“…There were no differences between stocking densities for most carcass quality traits, including slaughter weight, hot and cold carcass weights, backfat thickness at two points, and meatiness (P >0.05). Similar results were reported by Guise et al (1998) and Nanni Costa et al (2002), who did not find evidence that transport stocking density had an impact on the carcass quality parameters.…”

The aim of this study was to determine the effects of gender, slaughter weight, stocking density, lairage time and season on carcass and meat quality parameters in a low-input production system. The study was conducted on 400 slaughter pigs (200 barrows and 200 gilts) with live weight of 115.0 ± 4.70 kg. Barrows had higher slaughter and carcass weights, fat thickness and lower meatiness. Heavier pigs had higher hot and cold carcass weights, fat thickness, lower meatiness, and higher incidences of pale, soft and exudative (PSE) and dark, firm and dry (DFD) meat. Low stocking density during transportation increased skin lesion score, pH 45 value and the incidence of DFD meat; while high stocking density decreased pH 45 value and increased T 45 value and the incidence of PSE meat. Long lairaging reduced slaughter weight, carcass weight, dressing percentage and backfat thickness and increased skin lesion score. After overnight lairaging, pH 45 value and the incidence of DFD meat became higher. After short lairaging, the pH 45 value was lower, while the incidence of PSE meat increased. Pigs slaughtered in winter had the highest slaughter weight, backfat thickness, pH 45 value and incidence of DFD, and the lowest meatiness. Pigs slaughtered in summer had the lowest slaughter and carcass weights and pH 45 value, and the highest incidence of PSE meat. In conclusion, gender influenced carcass quality, slaughter weight and lairage time, and season affected carcass and meat quality, while stocking density had an impact on meat quality.

“…On the basis of measurements of the space needed for sternal recumbence and direct observations of pigs at different stocking densities, Warriss (1998a) reported that the minimum space required was equivalent to about 250 kg/m 2 for normal slaughter pigs of 90 to 100 kg live weight. Guise et al (1998) found no evidence that the transport stocking density affected the carcass quality or welfare of 95-kg pigs on short journeys (3 h). Kim et al (2004) detected a lower concentration of stress hormones in the low-density group than in the medium-or high-density group.…”

The study monitored the effect of the housing system and the number of animals transported together on transport-induced mortality of slaughter pigs in the Czech Republic in the period from 2004 to 2008. Concerning the type of housing during the fattening, the lowest mortality rate during the subsequent transport to slaughter houses was detected among pigs fattened on solid floor (0.047%) and on deep bedding (0.084%). The highest mortality during transport was detected among pigs fattened on fully or partially slatted floor (0.139%), a significant difference (p < 0.01) was found compared to other housing types. Assessment of the influence of individual pig load size on mortality showed the lowest mortality among pigs transported in loads of up to 40 animals (0.053%). Mortality during the transport in loads of the size of 41 to 120 animals was 0.130%, and for loads of the size over 120 pigs the mortality rate was 0.156%. These mortality rates are significantly higher (p < 0.01) compared to the load sizes of up to 40 animals.

“…A utilização do gene halotano em programas de genética suína ainda é um assunto muito controvertido entre os pesquisadores da comunidade científica internacional, porém parece haver um consenso de que o incremento em carne magra proporcionado por este gene deprime as caracterís-ticas qualitativas da carne [9,14,16,18,23,22,35].…”

resumoSuínos provenientes de três linhagens genéticas A, B e C comercializadas no Brasil, com peso vivo de 100 a 120 kg foram submetidos ao insensibilizador elétrico manual (45)(46)(47)(48)(49)(50)(51)(52)(53)(54)(55)(56)(57)(58)(59)(60) Hz e 1,4 -1,5 A) e ao sistema gasoso coletivo (COMBI-BUTINA 90% CO 2 ). Alíquotas sanguíneas, para determinação dos níveis de creatina fosfoquinase (CPK), lactato e cortisol, assim como amostras do músculo semimembranosus (10 g) para a determinação do gene halotano, foram coletadas. Comparando-se os sistemas de insensibilização elétrico e gasoso (CO 2 ), o elétrico demonstrou ser mais estressante, proporcionando maiores concentrações plasmáticas de cortisol (p ≤ 0,001) e lactato (p ≤ 0,001) para as linhagens genéticas A e C, nas condições estudadas, porém não se observou diferenças significativas para os indicadores sanguíneos e sistemas de insensibilização em questão quando a linhagem B foi considerada. Diferenças significativas entre as linhagens genéticas A, B e C foram obtidas comparando-se os valores plasmáticos de creatina fosfoquinase (p ≤ 0,001), lactato (p ≤ 0,001) e cortisol (p ≤ 0,001) quando atordoados com o sistema gasoso, entretanto, quando o sistema elétrico foi utilizado, somente os valores de cortisol apresentaram diferenças significativas (p ≤ 0,001). A presença do gene halotano (Nn) foi observada somente na linhagem B.

PART 1 -BLOOD STRESS INDICATORS.Pigs of three genetics lineages A, B and C marketed in Brazil, with alive weight from 100 to 120 kg were submitted to the manual electric stunning (Karl Schermer 220-230/250 volts, 45-60 Hz and 1.4 -1.5 A) and to the collective gaseous system (COMBI-BUTINA 90% CO 2 ). Blood samples, for levels determination of creatine phosphokinase (CPK), lactate and cortisol, as well as samples of the semimembranosus muscle (10 g) for the determination of the gene halothane, were collected. Being compared the electric and gaseous stunning systems, the electric stunning did demonstrate to be more stressful providing larger plasmatic concentrations of cortisol ( p ≤ 0.001) and lactate ( p ≤ 0.001) for the genetic lineages A and C, in the studied conditions. However it didn't observe significant differences beween the sanguine indicators and stunning systems in subject when the lineage B was considered. Significant differences among the genetic lineages A, B and C were obtained being compared the plasmatic values of creatine phosphokinase (p ≤ 0.001), lactate (p ≤ 0.001) and cortisol (p ≤ 0.001) when stunned with the gaseous system, however when the electric system was used only the cortisol values presented significant differences (p ≤ 0.001). The presence of the gene halothane (Nn) was only observed in the lineage B.
