“…The result indicates that these different approaches appear to be ‘measuring’ a similar underlying property. The result also indicates that the welfare of housing systems can be assessed by every assessment, which also agrees with previous studies of ANI (Alban et al . 2001; Bokkers & Koene 2001; Mollenhorst et al .…”

“…The result also indicates that the welfare of housing systems can be assessed by every assessment, which also agrees with previous studies of ANI (Alban et al 2001;Bokkers & Koene 2001;Mollenhorst et al 2005) and Bracke's science-based model (Bracke et al 2002a). The correlation between ANI and animal-based measurements has been reported for both laying hens (Mollenhorst et al 2005) and other farm animals (Alban et al 2001;Bokkers & Koene 2001). Comparing our model with ANI and FOWEL in detail, LC scored better than SC and SF better than LF in our model and FOWEL, while LC had the same score as SC and SF was worse than LF in ANI (Fig.…”

To increase the validity of evaluations and facilitate expansion and maintenance of assessment systems, we constructed a database of studies on the welfare of laying hens around the world. On the basis of this database, we devised a science-based welfare assessment model. Our model includes measurements, levels and weightings based on the scientific studies in the database, and can clarify the advantages and disadvantages of housing systems for laying hens from the viewpoint of the five freedoms. We also evaluated the usefulness of our model by comparing it with environment-based Animal Needs Index (ANI), another science-based model called FOWEL, and animal-based measurements. Our model showed that freedom from injury, pain and disease, and freedom from discomfort were more secure in the cage system, while non-cage systems scored better for natural behavior and freedom from fear and distress. A significant strong-positive correlation was found between the animal-based assessment and the total scores of ANI (rs = 0.94, P < 0.05), FOWEL (rs = 0.99, P < 0.05) or our model (rs = 0.99, P < 0.05), which indicate that these different approaches to welfare assessment may be used almost interchangeably to 'measure' a common property ('overall laying hen welfare'). However, assessments using our model and FOWEL were more sensitive than ANI and can be applied to cage systems, which suggest that our model and FOWEL may have added value.

“…Welfare measures can be classified into categories that assess housing and facilities (resource-based measures), farmer policies and management strategies (management-based measures), and direct animal observations (animal-based measures) [4,5]. Animal-based measures often reflect the outcome of resource inputs and management practices, and therefore there is increasing interest to incorporate these measures in welfare assessments, as they provide an integrative and direct measurement of the welfare state of animals [6,7,8]. Some examples of animal-based measures include the assessment of the nutritional state (e.g., body condition score), environmental conditions (e.g., fleece cleanliness) and diseases (e.g., lameness).…”

Simple SummaryThe aim of this study was to assess the reliability and practicality of 10 animal-based welfare measures for extensively managed ewes, which were derived from the scientific literature, previous welfare protocols and through consultation with veterinarians and animal welfare scientists. Measures were examined on 100 Merino ewes, which were individually identified and repeatedly examined at mid-pregnancy, mid-lactation and weaning. Body condition score, fleece condition, skin lesions, tail length, dag score and lameness are proposed for on-farm use in welfare assessments of extensive sheep production systems. These six welfare measures, which address the main welfare concerns for extensively managed ewes, can be reliably and feasibly measured in the field.AbstractThe reliability and feasibility of 10 animal-based measures of ewe welfare were examined for use in extensive sheep production systems. Measures were: Body condition score (BCS), rumen fill, fleece cleanliness, fleece condition, skin lesions, tail length, dag score, foot-wall integrity, hoof overgrowth and lameness, and all were examined on 100 Merino ewes (aged 2–4 years) during mid-pregnancy, mid-lactation and weaning by a pool of nine trained observers. The measures of BCS, fleece condition, skin lesions, tail length, dag score and lameness were deemed to be reliable and feasible. All had good observer agreement, as determined by the percentage of agreement, Kendall’s coefficient of concordance (W) and Kappa (k) values. When combined, these nutritional and health measures provide a snapshot of the current welfare status of ewes, as well as evidencing previous or potential welfare issues.

“…In dairy production systems this will include not only animals producing milk, but also the newborn, young female animals that are used as replacements and males in rearing units (Von Borell et al, 1996). Human beings have long been concerned about the welfare of animals and this concern is still growing (Alban et al, 2001). Because of the fact that dairy welfare became part and parcel of milk quality, its monitoring is an additional guarantee for the consumers that the products they buy derive from healthy animals, bred and kept according to standards of good practices in farms (Dawkins et al, 2003).…”

Animal welfare means how an animal is coping with the conditions in which it lives; it is based on 'five freedoms' and 'four principles' of animal welfare. Dairy cattle are considered as sentient beings due to which husbandry should be provided as per their needs. As cattle and human beings are intrinsically connected to each other, protection of cattle from diseases and unnecessary suffering should become prime responsibility of human. Welfare of dairy cattle cannot be measured directly, as is multidimensional in nature and can be measured by various indicators which are either direct or indirect. In this review we try to analyze dairy cattle welfare, their indicators and their assessment.
