Animal welfare assessment at group level is a scientific discipline that is rapidly developing. The interest in welfare assessment systems is based on an ethical concern for the welfare of farm animals. The scientific community plays an important role in delivering an appropriate repeatable, valid and feasible framework for these assessments. Consideration of the potential applications of these techniques is important for deciding upon the requirements of specific assessment systems. This paper provides a brief overview of the different types of applications, which can be categorised broadly into research, legislative requirements (non-voluntary), certification systems (voluntary) and advisory/management tools. These applications may have various goals: quantification of welfare, provision of welfare assurance or welfare management. Assessment systems vary in many characteristics, such as whether they are animal- or resource-based, and whether they are based on single or integrated scores. Different applications will require different elements of these features.

It is not sufficient to merely publish regulations and strictly control them to improve the living conditions of farm animals. The farmer must receive precise information, understand the individual measures and be able to act with personal responsibility. A new animal welfare law has been in force in Austria since the 1st of January 2005. A system of self-evaluation is being developed for putting these new legal requirements into practice. The aim of this self-evaluation system is to enable every farmer to personally check his animal housing system against the given standards. This independent work motivates the farmer and makes him aware of animal welfare issues. This new strategy for the implementation of animal welfare law was originally developed, tested and found to be successful by the Federal Administration of the Austrian Province of Vorarlberg. Self-evaluation is to be carried out by means of specific checklists and manuals. Checklists and manuals are currently being drawn up for cattle, pigs, poultry, sheep and goats. The checklists and manuals will include all of the requirements of Austrian animal welfare legislation and will be formulated in easily understandable questions with ‘yes’ or ‘no’ answers. The manuals will describe the methods for assessing legal requirements on the farm as well as the conditions for compliance with legislation, and give advice on how to improve the state of animal welfare on the farm. This paper gives an example of the self-evaluation system for cattle farming.

Suitable systems for the assessment of animal welfare are in increasing demand. In Austria, the TGI 35 L Animal Needs Index is widely used and has been shown to be a feasible and reliable tool for animal welfare assessment on farms. Here we focus on the validity of TGI 35 L assessments, and explore the correlation between animal welfare as assessed by the TGI 35 L and animal health and behavioural parameters. From the results, it can be determined whether the criteria assessed by the TGI 35 L are preconditions for a high level of health and normal behaviour. Behaviour and health were examined in 11 cattle houses, totalling 169 animals. Behaviour was observed for two days on each farm. Data on resting behaviour, comfort behaviour, social behaviour, feed intake behaviour and eliminative behaviour were collected. Health was assessed using veterinary examinations carried out according to the General Clinical and the Orthopaedic Examination Proceedings. Significant correlations were found between the TGI scores and behaviour and health, including results for skin lesions and injuries. This indicates good validity of the TGI 35 L assessment system for cattle. A comprehensive system for the assessment of animal welfare on farms must comprise parameters of housing, climate, management and stockmanship, and animal-related parameters.
