Summary<\/span>
Objective of the study was to evaluate the influence of time point of second vaccination with the GnRH analogon Improvac\u00ae on growth performance, carcass quality and fatty acid composition of male fatteners compared to surgically castrated pigs and entire boars. The pigs (Pi\u00e9train-crossbreds) were divided into two vaccination groups with first GnRH vaccination at eleven weeks of age and second vaccination at 21 (group IA, n = 84) or 18 weeks (IB, n = 83) of age, one group with surgically castrated males (C, n = 90) and one with entire males (EM, n = 91). Body weight, feed conversion rate, carcass quality and fatty acid composition in back fat were estimated. Feed conversion rate until second vaccination was better (P lt; 0.05) in the vaccination groups (1:2.39) and in group EM (1:2.34) than in group C (1:2.55). Carcass weight did not differ between the groups. Vaccination groups had significantly (P lt; 0.01) leaner meat (IA: 58.9%, IB: 58.3%) and less back fat (IA: 14.6 mm, IB: 15.5 mm) than group C (56.5%, 17.1 mm). Fatty acid composition was shifted to polyunsaturated fatty acids (PUFA) in back fat in vaccination groups and EM compared to C. The time lag between second vaccination and slaughter had no influence on growth performance, feed intake and carcass quality. C18:3 and C20:2 were significantly (P lt; 0.01) higher in group IB than in IA, but PUFA did not differ between vaccination groups. GnRH vaccinated fatteners were economically superior to surgically castrated in this study. <\/p>

Ziel der Studie war, den Einfluss des Zeitpunktes der zweiten Impfung mit dem GnRH-Analogon Improvac\u00ae auf Mastleistung, Schlachtk\u00f6rperqualit\u00e4t und Fetts\u00e4uremuster m\u00e4nnlicher Mastschweine im Vergleich zu intakten Ebern und Kastraten zu ermitteln. Die Studientiere (Pi\u00e9train-Masthybriden) wurden in zwei Impfgruppen mit der ersten GnRH-Vakzination in der elften Lebenswoche und der zweiten Impfung in der 21. (IA, n = 84) bzw. 18. (IB, n = 83) Lebenswoche, eine Gruppe mit chirurgisch kastrierten (C, n = 90) und eine mit intakten m\u00e4nnlichen Mastschweinen (EM, n = 91) eingeteilt. K\u00f6rpermasse, Futterverwertung, Schlachtk\u00f6rperqualit\u00e4t und Fetts\u00e4uremuster im R\u00fcckenfett wurden gemessen. Die Futterverwertung bis zur zweiten Vakzination war in den Impfgruppen (1:2,39) und in Gruppe EM (1:2,34) besser (p lt; 0,05) als in Gruppe C (1:2,55). Das Schlachtgewicht unterschied sich zwischen den Gruppen nicht. Die Impfgruppen hatten einen signifikant (p lt; 0,01) h\u00f6heren Magerfleischanteil (IA: 58,9 %, IB: 58,3 %) und weniger R\u00fcckenfett (IA: 14,6 mm, IB: 15,5 mm) als Gruppe C (56,5 %, 17,1 mm). Das Fetts\u00e4uremuster war in den Impfgruppen und in Gruppe EM, verglichen mit Gruppe C, in Richtung mehrfach unges\u00e4ttigte Fetts\u00e4uren (PUFA) verschoben. Der Abstand der zweiten Impfung zur Schlachtung hatte keinen Einfluss auf Mast- leistung, Futteraufnahme und Schlachtk\u00f6rperqualit\u00e4t. Einige PUFA (C18:3, C20:2) waren in Gruppe IB signifikant (p lt; 0,01) h\u00f6her als in IA, wohingegen sich die Summe der PUFA zwischen den Impfgruppen nicht unterschied. GnRH-geimpfte Mastschweine waren den chirurgisch kastrierten Schweinen hinsichtlich \u00f6konomischer Aspekte in dieser Studie \u00fcberlegen. <\/p>
