In a trial with 4 × 500 growing pullets of Bovans brown hybrid, the effect of access to litter material (wood shavings) from day 1 on (E1) in comparison to offering litter from day 10 on (E10) was compared up to week of age 16. Pullets were kept in an aviary system of Harmony 3A-type. Of each pen, 375 randomly chosen pullets were moved into the layer house in week of age 18, where a Voletage-aviary system with a total of four units had been installed. During the growing period, lower animal weights (E1: 1’392 g, E10: 1’452 g), better weight uniformity (E1: 73,0 %, E10: 69,5 %) and decreased feed consumption (- 3,9 %) were determined for the E1-pullets. The largest differences were seen in mortality rate in the E1-groups (E1: 11,2 %, E10: 1,6 %). They were mainly due to losses by getting crushed to death during dimming the light in the evening in weeks of age 6 and 7. During the laying phase (weeks of age 21 to 80, including a moulting period beginning in week 50), differences in laying performance, feed consumption, egg weight and egg classes were neglectable. Furthermore, lower mortality rates (E1: 3,2 %, E10: 6,5 %) due to less cannibalism losses as well as a slightly improved plumage condition resulted in the E1-groups. It was concluded, that access to litter material should be offered to chicks from day 1 on although high losses during the growing period may occur.
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.
