| Data from 2439 goats of the Saanen, Alpine, Anglo Nubian and Toggenburg breeds recorded from 1976 to 2009 by the Association of Goats and Sheep Breeders of Minas Gerais were used in principal component analysis. After consistency of data, six morphological variables (thorax perimeter, body length, withers height, height, width and length of the rump) and 12 variables related to breed standard score and fitness (breed characteristic, head, palette and topline, feet and legs, dairy type, body capacity, udder, rear and front ligament, udder texture, teat and final score) were analyzed. Based on the magnitude of the eigenvalue (lower than 0.7), eleven variables considered redundant were discarded, resulting in reduced costs of technician labor to evaluate the... |

| ABSTRACT: The aim of this study was to verify the genetic divergence amongst three broiler genotype, from both sexes, by means of a multivariate performance analysis and carcass traits. Nine hundred and ninety sexed, one-day chicks were utilized; belonged to the following genetic groups: Cobb 500, Hubbard Flex, and Ross 308. The study evaluated the daily average weight gain, the daily average ration consumption, feed conversion, body weight, weight and performance for breast, and carcass over the period from 1 to 35, and from 1 to 42 days of age. Performance of the genetic groups was evaluated by means of multivariate analysis of variance and by Fisher's linear discriminant function, using Roy's largest eigenvalue and Roy's union-intersection test for... |

| Objetivou-se verificar a divergência genética entre linhagens de codornas de corte e seus cruzamentos para as características de desempenho através da análise multivariada. Foram utilizadas quatro linhagens de codornas de corte em um sistema de cruzamentos dialélicos completos, proporcionando a formação de 16 grupos de progênies, sendo quatro parentais puros: L1, L2, L3 e L4; seis grupos genéticos mestiços F1: G12, G13, G14, G23, G24 e G34; e seis grupos genéticos mestiços F1 recíprocos. Foram avaliadas as seguintes variáveis: peso corporal médio ao nascimento, aos 28, aos 35 e aos 42 dias de idade; o consumo médio de dieta do nascimento aos 35 e aos 42 dias de idade; a conversão alimentar do nascimento aos 35 e aos 42 dias de idade; e o ganho em peso do... |
