Knowledge of in vivo relationship between the coactivator PPARGC1A and its target genes is very limited, especially in the pig. In this study, a real-time PCR experiment was performed on longissimus dorsi muscle (MLD) and backfat with 10 presumed PPARGC1A downstream target genes, involved in energy and fat metabolism, to identify possible relationships with PPARGC1A mRNA expression in vivo in the pig (n = 20). Except for UCP3 and LPL, a very significant difference in expression was found between MLD and backfat for all genes (P < 0.01). Hierarchical cluster analysis and the significant pairing of mRNA expression data between sampling locations suggested a genetic regulation of the expression of several target genes. A positive correlation with PPARGC1A was found for CPT1B, GLUT4, PDK4, and TFAM(P < 0.0001). A negative correlation was found for UCP2, FABP4, LEP (P < 0.0001), and TNF (P = 0.0071). No significant correlation was detected for UCP3 and LPL. This study provides evidence for a clear difference in mRNA expression of crucial genes in fat and energy metabolism between 2 important tissues. Our data suggest a clear impact of PPARGC1A on energy and lipid metabolism in vivo in the pig, through several of these downstream target genes.

Selected slaughter traits, meat quality and backfat fatty acid profile were assessed in purebred Zlotnicka White (ZW group, n=30) and Zlotnicka Spotted (ZS group, n=30) fatteners (females to castrated males ratio = 1/1). Basic physico-chemical properties were determined in the longissimus dorsi muscle and fatty acid profile was estimated of the backfat. At similar live weight and meat content of carcass in both breed groups, thicker backfat was recorded on the ham of the ZW and on the shoulder of the ZS pigs. The meat of both groups was characterized by good quality.Desirable meat pH, very small juice drip from the muscle tissue, high water holding capacity as well as desirable meat colour were found in both groups, although their indicators were slightly more favourable in ZW. Backfat of the ZW fatteners was found to contain by 2.59 per cent points (pp) more linoleic acid and by 0.38 pp more α-linolenic acid than ZS backfat. However, the ratio of PUFA n-6 to PUFA n-3 in the backfat was similar in both breed groups and amounted to about 10.7

Oceniono wybrane cechy wartości rzeźnej oraz jakości mięsa i tłuszczu słoniny czystorasowych tuczników ras złotnickiej białej i złotnickiej pstrej (Zlotnicka White – ZW i Zlotnicka Spotted – ZS).Oznaczono podstawowy skład chemiczny i wskaźniki fizykochemiczne mięśnia najdłuższego grzbietu i określono profil kwasów tłuszczowych w słoninie grzbietowej. Przy zachowaniu podobnej ubojowej masy ciała i zbliżonej zawartości mięsa w tuszach obu grup grubszą słoninę stwierdzono na szynce świń rasy ZW, natomiast na łopatce – świń rasy ZS. Mięso tuczników badanych ras charakteryzowało się dobrą jakością, a zwłaszcza pożądanym zakwaszeniem, małym wyciekiem naturalnym, dobrą wodochłonnością i pożądaną barwą, przy czym cechy te były nieco korzystniejsze w przypadku świń rasy ZW. Spośród kwasów tłuszczowych, w słoninie świń ZW notowano o 2,59 punktów procentowych (pp) więcej kwasu linolowego i o 0,38 pp kwasu linolenowego. Natomiast stosunek kwasów PUFA n-6 do PUFA n-3 w słoninie obu ras był podobny – około 10.7.

Соответствующие исследования охватывали 719 откормочных хряков и 97 свиноматок купленных в единоличных хозяйствах период зимнего и летнего содержания. Исследования показали, что по мере повышения веса тела откормочных хряков и свиноматок увеличивалась толшина хребтового сала и показатель убойной продуктивности. Анализ времени года показал, что свиноматки и хряки подвергаемые убою в период летнего содержания имели в сравнении с зимним более тонкий шпиг, а показатель убойной продуктивности был выше у свиноматок убиваемых в период зимнего содержания, тогда как у откормочных хряков он был сходным в оба сезона.

The respective investigations comprised 719 fattened loars and 97 sows purchased from private peasant farms in winter and summer maintenance period. The investigations have proved that along with the increasing body weight of boars and sows increased the backfat thickness and the carcass dressing indices. The analysis of the effect of particular seasons on the fattening results proved that the pigs slaughtered in the summer maintenance period were of thinner backfat, while the carcass dressing index was higher in sows slaughtered in the winter maintenance period and in boars was approximate in both seasons.
