Given the growing use of alternative sources protein, studies on commercial viability amazonians wild species, based yield their carcass, are still scarce in literature. To evaluate yields carcass and cuts caiman meat (Caiman crocodilus yacare), according to sex weight categories, besides analyzing revenue. Thirty animals termination phase were selected, separated by weighed. The analyzed was 5...

Article history: Received 21 April 2008 Received in revised form 31 October 2008 Accepted 5 November 2008 Sixty crossbred (Iberian dam×Duroc sire) females, 80 days of age (17.6±0.13 kg body weight, BW), was used to investigate the effect of castration on productive performance, carcass and meat quality and fatty acid profile of backfat (BF). There were 2 treatments (intact females, IF; castrate...

The present experiment, ‘Regional Combinations’, examined growth, and carcassandmeat-quality traits in the progeny of sires genetically diverse for fatness and meat yield when grown at different rates from weaning to feedlot entry. The present paper is the first of several papers describing results from the New South Wales site, one of four in the project. It reports the effects on growth and b...

Carcass (n = 568) and longissimus thoracis palatability (n = 460) traits from F1 steers obtained from mating Hereford (H), Angus (A), and U.S. Meat Animal Research Center (MARC) III cows to H, A, Norwegian Red (NR), Swedish Red and White (RW), Friesian (F), or Wagyu (W) sires were compared. Data were adjusted to constant age (471 d), carcass weight (356 kg), fat thickness (1.0 cm), percentage o...

To evaluate effects of previous forage systems on feedlot performance, yearling Hereford steers (average initial weight of 249 kg) were grazed on tall fescue (TF), smooth bromegrass-red clover (BG-RC) or orchardgrass-red clover (OG-RC) pastures before finishing. Serial slaughter was utilized during the first 2 yr of this study to determine changes in carcass characteristics throughout finishing...

The objective of this study was to evaluate performance, gastrointestinal morphometry, carcass, and non-carcass traits in lambs finished on different levels canola grain the diet. Twenty-seven Santa Ines with an average initial weight 19.33 ± 1.39 kg were given diet: 0, 8, 16%. Weights body condition scores determined at beginning, every 14 days end experimental period. Animals slaughtered asse...

A field study was conducted to evaluate the influence of some pre-slaughter factors as journey time, stocking density, and lairage time on mortality, live weight loss and carcass defects on 321 flocks of broiler chickens slaughtered at a commercial processing plant. For each flock, the following traits were evaluated: birds dead-on-arrival (DOA); live weight loss; condemned carcasses; downgrade...

OBJECTIVE The aim was to evaluate carcass characteristics, cut yield, and meat quality in lambs that were fed different inclusion levels of palm kernel cake. METHODS Forty-five woolless castrated male Santa Inês crossbred sheep with an initial average body weight of 23.16±0.35 kg were used. The experimental design was a completely randomized design with five treatments, with palm kernel cake ...

BACKGROUND Dietary fats can alter the deposition and distribution of body fats in ruminants. The deposition and distribution of body fat play a vital role in the quality of ruminant carcasses and are of great commercial value since they influence the profitability and consumer acceptability of ruminant meat. The current study examined the effects of dietary blend of 80 % canola oil and 20 % pal...

Cattle (n = 995 steers and 757 heifers) were randomly selected from a commercial abattoir (Emporia, KS) to determine the relationships between USDA quality and yield grade characteristics and serum concentrations of leptin, IGF-I, and GH. Animals were randomly selected postexsanguination on the slaughter line on 4 occasions (March, May, August, and January). Blood was collected at exsanguinatio...
