In Switzerland +Natura Beef® + is the brand name for suckler cow calves which will be slaughtered at weaning at the age of 10 months. The goal of this investigation was to compare production efficiency of medium sized dual purpose Simmental cows and small sized and strong by muscled Angus cows. The whole herd was mated by Angus sires. The resulting 80 calves were born in winter and spring 1997/98 and 1998/99. They stayed the following summer on an alpine pasture at 2000 m above sea level and were finished with hay and modest amounts of barley in the valley during the following autumn and winter. Live weight has been measured every two weeks. Individual feed intake was recorded regularly in the valley where the cows were fed a total mixed ration containing straw, hay and grass-silage (5,0 MJ NEL). The calves were weaned and slaughtered at once as soon as they had reached a sufficient fat cover. For this reason, at slaughter the most of the calves were older than the maximum 10 months requested by Natura-Beef® -prescriptions. In the period from lactation week 2 until 10, metabolic live weight showed a highly significant effect on dry matter intake, while no significant effect of the breed was found. During week 33 until 43 Simmental cows consumed 2 kg dry matter more than Angus cows, while no effect for metabolic live weight were found. Cows in first lactation had in both periods lower food intake than cows in second or higher lactation. The Simmental x Angus calves had a higher live and net weight gain than the pure-bred Angus calves (100 and 60 g/day). Male calves and calves from cows in second or higher lactation obtained higher weight gains than female calves and calves from cows in first lactation. Simmental x Angus calves had a higher percentage of meat and valuable meat than Angus calves (difference of 0,6 % and 1,0 %). The superiority of the dual purpose cow type to the specialised beef type in this suckler cow system is mainly caused by the higher milk yield of the Simmental cows.
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.

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.
