The objective was to evaluate different levels of crambe cake (CC) protein (0, 250, 500, 750 and 1000 g/kg DM) as a replacement for soybean meal in diets lambs their effect on performance, carcass traits meat quality. Forty not castrated crossbred male lambs, weighing 20 ± 3.45 kg, were settled completely randomized design with eight replicates per treatment. Final body weight (BW), dry matter ...

An F2 Japanese quail population was developed by crossing two strains (wild and white) to map quantitative trait loci (QTL) for performance and carcass traits. A total of 472 F2 birds were reared and slaughtered at 42 days of age. Performance and carcass traits were measured on all of the F2 individuals. Parental (P0), F1 and F2 individuals were genotyped with 3 microsatellites from quail chrom...

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...

The objective of this study was to quantify the genetic variation in carcass cuts predicted using digital image analysis in commercial cross-bred cattle. The data set comprised 38,404 steers and 14,318 heifers from commercial Irish herds. The traits investigated included the weights of lower value cuts (LVC), medium value cuts (MVC), high value cuts (HVC), very high value cuts (VHVC) and total ...

Forty Najdi ram lambs weighing 26.6±0.3 kg were utilized in this experiment to determine the effects of feed restriction followed by realimentation and body weight at the onset of feed restriction (30 and 36 kg body weights) on performance and carcass characteristics; feeding and restriction levels were ad libitum, 0.75 and 0.60 of the ad libitum intake. All lambs were slaughtered after 14 week...

Current research was conducted to estimate heritability and genetic correlations for carcass composition and fat deposition in Japanese quail at 42 and 91 d of age. Studied traits were BW at 42 and 91 d of age (BW42, BW91), carcass weight and percentage, breast meat weight and percentage, thigh weight and percentage, abdominal fat weight and abdominal fat percentage (AFP), skin weight and skin ...

Th e aim of the study was to compare carcass traits between Cika and Brown cattle of all slaughter categories. Th e data used were collected in Slovenian slaughterhouses from 2007 to 2010. Aft er the slaughter carcass weight was recorded and carcass conformation and fatness were scored according to the EUROP system. Net daily gain was calculated. Data were analysed by GLM procedure of statistic...

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...

body weight (bw) and carcass traits are complex and important economic traits that may benefit from the implementation of mas. the objective of the current study was to identify qtl associated with bw and carcass traits in an experimental half-sib cross of japanese quails selected for bw at 4 weeks of age. body weight and carcass traits were measured in the f2 population. total f2 individuals a...

A joint growth-carcass analysis was conducted to develop equations for predicting carcass quality traits associated with variation in growth path of crossbred cattle. During a four-year period (1994-1997) of the Australian "Southern Crossbreeding Project", mature Hereford cows (r = 581) were mated to 97 sires of Jersey, Wagyu, Angus, Hereford, South Devon, Limousin, and Belgian Blue breeds, res...
