| 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... |

| 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... |

| Weaning of goat kids is in many cases a psychic and physiological strain for both, kids and dams. Frequently goat kids suffer from a decline of performance, e. g. of weight gain. An alternative could be a gradually weaning considering colostral period of 1 week as well as feeding whole milk according EU-Organic-Farming regulation for a period of 45 days. The aim of the study was to compare abrupt weaning (ML) after 45 days of mother bonded rearing with restricted suckling (RL) three times per day before weaning. As a method to asses stress responses in goat kids, heart rate variability (HRV) was measured as basal values before and after weaning. The results show that the overall variability (SDNN) of heart rate variability (HRV) for RL was significantly... |

| Kurzfassung zu Teilprojekt 1: Im Rahmen einer Untersuchung im Bundesprogramm Ökologischer Landbau mit dem Thema „Optimierte Kälbergruppenhaltung in der Ökologischen Milchviehhaltung“ (Projektnummer 02OE057) wurde eine Teiluntersuchung zum Status-Quo der Ökologischen Kälberhaltung in der Praxis durchgeführt. Ziel war die Erfassung von Kenndaten, die Ermittlung etwaiger Problembereiche und daraus die Ableitung von Handlungsbedarf. Es wurde eine zweistufige Vorgehensweise gewählt. In einem ersten Schritt wurden schriftliche Fragebögen von 323 Milchviehbetrieben ausgewertet. Im Hauptteil der Untersuchung wurden genauere Erhebungen auf 100 Praxisbetrieben in ganz Deutschland durchgeführt (Management, Haltung, Fütterung, Leistungen / Gesundheit, sowie... |

| Group housing is a natural and economic way of raising calves. One major disadvan-tage of group housing calves is the occurrence of cross-sucking as an abnormal behaviour. The main objective of our study on organic calf housing was the reduction of cross-sucking related to milk feeding. A new feeding stall with automatic gates was attached to an automatic teat feeder. One gate opened to an enriched area immedi-ately when the calves had finished their milk meal. In this zone calves could use rub-ber teats or a hay net (treatment optimized). The design for the control group used a simple feeding stall without attached enriched zone. 168 female calves (German Holstein) from one origin (herd) were randomly assigned to 14 groups with 12 calves each. Thus, each... |

| In contrast to the increasing demand for dairy goat products in Germany, a market for goat kid meat as a related product is more or less non-existing. Thus, the objective of our study was to develop a concept for organic goat kid meat production for dairy goat farms. In collaboration with a wholesaler, organic dairy goat farmers and marketing research the experimental part of our study was to find out if cross-breeding of meat-goats could improve meat quality and performance of fattening goat kids together with other factors like concentrate ratio of the diet, housing system as well as raising strategy. First results indicate that a low input level of concentrates of 10 % of total dry matter intake per goat kid and year is not sufficient to meet the... |

| To assess animal behaviour of goat kids on pasture, a real time positioning system, Ubisense 7000, was installed mobile and outdoors. One major goal of the study was to analyse time goat kids spent in functional areas like pasture, fodder hedges or hutch, the other goal was the feasibility of the positioning system regarding positioning of goats on pasture. Results show, that grazing periods happen even during the night, whereas fodder hedges were used only during daytime. Accuracy of the positioning concerning Euclidian geometry was around 15 cm, which is according manufacturer’s data. |

| More than a third of the world's grain harvest is used to feed animals. According to the environmental agency of the UN, losses of calories by bad conversion factor of grain into animal food could theoretically feed 3.5 billion people. This shows that the production of animal protein is very energy consuming, especially when concentrates are fed to ruminants. Until today feeding of ruminants even in organic dairy farming is based on concentrates, accepting overexploitation of resources and negative effects on animal health. In contrast to the received opinion of “a lot helps lot”, organic dairy production in Western Europe is trying to do the very reverse: Feeding less concentrates. This is in line with the evolution of ruminants to an excellent roughage... |

| 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. |
