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 ... -
Effects of folic acid and pantothenic acid supplementation to two rations on rumen fermentation, duodenal nutrient flow and serum and milk variables of dairy cows
Ragaller, Veronika (2010-04-08)The aim of the present experiments was to investigate the influences of a daily supplementation of 1 g folic acid (FA), respectively pantothenic acid (PA) on ruminal fermentation, as well as on serum and milk variables. ... -
Grazing behavior of two Holstein dairy cow strains under organic farming conditions in Switzerland
Heublein, Carolin (2017-04-11)The aim of the thesis was to test if concentrate supplementation is required in an organic, pasture-based feeding system and if concentrate supplementation influences grazing behavior. The study consisted of two trials, ... -
Histomorphological and immunohistochemical characterization of different fat depots of dairy cows during early lactation
Akter, Syeda Hasina (2011-11-23)Early lactation is attended by massive fat mobilization, decreased insulin sensitivity and immunosuppression. The aim of this dissertation was to study the effects of lactation and conjugated linoleic acid (CLA) on adipocyte ... -
Influence of lactation-induced and condition-dependent mobilization of body fat on bile acid metabolism of high-yielding dairy cows
Dicks, Lena (2024-06-04)The transition from pregnancy to lactation is characterized by major metabolic, phys-iological, and hormonal changes. In early lactation, dairy cows experience a negative energy balance (NEB) as the energy required for ... -
mRNA expression of the acute phase protein haptoglobin in blood and milk somatic cells and cellular localisation within the mammary gland of dairy cows
Thielen, Maria (2006)The haptoglobin (Hp) concentration in blood and milk is increasingly discussed as a diagnostic marker for bovine mastitis. This acute phase protein is mainly synthesised in the liver, however, Hp mRNA was also discovered ... -
Regulation of branched-chain amino acid metabolism in major metabolic tissues of dairy cows during late pregnancy and early lactation
Webb, Laura Ashley (2020-04-01)For dairy cows, the transition from late pregnancy to early lactation is characterized by dramatic changes in endocrine status, nutrient utilization as well as tissue metabolism. Specific metabolic processes, e.g., in ... -
Supplementation of a rumen-protected conjugated linoleic acid mixture (cis-9, trans-11; trans-10, cis-12) to early lactation dairy cows: effects on feed intake and performance
Metzger-Petersen, Katrin (2013-06-07)Conjugated linoleic acids (CLA) are geometric and positional isomers of linoleic acid with conjugated double bonds. <em>Cis</em>-9, <em>trans</em>-11 and <em>trans</em>-10, <em>cis</em>-12 CLA are the two most intensively ...
