The aim of this study was to derive economic weights for sheep breeding goal traits specific cluster types. herd clustering approach considered 25 German herds including descriptors related area-based factors, management information and socio-economic characteristics. evaluation criterion suggested the application agglomerative hierarchical with respective allocation 3 different clusters. clusters mainly differed regard size, production focus, organic versus conventional practices. ongoing contingent valuation 12 based on willingness pay (WTP) considering farmers, a hypothetical budget 1000 € improvement trait per 1 genetic SD, linear mixed model applications. Significant differences WTP (P < 0.01) were only identified feed utilisation 2 (least-squares mean = 101.65 €) 9.46 €). Least-squares means individual summed up into four overall categories. highest importance expressed "functional", but displaying variation among cluster. All rated category "health welfare" tail length very similar (range from 24 % 29 %), even stronger emphasize over "performance" in 3. In consequence, we suggest modify goals shift towards health, welfare functionality, by consideration system particularities.

Association Between InDel and CNV Variation in the FBLN1 Gene and Slaughter Traits in Cattle

Agriculture, Journal Year: 2025, Volume and Issue: 15(5), P. 518 - 518

The FBLN1 gene encodes the fibulin-1 protein, first member of ECM glycoprotein family, and is crucial for embryonic development organ tissue formation in mammals. Our previous transcriptome analysis identified suggested its potential role influencing slaughter traits by regulating function. This study aims to uncover key genetic variants (InDel CNV) within examine relationship with beef cattle. In this study, cattle resources population Gaoqing black were selected (n = 641), leading identification three polymorphic InDel loci (13 bp insertion, 28 24 insertion) two CNVs. Association revealed that polymorphisms significantly correlated certain (p < 0.05), such as left limb weight right weight. addition, CNV skirt steak round small intestine reached extremely significant levels 0.01) chunky II high rib. summary, represent molecular markers associated These findings provide valuable insights marker-assisted selection enhance improvement breeding.
