Feeding strategies to improve the nutritional value of pork and at the same time reduce the environmental burden were examined on three pig farms representing single-feed, two-phase and multi-phase feeding systems. The experimental feed was supplemented with selenium, vitamin E and crushed linseed. Furthermore, the protein content was reduced. Fattening runs with common feed served as control. The experimental feed did not consistently affect daily weight gains, but feed consumption increased and feed conversion was impaired in most of the runs. Carcass composition was impaired only in the single-feed system, as evidenced by decreased loin muscle diameter and increased backfat thickness. The lean meat content of pigs in the multi-phase system (reduction in weekly stages from 155 to 125 g crude protein per kg feed) did not decrease, but intramuscular fat content increased, which may indicate a slight under-supply of protein. Overall, the reduction of protein in the feed hardly improved protein efficiency (i.e. protein retention/excretion).
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.
