The effects of bedding straw contaminated on average with 1.4 mg/kg deoxynivalenol (DON) and 0.9 mg/kg zearalenone on the fertility of group housed sows with daily access to pasture was tested using 48 sows kept on contaminated and 48 control sows kept on uncontaminated straw from mating until farrowing. No abortions were observed during the trial. The contaminated straw neither influenced the non return rate nor the number and birth weight of the piglets. The effects of Fusarium toxin contaminated bedding straw on fertility thus seem to be negligible in sows having access to roughage such as pasture grass.
Stable climate has an important impact on the respiratory health of horses. In a study on indoor climate quality, three different ventilation systems were tested.
Although milk-production oriented (MPO) cow breeds have also become established in the mountain region, farms with the dual-purpose ‘Original Simmental’ breed are proving to be economically viable, with lower costs and higher direct payments making up for lower revenues from milk.
High milk yields before drying-off increase the risk of udder infections during the dry period. An online survey highlights what drying-off methods are currently used and how farmers rate the ‘incomplete milking’ approach for reducing milk yield.
