Phenotypic and genetic diversity of domestic yak (<i>Bos grunniens</i>) in high‐altitude rangelands of Gilgit‐Baltistan, Pakistan Open
Due to climate change, irrigated agriculture may become restricted in the mountain valleys in northern Pakistan in the future. Hence, the importance of yak ( Bos grunniens ) keeping in the mountain ranges as risk‐mitigating strategy for mo…

Unraveling Admixture, Inbreeding, and Recent Selection Signatures in West African Indigenous Cattle Populations in Benin Open
The Dwarf Lagune and the Savannah Somba cattle in Benin are typical representatives of the endangered West African indigenous Shorthorn taurine. The Lagune was previously exported to African and European countries and bred as Dahomey cattl…

Genomic loci and genetic parameters for uterine diseases in first-parity Holstein cows and associations with milk production and fertility Open
Based on the clinical stage (e.g., vaginal discharge) and bacterial species, several forms of uterine diseases (UD) exist and can be classified as different traits [i.e., different stages of endometritis (EM) and metritis (MET)], which may…

A variance component estimation approach to infer associations between Mendelian polledness and quantitative production and female fertility traits in German Simmental cattle Open
Background Managing beneficial Mendelian characteristics in dairy cattle breeding programs implies that the correlated genetic effects are considered to avoid possible adverse effects in selection processes. The Mendelian trait polledness …

Genetic and nongenetic profiling of milk β-hydroxybutyrate and acetone and their associations with ketosis in Holstein cows Open
Ketosis is a metabolic disorder of increasing importance in high-yielding dairy cows, but accurate population-wide binary health trait recording is difficult to implement. Against this background, proper Gaussian indicator traits, which ca…

Associations between maternal milk protein genotypes with preweaning calf growth traits in beef cattle Open
The objectives of this study were to investigate milk casein polymorphisms in dams and to determine the impacts of maternal casein genotypes on growth traits of their sucking calves. Milk samples from 433 dams of the breeds German Angus (G…

The role of agro‐ecological factors and transboundary transhumance in shaping the genetic diversity in four indigenous cattle populations of Benin Open
The indigenous cattle population of Benin is a diverse mix of taurine and hybrid breeds shaped by diverse ecological and climatic conditions with eight agro‐ecological zones (AEZ). Presumably, the taurine breeds face current endangerment d…

Assessing selection signatures within and between selected lines of dual‐purpose black and white and German Holstein cattle Open
Summary The aim of this study was to detect selection signatures considering cows from the German Holstein (GH) and the local dual‐purpose black and white (DSN) population, as well as from generated sub‐populations. The 4654 GH and 261 DSN…

Are scurs in heterozygous polled (Pp) cattle a complex quantitative trait? Open
Background Breeding genetically hornless, i.e. polled, cattle provides an animal welfare-friendly and non-invasive alternative to the dehorning of calves. However, the molecular regulation of the development of horns in cattle is still poo…

Phenotypic relationships, genetic parameters, genome-wide associations, and identification of potential candidate genes for ketosis and fat-to-protein ratio in German Holstein cows Open
Energy demand for milk production in early lactation exceeds energy intake, especially in high-yielding Holstein cows. Energy deficiency causes increasing susceptibility to metabolic disorders. In addition to several blood parameters, the …
