1 Estimation of genetic parameters between single-record and multiple-record traits using ASREML Sansak Nakavisut Principle supervisor: Dr Ron Crump Co-supervisor: Dr Hans Graser

2 Outline Introduction Univariate analysis of single-record traits ( eg ADG ) Bivariate analysis of 2 (single-record) traits (eg ADG & FI) Univariate analysis of multi-record traits (eg NBA) Bivariate analysis of single & multi-record traits Problems / solutions Demonstration

3 Introduction Aim: to demonstrate how to estimate genetic parameters from a more complex model using ASREML Data set up to match the model Concept of multi-record traits (repeated measurements of the same traits) Problems you may encounter in bivariate analysis and solutions

4 Univariate analysis of single-record trait One record per animal during the life time eg BW, TN, BF, FCR, ADG, FI, etc., Genetic parameters; h a 2, h m 2, c 2, r am, estimable and reliable or not, depending on data structure Std. error will reflect data structure (Qnt Qly)

10 Univariate analysis of multi-record trait When r g between 2 measurements is 1 or close to unity, “repeated measurements of the same trait”, within-individual variance is caused by temporary differences of environment Otherwise, we should treat them as “2 different traits” they are not under the same genetic control Genetic parameter estimates; h a 2, h m 2, c 2, r am if data structure allows PLUS repeatability (r)
