Characterization of insulin sensitivity and inflammation related factors in dairy cows receiving conjugated linoleic acids (CLA) or a control fat supplement during lactation
(2013-08-20)
With the onset of lactation, dairy cows have to mobilize body reserves, mainly body fat, to cover the output of energy via milk. The homeorhetic metabolic adaptation to the needs of milk production is accomplished through ...
Molecular genetic analysis of bovine oocytes with different developmental potentials
(2009-06-04)
Poor oocyte developmental potential contributes to reduced fertility in livestock species and hampers the application of biotechnology techniques in cattle industry that could be used for spreading certain genotypes with ...
Candidate gene analysis for loci affecting sperm quality and fertility of boar
(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 ...
Molecular genetic analysis of positional candidate genes for mammary gland characteristics in pigs
(2005)
Inverted teat reduce the number of functional mammary complexes in affected sows leading for reduction of piglet productivity and litter growth during the lactation period. This detect occures in commercial pig breeds with ...
Die Wirkung der Mikrogravitation auf das Abwehrsystemvon Schwertträgerfischen (Xiphophorus helleri, Heckel)in einem geschlossenen, aquatischen Ökosystem: immunologische und hämatologische Untersuchungen
(2006)
Background: The effect of space flight conditions on the immune system of humans and rodents was investigated since the beginning of space flight. Until now there were no investigations of the influence of microgravity ...
Expression analysis of homeobox gene family in bovine pre- and post-implantative developmental stages
(2006)
Homeobox (hox) genes encode transcription factors which regulate the expression of several target genes encoding essential proteins for cell differentiation and proliferation. Thus, hox-genes have long been recognized as ...
Detection and characterization of QTL in a porcinen Duroc-Pietrain resource population
(2005)
In the present thesis, genome scans were performed for QTL detection in a F2 resource population which was reciprocally crossed between Duroc and Pietrain. 1085 F2 progeny within 38 full-sib families were produced from ...
MicroRNAs in the bovine ovary and placentas derived from in vivo, in vitro and nuclear transfer pregnancies
(2010-12-15)
MicroRNAs are the major class of gene regulating molecules playing pivotal roles at post-transcriptional level. Identification and expression profiling are the initial steps to understand their regulation of biological ...
Epigenetic regulation of CD14 in TRIF pathway in pulmonary alveolar macrophages of German Landrace pigs
(2016-05-24)
Diseases of the respiratory system are a main problem in pig production. Pulmonary alveolar macrophages (PAMs) are key players to defend these respiratory diseases like lung inflammation caused by bacterial infection. ...
Zur tierökologischen Bedeutung der Elsbeere (Sorbus torminalis L. CRANTZ)
(2018-06-14)
Mit der vorliegenden Dissertation soll das ökologische Beziehungsgeflecht der Elsbeere (Sorbus torminalis) erfasst werden, einer in Deutschland seltenen, in zerstreuten, kleinen Populationen vorkommenden Baumart (Fam. ......
The Significance of the Wild Service Tree (Sorbus torminalis L. Crantz) in Regard to Animal Ecology
This thesis aims to document the ecological web of the wild service tree (Sorbus torminalis) – a ......
