New Approaches for the Quantification of Metabolic and Economic Trade-Offs Related to the Health and Longevity of Individual Dairy Cows
(2024)
Background: In dairy cows, negative associations between the genetic merit for milk yield and fitness traits as well as a lack of success in lowering the prevalence of production diseases have been noticed over the past 30 years across different production methods, herd sizes and countries. On the other hand, individual farms and individual cows within a farm succeed in simultaneously achieving high performance, low prevalence and high profitability, while others cannot cope with these challenges. Differences in milk ...

Assessment of the variation of marbling and intramuscular fat content of beef, and validation of possible factors to increase sensory beef quality
(2021-11)
This thesis focuses on the intramuscular fat content (IMF) or the marbling of beef as main parameters of sensory beef quality. The aim is to identify the high variability of these traits and to verify possible influences such as genetics, age, gender and feeding strategies to increase marbling.
The first part of this research focuses on the variation of quality traits within a genetically homogeneous line of an endangered German beef cattle breed “Rotes Höhenvieh” (RHV). The intramuscular fat content of beef samples ...
