Abstract: A divergência genética entre seis linhas de aves Legorne (L1, L2, L3, L4, L5 e L6), desenvolvidas pela UFV, foi avaliada utilizando análise de variáveis canônicas e o método de agrupamento de Tocher. Foram incluídas no estudo oito características: peso corporal na 40ª semana (PC40), na 48ª semana (PC48), na 56ª semana (PC56); peso do ovo na 40ª semana (PO40), na 44ª semana (PO44), na 52ª semana (PO52), na 60ª semana (PO60) e taxa de postura da 40ª a 62ª semana (TP). Foi observada diferença entre as linhas quan… Show more

“…Pires et al (2002) obtained canonical variables to study the genetic divergence among six Leghorn lines. Principal components analysis was applied by Liu et al (2004), who studied the physical, colour and sensory characteristics of chicken breasts deboned 2, 4, 6 and 24 h post mortem and by Pinto et al (2006), who studied the performance and carcass traits of two Brazilian chicken experimental populations designed to map quantitative trait loci.…”

“…-E-mail: millorfernandes@gmail.com Some interesting results have already been obtained on performance and genetic breeding of broiler chickens, demonstrating that is viable to use multivariate approaches, such as principal components analysis (Liu et al, 2004;Pinto et al, 2006) and cluster analysis using canonical variables (Viana et al, 2000;Carneiro et al, 2002;Pires et al, 2002).…”

“…Partial egg production records can be considered as longitudinal data and can be anaanalyzed during the life of an animal by using linear (Al-Samarai et al, 2008) or nonlinear funcduring the life of an animal by using linear (Al-Samarai et al, 2008) or nonlinear functions (Fialho and Ledur, 1997;Grossman et al, 2000) incorporated into repeatability (Wolc et al, 2007) or multitrait (Pires et al, 2002;Wolc et al, 2008) models. Random regression models (RRMs) are linear models, also known as finite-dimension models, are used to evaluate initial milk production in dairy cows (Jamrozik et al, 1997).…”

“…For cluster analysis, it was used Tocher method, adopting Mahalanobis distance as the dispersion measure, as mentioned by RAO (1952). Several authors have used these tests to study genetic divergence (VIANA et al, 2000;CARNEIRO et al, 2002;PIRES et al, 2002;VENTURA et al, 2012).…”

“…Amongst them, canonical variables technique represents an important tool in discriminating genetic groups, allowing the verification of the degree of similarity through unior multi-dimensional dispersion diagrams involving canonical averages. Cluster analysis is used by several authors (PIRES et al, 2002;YAMAKI et al, 2008;VENTURA et al, 2012) as another type of multivariate technique which allowing sampling units to be synthetized in a number of groups. So, homogeneity in cluster and heterogeneity between the clusters are maintained (CRUZ et al, 2004),Therefore, this study aimed to verify the genetic divergence amongst three broiler genotypes, from both sexes, by using performance and carcass traits with the multivariate analysis technique.…”
