highest level. The course Ruminant Science (FS) offered in spring has a similar structure but is complementary to this course.
ContentFields (contact hours)
- Introduction: 2 h
- Special topics: 12 h

- Self-study within semester: 30 h (especially preparation for the interdisciplinary courses and the own lecture)
- Self-study in semester break: 38 h
Total: 120 h
Lecture notesDocumentations, links and other materials will be provided at the start of the course
LiteratureInformation on books and other references will be communicated during the course
Prerequisites / NoticeThe specialty of this course is that for the first time the animal science disciplines are unified. This is realised with a particular emphasis on interdisciplinary special topics and new forms of teaching. At the same time the essential basics in the central fields are communicated.

The field of Ruminant Science will also be a part of the spring semester (special topics: Organic Ruminant Systems, Tropical Ruminant Systems, Mastitis; disciplinary courses: Cattle, Sheep and Goat Breeding, Ruminant Diseases and Prophylaxis, Ruminant Nutrition and the Environment). However both courses are organized independently.

Conditions for successful participation: Background on animal science from the Bachelor is desired. In order to attend the Minor in Ruminant Science without any animal science background, a realistic self-assessment concerning the need for additional self-study is recommended (e.g. by choosing an appropriate bachelor course which then may be counted as 'optional courses' in the master). These efforts depend on the extent to which animal science courses have already been attended in the bachelor.

The control of performance will consist of:
- an own lecture
- a final oral examination with focus on comprehension of the fundamental linkages rather than of specific details
751-7211-00LRuminal DigestionW+1 credit1GA. Schwarm
AbstractThis course broadens the knowledge in one of the most important aspects of ruminant nutrition: the microbial digestion in the rumen (and in the hindgut). For a comprehensive understanding of the rumen microbial ecosystem, the mechanisms of nutrient fermentation and the synthesis of microbial protein, thorough basics are provided. Apart from lectures, group and laboratory exercises are included.
ObjectiveThe course enables students to understand in detail how ruminal digestion works and how this knowledge can be applied to design optimal feeding diets using highly fibrous forages and a variety of other feeds. The students also are able to show how to modify the most important rumen microbes beneficially by nutritional means.
ContentStructure of the contact hour part of the course (14 h):

2 h Introduction and blackboard exercise

8 h Basic topics in ruminal digestion, lectures and group exercises:
- Systematics of the microbes involved in microbial digestion
- Measurement of microbial digestion
- Interactions of microbes and epithelium of the digestive tract
- Differences between ruminal and hindgut microbial digestion
- Microbial nutrient degradation and its modification
- Efficiency of microbial protein synthesis
- Manipulation of the ruminal digestion

2 h Laboratory exercise with a rumen fistulated cow and the Rumen Simulation Technique

2 h Final seminar

The non-contact hour part is to comprehend the information given and to prepare either the written report or the oral presentation (cf. "Besonderes")
Lecture notesLecture notes are provided via Moodle.
LiteratureWill be communicated at the start of the course.
Prerequisites / NoticeThe course is a balanced mixture of blackboard exercise, laboratory exercise, group exercise, lecture and student seminar presentation.

AbstractEndokrinologie und Reproduktionsbiologie der Säugetiere und des Menschen (Anatomie, Morphologie, Physiologie, Regelmechanismen)
Die Systematik der Reproduktionshormone und der Hormonrezeptoren wird erläutert, die Wirkungsmechanismen (Bildung; orale Bioverfügbarkeit; Elimination) erklärt. Mit diesen Grundlagen wird das Verständnis der Regulation der Fortpflanzung umfassend erörtert.
ObjectiveDie Studierenden erlangen das grundlegende theoretische Verständnis und Fachwissen zur Endokrinologie der Reproduktion und zur weiblichen und männlichen Reproduktionsbiologie. Sie können darüber hinaus pathologische Situationen (Fortpflanzungsstörungen) und deren vielfältige Ursachen in den physiologischen Kontext einordnen.
