The present study was designed for a comparison of live weights and injuries due to cannibalism in laying hens with intact and trimmed beaks. Research included 16 flocks on commercial farms, of which half consisted of birds with intact beaks and the other half of birds with trimmed beaks. Farms were visited regularly from the end of the rearing period (only ten of the 16 flocks were visited on the rearing farm) until the end of the laying period for scoring skin injuries and measurements of weight using a sample of 50 birds on average. During the rearing period, no significant differences in live weights and skin injuries were detected. During the laying period, significant difference in the mean weight of birds with intact beaks and trimmed beaks was only detected between 64 and 65 weeks of age. Birds with intact beaks weighed 1807.9 g, while birds with trimmed beaks weighed 1882.0 g on average.

In der Gefl\u00fcgelhaltung stellt Kannibalismus ein weit verbreitetes Problem dar und ist der Grund f\u00fcr das Schnabelk\u00fcrzen bei Legehennen. Die vorliegende Studie sollte daher das Lebendgewicht und die durch Kannibalismus verursachten Hautverletzungen zwischen Legehennen mit intaktem und gek\u00fcrztem Schnabel vergleichen. Die Studie umfasste 16 Herden aus Praxisbetrieben, wovon die eine H\u00e4lfte aus Tieren mit ungek\u00fcrzten Schn\u00e4beln und die andere H\u00e4lfte aus Tieren mit gek\u00fcrzten Schn\u00e4beln bestand. Die Betriebe wurden regelm\u00e4\u00dfig vom Ende der Aufzuchtphase (von den 16 Herden wurden 10 auch in der Aufzucht besucht) bis zum Ende der Legephase besucht um die Gewichtserfassung und die Beurteilung der Hautverletzungen an einer Stichprobe von durchschnittlich 50 Tieren durchzuf\u00fchren. W\u00e4hrend der Aufzuchtphase wurden keine signifikanten Unterschiede im Lebendgewicht und in den Hautverletzungen festgestellt. W\u00e4hrend der Legephase wurden lediglich zwischen der Lebenswoche 64 und 65 signifikante Unterschiede im Lebendgewicht der Tiere mit ungek\u00fcrzten und gek\u00fcrzten Schn\u00e4beln festgestellt. Die Tiere mit intaktem Schnabel wogen 1807,9 g, w\u00e4hrend die Tier mit gek\u00fcrztem Schnabel durchschnittlich 1882,0 g wogen. Insgesamt zeigten 83,3 % der Herden mit ungek\u00fcrztem Schnabel und 66,7 % der Herden mit gek\u00fcrztem Schnabel einen Kannibalismusausbruch. Die Herden mit intaktem Schnabel waren durchschnittlich mit 43,5 Lebenswochen betroffen, w\u00e4hrend die Herden mit gek\u00fcrztem Schnabel mit 53,3 Lebenswochen betroffen waren. Das Ausma\u00df der Verletzungen war bei den Herden mit ungek\u00fcrztem Schnabel signifikant h\u00f6her. W\u00e4hrend des Kannibalismusausbruches zeigten 34 % der Tiere mit ungek\u00fcrztem Schnabel eine Maximalverletzung von 5 mm oder mehr, verglichen mit 20, 7 % der Tiere mit gek\u00fcrztem Schnabel.<\/p>
