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
(2013-06-07)
Conjugated linoleic acids (CLA) are geometric and positional isomers of linoleic acid with conjugated double bonds. Cis-9, trans-11 and trans-10, cis-12 CLA are the two most intensively studied isomers. The cis-9, trans-11 ......

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
(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. ...
Histomorphological and immunohistochemical characterization of different fat depots of dairy cows during early lactation
(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 ...
Dietary strategies to optimize energy and glucose supply to lactating dairy cows
(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, ...
Grazing behavior of two Holstein dairy cow strains under organic farming conditions in Switzerland
(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, ...
