Abstract The aims of this study were to determine the prevalence carcass lesions in slaughtered pigs and quantify their relationships with different animal characteristics, pre-slaughter factors, blood measurements, performance indices, composition meat quality traits. Data was recorded for 30 journeys referring 1080 market-weight that originated from 15 commercial small-scale finishing farms. ...

Genetic parameters of Berkshire pigs for reproduction, carcass and meat quality traits were estimated using the records from a breeding farm in Korea. For reproduction traits, 2,457 records of the total number of piglets born (TNB) and the number of piglets born alive (NBA) from 781 sows and 53 sires were used. For two carcass traits which are carcass weight (CW) and backfat thickness (BF) and ...

Consumers believe that quality of foods from organic production is superior to foods from conventional production. The objectives of the present study have therefore been to compare the quality of chicken meat from organic and conventional production on the basis of traditional meat quality criteria. The experiment was organized as a field study. Fresh organic broiler carcasses were purchased d...

The effect of carcass weight, age at slaughter and sex on some chemical components was evaluated in twenty-two Boutsiko lambs (twelve females and ten males). Chemical composition of meat was expressed as percentage of fat, protein, collagen and moisture content. Measures of the four chemical components were taken by carcass cuts included shoulder, leg, racks, kidney, rear flank, breast ribs and...

Because of the Ca dependency of the calpains, oral supplementation of vitamin D3 (VITD) can increase the Ca content of muscle to activate the calpains and improve tenderness. Feedlot steers (n = 142) were arranged in a 4 x 3 factorial arrangement consisting of four levels of VITD (0, 0.5, 1, and 5 million IU/[steer x d]) for eight consecutive days antemortem using three biological types (Bos in...

Beef cattle from 3 independent studies conducted in the Texas Panhandle (Exp. 1: n = 3,906 and Exp. 2: n = 4,000) and southern Idaho (Exp. 3; n = 542) were used to investigate the association of pro-melanin concentrating hormone (PMCH) genotype with beef carcass quality and yield attributes. Tissue samples were collected from each animal to determine which PMCH allele they expressed (Trial 1: A...

Data from 9 studies were compiled to evaluate the effects of 20 yr of selection for postweaning weight (PWW) on carcass characteristics and meat quality in experimental herds of control Nellore (NeC) and selected Nellore (NeS), Caracu (CaS), Guzerah (GuS), and Gir (GiS) breeds. These studies were conducted with animals from a genetic selection program at the Experimental Station of Sertãozinho,...

An experimental design aiming at analysing the consequences of genetic selection from 1977 to 1998-2000 on the evolution of stress-responsive systems in the French Large White (LW) and Landrace (LR) pig populations was conducted by INRA and IFIP-Institut du Porc. Large White sows were inseminated with semen from LW boars born in 1977 (frozen semen) or in 1998 and their second-generation offspri...

Demands for products of animal origin are increasing worldwide owing to the significant growth in the human population and changes in the health, wealth and life expectancy of people. The agricultural sector has the scientific knowledge, expertise and technology to respond to these challenges, but consumers are concerned about the methods used to meet these new challenges. They are also concern...

The objectives of this experiment were to determine growth performance, visceral mass differences, carcass characteristics, fresh meat quality, and carcass cutability of growing-finishing pigs fed diets containing high-protein canola meal (CM-HP) or conventional canola meal (CM-CV). Seven dietary treatments were fed to investigate effects of increasing inclusion rates of CM-HP or CM-CV in a cor...
