Acute impact of dietary pattern and walking on postprandial metabolism, attention, and mood in older adults with a cardiovascular disease risk phenotype
Diekmann, Christina (2020-01-27)Attenuating the postprandial stress response and its associated inflammatory and endothelial events through specific nutritional and lifestyle interventions seems to be a promising and important approach to decrease the ... -
Adiponectin in Cattle: Profiling of molecular weight patterns in different body fluids at different physiological states and assessment of adiponectin’s effects on lymphocytes
Heinz, Johanna Franziska Lisa (2014-07-07)Adiponectin (AdipoQ), one of the most abundant adipokines found in circulation exerts various meta-bolic functions, e.g. improving insulin sensitivity and ameliorating tissue inflammation. It is secreted in different ... -
Analyses of immune competence traits and their association with candidate genes in pigs
Phatsara, Chirawath (2007)The present study was carried out to investigate the immune competences of a backcross DUMI population. Complement activity via classical and alternative pathways were determined using haemolytic activity assay. Antibodies ... -
Ansätze zur Untersuchung der genetischen Ursachen für den Erbfehler Stülpzitze beim Schwein
Jonas, Elisabeth (2007)Der Gesäugekomplex ist bei Säugetieren für die Versorgung der Nachkommen mit Nährstoffen und für die Immunisierung über die Kolostralmilch von Bedeutung. Die ersten Anlagen der Zitzen sind in der fötalen Entwicklung früh ... -
Cellular energy supply and aging in dairy cows: Characterization of different physiological states and impact of diet-induced over-condition
Laubenthal, Lilian (2015-09-24)Lactation in dairy cows is accompanied by dramatic changes in energy balance and thus requires the continued adaption of the key organs, namely adipose tissue (AT), liver, and mammary gland to the varying conditions. The ... -
Challenges related to statistical methods and sensor systems for the daily prediction of health disorders in individual dairy cows
Post, Christian (2023-02-02)The use of digital support systems has become a standard in dairy farming, and significant effort has been made to detect individual animals that are in need for a treatment by using sensor data. However, developing systems ... -
Changes of inner teat morphology caused by the milking process and by incomplete milking during dry-off as assessed by innovative technologies
Martin, Lisett Marie (2020-03-03)In dairy farming, the timing of the lactation cycle and the way of milk removal differ considerably from the natural conditions. Ensuring good health and wellbeing of farm animals is of great interest from both an economic ... -
Characterization of adiponectin at different physiological states in cattle based on an in-house developed immunological assay for bovine adiponectin
Singh, Shiva Pratap (2014-02-07)Adipose tissue (AT), through secretion of adipokines, plays a central role in regulating metabolism. Adiponectin is one of the most abundant adipokines and is linked with several physiological mechanisms such as insulin ... -
Characterization of insulin sensitivity and inflammation related factors in dairy cows receiving conjugated linoleic acids (CLA) or a control fat supplement during lactation
Saremi, Behnam (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 ... -
Characterization of porcine milk exosomes from different stages of lactation
Furioso Ferreira, Rafaela (2023-05-11)Exosomes are membranous vesicles considered major players in cell-cell communication. Milk provides adequate nutrition, transfers immunity, and promotes neonate development, and milk exosomes are suggested to have a key ... -
Chlamydieninfektionen bei Milchkühen in Nordrhein-Westfalen, Prävalenz, Risikofaktoren, Kennziffern und Vorhersagewahrscheinlichkeiten
Kemmerling, Kirsten (2010-01-04)Primäres Ziel dieser Arbeit war es, die Prävalenz von Chlamydophila spp. in zufällig ausgesuchten Milchviehbetrieben in Nordrhein-Westfalen mit Hilfe einer hoch sensitiven genus-spezifischen real-time PCR festzustellen. ... -
Detection and characterization of QTL in a porcinen Duroc-Pietrain resource population
Liu, Guisheng (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 ... -
Developmental competence of equine oocytes after ICSI: Implications on technical, morphological and cellular aspects
Mohammadi-Sangcheshmeh, Abdollah (2010-03-30)Using equine intracytoplasmic sperm injection (ICSI) procedure, the present study was performed, (i) to study the effect of assisted oocyte activation with calcium ionophore A23187 on developmental competence of oocytes, ... -
Dietary strategies to optimize energy and glucose supply to lactating dairy cows
Benninghoff, Jens (2015-11-24)Ruminants usually absorb only small quantities of glucose directly from the small intestine, because the majority of the glucose, regardless of dietary source, is fermented in the rumen to short chain fatty acids. Thus, ... -
Effect of an inflammatory stimulus on mitochondrial functionality in liver cells of dairy cows
Alaedin, MohamadTaher (2021-05-26)Mitochondria are essential organelles with key roles in metabolism and health; their function is influenced by various exogenous and endogenous factors. Dairy cows undergo a negative energy balance (EB) and a systemic ... -
Effect of niacin on the efficiency of nitrogen utilisation in the rumen of dairy cows
Aschemann, Martina (2012-08-14)The aim of the present study was to investigate the effect of an oral niacin supplementation of 6 g per day to a diet deficient in ruminally degradable protein (RDP) on rumen metabolism, microbial protein synthesis, nitrogen ... -
Effect of thyme, oregano and their major active components on performance and intestinal microbial populations of broilers
Abdel-Wareth, Ahmed Aboubaker Abdel-Moniem (2011-05-20)The aim of the present study implied an evaluation of the potential of different increasing levels of thymol, carvacrol, a mixture of thymol and carvacrol, as well as thyme and oregano as feed additives in broiler diets, ... -
Effects of different feeding regimes applied during rearing of dairy calves: circulating adiponectin and insulin sensitivity in early life and around the first lactation
