In Switzerland, the entry of veal calves in the fattening unit at the age of 4-7 weeks coincides with the transition from passive to active immunity. The main objective of this study was to determine the effect of the entry age in the fattening unit on the health status of veal calves. Three groups of 30 calves ranging from 2 to 4, 5 to 7 and 8 to 10 weeks of age were simultaneously brought to the fattening unit. The age of entry influenced neither clinical symptoms or respiratory disorders incidence. The number, duration, and success rate of the antibiotic treatments were similar in the three groups. In conclusion, the arrival of veal calves in the fattening unit during the period of immune transition did not have any negative influence on their health status.
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.
