Accumulation and decontamination kinetics of PCBs and PCDD/Fs from grass silage and soil in a transgenerational cow-calf setting

Autor: Charlotte Driesen, Sylvain Lerch, Raphael Siegenthaler, Paolo Silacci, Hans Dieter Hess, Bernd Nowack, Markus Zennegg

Publikováno v: Chemosphere. 296

Polychlorinated biphenyls (PCBs) and dibenzo-p-dioxins/dibenzofurans (PCDD/Fs) are bioaccumulative pollutants that endanger bovine food safety. Bioaccumulation depends, among others, on the physiological dynamics of the cow's reproductive cycle. Howe

Food of animal origin accounts for >90% of the overall human exposure to polychlorinated biphenyls (PCBs). Food regulatory maximum levels help to control this exposure, but bovine meat has been found to be prone to exceed those occasionally. In order

Mineral concentrations of fresh herbage from mixed grassland as influenced by botanical composition, harvest time and growth stage

Autor: Hans-Dieter Hess, Ueli Wyss, Yves Arrigo, Patrick Schlegel

Publikováno v: Animal Feed Science and Technology. 219:226-233

The mineral concentrations in herbage from mixed grassland are variable which lead to challenging situations for animal’s mineral supplementation. The aim of this study consisted in assessing macro and micro mineral concentrations in fresh herbage

In 2006, new maximum levels for the concentration of dioxins (PCDD/F) and dioxin-like PCB (dl-PCB) in food entered into force in the European Union [Regulation (EC) No 199/2006]. The Swiss Confederation decided to adopt these values from the 1 Januar

Effects of concentrate supplementation in early lactation on nutrient efficiency, ruminal fermentation and reticular pH of zero-grazing dairy cows with differing milk production potentials

Autor: Frigga Dohme-Meier, Manuela Falk, Josef Johann Gross, R. S. Zbinden, Rupert M. Bruckmaier, Hans-Dieter Hess, Andreas Münger

In Switzerland, fresh herbage is a favoured feed for dairy cows due to its high quality and availability and low production costs. However, transition and early lactation are periods characterized by an increased nutrient demand that may not be cover

Research in ruminant nutrition and helminth control with forages, which contain condensed tannins (CT), suggests that varying responses may depend not only on CT concentration but also on CT composition. An experiment was designed to test this by fee

Changes in in vitro ruminal and post-ruminal degradation of tropical tannin-rich legumes due to varying levels of polyethylene glycol

Autor: Juan E Carulla, Hans-Dieter Hess, Martha L Pabón, M. M. Knowles

Publikováno v: Journal of animal physiology and animal nutrition. 101(4)

We evaluated the effects of tannins from Flemingia macrophylla (CIAT 17403) and Calliandra calothyrsus (San Ramon CIAT 22310 and Patulul CIAT 22316) on in vitro ruminal and post-ruminal dry matter and apparent protein degradation. For each tannin sou

Ruminal dry matter and crude protein degradation kinetics of five sainfoin (Onobrychis viciifolia Scop) accessions differing in condensed tannin content and obtained from different harvests

Sainfoin is known to vary in content of condensed tannins (CT) among accessions and harvests. In the present study, the hypothesis was tested that this results in significant differences in ruminal degradation kinetics and, with that, suitability to
