On request of the European Commission, the AHAW Panel considered, in its first opinions in the area of dairy cow welfare whether current farming and husbandry systems meet the welfare needs of dairy cows. The Panel also evaluated the impact of genetic selection aimed at increasing milk yield on dairy cow welfare in the various farming systems used[1] , and highlighted the correlation between genetic selection and the incidence of lameness, mastitis, reproductive and metabolic disorders.

Over the last thirty years genetic selection for higher milk yield has changed the body shape and increased the size of dairy cows, therefore increasing their requirement for space. Scientific experts highlighted the importance of allocating enough space for cattle movement when designing resting, feeding and walking areas. The Panel recommended that the genetic selection of dairy cows should address their resistance to diseases such as lameness and mastitis, as well as improve their fertility, health and longevity.

Scientific experts took into account all available data in defining levels for light, indoor temperature and relative humidity for good welfare. They recommended that the design of resting, walking and feeding areas in the buildings should allow for sufficient movement and exercise. The Panel also said that while the use of tie-stalls continues, cows should have daily exercise that involves walking freely. On this point, six members of the AHAW Panel expressed a minority opinion highlighting evidence of poor welfare in dairy cattle held in tie-stalls and recommended that dairy cattle should not be routinely kept in tie-stalls

The Panel concluded that achieving reduction of mastitis can be obtained not only from treating the disease and preventing its transmission, but also from improving the animals’ immune systems. This can be achieved by minimising stress factors and through controlled and nutritionally-balanced feeding (e.g. by providing the most appropriate type of dietary fibre for the digestive system of dairy cows).

The Panel also concluded that farms with a high prevalence of lameness in dairy cows (e.g. above 10%) do not have an adequate prevention programme and should improve housing conditions, genetic selection and management practices. Moreover, farmers who are well trained in recognising signs of disease at an early stage and in knowing when to seek veterinary advice can contribute to reducing the prevalence of lameness.

Note to editors:

The Scientific Report of the AHAW Panel, which brings together all available data on the effects of farming systems on dairy cow welfare and disease, has also been published. Due to the wealth of data, the experts subdivided risk assessment in four areas: i) metabolic and reproductive disorders, ii) udder disorders, iii) leg and locomotion problems and iv) behavioural disorders, fear and pain. A scientific opinion has been finalised for each area. The Panel also adopted a fifth scientific opinion which provides an overall assessment of dairy cow welfare, gathering all the most relevant conclusions and recommendations from the four opinions and the conclusions of the scientific report.
