Data from 3,593 beef heifers and 4,079 of their steer paternal half-sibs were used to estimate genetic parameters of and among female growth and reproductive traits and male carcass traits. Estimates of heritability for adjusted 205-d weight, adjusted 365-d weight, age at puberty, calving rate, and calving difficulty measured on females were .16, .38, .47, .19, and .18, respectively; estimates ...

Chianina is the tallest and heaviest beef cattle breed in the world and 1 of the most appreciated breeds on the Italian meat market. A selection program focused on improving Chianina carcass quality could provide a further economic advantage to Chianina breeders. However, the current European carcass scoring system [i.e., the SEUROP (S=superior, E=excellent, U= very good, R=good, O=fair, and P=...

________________________________________________________________________________ Abstract The aim of this study was to estimate genetic parameters of some carcass characteristics in the Japanese quail. For this aim, carcass weight (Cw), breast weight (Bw), leg weight (Lw), abdominal fat weight (AFw), carcass yield (CP), breast percentage (BP), leg percentage (LP) and abdominal fat percentage (A...

in this study, production, reproduction, managerial, and economic parameters obtained from data recorded for lori-bakhtiari flock of sheep (500 heads of breeding ewe) stationed at the sheep's breeding station, were employed to determine the relative economic values of and breeding objectives for an annual cycle of production, in village system in this breed of sheep. economic value for a t...

The main purpose of this work was the characterization of Cabrito Transmontana goat kid carcass and meat, which is a Protected Origin Designation product. The effects of sex and carcass weight were studied. Sensory attributes of toughness, juiciness, flavor intensity, flavor quality, odor intensity, fiber presence (stringy), sweet intensity, and overall acceptability were evaluated in 60 males ...

Our study analyzed the carcass properties of 170 Korean native pigs in relation to carcass weight and back-fat thickness to provide general data for the production and distribution of high quality pig meat. The 70-74 kg group showed highest yield (73.41%). The ≥80 kg group showed the highest thickest back-fat (24.13 mm) (p<0.05). The ≥80 kg group showed the best quality grade (1.00). Back-fat t...

An experiment was conducted to study the eff ect of phytase enzyme (Natuphos 500) supplementation in Japanese quail (Coturnix japonica) (3 to 45 days of age) on body weight, carcass performance, percentage of tibia bone ash and tibia phosphorus. Data were analyzed as a completely randomized design arranged with fi ve levels (150, 300, 600, 1200 and 2400 FTU/Kg) of phytase enzyme as treatments 1...

Five single nucleotide polymorphisms (SNP) of the chicken insulin-like factor binding protein 2 (IGFBP2) gene were selected to genotype a F2 designed population with restriction fragment length polymorphisms and single stranded-conformation polymorphisms. The associations of the SNP and their haplotypes with chicken growth and carcass traits were analyzed. Results showed that the difference ind...

A joint growth-carcass model using random regression was used to estimate the (co)variance components of beef cattle body weights and carcass quality traits and correlations between them. During a four-year period (1994-1997) of the Australian "southern crossbreeding project", mature Hereford cows (N = 581) were mated to 97 sires of Jersey, Wagyu, Angus, Hereford, South Devon, Limousin, and Bel...

the diacylglycerol acyltransferase 1 gene (dgat1) was identified as a strong candidate gene affecting mutton quality traits in sheep. single nucleotide polymorphism creates a single base mutation (c to t) in agct site of endonuclease alui. dgat1 is one of the candidate genes to improve carcass characteristics in feedlot animals. in order to study area t487c in exon 17 of the dgat1 polymorphism,...
