Since maize silage is an important forage in cattle nutrition, it is important to know its nutritive value. Much effort is put into breeding maize, and several new varieties are introduced on the market every year. This requires periodical analyses of the nutritive value of current maize varieties for the formulation of cattle rations. The aim of this study was to examine the nutritive value of whole crop maize silage (WCMS) from nine maize varieties in 3 consecutive years. For the analysis of nutrient composition and ruminal degradability of organic matter (OM), crude protein (CP), neutral detergent fibre (aNDFom) and non-fibre carbohydrates (NFC), varieties were harvested at three harvest dates (50%, 55% and 60% dry matter content in ear)...

Carnitine has long been known to play a critical role for energy metabolism. Due to this, a large number of studies have been carried out to investigate the potential of supplemental carnitine in improving performance of livestock animals including ruminants, with however largely inconsistent results. An important issue that has to be considered when using carnitine as a feed additive is that the efficacy of supplemental carnitine is probably dependent on the animal's carnitine status, which is affected by endogenous carnitine synthesis, carnitine uptake from the gastrointestinal tract and carnitine excretion...

The objective of the present study was to demonstrate the efficiency of the decontamination process applied to deoxynivalenol (DON)-contaminated maize by sodium sulphite (Na2 SO3 ) treatment in vivo. Additionally, in vitro characterisation of the toxicity of the DON sulphonates (DONS 1, 2 and 3 denote structurally different forms), the resulting DON metabolites, on peripheral blood mononuclear cells (PBMC) should substantiate the inactivation of DON. In a piglet experiment, both DON-contaminated maize and -uncontaminated control maize either untreated (DON-, CON-) or Na2 SO3 -treated (DON+, CON+) were mixed into feed and fed for 42 d starting from weaning...
