Carcass and meat quality traits of pig fatteners from Slovenian Breeding programme
Maja Prevolnik, Martin Škrlep, Dejan Škorjanc, Marjeta Čandek-Potokar, 2008, published scientific conference contribution

Abstract: The aim of the present study was the comparison of carcass and meat quality traits of commercial pigs of various crossbreeds from two major Slovenian herds. The analysis is based on phenotypic data from field trials which have been collected in the last past five years within the Slovenian breeding programme. Important differences in carcass traits were observed between two herds and were associated to different crossbreeds used. In spite of that economically important result on the slaughter line (lean meat %) was similar for both herds. Meat quality traits were also significantly different between the two herds. Again, the difference could be ascribed to crossbreeds used. However, since the herd effect is connected with abattoir effect, different ante-mortem conditions and/or lower robustness of these animals to premortal stress could also be contributed to the observed differences. The presented results give important information on the state-of-the-art regarding meat quality of Slovenian pigs.

Abstract: Immunocastration is a sustainable alternative to piglet castration but faces limited market acceptance. The phenomenon of non-responders has not to date been examined in detail, but adverse and stressful housing conditions (e.g., mixing of groups) might impair the success of vaccinations. Therefore, we evaluated the influence of housing conditions on the immune response after two Improvac® vaccinations at an age of 12 and 22 weeks, respectively. Boars, immunocastrates and barrows (n = 48 each) were assigned to three different housing conditions (n = 36 enriched, n = 36 standard n = 72 repeated social mixing). Immune response was quantified by measuring GnRH-binding and its consequences for testosterone concentrations, development of the genital tract and boar taint. Growth performance was evaluated via average daily gain (ADG). GnRH-binding and testosterone levels revealed that immunocastration reliably suppressed testicular functions after the 2nd vaccination. Housing conditions did not modify testicular function but influenced ADG as animals under mixing grew slower than those under enriched conditions. Gonadal status had only a slight impact on ADG except in immunocastrates, which showed a temporarily higher ADG after the 2nd vaccination. The results show that immunocastration is a reliable procedure under different housing conditions and competitive in terms of growth performance.
