Swiss milk producers must drastically reduce their production costs. To achieve this, they need user-orientated practical recommendations and planning aids. At present the high yield strategy (HL) and the full grazing or low-cost strategy appear most promising. In the framework of the project “Opti-Milk”, each of these two strategies was consistently optimised and implemented on nine pilot farms. The farms were then studied in detail for two and a halve years. Apart from the high milk quota of the HL farms, the average structure of the pilot farm groups was well comparable with that of a group of representative farms. The initial average milk yield was ca 6000 kg for the VW-farms and ca 8000 kg for the HL farms. During the project it increased by about 900 kg for the HL farms. On the VW farms it decrease slightly due to change to seasonal calving in early spring. This publication presents general information about the project. Detailed results will be presented in a series of further publications and used to work out recommendations and planning aids

In both sport and alternative agriculture, horses are once again being used as draught animals. Efficient power transmission plays an important role in the wellbeing of draught horses.
A study by Vetsuisse shows that the outdoor veal calf concept reduces antibiotic consumption in calf fattening by 80%. AGRIDEA has examined the economic viability of outdoor veal calf production and concludes that it cannot compete with conventional veal calf fattening.
In contrast to pigs, dairy cattle are as yet rarely fed protein-reduced diets. Studies show that there is also potential for protein savings in cattle, and thus for reducing ammonia emissions.
