The objective of this study was to benchmark carcasses and muscles from commercially identified fed (animals that were perceived to have been fed an increased plane of nutrition before slaughter) and nonfed cull beef and dairy cows and A-maturity, USDA Select steers, so that the muscles could be identified from cull cow carcasses that may be used to fill a void of intermediately priced beef ste...

These studies evaluated the effects of betaine, provided either as feed-grade betaine or as concentrated separator by-product (CSB; desugared beet molasses), on performance and carcass characteristics of finishing cattle. In Exp. 1, 175 steers (410 kg initial BW) were fed a finishing diet based on steam-flaked and dry-rolled corn, and treatments included 10.5 and 21 g/d feed-grade betaine and 2...

Genetic and sex differences or variation in carcass characteristic and slaughter yield were studied using a total of 150 intensively reared and clinically normal chickens consisted of 50 each of normal feather, naked neck and frizzled matured chickens genotypes. The result showed that genotype as well as sex have significant effect (P<0.05) on carcass characteristics and slaughter yield at twen...

Objectives of this study were to determine the influence of trenbolone acetate (TBA) and estradiol (E2) in a combined implant on feedlot performance, carcass characteristics, and carcass composition in finishing steers. Sixty-four large-framed (394.1 kg) crossbred steers were randomly assigned to one of four pens. Subsequently, pens were randomly assigned to one of two treatments, implanted (12...

Abstract The aims of this study were to determine the prevalence carcass lesions in slaughtered pigs and quantify their relationships with different animal characteristics, pre-slaughter factors, blood measurements, performance indices, composition meat quality traits. Data was recorded for 30 journeys referring 1080 market-weight that originated from 15 commercial small-scale finishing farms. ...

This experiment had been done to evaluate the effects of different levels of essential oils (EOs) of wormwood (Artemisia absinthium) and cumin (Cuminum cyminum)on growth performance, carcass characteristics and immune system in broiler chicks. Three hundred ninety two Ross 308 male broiler chicks in a completely randomized design were divided into 7 experimental treatments. The experimental tre...
