Application of knowledge discovery and data mining methods in livestock genomics for hypothesis generation and identification of biomarker candidates influencing meat quality traits in pigs
Sahadevan, Sudeep (2014-12-10)Recent advancements in genomics and genome profiling technologies have lead to an increase in the amount of data available in livestock genomics. Yet, most of the studies done in livestock genomics have been following a ... -
Association and expression study of CD9, PLCz and COX-2 as candidate genes to improve boar sperm quality and fertility traits
Kaewmala, Kanokwan (2011-04-06)The transcription factors tetraspanin CD9 (CD9), phospholipase C zeta (PLCz) and cyclooxygenase isoenzyme type 2 (COX-2) are believed to play a key role in spermatogenesis in rat, mouse and human. However, no study was ... -
Beratung von milchviehhaltenden Betrieben auf der Basis von Verhaltens- und Erscheinungsparametern ihrer Milchkühe
Dahlhoff, Katharina (2014-07-03)In Liegeboxenlaufställen für Milchkühe kann es durch eine suboptimale Gestaltung der einzelnen Funktionsbereiche und ein nicht ordnungsgemäßes Management zu Beeinträchtigungen der Tiere kommen. Um die in vielen Milchviehbetrieben ... -
Biological control of leaf pathogens of tomato plants by Bacillus subtilis (strain FZB24): antagonistic effects and induced plant resistance
Sultan, Muna (2012-09-03)Bacillus subtilis reisolated from the biological control agents FZB24® and Phytovit® has shown promising results against several pathogens causing important foliar tomato diseases (late blight, ... -
Bovine microRNomics: Implications during oocyte maturation and pathophysiology of endometrium
Hailemariam, Dagnachew Worku (2011-05-04)MicroRNAs which are known for posttranscriptional gene regulation are evidenced for their essential role during animal development and disease. In this study, identification and expression profiling of bovine miRNAs during ... -
Bovine ovarian hyperstimulation induced changes in expression profile of circulatory miRNA in follicular fluid and blood plasma
Seifi Noferesti, Sina (2014-11-14)Circulatory noncoding small RNAs (miRNAs), which are present in various body fluids, are reported to be potentially used as biomarkers for disease and pregnancy. The present study was conducted to investigate the effect ... -
Bovine pre-transfer endometrium and embryo transcriptome fingerprints as predictors of pregnancy success after embryo transfer
Salilew Wondim, Dessie (2010-10-08)Aberrant endometrial and embryonic gene expression is one of the causes of pregnancy failure in cattle. However, selecting cows with adequate endometrial receptivity and embryos of higher developmental competence based on ... -
Candidate gene analysis for loci affecting sperm quality and fertility of boar
Lin, Cailu (2005)Fertility is one of the most important economical traits in swine production. Implementation of artificial insemination (AI) in swine production allowed improving selection on the boars for production traits, but at the ... -
Comparative intake and digestibility among ruminant species fed forage-based diets
Riaz, Muhammad Qaiser (2015-02-02)The first ruminants evolved about 50 million years ago and were small forest dwelling omnivores. Today there are about 200 species of ruminants which include both wild and domestic species. Cattle, sheep, and goats account ... -
Detection and characterization of QTL in a porcinen Duroc-Pietrain resource population
