[Laying hens in alternative housing systems--practical experiences].

Alternative keeping systems of laying hens in Germany at present are run as deep litter-, aviary- and free-range systems. After a short description of these housing types special requirements on management are considered. First solutions for the reduction of parasite and environmental burden in front of the hen-house are presented as well as opportunities to improve the utilization of that part of the outside run, which lay far from the pen. Although the management has improved a lot, the average mortality in alternative keeping systems of laying hens is still very high, probable reasons were discussed. Beside that the further development of furnished cages for groups of laying hens up to 40 and 60 individuals per unit is described; the first experiences from scientifically attended pilot projects are reported.

[Domestic animal welfare--practice oriented solutions].

Examples for practical solutions of animal welfare questions in poultry and pig holdings are described: A new inspection trolley for laying hens in battery cages with 8 floors, rearing conditions for laying hens in alternative housing systems including outdoor areas, improvement of hen-runs with plantation and mobile shelters, incidence of day-light in broiler houses, use of an automatic broiler catching machine, straw-racks and structured pens for fattening turkeys, outdoor husbandry of "Kelleyturkeys", kennelled system with "bungalows" for weaners (Nürtinger System), "Straw-Flow" systems with a sloping floor and straw provided from a freely accessible dispenser, outdoor areas with solid surface for fattening pigs, straw-racks, animal friendly construction of farrowing pens as well as an outdoor system for breeding sows.

[Animal Welfare Service of Lower Saxony--first report of experiences].

The Animal Welfare Service of Lower Saxony-part of the state veterinary services within the regional government of Weser-Ems-started its work in February 1995 at Oldenburg. The experiences during the first 18 months of activity are discussed. The main duties of the Service consist of: Advising the local district veterinary authorities concerning "problem" holdings including common control visits on occasion. Advising the offices of the court on matters concerning animal protection. Advising government offices and legislative bodies on the development and improvement of animal welfare legislation. Working on special problems of animal welfare. In particular the Service aided by various working groups is currently establishing welfare recommendations for the special fields of turkey fattening and all year grazing of cattle and sheep.

Intrapartum hepatitis B screening.

OBJECTIVE: The purpose of this study was to determine the prevalence of acute hepatitis B in intrapartum patients and to describe the birth-to-administration interval of the hepatitis B vaccine and immune globulin in hepatitis B surface antigen-positive patients detected by intrapartum screening. STUDY DESIGN: Hepatitis B screening was performed on 8712 laboring patients admitted to Forsyth Memorial Hospital in Winston-Salem, North Carolina, between July 1, 1992, and Jan. 31, 1994. RESULTS: Fourteen laboring patients had positive results for hepatitis B surface antigen (prevalence 0.16%), and two of the 14 had a profile consistent with acute disease. The average interval from birth to administration of the hepatitis B immune globulin and hepatitis B virus vaccine was 18.6 hours (range 3.9 to 31.0 hours) for hepatitis B virus-infected patients whose hepatitis B surface antigen status was unknown before labor. CONCLUSION: Intrapartum screening allows for diagnosis of the asymptomatic patient with acute hepatitis B virus infection whose hepatitis B surface antigen status was unknown before labor who would not have received hepatitis B immune globulin had only early prenatal screening been performed.

[Animal welfare aspects of broiler husbandry--studies of fattening cockerel husbandry in the administrative district of Weser-Ems].

In January 1993 a working team "animal protection in poultry fattening" at the district council of Weser-Ems presented a report of important aspects of animal welfare in broiler fattening in the district of Weser-Ems. The following main points were discussed: lighting, stable-climate, litter, feed and water, diseases and stocking density. A list of claims for animal welfare in broiler production is given.

[The occurrence and characterization of Campylobacter spp. in silver gulls (Larus argentatus), three-toed gulls (Rissa tridactyla) and house sparrows (Passer domesticus)].

Altogether 16 Campylobacter (C.) isolates could be recovered from 65 Herring gulls: 5 x C. laridis, 2 x C. jejuni biovar 1, 4 x C. jejuni biovar 2 and 5 x C. coli. Campylobacter spp. were isolated from 15 out of 51 samples from Kittiwakes: 2 x C. jejuni biovar 1 and 13 x C. laridis. All C. coli isolates grew on agar containing 1.5% NaCl. Two Campylobacter isolates from 50 House sparrows differed from all other isolates by a distinct beta-hemolysis and other phenotypic characteristics and could not be associated with a certain Campylobacter species. Epidemiological aspects and the possible role of the examined birds as a source of infection for man and domestic animals are discussed.

[The "diseased" or "dead" guillemots (Uria aalge), three-toed gulls (Rissa tridactyla), silver gulls (Larus argentatus) and laughing gulls (Larus ridibundus) found in the area of the German Bay, 1982-1985].

Between 1982 and 1985 the cadavers of 50 Guillemots (Uria aalge), 41 Kittiwakes (Rissa tridactyla), 26 Herring Gulls (Larus argentatus) and 34 Black-headed Gulls (Larus ridibundus) were examined pathological, bacteriological and virological. The probable cause of death was established. Parasitosis were particularly prevalent in Herring Gulls (49%), where the main infection--as in Black-headed Gulls--was with Cestoides. In Kittiwakes and Guillemots mainly Spiruroideae were recorded. The commonest bacterium isolated in organs and intestinal tract was Escherichia coli, followed by Aeromonas hydrophila and Clostridium perfringens. Salmonella were found in the organs of 5% and in the intestinal tract of 3% of the birds. The species of Salmonella most frequently isolated was Salmonella typhimurium varieties copenhagen. Also recorded were Yersinia intermedia Serovar 0:17 (1x), Pseudomonas spp. (2x), bacteria of the Haemophilus-Pasteurella-Actinobacillus group (1x), Pasteurella multocida (2x), Moraxella septicaemiae (1x), Campylobacter spec. (1x), Mycoplasma spec. (6x), DNase positive Staphylococcus spec. (4x) and Streptococcus spec. (6x). Less in evidence among the birds examined were fungus diseases with Aspergillus spec. (4x) and Blastomyces spec. (4x). As for viruses one Guillemot was found to have an Adenovirus and another one to have a Paramyxovirus. From one of the Herring Gulls there also was isolated a Paramyxovirus, from a second one to a Reovirus. Three other species isolated have get to be identified. The chief cause of sickness and death in the Guillemots was oil-contamination. The majority of the examined Kittiwakes and Herring Gulls were victims of pathogenic agents. Many of the Black-headed Gulls died through traumata as gunshots or road traffic etc. In order to establish the causes of sickness and death in seabirds and to ascertain the importance of the various species as possible carriers of infectious diseases, a systematic series of investigation will be necessary. Without this it will not be possible to assess their epidemiological relevance for other wild birds, domestic poultry and humans.
