Two different pasture utilisation systems – rotational versus continuous – were compared during the grazing seasons of the years 1995 – 98, each with a herd of 24 dairy cows of mixed age and stage of lactation, including dry cows. The two herds were split again into two groups each which were fed different supplements in-barn: either up to 5 kg dry matter (DM) of maize silage per animal per day or hay and grain mix to provide the same energy supply. Additional grain mix was offered at high milk production level.<br><br>Mean daily milk production results show that neither grazing system nor type of supplementation had a significant effect. Lactation curves during the grazing season were similar in either system. Milk fat and protein content were not different between treatments. A calculation of production potential per hectare of pasture used revealed better results for rotational grazing, but the yearly variation was considerable.
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.
