Spanish x Boer (n = 16) and Spanish x Kiko (n = 18) wethers (7 mo) and bucklings (5 mo) were harvested under USDA inspection to evaluate the effect of dam breed on carcass traits of crossbred kids. Boer and Kiko dams, respectively, originated from five and seven seedstock farms. Each dam was purebred or fullblood (93.75 to 100%). Traits of interest included live weight and conformation score, c...

An experiment was conducted to determine the effects of unsaturated fatty acids supplementation on growth performance and carcass characteristics of finishing lambs. Thirty-two finishing Afshari lambs (initial weigh 58 ± 5 kg and 8 mo age) were used in a completely randomized design with 4 treatments (slaughtered in time series) and 8 lambs/treatment for the final 30 d before slaughter. The sla...

Genetic correlations between performance traits with meat quality and carcass traits were estimated on 6,408 commercial crossbred pigs with performance traits recorded in production systems with 2,100 of them having meat quality and carcass measurements. Significant fixed effects (company, sex and batch), covariates (birth weight, cold carcass weight, and age), random effects (additive, litter ...

ABSTRACT: The study evaluated the effect of sex and slaughter weight on carcass traits non-carcass components 1,489 horses (739 geldings 750 females, classified into eight groups according to their weight). Data were analyzed under a completely randomized design. Geldings had higher (P < 0.05) hot yield (HCY) cold (CCY) than females; however, fat yellowness values (b*) greater in females. Sl...

Pork quality and carcass characteristics are now being integrated into swine breeding objectives because of their economic value. Understanding the genetic basis for these traits is necessary for this to be accomplished. The objective of this study was to estimate phenotypic and genetic parameters for carcass and meat quality traits in 2 Canadian swine populations. Data from a genomic selection...

The aim of this study was to evaluate the productive and biological efficiency of steers and heifers from dairy genetics in a feedlot system in terms of meat production. Twenty-four steers and 24 heifers at 10 monthes of age, (3/4) Zebu × (1/4) Holstein were utilized. They were distributed over four feedlot times, 30, 60, 90, and 120 days with four replications for each sex, and were slaughtere...

twenty four male lambs divided into four groups and were allocated to 90, 105, 120 and 135 days of fattening periods.at the end of each fattening period, lambs were slaughtered. the percentage of cold carcass on the basis of empty body weight in the mentioned periods were 57.0 ± 0.94, 57.5 ±1.7, 59.9 ±3.3 and 62.2 ±4.4,respectively(p
