| Hintergrund: Deckung des Bedarfes an Riboflavin (Vitamin B2) mit ausschließlich ökologisch erzeugten Futterkomponenten in der Aufzucht von Mastpoulets kritisch, da native Gehalte in Getreide und Leguminosen zu gering sind. Am Markt ist aktuell kein ohne Gentechnik hergestelltes Riboflavin verfügbar, daher sind Alternativen in Form von Riboflavin- haltigen Futtermitteln zur Aufwertung von Öko-Futtermischungen notwendig. |

| The effects of genotype and protein source on the performance of male layer hybrids compared to a fattening strain were investigated. The layer hybrids Lohmann Brown (LB, n = 90, male), Lohmann Selected Leghorn (LSL, n = 90, male) and the fattening hybrid Hubbard JA-757 (HUB, n = 90, mixed sex) were divided into three feeding groups: 1) commercial feed with 25,5 % soybean cake (Control), 2) control diet + alfalfa meal ad lib. (Alf-ext) and 3) control diet inclusive 12 % replace of soybean cake by alfalfa meal (Alf-int). Fattening periods were 63, 91 and 104 days for HUB, LB and LSL, respectively. Final weights were influenced by the interaction of genotype and feed (HUB 1843, LB 1871, LSL 1631 g). Highest daily weight gains showed HUB, followed by LB and... |

| The known influence of forage composition on fatty acid (FA) profiles in ruminants’ meat and milk may be different for other organs. Therefore, in the present study FA profiles of phospholipids in lung tissue, heart muscle and brain (medulla oblongata) were examined in growing Engadine and Valaisian Blacknose sheep grazing 4 pastures of different botanical composition, whereof three were extensively managed natural mountain swards. An intensively managed lowland pasture represented the control. On each pasture type, 6–7 lambs of each breed (54 in total) grazed for 9 weeks and were subsequently slaughtered. Tissue samples were taken at slaughter, homogenized and analyzed for FA profiles after phospholipid extraction. Response to the diets was tissue... |
