Important topics in breeding planning are to compare genetic progress with the increase in inbreeding, and to explain and compare risks and consequences of different breeding schemes using simulation tools. Topics to be covered in the course include formulation of breeding goals, modeling and simulation, use of molecular information, reproductive technologies, selection strategies and mating strategies. The course will focus on developing a deterministic model to predict response to selection, understanding the components of the model and to use the model in comparing alternative breeding plans for pigs, cattle, goats, poultry and fish.
Computer exercises will mainly be based on R.
Students should be able to
- Explain the elements required to set up a successful breeding scheme.
- Compare principles underlying the definition of breeding objectives and methods for their derivation.
- Describe and use stochastic and deterministic methods for predicting effects of breeding schemes
- Model specific breeding schemes and predict their effects.
- Explain the effects of reproductive and genomic technologies.
- Explain methods for maintaining genetic diversity in the presence of selection.
- Discuss optimization of breeding plans in the presence of genotype-environment interactions and breeding plans utilizing cross breeding.
- Describe principles for dissemination of genetic progress.
In earlier courses, breeding plans and theory are presented. In this course students will develop a more detailed understanding of the elements of breeding schemes. Particularly, focus will be on understanding elements of and implementation of a deterministic model to predict response to selection in realistic breeding schemes. Through individual studies, group exercises, individual semester assignments, the use of models developed in the course and lectures, students should be able to evaluate:
- Implications of biological factors and technological elements for breeding.
- The definition of breeding goals, and what traits to register.
¿ Derivation of economic values in breeding goals, and calculation of economic gain from breeding.
¿ Comparison of alternative breeding schemes.
Students will analyse breeding schemes for fish, pigs, poultry, cattle, sheep and/or goats through written reports and presentations.
