| Four groups of eight New Zealand hybrid rabbits were fed ryegrass meal only, alfalfa meal only, ryegrass and oats 1:1, or alfalfa and oats 1:1. Diets were offered ad libitum in pelleted form from 5-30 weeks of age, when they were slaughtered. Intramuscular fatty acid profiles were determined in the Musculus quadriceps of the left hindleg. Feed intake was not statistically different between the four groups, nor was carcass weight. The main effect of the forage-only diets on the fatty acid profiles was a decrease of monounsaturated and an increase of polyunsaturated fatty acid (PUFA) proportions. Within PUFA, the n-3 fatty acids more than doubled with forage-only compared to forage-oats diets, while the n-6 fatty acids slightly decreased. In general,... |

| Background • Nitrate leaching threatens both the environment and drinking water quality • Switzerland ca. 380,000 ha with > 25 mg nitrate/L in groundwater (quality criteria for drinking water) [1]; the Gäu region (Canton Solothurn) is especially vulnerable • Organic fertilizers (slurry, farmyard manure, etc.) might entail considerably increased leaching risks due to variable nitrogen (N) content and availability • Aim: increase N use efficiency, simultaneously reduce leaching |

| Jeweils sechs laktierende Brown Swiss Kühe erhielten entweder reine Weidefütterung, reine Grünfütterung im Stall oder eine konventionelle Silage-Kraftfutter Vergleichsration. Dies wurde nacheinander für jeweils 42 Tagen an einem raigrasreichen Talstandort (400 m) und auf einer extensiven artenreichen Alpweide (2000 m) durchgeführt. Die Konzentration an Tocopherolen (Vitamin E)in der Milch wurde mittels HPLC bestimmt. Die Vitamin E-Konzentrationen waren in den grasbasierten gegenüber den aus der Vergleichsration stammenden Milchproben generell deutlich erhöht. Einen weiteren geringen Zusatzeffekt für den Tocopherolgehalt der Milch brachte die Alpweide, wobei jedoch aufgrund der geringeren Milchleistung die tägliche Menge an mit der Milch sekretiertem... |
