Abstract

GOMES, Helen Fernanda Barros et al. Carcass traits of characteristics of kid goats from five breed groups raised in a feedlot system. R. Bras. Zootec. [online]. 2011, vol.40, n.2, pp.411-417. ISSN 1516-3598.  https://doi.org/10.1590/S1516-35982011000200024.

This study was carried out with the objective of evaluating the influence of breed groups and sexual conditional on carcass traits of young goats raised in feedlot. It was used 91 animals, 52 males and 39 females, belonging to five breed groups: Alpine, ½Boer + ½Alpine, ½Nubian + ½Alpine, ¾Boer + ¼Alpine and ½ Anglo-Nubian + ¼Boer + ¼Alpine. On the slaughter day, the shrunk weight was measured after 24 hours of solid fasting. Biometric and carcass measures were objectively and subjectively taken. Racial group influenced withers, internal and external carcass length, and leg length, which were greater for Alpine animals, as well as chest width, body condition score, carcass and leg compactness index and fat thickness on carcass, which were better in animals with Boer blood degree. Male animals showed greater withers, measures of sternebrae by ultrasound, internal carcass length, leg length, tissue depth height between 3rd and 4th sternebrae measured on carcass. On the other body evaluated characteristics, it was not found any differences among breed groups and sex of the animals. Crossing Boer with Alpine reduces carcass length, and increases fat thickness and deposited tissue, however, it does not change animal performance.
