Prerequisites
Have passed at least the first 3 years of the degree. It is recommended that the student review the statistical content taught in Epidemiology and Statistics course (in the second year)
Objectives and Contextualisation
This is an optional subject for the fifth year, where the main objective is to give the Veterinary student the knowledge to be accredited for the D function (Design of Procedures and Projects) established in Royal Decree 53/2013, which refers to the protection of animals used for scientific purposes and where the issues related to the training and training of staff working with experimental animals are regulated. This subject is aimed at all those students who contemplate to work in the research field, and especially to those who wish to continue their education with third cycle studies.
The main focus where the whole subject is based is the application of the principle of 3Rs in the design of procedures and their impact on the experimental data obtained. All the factors involved in the experimental design will be tackled step by step: from the approach of the hypothesis to the choice of the experimental model, the impact of animal welfare and the control of the environmental factors, the choice of the experimental design and the appropriate statistical analysis, and finally the dissemination of results.
The specific training objectives are:
1- Understand the national and international legal and regulatory framework in which the research projects are designed and managed.
2- Understand and respond appropriately to the ethical and welfare issues that arise in the procedures in which experimental animals are used.
3- Learn how to design and manage an experimental procedure in order to achieve the established objectives, while guaranteeing compliance with current regulations.
4- Know how to develop the analysis of the data in order to present the results and the corresponding report.
Students who pass this subject may request the corresponding accreditation to develop the D function in the species of veterinary interest (domestic carnivorous, ruminants, equidae, birds, pigs , fish and lagomorphs) to the Directorate General for Environmental and Natural Environment Policies. Veterinary graduates who have also passed the subject "Laboratory Animal Science" may include rodents in the list of species for which they request accreditation for the development of function D

Content
THEORETICAL and PRACTICAL PROGRAM
Topic 1. Introduction to experimental design. Legal requirements and "3Rs". Steps to follow to perform the correct design of a procedure. Relation between experimental design and statistics. Consequences of an incorrect experimental design.
Topic 2. Systematic information search. Approach to hypotheses and objectives. Research of alternative methods to the use of laboratory animals (Go3Rs). ARRIVE guidelines for the dissemination of results
Topic 3. Type of variability: fixed variability and random variability. Sources of variability associated with the animal. Types of experimental models. Use and limitations of isogenic strains, not consanguineous and genetically modified.
Topic 4. Sources of variability associated with environmental factors. Importance of animal welfare in design and its effects on results. Application of refinement to guarantee animal welfare. Causes of the appearance of bias and ways to reduce them. Standardization
Topic 5. Identification of the experimental unit. Choice of treatments. Establishment of the experimental groups. Choice of variables to measure. Utility of pilot studies.
Topic 6. Types of experimental designs. Approach and use of complete random designs, random blocks, factorials, Latin squares and repeated measures in the same animal. Choice of design depending on the type of procedure and the factors involved.
Topic 7. Hypothesis test. Contrast of normality. Comparison of two averages: test power and sample size.
Topic 8. Analysis of designs ANOVA: complete random, factorial, random blocks, Latin square, repeated measures. Non-parametric methods.
Topic 9. Association of variables: correlation and regression. Analysis of covariance.
Topic 10. Responsibilities of the research staff regarding the use of animals for experimentation.
Topic 11. Preparation of projects for their evaluation in accordance with ethical principles and current legislation.
PROGRAM OF SEMINARS
Seminar: a teamwork session to design an experimental procedure

A 2-hour seminar will be held in which students will have to work as a team to design an experimental procedure, which will subsequently be discussed. Students will have to present three cases or exercises that will be scored and will be used to carry out the assessment. The resolution of each case is associated with 2.5 hours of tutoring that the student can use to resolve doubts, present the work in preparation, obtain advice, etc.
Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.

1-To pass the subject, at least 20 hours of class attendance is required.
1. In each case, at least 4 must be attained.
2. The final grade is obtained by adding the weighted notes of each one of the cases, and the approved one is placed in the 5.
Re-evaluation (recovery):
1. Each one of the cases in which the mark obtained has been less than 4 must be recovered.
