Resumo: The objective of this study was to evaluate the effect of parity on linear trait types in Guzerá cows using multivariate techniques. Data were collected from 68 purebred Guzera females, young (1st and 2nd calving order) and adults (3rd to 7th calving order). Measurements were collected using a tape measure, a hypometer, a 40 cm graduated ruler and a 180° protractor. PRCOMP procedure of the R program was used for analyzing the main components. The variables related to rump (height, angularity, ileum and ischium length and width), body (length), udder (height of posterior ligament) and milk production were more important to explain the phenotypic variation in Guzerá cattle. Young Guzerá cows had lower body length, narrower rumps, better udder ligaments and lower milk yield than adult cows.

Foram utilizados dados de 68 fêmeas da raça Guzerá, puras de origem, jovens (1ª e 2ª ordem de parto) e adultas (3ª a 7ª ordem de parto). As medidas foram coletadas com auxílio de fita métrica, hipômetro, régua graduada de 40 cm e transferidor de ângulos 180°. Para as análises de componentes principais utilizou-se o procedimento PRCOMP do programa R. As variáveis relacionadas à garupa (altura, angulosidade, comprimento e largura de íleo e ísquios), corpo (comprimento), úbere (altura do ligamento posterior) e produção de leite apresentaram maior importância para explicar a variação fenotípica de bovinos Guzerá. Vacas jovens da raça Guzerá apresentaram menor comprimento corporal, garupas mais estreitas, melhores ligamentos de úbere e menor produção de leite que as vacas adultas.UEL2017-08-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/2772410.5433/1679-0359.2017v38n4Supl1p2755Semina: Ciências Agrárias; Vol. 38 No. 4Supl1 (2017); 2755-2764Semina: Ciências Agrárias; v. 38 n. 4Supl1 (2017); 2755-27641679-03591676-546Xreponame:Semina.
