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 […]

Principal component analyses were applied to carcass records of 367 animals of a F2 swine population. Starting from 33 traits, 17 showed variation lower than 0.7 (eigenvalue lower than 0.7) and significant simple linear correlations with the other traits, indicating they were redundant. These results suggest the following variables to be used in future carcass studies: slaughter age; right side carcass weight; carcass length by the Brazilian Method of Carcass Classification; higher backfat thickness at boston shoulder area and in […]
