The relationship of body condition score with disease occurrence was examined in 561 cows in nine herds. Cows were body condition scored on a five-point scale (1 = thin, 5 = obese) every 2 wk from drying off until 150 d in milk. Cows scored between 3- and 3+ were considered to be in average or good condition. Cows scored less than or equal to 2+ were considered to be underconditioned, whereas those scored greater than or equal to 4- were considered to be overconditioned. Relationships of health and condition score were examined using multiple logistic regression for dichotomous outcomes (e.g., diseased or healthy). Cows that developed dystocia or were culled lost more condition during the dry period than those that did not develop dystocia or were not culled. Cows overconditioned at drying off were more likely to develop cystic ovarian disease and reproductive problems. Cows underconditioned or overconditioned at drying off were more prone to foot problems after calving. Cows overconditioned at 30 d postpartum were more likely to have metritis.

Cows are often temporarily deprived of the opportunity to lie down while waiting for veterinary or reproductive procedures. Sixty cows were deprived of the opportunity to lie down for 0, 2, or 4 h by confining them in pairs in a small indoor pen. Behavior was recorded during deprivation and for 40 h afterwards. In the first 2 and 4 h of the experiment, cows that were not deprived chose to lie down for 70 and 142 min, respectively. When cows were discouraged from lying, they regularly stomped their legs, repositioned themselves, but never lay down. In the 4-h treatment, both stomping and repositioning increased after the first hour. Butting and weight shifting (displacing weight from one side of the body to the other) increased during deprivation, indicating restlessness. Cows deprived for 4 h sniffed and rubbed their heads against the housing more than cows deprived for 0 or 2 h. Time spent feeding and standing without ruminating increased with the duration of deprivation, especially during the early stages; standing ruminating also increased in the final stages. After deprivation, feeding time decreased, which compensated for the increase during deprivation. By 40 h after deprivation, the lying-deprived cows had recovered approximately 40% of their lost lying time. Milk yield was not affected by lying deprivation. It is concluded that cows experience discomfort during short periods of lying deprivation, after which they recover some, but not all, of the lost lying time by rescheduling feeding and standing time.

Most farm assurance schemes in the UK at least, in part, aim to provide assurances to consumers and retailers of compliance with welfare standards. Inclusion of welfare outcome assessments into the relevant inspection procedures provides a mechanism to improve animal welfare within assurance schemes. In this study, taking laying hens as an example, we describe a process for dealing with the practical difficulties in achieving this in two UK schemes; Freedom Food and Soil Association. The key challenges arise from selecting the most appropriate measures, defining sampling strategies that are feasible and robust, ensuring assessors can deliver a consistent evaluation and establishing a mechanism to achieve positive change. After a consultation exercise and pilot study, five measures (feather cover, cleanliness, aggressive behaviour, management of sick or injured birds, and beak trimming) were included within the inspection procedures of the schemes. The chosen sampling strategy of assessing 50 birds without handling provided reasonable certainty at a scheme level but less certainty at an individual farm level. Despite the inherent limitations within a time and cost sensitive certification assessment, the approach adopted does provide a foundation for welfare improvement by being able to highlight areas of concern requiring attention, enabling schemes to promote the use of outcome scoring as a management tool, promoting the dissemination of relevant technical information in a timely manner and increasing the scrutiny of standards important for the welfare of the birds.
