Zweinutzungsgeflügel Organic Eprints
Ethisch vertretbare Hühnerlinien, die wirtschaftlichen Kriterien genügen, sind heutzutage stark gesucht. Besonders in der Ökolandwirtschaft wächst das Bedürfnis nach robusten Hühnern, welche nicht infolge der Hochleistungszucht Schäden im Körperbau und Verhalten erleiden. Aus diesem Grund wurde in einer Pilotphase von 1997 bis 1998 untersucht, ob Zweinutzungshühner eine Alternative darstellen. Dabei könnten wie früher die Weibchen und die Männchen sinnvoll genutzt werden. Für die Untersuchung wurden zwei Linien geprüft, die auf dem Markt als Zweinutzungsgeflügel propagiert werden.

Zweinutzungshühner als Alternative zur Tötung von Eintagsküken Organic Eprints
Schmidt, Eggert; Damme, Klaus.
The culling of day-old male layer chicks is a constant issue in the animal welfare discussion. The dual purpose chicken is an alternative. In this test cockerels from dual purpose breeds were compared to fast and slow growing chicken. An additional fattening period of at least two weeks is necessary to achieve the final weight of 2.3 kg. Due to a decline in feed conversion approximately 20% additional feed energy is necessary to produce 1 kg lean meat. The laying performance reached an acceptable number of 260 eggs per year. An insufficient egg weight is the reason for a higher amount of S-grade eggs. Again 20% additional feed energy per kg egg mass is necessary compared to specialized breeds.

Kochakorn Direksin; Montra Manakul; Terdsak Kummeng.
The aim of this study was to monitor avian influenza subtype H5N1 infection in poultry in 3 northeastern provinces of Thailand. A total of 794 sera from chickens and ducks of local farmers were serology tested. In Khon Kaen, a total of 381 samples (chicken = 344, duck = 37) were collected from August to December 2011. In Mahasarakam, 78 chicken sera were collected in August 2011. In Karasin, a total of 335 samples (chicken = 331, duck = 4) were collected from June to September 2011 and January 2012. All of the sera were antibody negative by H5 AIV Ab ELISA kit (Anigen Animal Genetics Inc., Korea) and Hemagglutination inhibition test (HI). Chickens of a farm in Takanto district of Karasin province exhibited respiratory signs in late January, 2012. Cloacal...
