ABSTRACT. Due to the relevance of carcass and meat quality traits as breeding objectives of Texel as sire terminal breed, a progeny testing was implemented. In general, these difficult to measure traits have received less attention despite their economic relevance, particularly in more extensive environments in which sheep production is mainly located.

ABSTRACT. Preweaning growth and viability traits of 1047 lambs from a diallel cross between Texel and Corrie-dale were recorded between 2010 and 2013. Birth weight of live born lambs (BWT), weaning weight at 80 days of age (WWT), growth from birth to weaning (GBW), lambs via-bility at birth, at 72 hrs of age and at weaning were evaluat-ed. Crossbreeding parameters were estimated. There were significant (P

ABSTRACT. The present study reports preliminary estimates of heritabilities of meat quality traits and genetic correlation among them and with carcass quality based on data on 424 lambs of the Texel Central Progeny Testing in Uruguay. Moderate heritabilities were estimated for color parameters, Warner-Braztler shear force (WBSF), intramuscular fat content (IMF) and fatty acid profile (percentage of saturates, monounsaturated and polyunsaturated fatty acids). Genetic correlations between fat thickness by ultrasound and GR were positive and moderate between them and with IMF.
