The objective of this study was to evaluate the effect of vaccination against gonadotropin-releasing factor (GnRF) on carcass characteristics and meat quality and back fat quality. In total, 400 healthy male pigs were randomly assigned into two treatment groups: physically castrated males (CM) and vaccinated males (IM). CM pigs were physically castrated within 3 days of age. IM pigs received the GnRF vaccine twice, at 14 and 21 weeks of age. At the end of the experiment, 20 pigs of each treatment were weighed individually and slaughtered at 25 weeks of age. The longissimus muscle was collected to evaluate the meat quality including pH, drip loss, shear force, cooking loss, intramuscular fat, fatty acid composition and inosine monophosphate. Subcutaneous fat was sampled to evaluate fatty acid composition. IM pigs had a lower dressing percentage and were leaner (P < 0.01). The inosine monophosphate content was higher in pork from IM pigs than from CM pigs (P < 0.05). IM pigs had a higher content of polyunsaturated fatty acids in longissimus muscles than CM pigs (P < 0.01), mostly because of the higher linoleic acid content (P < 0.01). IM pigs had higher levels of unsaturated fatty acids in subcutaneous fat than CM pigs (P < 0.01), mostly because of the higher linoleic acid and linolenic acid (P < 0.01) and the lower myristic acid content (P < 0.01). There were no adverse effects of the GnRF vaccine on slaughter performance and meat quality of pigs. These results suggest that GnRF vaccine administered to pigs increases the inosine monophosphate content in longissimus muscles and the content of polyunsaturated fatty acids in longissimus muscles and back fat. Consequently, vaccination with Improvac for boar taint control will provide a good alternative to physical castration of male pigs.

The study aimed at an evaluation of fattening and slaughter performance as well as meat quality of the native Złotnicka Spotted (ZS) pigs and its crosses with Duroc pigs. The experimental material comprised 60 fatteners, divided into three genetic groups of 20 animals (100% ZS, 75% ZS and 50% ZS). The specific character of conservative breeding results in low values of fattening and slaughter performance traits observed in ZS breed. Among the analysed groups, animals with 100% share of ZS genes in their genotype were characterised by low daily weight gains (0.59 kg), considerable backfat thickness (34.96 mm), slight muscle thickness (48.05 mm), and low leanness (41.83%). These parameters were higher in both groups of crosses. Differences between the 100% ZS group and the 50% ZS group were significant for backfat thickness and highly significant for leanness. Acidity and colour parameters analysis showed that meat from all the genetic groups analysed was characterised by a good quality. The highest pH<sub>45 </sub>values were in the 75% ZS group, and meat from this group had the darkest colour (L* = 49.73) and the highest red colour share (a*&nbsp;=&nbsp;5.11). Statistical analyses showed that ZS breed retained its original traits through the years of breeding. It was confirmed that meat of Złotnicka Spotted breed is characterised by excellent quality. The results indicate that ZS and Duroc breeds crossing improves fattening and slaughter performance, while maintaining good meat quality in their crosses. Results of this study may also be used by breeders. They indicate that crosses of both the breeds kept in extensive breeding may be successfully used in high quality meat production. Pork from such animals may be a raw material for market niche production, such as regional products. The use of meat from crosses in meat processing may improve both quality of the processed products and efficiency of production based on the native Złotnicka Spotted breed. &nbsp;

Abstract. Title of the paper: Fattening, slaughter performance and meat quality of different pig breeds in indoor or outdoor housing (short communication) Relationships between outdoor housing and some meat quality parameters were investigated. Studies were carried out with the pig breeds Schwerfurter Fleischrasse, Deutsches Sattelschwein und Duroc. Fattening, slaughter performances and meat quality were compared by indoor or outdoor housing. Between different breeds in most parameters there were significant differences. Regarding the influence of outdoor housing with grazing the study showed improve results by meat quality parameters only in meat colour and water keeping.
