| Der Zeitraum der ansteigenden Milchleistung nach dem Kalben birgt ein höheres Risiko, dass die Tiere an Stoffwechselstörungen oder Mastitis erkranken. Die rechtlichen Regelungen für den ökologischen Landbau verschärfen dieses Risiko durch die Limitierung des Kraftfuttereinsatzes, fordern aber auch von den Landwirten mit Hilfe angepasster Rassen, dieses Problem anzugehen. Die vorliegende Studie zielte auf den Vergleich von zwei verschiedenen Rassen, die unter den gleichen Managementbedingungen gehalten wurden und einem Vergleich von zwei Betrieben, die zwar die gleiche Rasse hielten, sich aber im Management unterschieden. Es sollte geprüft werden ob die Rasse oder das Management entscheidender für den Eutergesundheits- und Stoffwechselstatus der Kühe in den... |

| The long-term monitoring Trenthorst, situated near Lübeck in a temperate maritime climate on loamy soils, was established in 2003 and compares two cash crop and three livestock farming systems. We studied the soil mineral nitrogen contents of one cash crop and two livestock farms, specialised in dairy cows and goats/oilseeds resp., with the hypothesis that the livestock farms show a more even course of Nmin in the rotation and a higher rotation mean. The rotation average of Nmin in the cash crop farm was not lower than the ones in the livestock farms. But in the course of the rotations differences became evident: compared to the livestock farms the cash crop farm showed higher Nmin-values after the first rotation year (mulched vs. cut grass clover) but... |

| Although the crop rotation is an essential element of organic farming, only few long-term trials exist which compare different crop rotations under temperate climate. The long-term monitoring Trenthorst was established in 2003 and comprises the different crop rotations of two cash crop farms and three livestock farms specialised in dairy, pigs and goats/oil seeds respectively. In addition to the comparison of crop rotations under practical farm conditions the long-term monitoring study aims to analyse the development of soil parameters, yields and crop qualities after the conversion to organic agriculture. On each arable field four monitoring points were established, where the relevant parameters are measured. The yields of the first three years are... |

| The objective of this study was to compare the breeds German Holstein (HF, 30 animals) and German Red Pied (dual purpose) (RBT, 33 animals) in terms of milk yield, BCS and weight and the fat-protein ratio in milk during the first five weeks of lactation. HF had a higher mean daily yield than RBT (28.7 vs. 24.3 kg ECM). The mean dry matter intake of the mixed ration was 1 kg/d higher for the HF than the RBT, but this additional energy intake could not compensate fully the higher energy output via milk. Therefore the HF had a more negative energy balance than the RBT, but the expected higher loss of BCS or weight was not observed. Both breeds lost a mean of 0.2 BCS-points. A possible reason for this might be breed differences in the distribution of... |
