Carcass quality of JamunaparixBlack Bengal (JBB), Black Bengal selected for growth (SBB) and random-bred (RBB) wethers of 1 year of age was studied. There was no significant difference between JBB and SBB in pre-slaughter traits and carcass characteristics, except height at wither and dressing percentage which were significantly higher in JBB than in SBB, and muscle fiber diameter which was sig...

Carcass growth is made up primarily of fat and protein. As cattle approach mature weight, carcass gain makes up a higher percentage of total gain. This is why dressing percentage increases with days on feed. Although performance is typically reduced for long fed cattle, adjusting performance for dressing percent can give us an indication of the performance of carcass growth. Fat makes up a high...

Carcass EPDs are becoming common in this era when more economically important traits are being added to national cattle evaluation programs. Traditionally, carcass traits were evaluated solely using progeny tests. One limitation to progeny testing is, of course, cost. Also, for bulls to be evaluated in such a program, he must produce progeny on which carcass data are collected. This is a proces...

Eight different morphometric dimensions were monitored on 106 lamb carcasses belonging to three Catalan meat sheep breeds (Ripollesa, Rousillon Red and Xisqueta). Our purpose was to examine differences with regard to measurable carcass dimensions and also to establish between and within breed relationships among the carcass components. Measured variables included: carcass weight (CW), leg lengt...

The objective of this experiment was to determine if growth, carcass composition, and myofiber characteristics of lambs were affected by heterozygosity for a myostatin mutation (g+6723G>A) when offered differing allowances of feed administered with or without ractopamine. Heterozygote [MSTN A/G (n = 40)] and homozygote wildtype [MSTN G/G (n = 39)] castrate male lambs were individually fed ad li...

In three separate studies (156 pigs total), dual-energy X-ray absorptiometry (DXA), bioelectrical impedance (BIA) and ultrasound were compared as methods for measuring live body composition of pigs at 60 and 100-110 kg BWt. DXA measured total body fat and lean content, BIA measurements of resistance (Rs) and reactance (Xc) were used to calculate total body lean mass and ultrasound measurements ...

The aim of this study was to develop and evaluate models for predicting the carcass composition of lambs. Forty male lambs of two different breeds were included in our analysis. The lambs were slaughtered and their hot carcass weight was obtained. After cooling for 24 hours, the subcutaneous fat thickness was measured between the 12th and 13th rib and the total breast bone tissue thickness was ...

An investigation was carried out to assess the carcass characteristics and meat quality aspects of immunocastrated male pigs of medium genetic potential for lean meat deposition in carcass (53 to 55%). When the crossbred Large White x Landrace pigs (n = 45) were 70 days old, they were distributed in a totally randomized design in three treatments (castrated males, females and immunocastrated ma...

The aim of the study was to establish the relationship between a calpastatin gene (CAST) polymorphism, the ryanodine receptor gene (RYR1) polymorphism and carcass/meat quality traits in crossbred pigs. No significant differences in the analyzed pigs were found between genotypes CC and CT at the locus RYR1 and CD and DD at the locus CAST/MspI in terms of carcass and meat quality. However, a sign...

Received: 29/04/2013 Revised: 17/09/2013 Accepted: 23/09/2013 Abstract Accurate prediction of carcass evaluation in live animals may allow more efficient genetic improvement of meat quality. Effective value-based marketing programs require precise techniques for assessing composition, palatability and other factors associated with consumer acceptance of meat products. The ultimate test for a ca...
