The present work describes the effect of nutritive level on horse carcass traits and on meat quality. Eighteen male Italian Heavy Draught Horse (IHDH) breed foals were employed in the study. Soon after foaling they were randomly subdivided into three groups according to three nutritive level classes: 150%, 180% and 200% of maintenance requirements. Live weight, hot carcass weight and dressing p...

Postweaning growth, feed efficiency, and carcass traits were analyzed on 1,422 animals obtained by mating F1 cows to F1 (Belgian Blue x British breeds) or Charolais sires. Cows were obtained from mating Hereford, Angus, and MARC IIIHereford, 1/4 Angus, 1/4 Pinzgauer, and 1/4 Red Poll) dams to Hereford or Angus (British breeds), Tuli, Boran, Brahman, or Belgian Blue sires. Breed groups were fed ...

Multiple linear regression equations predicting total skeletal muscle (TM) and total skeletal fat-free muscle (TFFM) weight were developed from data of 33 beef cows. Animals varied in weight (385 to 749 kg), age (3 to 10 yr), and fatness (.13 to 2.54 cm). A four-terminal impedance meter/plethysmograph measured resistance and reactance on the live animals, exsanguinated (bled) animals, and on th...

The purpose of this study was to characterize and compare the carcass characteristics, cholesterol concentration, fatty acid composition of intramuscular fat and subcutaneous fat, and meat quality of Criollo Argentino and Braford steers reared in an extensive system, without supplementation, and slaughtered at approximately 400kg live weight. The Braford steers had greater (P<0.05) carcass weig...

The present study was carried out to study the carcass and meat quality traits of two breeds of [New Zealand White (NZW) and Californian (CAL)] under environmental conditions in Egypt. Two hundred of NZW and CAL (100 rabbits of each bread of 50 males and 50 females) aged and slaughtered at 12 weeks .The following traits were recorded: body weight at slaughter age carcass weight, meat, fat and a...

Steers from research crossbreeding projects (n = 406) were serially scanned using real-time ultrasound at 35-d intervals from reimplant time until slaughter. Cattle were evaluated for rump fat depth, longissimus muscle area (ULMA), 12th-rib fat thickness (UFAT), and percentage of intramuscular fat (IMF) to determine the ability of ultrasound to predict carcass composition at extended periods be...

Th is study investigated the relationships between ultrasound measurements of backfat thickness (UBF) taken on live heavy pigs and several carcass composition and ham quality traits. Before slaughter 240 pigs were weighed (average BW: 167 ± 10 kg) and assessed for UBF using an A-mode ultrasonic device (placed above the last rib at approximately 5.5 to 8.0 cm from midline, with increasing distan...

Carcass and price traits of 72,969 Hanwoo cows, bulls and steers aged 16 to 80 months at slaughter collected from 2002 to 2013 at 75 beef packing plants in Korea were analyzed to determine heritability, correlation and breeding value using the Multi-Trait restricted maximum likelihood (REML) animal model procedure. The traits included carcass measurements, scores and grades at 24 h postmortem a...
