| Educational objectives | Provide a depth knowledge of livestock aimed at the application of biodiversity conservation methods in order to be able to define conservation plans of endangered breeds, also by means of molecular genetic techniques. Defining genetic selection plans. |
| Prerequisites | Biostatistics applied to innovative and sustainable livestock productions. |
| Teaching methods | The course is organized as follows: -front -lessons classroom on the topics listed in the program; -guided exercises with the computer aid on the topics explained during the course; -final exercise with the final written test simulation; -seminars on the topics covered. |
| Other information | Lecture participation’s is recommended |
| Learning verification modality | The examination consists in a final written exam lasting about three hours in which students must demonstrate that they are able to calculate: the effective size of a population; the classification of a population according to FAO and EAAP classifications, breeding value, relationship and genetic indexes of sire. The oral test will allow verifying the student's communication skills with language properties and the ability to apply the acquired skills. |
| Extended program | Biodiversity animal genetic drift, small animal populations, conservation techniques (in situ and ex situ), calculation of the actual number, examples of conservation. Introduction to animal breeding Recall quantitative traits, qualitative and threshold, the infinitesimal genetic model, estimate the correct phenotype, breeding value and the value of the gene combination. Estimate of genetic indexes Calculation of genetic indexes single trait, pedigree index, multiple trait index, accuracy of the estimate and confidence interval, Producing Ability, BLUP estimates: sire and animal models; genomic and selection; calculation of progress genetic. Genetic evaluation of sire (performance testing, progeny testing, sib test). PRACTICAL LESSONS Calculation of the effective population size and F statistics (Wright). Calculation of single genetic trait, multiple-trait, pedigree, Producing Ability, estimation accuracy and genetic progress, resolution of models for estimating indices BLUP sire and animal in a manual and with the aid of computer tools (Excel and software R). |
