Effect of different storage conditions on the mycotoxin contamination of Fusarium culmorum-infected and non-infected wheat straw.

Mycotoxins are known to affect the health and performance of farm animals. In contrast to cereal grains, the straw is only rarely analysed for mycotoxins, although contaminated straw could additionally expose farm animals to mycotoxins. For this reason, two experiments were carried out to examine the effect of pre-harvest Fusarium infection (inoculation with F.

Effects of feeding a Fusarium toxin-contaminated diet to infectious bursal disease virus-infected broilers on the protein turnover of the bursa of Fabricius and spleen.

Two experiments were carried out to examine the effects of feeding an uncontaminated control diet (CON) or a Fusarium toxin-contaminated diet (FUS; 10.7 mg deoxynivalenol [DON]/kg diet) to growing broilers, which were either uninfected or infected with infectious bursal disease virus (IBDV) beginning at 1 day post hatch. Broilers had been infected at three weeks post hatch with either a classical virulent infectious bursal disease virus (IBDV-IM, Exp.

Assessment of reference values for copper and zinc in blood serum of first and second lactating dairy cows.

The influence of different copper and zinc contents in rations on blood serum concentrations in dependence on feeding (Groups A and B) and lactation (Lactation 1 and 2) was tested in a feeding trial with 60 German Holstein cows. All animals received a diet based on maize and grass silage ad libitum. 30 cows received a concentrate supplemented with copper and zinc as recommended (Group A), whereas the other 30 animals were offered a concentrate with roughly double the amount of copper and zinc (Group B).
