This paper illustrates the importance of the analytical method for the determination of fatty acid composition in feed. In Switzerland, not only the lipid content but also the fatty acids profile are necessary to formulate a ration that will produce an optimum quality of fat in the pig carcass. Results of this study showed that the fatty acid profile obtained by gas chromatography (GC) with in situ transesterification was more accurate and complete than that obtained by a GC method in two steps (fat extraction followed by esterification) or by a gravimetric empirical method which employed the extraction of soluble compounds in a given solvent.
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.
