This compilation of three tests was aimed at measuring the effect on meat quality of differences in growth rate between a period of reduced feeding level during summering on mountain pastures and a period of finishing. A total of 117 Limousin (LI) X Red Holstein(FT) crossbred steers were used for this synthesis comprising various modes and levels of feeding during the finishing period. The animals were divided into four classes based on the average daily growth rate (DGR) between the two experimental periods, 0 – 500 g, 501 – 1000 g, 1001 – 1500 g and 1501 – 2000 g. On average, at slaughter, the carcass weight, the conformation, and the fatteness score were similar. The tissue composition of sirloin was similar. In the longissimus dorsi muscle, the distribution but not the size of the different types of muscle fibres was modified. The greater the difference in DGR, the more fibres were of the rapid contraction and glycolytic type (IIX), the more losses of exudates and the lower the final pH. On the other hand, there seemed to be a positive correlation with tenderness measured by sensory analysis as well as measured by shear force whereas the sarcomere length and myofibrillar fragmentation index remained unchanged.
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.
