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 objective of this study was to compare fattening performance, carcass traits, and egg quality of Japanese quails with different feather colors (white, dark brown, golden, and wild-type). In the study, 360 one-day-old quail chicks with 4 different feather colors were used as animal material. Quails were fed ad libitum for 42 days to determine fattening performance and carcass traits. To dete...

Effects of a supplemental fermented agro by-products diet on growth performance, blood characteristics and carcass traits were investigated in fattening pigs. The fermented diet mainly contained 38.0% brewer’s grain, 25.0% rice bran and 21.0% byproduct of king oyster mushrooms. The mixed ingredients were fermented at 40°C for 7 days and fed to crossbred barrow pigs for 62 days. Ninety pigs were...

The objective of this study was to determine whether increasing levels of dietary safflower oil would alter unsaturated fat (especially CLA) and tocopherol content of lamb, animal performance, carcass characteristics, or color stability of lamb muscle tissue. Targhee x Rambouillet wethers (n = 60) were assigned to one of three diets (four pens per treatment with five lambs per pen) in a complet...

Finding alternative feeds, such as sesame hulls and Prosopis juliflora species can attenuate difficulties of feed shortage and reduce the cost of animal feed in arid and semi-arid countries. Thirty-two Black male kids with similar initial weights (BW = 16.7±0.80 kg) and 120±5 d of age, were used to evaluate the effect of replacing barley grains and soybean meal with Prosopis juliflora pods (PJP...

Sixty-four crossbred heifers (451 +/- 23 kg) were used in a 42-d feeding trial (4 pens per treatment in a randomized complete block design) to evaluate the influence of preslaughter zilpaterol hydrochloride withdrawal period on growth performance and carcass characteristics. Heifers were fed a diet based on steam-flaked corn (2.13 Mcal of NE(m)/kg). Treatments were 1) control, no zilpaterol sup...

Pigs from the F(2) generation of a Duroc x Pietrain resource population were evaluated to discover QTL affecting carcass composition and meat quality traits. Carcass composition phenotypes included primal cut weights, skeletal characteristics, backfat thickness, and LM area. Meat quality data included LM pH, temperature, objective and subjective color information, marbling and firmness scores, ...

An experiment was conducted to assess the effect of dietary supplementation of garlic (Allium sativum) and fenugreek (Trigonella foenum-graecum L.) seed powder as herbal feed additives on growth performance, carcass characteristics and economics of feeding in broilers. A total of 320 day old broiler chicks of Cobb-400 strain were divided into four treatment groups with 4 replicates of 20 chicks...

The growth performance and the carcass and physical and chemical characteristics of the meat of 24 Landrace X Large White pigs were compared when reared under a free-range or a conventional housing system. The free-range pigs had lower feed intakes and slower growth rates than the conventionally housed pigs. The free-range pigs also had a lower P2 fat depth and therefore yielded a carcass with ...

An experiment was conducted to examine the effects of different pre-starter diets on the performance, digestive organs and carcass characteristics of broilers. One hundred and fifty day-old broiler chicks were divided into five groups with three replicates having ten chicks each. During first ten days the birds were fed on five experimental pre-starter diets formulated with different metaboliza...
