Genetic parameters were estimated between current UK hill sheep breeding goals and lamb carcass composition and muscularity traits derived using X-ray computed tomography (CT). To produce these estimates, a total of 648 lambs from two hill farms were CT scanned at weaning (ca 120 days of age), over 3 years, and total weights of carcass muscle (MUSC), fat (CFAT) and bone (BONE) and internal fat ...

ABSTRACT: The study evaluated the effect of sex and slaughter weight on carcass traits non-carcass components 1,489 horses (739 geldings 750 females, classified into eight groups according to their weight). Data were analyzed under a completely randomized design. Geldings had higher (P < 0.05) hot yield (HCY) cold (CCY) than females; however, fat yellowness values (b*) greater in females. Sl...

The aim for this study was to derive economic values for meat quality traits. Meat quality experts from 10 slaughter and retail companies in Switzerland were asked to give an interview in which they indicated their willingness to pay different prices for carcasses from different quality classes. Economic values for the seven meat quality traits color (L*), drip loss, intramuscular fat content, ...

Carcass composition of Iberian pigs is very important because it influences the quality of their cured products. Therefore, the objective of this study was to determine the effects of sex and slaughter weight on carcass traits measured in vivo with ultrasound and subsequently in the carcass. One hundred and sixty five castrate males and females with a weight ranging from 130 to 175 kg were ultr...

The pH values and temperatures at 45 min, and 3, 9, 15, and 24 h postmortem in the LM and semimembranosus muscle (SM) and glycolytic potential in LM were measured in 1,030 F(2) animals from a White Duroc x Erhualian resource population. A whole genome scan was performed with 183 microsatellites covering 19 porcine chromosomes to detect QTL for traits measured. A total of 73 QTL have been identi...

The study evaluated the body weight during growth (BWG), body weight at slaughter (BWS), breast meat yield (BMYg), percent breast meat yield (BMY) and breast meat quality (colour and drip loss) of genetically featherless (scsc) broilers compared to their feathered sibs under hot conditions. Two hundred featherless chicks and 200 feathered sibs were reared under hot conditions in two rooms (aver...

The objective of this study was to characterize breeds representing diverse biological types for postweaning growth and carcass composition traits in terminal crossbred cattle. Postweaning growth and carcass traits were analyzed on 434 steers and 373 heifers obtained by mating F1 cows to Charolais sires. Maternal grandsires represented Hereford, Angus, and MARC III (1⁄4 Hereford, 1⁄4 Angus, 1⁄4...
