ABSTRACT.
The objective of this study was to estimate the genetic?quantitative relationships between the beef fatty acid profile with the carcass and meat traits of Nellore cattle. A total of 1826 bulls finished in feedlot conditions and slaughtered at 24 months of age on average were used. The following carcass and meat traits were analysed: subcutaneous fat thickness (BF), shear force (SF) and total intramuscular fat (IMF). The fatty acid (FA) profile of the Longissimus thoracis samples was determined. Twenty-five FAs (18 individuals and seven groups of FAs) were selected due to their importance for human health. The animals were genotyped with the BovineHD BeadChip and, after quality control for single nucleotide polymorphisms (SNPs), only 470,007 SNPs from 1556 samples remained. The model included the random genetic additive direct effect, the fixed effect of the contemporary group and the animal?s slaughter age as a covariable. The (co)variances and genetic parameters were estimated using the REML method, considering an animal model (single-step GBLUP). A total of 25 multi-trait analyses, with four traits, were performed considering SF, BF and IMF plus each individual FA. The heritability estimates for individual saturated fatty acids (SFA) varied from 0.06 to 0.65, for monounsaturated fatty acids (MUFA) it varied from 0.02 to 0.14 and for polyunsaturated fatty acids (PUFA) it ranged from 0.05 to 0.68. The heritability estimates for Omega 3, Omega 6, SFA, MUFA and PUFA sum were low to moderate, varying from 0.09 to 0.20. The carcass and meat traits, SF (0.06) and IMF (0.07), had low heritability estimates, while BF (0.17) was moderate. The genetic correlation estimates between SFA sum, MUFA sum and PUFA sum with BF were 0.04, 0.64 and −0.41, respectively. The genetic correlation estimates between SFA sum, MUFA sum and PUFA sum with SF were 0.29, −0.06 and −0.04, respectively. The genetic correlation estimates between SFA sum, MUFA sum and PUFA sum with IMF were 0.24, 0.90 and −0.67, respectively. The selection to improve meat tenderness in Nellore cattle should not change the fatty acid composition in beef, so it is possible to improve this attribute without affecting the nutritional beef quality in zebu breeds. However, selection for increased deposition of subcutaneous fat thickness and especially the percentage of intramuscular fat should lead to changes in the fat composition, highlighting a genetic antagonism between meat nutritional value and acceptability by the consumer.

Summary: As part of an international project, the consumer acceptance of Uruguayan and German beef and lamb was examined. Two groups of consumers from two German district towns (Kulmbach, Vechta ? n = 100 each) were consulted. The meat samples originated from the respective breeds prevailing in each country, and from pasturing (Uruguay) or from high level feeding (Germany). Between the consumer judgements about Uruguayan and German samples, no salient differences exist if the meat is sufficiently aged. The lamb was judged surprisingly well, although 65 % of the consumers indicated never to consume lamb. Ageing for 20 days is essential particularly for beef, since the consumers detected a significant reduction in quality after a seven days ageing period. Noticeably, higher fat content was linked with better sensory classification at both meat types. Cluster analyses of judgements revealed that the overall acceptability of beef depends more on tenderness; in the case of lamb, it is determined more by flavour. According to age groups, the consumers evaluated the samples significantly different: The group of elderly rated more tolerantly than the other groups. // Zusammenfassung: Als Teil eines internationalen Projektes wurde die Verbraucherakzeptanz von uruguayischem und deutschem Rind- und Lammfleisch untersucht. Hierzu wurden zwei Verbraucherstichproben in zwei deutschen Kleinstädten (Kulmbach, Vechta ? je n = 100) herangezogen. Die
Fleischproben stammten von jeweils landesüblichen Rassen und aus Weidehaltung (Uruguay) bzw. Intensivmast (Deutschland). In der Bewertung der uruguayischen und deutschen Proben werden von den Verbrauchern keine markanten Unterschiede festgestellt, sofern das Fleisch ausreichend gereift wird. Das Lammfleisch wurde überraschend gut beurteilt, obwohl 65 % der Verbraucher angaben, nie Lammfleisch zu verzehren. Bei Rindfleisch ist die Reifung von 20 Tagen unerlässlich, da die Verbraucher eine signifikante Qualitätsbeeinträchtigung nach einer Reifungszeit von lediglich 7 Tagen feststellen. Bei beiden Fleischtypen wurde höherer Fettgehalt mit besserer sensorischer Einstufung verbunden. Mit Hilfe von Clusteranalysen der Prüfurteile wurde belegt, dass bei den Rindfleischproben der Gesamteindruck stärker von der Zartheit, bei den Lammfleischproben stärker vom Aroma bestimmt war. In Abhängigkeit vom Alter bewerteten die Verbraucher die Proben signifikant unterschiedlich: Die älteste Gruppe bewertete toleranter als die anderen Gruppen.
