Um Leistungsniveau, systematische Effekte und phänotypische Korrelationen zu schätzen, wurden bei 276 Weidekälbern verschiedener Genotypen aus der Mutterkuhhaltung (Material I) Merkmale der Fleischleistung und der Fleisch¬qualität erfasst und ausgewertet. Neben den Identitäts- und Lebensdaten der Tiere wurden die folgenden Merkmale der Fleischleistung einbezogen: Alter beim Schlachten, Lebendgewicht, Lebenstagszunahme, Schlachtkörper¬gewicht, Nettozunahme sowie die Komponenten der Handelsklasse, also Fleischigkeitsklasse und Fettgewebeklasse. / In order to estimate performance level, systematic effects and phenotypic correlations, characteristics of meat performance and meat quality were recorded and analysed in 276 weaning calves of different genotypes from cow-calf operations (material I). In addition to identity and basic life data, the following characteristics of meat performance were included: age at slaughter, live weight, daily gain, carcass weight, net gain as well as the components of the carcass grade, grade for meatiness and grade for fat¬ness. The following characteristics of meat quality were measured on the meat probes 48 hours and 14 days resp. after slaughter: pH-value (pH1, pH2), meat colour with lightness L* (L*1, L*2) redness a* (a*1, a*2) and yellowness b* (b*1, b*2), Warner-Bratzler shearforce raw (WBS1, WBS2) and cooked (WBS3) as well as intramuscular fat content (IMF).
