Strömedlets betydelse för hälsa och välfärd hos mjölkkor i liggbåssystem : en litteraturstudie

University essay from SLU/Dept. of Animal Environment and Health

Abstract: This review highlights the importance of the bedding material for dairy cows in cubicle systems. The aim was to examine how different types of bedding materials affects dairy cow health and welfare in cubicle systems. To answer the questions studies have been gathered in a summary. Dairy cows can suffer from production diseases, such as lameness or mastitis. These diseases are consequences of high milk yields and environmental factors. The choice of housing system, and particularly lying surface and bedding material, is important for the comfort, health and welfare of the cow. In cubicle systems, a combination of a thick mattress and plenty of bedding material create optimal conditions. The cow can adapt to the lying surface and/or bedding materials that are offered but longer resting periods and fewer hock lesions are seen if the cubicles are provided with large amounts of bedding material. Even more important is that the bedding is dry; cows do not want to lie down on wet bedding, which contributes to increased stress for the animals. There are various types of bedding material used in cubicle systems. In Sweden these are straw (usually cut or shredded), sawdust, wood shavings, sand and peat. In recent years recycled dried manure has appeared as an alternative bedding material in Europe. Bedding has several functions. However, bedding materials may also have disadvantages. Some may increase the risk of mastitis, either by containing microbes or stimulating bacterial growth. Mastitis disrupts production and reduces welfare. In order to maximise the cow's welfare, materials that increase the risk of disease and injury should, if possible, not be used. The conclusion based on this review is that different types of bedding materials clearly have pros and cons regarding cowcomfort and health. The choice of bedding material, quantity and quality are important to cow's welfare. Additionally, management routines and lying-place hygiene contribute to cow health which is highlighted in several studies.
