The aim of the study was to establish the relationship between a calpastatin gene (CAST) polymorphism, the ryanodine receptor gene (RYR1) polymorphism and carcass/meat quality traits in crossbred pigs. No significant differences in the analyzed pigs were found between genotypes CC and CT at the locus RYR1 and CD and DD at the locus CAST/MspI in terms of carcass and meat quality. However, a sign...

Received: 29/04/2013 Revised: 17/09/2013 Accepted: 23/09/2013 Abstract Accurate prediction of carcass evaluation in live animals may allow more efficient genetic improvement of meat quality. Effective value-based marketing programs require precise techniques for assessing composition, palatability and other factors associated with consumer acceptance of meat products. The ultimate test for a ca...

This experiment was carried out to study the effect of the inclusion of a yeast culture in the diet of feeder dairy calves on their growth and carcass characteristics. Thirty male Friesian calves were randomly allocated to two groups of 15 each (treatment and control). The calves were fed a total mixed ration for a period of 294 days and then slaughtered to obtain carcass measurements. The yeas...

Innovations in beef carcass fabrication to improve subprimal yield, retail cut yield, and overall carcass value were evaluated. Alternating sides from 30 beef carcasses were assigned to either an innovative or conventional style of fabrication. The innovative method resulted in greater (P<0.001) total subprimal yield and less (P<0.001) lean trimmings from the forequarter; however, hindquarter t...

A chromogenic Limulus amoebocyte lysate (LAL) endpoint assay was found to be an accurate and rapid means of gauging levels of beef carcass microbial contamination within 10 min. The assay demonstrated a high correlation with the total mesophilic bacterial and coliform surface populations from inoculated beef carcass surface tissues. This assay was tested on a set of actual beef carcass surface ...

Near-infrared (NIR) interactance was evaluated as a potentially new method for estimating live body and carcass composition of pigs. Using a surface placed fiber optic probe, measurements of the live animal and carcass were made on a total of 120 pigs. These measurements were compared with lipid and protein content of soft tissue dissected from the pig carcass. NIR results were evaluated using ...

To investigate the relationship between chemical composition of meat from the carcass cuts and thewhole carcass, 48 nine-month-old randomly selected ram lambs of Ghezel and Mehraban (24 rams per breed)were used in a trial arranged as a 2 × 2 factorial experiment with two breeds and two feeding levels (high andlow), in a completely randomized design. After 80 days, all animals were slaughtered a...

The current study was conducted to investigate the effects of genetic and non-genetic factors on body weight and carcass traits of Japanese quails. Two strains of Japanese quail (150 wild quails and 150 white quails) were used as base population. Four mating groups were used to produce progenies: wild male × wild female, white male × wild female, wild male × white female and white male × white ...

The effect of genotype, sex and hatch on carcass traits and physical characteristics of eggs was investigated in the Japanese quail. Two strains of Japanese quails including the White (P1) and Wild (P2) genotypes were chosen as the parental generation and crossed reciprocally (10 singlepair mating) to create the F1 progeny. The F1 birds (27 males and 81 females) were mated randomly to produce t...

OBJECTIVE This experiment was conducted to investigate the effects of crude glycerin from waste vegetable oil (CGWVO) on performance, carcass traits, meat quality, and muscle chemical composition. METHODS Twenty-four crossbred (Thai Native×Anglo Nubian) uncastrated male goats (16.8± 0.46 kg body weight [BW]) were assigned to a completely randomized design and subjected to four experimental di...
