Pigs and dairy cows are the two main industries of livestock production in the Czech Republic (CR) and in the European Community (EC) as a whole. Of the total annual per capita meat consumption in the CR (81 kg), in the EC (92 kg) and worldwide (42 kg) pig meat accounts for 54% (43.5 kg), 47% (42.7 kg) and 39% (16.4 kg), respectively. Longterm forecasts indicate that the production and consumption of pig meat in the EC will slowly grow by about 3% to 4% by 2013. In accordance with the common agricultural policy reform, which is in the process of realization, increased attention will be paid to food production. Consequently, issues associated with the identification, classification and quality of pig carcasses will be of increased importance.According to Kirton (1989) pig classification is the most objective of the various systems applied to pig, sheep and cattle carcasses, because it is the animal to which it is easiest to apply objective classification methods. One reason for this is that it has more uniform fat cover than other species.The conventional method of pig carcass classification (FOM, SKG II) was analysed by Matzke et al. (1986), the AutoFOM system based on ultrasonic measurements was described by Brøndum et al. (1998), Busk et al. (1999), and the accuracy of FOM instruments used in on-line pig carcass classification in the CR was detailed by Šprysl et al. (2007) and others.The accuracy of the EU reference dissection method for pig carcass classification in four dif- The highest correlation coefficients are between QC and LM (r = -0.920), LM and FT (-0.900) as well as QC and FT (0.828), the lowest between FT and MT (r = -0.084). Quality class as the dominant indicator is influenced mainly by LM, which explains from 77% to 89% of variability in the case of linear regression. Among the eight methods of pig carcass classification the FOM apparatus was used the most frequently (46.5% carcasses) followed by the ULTRA-FOM 300 apparatus (15.6%), another apparatus (13.2%) and by the IS-D-05 unit (9.8%). In the statistical models used all effects (differences) are statistically significant because of the large size of the data set. The results from the separate evaluation of each cross-classified effect are that EV has the largest influence and yearseason and methods have a smaller influence. The time trend (42 months) documents stable CW and MT, a slight increase in LM and improvement of QC. The estimated results indicate the successful introduction of pig carcass classification in the CR after accession to the EU.

The aim of the research was to assess the quality indicators of pork from two or three pedigree pig hybrids imported from Denmark during industrial feeding. 3 groups of piglets were formed, 20 heads each at the age of 2 months. In the course of the research, zootechnical, biochemical, physicochemical and mathematical methods of analysis were used. The resulting digital material was processed by the method of variational statistics, taking into account the Styudent’s confidence criterion, using the software package Mikrosoft Excel. It was found that the two and three breed hybrids were characterized by high gains in growth, and reached 100 kg of live weight earlier than pure breed analogs of the Landrace breed. Their carcasses also contained more muscle tissue by 1.0 and 1.7%, the ratio of muscle tissue to fat tissue was higher by 0.16 and 0.29%, respectively. Pork obtained from two and three breed hybrids contained more tryptophan and oxyproline in comparison with purebred animals which may indicate its greater biological value. Thus, meat raw materials obtained from two- and three-breed hybrids during industrial cultivation are leaner in comparison with purebred animals, which is preferable for food production.

“…Various approaches in the studies of body composition based on repeated crosssectional MR images can be found in literature [70][71][72]. Kusec et al [73] investigated influence of MHS genotype and feeding regime by the examination of live Authors found that the intensive feeding regime did not improve muscle growth of hybrid pigs and that the more cost-effective restrictive feeding can be considered as more appropriate in pig fattening.…”

Regional markets require a large variety of pig breeds and pork products. Noninvasive techniques like computed tomography, magnetic resonance imaging, dual-energy X-ray absorptiometry, computer vision, or, very often, ultrasound helps to provide the information required for breeding, quality control, payment, and processing. Meanwhile, computed tomography is being used as phenotyping tool by leading pig breeding organizations around the world, while ultrasound B- or A-mode techniques belong to the standard tools, especially to measure subcutaneous fat and muscle traits. Magnetic resonance imaging and dual-energy X-ray absorptiometry, however, are still mainly used as research tools to develop and characterize new phenotypic traits, which usually could not be measured without slaughtering the breeding pigs. A further noninvasive method—already used on a commercial basis, not only in abattoirs—is video 2D or 3D imaging. This chapter will review the latest developments for these noninvasive techniques.
