Abstract

1. Keel bone damage, such as deformations and fractures, is a severe problem regarding animal welfare in layers. To identify risk factors under commercial conditions, 33 layer flocks (22 barn, 11 free range) with white (n = 18), brown (n = 11) and mixed (n = 4) genotypes were examined. 2. Keel bone status was frequently scored by palpation throughout the laying period. Data on housing and management conditions were collected. Multiple regression and Generalized Estimating Equations procedure were used for analysis. 3. At 65–74 weeks of age, the prevalence of keel bone damage ranged between 26% and 74%. White genotypes and those kept in multi-tier systems developed significantly (p < 0.05) more keel bone damage than brown genotypes or those kept in single-tier systems. Wing feather condition was associated with keel bone damage (p < 0.05), while other investigated variables regarding health, housing and management were not associated. 4. In conclusion, housing and management should be adapted to meet the birds' specific needs in multi-tier systems, which may vary for brown and white genotypes. Whether those differences result from genotype associated predispositions or other individual traits remains to be determined. [ABSTRACT FROM AUTHOR]

Abstract

1. Within a triennial project, 34 layer flocks with untrimmed beaks were examined regularly throughout the laying period to broaden knowledge on the occurrence and development of severe feather pecking and cannibalism, as well as on factors influencing this non-desirable behaviour. 2. Flocks involved 850 to 27,183 hens of seven different genetics, kept in a barn or on free-range systems. Damage to the plumage and skin was assessed in individual hens during each visit and their body weights recorded. Correlations smaller than 0.8 between different body areas for damage indicated the necessity to consider them separately. Accounting for the risk of bias due to unevenly distributed factors, regression functions were used to assess associations between pecking damage, losses and performance, housing and management conditions. In addition, temporal pattern of pecking damage for flocks with severe, medium and little damage was modelled using these functions. 3. As expected, plumage damage increased with age, whereas the development of skin lesions was less consistent. From 30 weeks of age, pecking damage on the back increased remarkably in flocks with the most severe scores compared to those with medium and little damage, especially during the later laying period. Associations were found between pecking damage on the back of hens with plumage quality of pullets when entering the layer house (point of lay). Damage to the vent/cloacal region was more pronounced in white compared to brown layers. However, this did not deny the importance of factors not significant in this study. 4. The study identified factors related to genetics and status of hens when entering the layer house, particularly the influence of the rearing phase. [ABSTRACT FROM AUTHOR]

Abstract

Thrombolytic treatment of acute myocardial infarction (MI) is limited by the time elapsed since onset, accuracy of the diagnosis and the presence of contra-indications. These factors were prospectively investigated in 173 consecutive patients with proven acute MI, admitted to a city hospital between July and December 1986. Fifty-eight patients (35%) were admitted within three hours of onset of symptoms. Delay in calling a doctor or ambulance was significant: 50% of patients waited for more than two hours after onset of symptoms, 40% more than three hours. Duration of transport to hospital averaged 30 min. Infarct-typical angina of at least 30 min had been present in 143 patients (83%). Atypical symptoms and silent MI was more frequent in the older patients. Diagnostic ST segment elevation of 2 to 3 mm on admission was present in 59 (34%) patients. After consideration of contraindications, present in 120 patients with altogether 165 potential factors, thrombolytic treatment was possible in only seven (4%) of those with the greater ST elevations within three hours after onset of symptoms and 13 (7.5%) within six hours. The most frequent contraindications were age (over 75 years), hypotension, re-infarction at the same site, intramuscular injections (unspecified drugs) within the preceding seven days, or resuscitation with cardiac massage before admission.
