| Bundesweit 40 Betriebe wurden mit dem Ziel erhoben, die Lahmheitssituation in der ökologischen Zuchtsauenhaltung in Stallhaltungsverfahren mit Auslauf zu erfassen. Die mittlere Lahmheitsprävalenz der tragenden Sauen lag bei 6,9 % (0 – 34,8 %, Median 5,1 %) und somit auf deutlich niedrigerem Niveau als Literaturangaben für die konventionelle Zuchtsauenhaltung. Auf einzelnen Betrieben können Lahmheiten jedoch in erheblichem Umfang auftreten; ihrer Vermeidung sollte aus Tierschutz- und ökonomischen Gründen in jedem Fall Beachtung geschenkt werden. Risikofaktoranalysen mittels multivariater logistischer Regression ergaben folgende Einflussfaktoren: In Betrieben, für die die Wurfzahl der Sauen bekannt war (n=28 Betriebe, 447 Sauen), stieg mit steigender... |

| Group housing of calves is an animal-friendly natural and economic way of raising calves. One major disadvantage of artificial milk feeding in group housing systems, however, is the incidence of cross-sucking. The main objective of this study was the evaluation of tructural and technical modifications of the feeding stall of an automatic teat feeder and the environmentally enriched feeding area in relation to a reduction of cross-sucking after finishing a milk meal. The experiment was carried out with 168 female calves (German Holstein) of one origin randomly assigned to two treatments: control group and optimized group with a furnished post feeding area and an exercise yard with environmental enrichment. Calves were fed by an automatic teat feeder... |

| ZCastrated heavy pigs of > 160 kg body weight are used for traditional pork specialties (e. g. air-dried sausages) due to the required fat quantity and quality. Today most organic production systems use modern hybrids (Hy) with often insufficient fat features. The use of endangered breeds with high body fat synthesis capacity, e. g. German Saddleback (Sa), could be an alternative with a positive effect on maintaining biodiversity. This study with a total of 132 castrates analysed the effects of 3 different genotypes (Sa, Piétrain*Sa, Hy) and 2 different roughage sources (grass-clover-silage, straw) on performance, carcass-, meat-, fat-, and product-quality. The present paper deals with performance (PF) and carcass quality (CQ). It was found that PF and... |

| The aim of the study was assessing lameness prevalence in organic sows as well as identifying potential risk factors for lameness. The project focused on sows in organic farms with access to an outdoor run. Sows have been chosen since they are kept for a longer period of time as compared with fattening pigs and therefore influencing factors from the housing environment may have a greater impact on them. Furthermore, leg health is a prerequisite for productivity and longevity. In the preparatory phase, different gait scoring systems were be identified from the literature and tested with regard to reliability and feasibility in the on-farm context. Also, farms which are willing to cooperate (criteria for inclusion: minimum flock size 20 sows, certified... |

| Ziel dieser Studie war die Überprüfung in wiefern sich zwei unterschiedliche Applikationsorte für eine subkutane Körpertemperaturmessung bei Ziegen eignen. Damit könnte die elektronische Tierkennzeichnung zur Krankheitsfrüherkennung und damit für die Tiergesundheit genutzt werden. Die eingesetzte Antenne war für die Erfassung der Körpertemperatur nicht geeignet, weil die Schwanzfalte belüftet wurde. Statt dieser Antenne wurde in den folgenden Versuchen ein Stick-Reader eingesetzt. |

| The aim of this study was to evaluate the influence of the rearing method on heart rates (as stress indicator) in the first days of lactation during milking. Heart rate was measured in two cows (K) and in eight heifers, four (F) reared with an automatic teat feeder, four (FKK) reared naturally by suckler- or foster cows. Heart rate was evaluated with a POLAR heart rate monitor on day one and nine of lactation during the milking procedure. The respective heart rates could be assigned to the events in the milking parlour via videoanalysis. Between the two heifer groups there were no physiologically relevant differences in heart rates on the two observed days. Both heifer groups showed higher heart rates on day one compared with day nine. Group K showed lower... |
