“…This indicates that sex may, to some extent, modulate the effect that some of the factors relative to the physical environment have on performance. Genotype also determines behaviour and performance of pigs, and the Duroc breed is known, amongst other things, for its elevated feed intake values (McGloughlin et al, 1988;Edwards et al, 1992). In the present study the Duroc, Duroc 3 Pietrain and Duroc 3 Hampshire crosses showed high percentages of total time spent eating, indicating that genetic differences in performance may, at least partly, be explained by behavioural differences.…”

A meta-analysis, using information from 45 experiments on growing-finishing pigs published in 39 manuscripts, was carried out to determine the simultaneous effects of the physical environment (space allowance, group size, flooring conditions, temperature, presence of enrichment), pig traits (initial body weight (BW) for each studied time interval, sex, genetics), feeder characteristics (water provision within the feeder, feeder design (individual/collective), feeder places/pig, presence of feeder protection) and feed characteristics (feed allowance (ad libitum/restricted), net energy content, crude protein (CP) content), as well as their potential interactions, on the feeding behaviour and performance of growing-finishing pigs. The detrimental effect of low temperature on performance was particularly evident for restricted-fed pigs (P< 0.05). At reduced feeder space allowance, a reduction in the percentage of time spent eating was predicted when increasing initial BW, whereas the opposite was predicted for larger feeder space allowances (P< 0.001). The reduction in visit duration to the feeder in higher BW groups became gradually more important with increasing feeder space allowance (P< 0.01), whereas the increase in the ingestion rate and average daily feed intake (ADFI) with increasing initial BW became smaller with increasing feeder space (P< 0.05). The model predicted a reduction in feed conversion ratio (FCR) with increasing group size (P< 0.05) and floor space allowance (P< 0.01) and on solid floors with or without bedding (P< 0.05). In comparison with other feeders, wet/dry feeders were associated with more frequent but shorter feeder visits (P< 0.05), higher ingestion rates (P< 0.001) and higher ADFI (P< 0.10). The use of protection within individual feeders increased the time spent feeding (P< 0.001), reduced the number of visits per day (P< 0.01), the ingestion rate (P< 0.001) and FCR (P< 0.01) in comparison with other feeder types. Sex modulated the effect of the number of feeder places/pig on FCR (P< 0.05), with a gradual reduction of FCR in entire males and females when increasing feeder space allowance. Genetics tended to modulate the effect of diets’ CP content on FCR (P< 0.10). Overall, these results may contribute to the improvement of the welfare and performance of growing-finishing pigs by a better knowledge of the influence of the rearing environment and may help optimize the feeding strategies in current production systems.

“…Sabbioni et al (2002) found that Duroc genes determined thicker backfat at shoulder level, but had no effect on the carcass composition. Instead, McGloughlin et al (1988) and Channon et al (2004) reported no differences in fat thickness, while for Affentranger et al (1996) and Enfält et al (1997) Duroc sire determined more fat in back and in ham than Large White or Yorksire ones. The variability of these results is confirmed in other researches that assessed the differences among Duroc genetic lines, as it regards carcass fatness (Cilla et al, 2006;Ramirez and Cava, 2007) and it must be reminded that Duroc breed employed in the present experiment is the line selected for the typical Italian heavy pig production, where no particular emphasis against the subcutaneous fat is applied (ANAS, 2010).…”

“…Comparisons for growth rate between Duroc and Large White, always tested in indoor rearing, are widely reported in literature with conflicting results. Better performance in progeny of Duroc boar than in that of LW boar was noted by McGloughlin et al (1988) and Franci et al (1994), up to 85 and 160 kg, respectively; Sabbioni et al (2002) found a negative effect of the contribution of Duroc genes on LW up to 120 kg but positive afterwards; Liu et al (1999) reported no significant differences in growth rate between Duroc and LW, both as pure-bred or crossbred. Table 2 reports carcass measurements and composition.…”

The objective of this work was to evaluate, under indoors and outdoors rearing, the effect of crossing Cinta Senese (CS) with Italian Large White (ILW) and Italian Duroc (ID) breeds. Starting from 72 d of age, 9 CS, 8 ILWxCS and 7 IDxCS were reared outdoors (OUT) in 3 paddocks of 2 ha and 8 CS, 10 ILWxCS and 8 IDxCS pigs were reared indoors (IN) in three pens of 20 m 2 . All pigs, fed the same commercial diets, were weighed and measured periodically and were slaughtered at a target live weight of 150 kg. Indoor-pigs grew faster than the outdoor ones and crossbred pigs showed higher average daily gain than CS breed (476, 437 and 387 g/d for IDxCS, ILWxCS and CS, respectively). Rearing system had moderate or null effect on carcass and sample cut composition whereas the OUT pigs, when compared to IN ones, showed higher moisture and lower IMF in Longissimus L. and Psoas M. muscles and higher cooking loss of meat (22.1 vs 18.4 %) that resulted also less red (a* 10.94 vs 12.04). CS had more fat in carcass and more bone in sample cut than the crossbreeds. ILWxCS showed lower IMF content and higher moisture in muscles and brighter and less red meat than the other breeds, while IDxCS produced the most tender meat after cooking. The use of Italian Duroc could be profitable on Cinta Senese to improve the farming performance without worsening the fresh meat quality.

“…No significant effect of the sire on muscle acidity was recorded either at 1 and 24 hours after slaughter. In many studies conducted in different countries it was shown that Duroc is one of the few breeds, which in matings with other breeds yield a marked effect of heterosis in the most significant productivity parameters [4,8]. We also need to stress the fact that even under inferior environmental conditions crosses with this breed exhibit better daily body weight gains and feed conversion rates than purebred animals, which may indicate their higher adaptability.…”

Experimental material consisted of 112 carcasses of crossbred fatteners (złp x dur) and 16 purebred animals (złp). The following traits were analyzed in postslaughter evaluation: carcass weight (kg), mean backfat thickness (mm), height of the longissimus dorsi muscle (mm) and lean meat percentage in the carcass (%). Based on the determined carcass weight and measurements of carcass leanness the carcasses were classified in the SEUROP system. Results of postslaughter evaluation indicate relatively low carcass leanness. In only 10% carcasses leanness exceeded 50 %, while 75% carcasses fell within the range from R to O in the EUROP classification. The breed of the sire had a highly significant effect on meatiness of fatteners. Pigs sired by Duroc boars were characterized by a significantly higher meatiness, irrespectively of sex, piggery, supplier and year of birth. Backfat thickness was significantly higher in the group of crosses sired by Złotnicka Spotted boars.Keywords: pig; Złotnicka Spotted; fattening; lean meat percentage Abstrakt Materiał badawczy stanowiło 112 tusz tuczników mieszańcowych (złp x dur) oraz 16 osobników czystorasowych (złp).
