Course contents summary
Quantitative traits (variability, composition of phenotypic variability, environmental variability, additive and non-additive effects of genes, inheritability, repeatability). Importance of genetic variability and of biodiversity. Management of limited populations. Genetic improvement of animals in zootechnical production. Organisation of selection in Italy (genealogical books, registers). Animal production recording systems. Relatedness and its calculation. Methods for estimating the genetic merit of breeding animals (performance test, Sib test, progeny test, BLUP-animal model). Direct and indirect selection, genetic progress, multiple trait selection. Reproduction methods: inbreeding and crossbreeding. Application of genetic improvement to the main zootechnical productions (bovine: milk and meat; swine: meat).
ZOOTECHNICAL ETHNOGRAPHY AND ETHNOLOGY
General characters, origin, evolution, diffusion, classification of the main breeds:
ovine breeds bred in Italy depending on their potentiality; foreign ovine breeds of major interest for Italian breeding farms;
classification of canine breeds.
