Data from 156 Nellore males were used to develop equations for the prediction of retail beef yield and carcass fat content, expressed as kilograms and as a percentage, from live animal and carcass measurements. Longissimus muscle area and backfat and rump fat thickness were measured by ultrasound up to 5 d before slaughter and fasted live weight was determined 1 d before slaughter. The same tra...

In order to estimate genetic parameters for body weights and carcass yield of 2 strains of quails; 32 pairs of Japanese quail (coturnix Japanese) and 26 pairs of range quail (coturnix ypisilophorus) randomly were selected from the base populations of parents. Produced progenies (650 birds) were used to estimate the genetic parameters of body weights and carcass characteristics traits. Body weig...

A study on insect succession of monkey carcass in a forested area in Ulu Gombak, Selangor, Malaysia was conducted from 9 May to 18 June 2007. The third instar of the housefly, Musca domestica (Linnaeus) (Diptera: Muscidae) were only found on dry stage of a decomposed (Day-33) monkey carcass (Macaca fascicularis Raffles). This observation revealed that M. domestica maggots were found together wi...

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...

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 ...

The carcass size performances and the meat quality of Gannan and Sibu yak were determined using M. supraspinatus (SU), M. longissimus thoracis (LT) and M.quadriceps femoris (QF). It is found that Sibu yak had significantly higher carcass weight (CW) than Gannan yak with difference of nearly 40 kg, as well as significantly higher eye muscle area (EMA), carcass thorax depth (CTD), round perimeter...
