In the proposed project, we will explore the benefits of increasing the longevity of dairy cows under Swedish conditions by changes in herd management. We will focus on effects on methane emissions by modelling, using existing data from the Swedish Official Milk Recording Scheme and results from an advanced computer simulation tool, SimHerd, to evaluate farm profitability. Milk from cows in diffferent lactations will be analysed for processing traits.
Hypotheses: Methane emissions will decrease by increasing herd longevity since the productive life of the cow will be longer in relation to the time until productive life starts. Reduced recruitment of heifers will increase the economic profitability on the farm since heifer rearing is associated with significant costs. By increased longevity in the herd, total milk yield from the herd will increase but raw milk composition and processing properties will not be negatively affected.
I det här projektet kommer vi att undersöka fördelarna med att öka livslängden hos mjölkkor under svenska förhållanden genom förändringar i rekryteringsstrategin. Vi kommer att ha fokus på metanutsläppen genom att modellera dessa, använda data från kokontrollen och resultat från avancerade datasimuleringar i programmet SimHerd för att utvärdera lönsamheten. Mjölk från kor i olika laktationsnummer kommer att analyseras för processegenskaper.
Hypoteser: Metanutsläppen kommer att minska genom att öka livslängden hos korna eftersom tiden som korna är produktiva blir längre jämfört med tiden innan kon börjar mjölka. Minskad rekrytering av kvigor ökar lönsamheten i besättningen eftersom kviguppfödning är kostsamt. Genom att öka livslängden i besättningen kommer totala mjölkmängden att öka i besättningen, men mjölksammansättningen och processegenskaperna kommer inte att påverkas negativt.

A cornerstone of the Swedish Food Strategy is trust in Swedish food production. Yet each year Swedish farmers and food processors lose both money and trust due to food fraud, especially for non-Swedish meat relabelled as Swedish. Most fraud remains undetected.
