The current study was designed to estimate the pork quality traits using metabolites from exsanguination blood and postmortem muscle simultaneously under the Korean standard pre- and post-slaughter conditions. A total of 111 Yorkshire (pure breed and castrated male) pigs were evaluated under the Korean standard conditions. Measurements were taken of the levels of blood glucose and lactate at ex...

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 464 steers and 439 heifers obtained by mating F(1) cows to Charolais and MARC III (1/4 Hereford, 1/4 Angus, 1/4 Pinzgauer, and 1/4 Red Poll) sires. The F(1) cows wer...

Lamb growth, survival and carcass characteristics were compared for progeny of either 1/2-Suffolk, 1/2-Rambouillet (Western) ewes or 1/2-Suffolk, 1/4-Rambouillet, 1/4-Finnsheep (1/4-Finn) ewes produced over 3 yr in three different management systems. System 1 lambs were born in late fall and fed to slaughter on a concentrate diet. System 2 lambs were born in January and February and grazed pure...

Pigs representing two crossbred genotypes, a breeding company hybrid (BCH) and a three breed cross (Hampshire x [Yorkshire x Duroc]) (HYD) were evaluated at five slaughter weights (SLW): 100, 115, 130, 145, and 160 kg. A total of 160 pigs were grown in like-sex (barrows [B] or gilts [G]), like-genotype groups, with four pigs/group, from 60 kg live weight. A corn-soybean meal-based diet was avai...

Little scientific information is available that has evaluated safflower (Carthamus tinctorius) cake as a substitute to conventional ingredients in small ruminants diet. The objective of this work was to evaluate the effect of feeding safflower cake in total mixed rations (TMRs) on lamb and kid growth rates, carcass traits and meat fatty acid composition. Two consecutive trials were conducted us...

Fifty-five fall-born, Simmental-crossbred, male calves were allotted at birth to one of five treatments: bulls castrated at 5 mo and implanted from birth to slaughter (ST); bulls implanted from birth to slaughter (BI-BS); bulls implanted from birth to weaning (BI-BW); bulls implanted from weaning to slaughter (BI-WS) and non-implanted control bulls (CB). Implanted calves received 36 mg of zeran...

The objective of this study was to evaluate the effects of three alternative (ALT) rearing systems for growing pigs (outdoor: 150 m2/pig; straw bedding: 1.30 m2/pig; and hut with access to a courtyard: 1.30 m2/pig) compared with a conventional system (fully slatted floor: 0.65 m2/pig, considered as control), on pre-slaughter stress indicators in relation with meat quality. To that end, the numb...
