The aim of this study was to assess the prevalence of the major helminth infections affecting organic dairy cattle in northern Spain. Milk and faecal samples were obtained from 443 milking cows. Ostertagia ostertargi and Fasciola hepatica exposure was assessed by detection of specific antibodies in milk samples and F. hepatica infection was diagnosed by the detection of coproantigens in faecal samples. Dictyocaulus viviparus and Calicophoron daubneyi infections were diagnosed by conventional coprological techniques. The prevalence of infections caused by F. hepatica was considerable low, but similar to data reported from conventional farming in the same area. The prevalence rate of C. daubneyi infection was higher than previous data mirroring an increase... |

Buckwheat (Fagopyrum esculentum) has a high ecological value due to the long and intensive flowering as well as its favorable impact on soil fertility. However, in Europe demand for buckwheat kernels as food is low. Therefore, the question arises whether cultivation of this plant could be promoted by using it as animal feed. In the current preliminary experiment, the extent to which buckwheat, offered in different forms, is consumed by dairy cows was tested in conjunction with potential effects on milk yield. Three groups of lactating cows were fed a silage-concentrate mixture, which either contained 3 kg DM/d buckwheat kernel flour (n=4), or 2.5 kg DM/d buckwheat total plant silage (n=3) or no buckwheat compound (control; n=4). After 4 days of... |

The demand for information relating to the nutrition of horses in a cold environment is increasing with the popularity of loose housing of horses. This study examined the energy intake and growth of 10 weanling horses from November to March (22 weeks) in a loose housing system (paddock and insulated sleeping hall with deep-litter bed). The horses were measured weekly for body condition and body weight, and the feeding was adjusted according to a horse’s body condition. Metabolizable energy (ME) intake was compared to Finnish (MTT 2006) and Swedish (SLU 2004) nutrient requirements for 6–12-month-old horses. ME intake (75.5 ± 11.8 MJ d-1, mean ± SD) was on average 24.6% above the requirements. The intake varied in a non-linear fashion in the course of the... |

Skatole, one of the main causes of boar taint, derives from tryptophan in the large intestine and accumulates in the fat tissue of boars, thus decreasing meat quality. We hypothesize that energy of roughage promotes growth of skatole reducing microbes. Therefore, we compare the two roughages grass-clover-silage and straw, regarding the effect on concentrations of skatole and androstenone in the fat tissue. The experiments are currently ongoing and will help to evaluate special feeding strategies as an alternative to castration, thereby promoting animal welfare and product quality. |

Vitamin E is important for ruminants to maintain an optimal immune function, reproduction traits and a high quality of milk and meat. Synthetic vitamin E consists of 87.5% tocopherol molecules with a non-natural configuration and is biological ineffective. The aim of this project is to study the effects of supplementing the diets with seaweed meal or oil seeds extracts as natural vitamin E sources on the immune system and gastrointestinal microbiota in sheep and their off-springs. Of special interest is the group fed with seaweed meal, since seaweed is an abundant and easy accessible raw material on the Norwegian coastline with a huge economical potential. The study includes 40 ewes and their future lambs. The animals will be followed from mating until... |

Une alimentation exempte de concentrés a déjà fait l’objet de nombreuses études chez les vaches laitières, mais rares sont les études scientifiques menées sur l’élevage de veaux sans concentrés. Or, tous les manuels d’enseignement usuels préconisent l’utilisation de concentrés. Dans cette étude, les auteurs comparent deux groupes de sept remontes d’engraissement croisées brune × limousine. Durant les cinq mois de l’essai, chaque veau du groupe 1 a reçu près de 500 kg de lait et 141 kg de concentrés, contre environ 1100 kg de lait, sans concentrés, pour les veaux du groupe 2. Cette étude n’a montré aucune différence entre les deux groupes au niveau des gains journaliers, du poids au sevrage ou encore de l’état sanitaire ni même au niveau du comportement... |

Das hier beschriebene Verbundvorhaben umfasst folgende Teilprojekte: FKZ 11NA034, FKZ 11NA036 und FKZ 11NA059. Alle in Organic Eprints archivierten Projektbeschreibungen und Veröffentlichungen zu diesem Verbundvorhaben finden Sie unter folgendem Link: http://orgprints.org/cgi/saved_search?savedsearchid=1426. Das Ziel des Projektes ist die Bestimmung der Gehalte an verdaulichen Nährstoffen und umsetzbarer Energie sowie die Ableitung von Empfehlungen zur optimalen Einsatzhöhe von buntblühenden Wintererbsen aus ökologischer Erzeugung für Mastschweine. Durch den vergleichenden Einsatz von Sommererbsen und buntblühenden Wintererbsen soll überprüft werden, ob die Wintererbse dem Einsatz von Sommererbse gleichwertig ist oder anteilig ersetzen kann. Um die... |

Bu çalışmada, dış kaynaklı beyaz (Lohmann LSL) ve yerli kahverengi (ATAK-S) yumurtacı tavukların organik ve konvansiyonel sistemde yetiştirilmelerinin yumurta verim performansı, yumurta iç ve kabuk kalitesi, yumurtanın kısımları, protein oranı, kolesterol miktarı ile yağ asitleri kompozisyonu üzerine etkileri incelenmiştir. Her iki yetiştirme sistemde de beyaz yumurtacılar yerli kahverengi yumurtacılara kıyasla daha yüksek yumurta verim ve ağırlığına sahip olmuşlardır. Organik sistemde beyaz yumurtacıların yumurta verimi ve toplam yumurta sayısı düşerken, kahverengi yumurtacıların yükselmiştir. Beyaz yumurtacıların yaşama gücü kahverengi yumurtacılara kıyasla organik sistemde % 14 düzeyinde daha düşük olup, ölümler kanibalizmden kaynaklanmıştır. Organik... |

In a 7-week on-farm feeding trial rainbow trout(Oncorhynchus mykiss) were provided with a diet containing 28% mechanically de-fatted insect meal prepared from larvae of the black soldier fly, Hermetia illucens (HIM) and compared to a control that received a certified organic and fishmeal based diet. In the test diet insect meal replaced almost 50% of the fishmeal. The whole experiment was conducted under practical conditions on an organically certified rainbow trout farm in Switzerland. Fish of initially 66.5±2.3 g body weight were grown to 125±4.5 g and assessed for their growth performance, as well as analysed for their proximate composition, feed conversion ratio, fatty acid contents and organoleptic properties. Improved lipid utilisation and decreased... |

The aim of this study was to analyse the potential greenhouse gas emissions (GHGE) of locally and regionally produced, alternative protein‐rich feedstuffs (APRFs) which can be utilised in dairy cattle feeding as compared to extracted soybean meal (SBME) in a complete life‐cycle chain for Austria. In addition to GHGE from soil (N2O), from the production of mineral fertilizers and pesticides, industrial processes (oil milling, distillery, and drying plant) and use of fuels, the effects of land use change (LUC) were included in the calculation of GHGE. Currently, SBME, which is mainly imported from South‐America, is the most important protein feedstuff for livestock in Austria, but recently it was started to replace it by APRFs in diets for dairy cows for... |

En grøn foderration med brug af urter i græsblandingerne gør det muligt i højere grad at blive selvforsynende med vitaminer og mineraler. Et forsøg med to økologiske fodringsstrategier har vist, at køer der ikke får tilskud af mineraler, men derimod får en foderblanding med et højt indhold af naturlige mineraler og vitaminer, har samme foderoptagelse, mælkeproduktion og reproduktion, som køer på en mere traditionel foderration. Blodprøver viste desuden, at køer, der udelukkende fik mineraler og vitaminer naturligt indeholdt i de forskellige fodermidler, havde samme A- og E-vitaminniveau i blodet, som køer der fik tilsat mineralblanding til foderet. |

Die langfristige Konkurrenzfähigkeit der schweizerischen Milchproduktion wird von weiteren Kostensenkungen sowie einer hohen Qualität und Wertschätzung der Produkte abhängen. Bezüglich beider Zielsetzungen haben weidebetonte Produktionssysteme einen hohen Stellenwert. Auch andere Faktoren, die besonders bei der biologischen Wirtschaftsweise geltend gemacht werden, wie das Wohlbefinden der Tiere und die naturnahe Produktion sind Argumente für einen hohen Weideanteil in der Sommerfütterung. Allerdings ist die Nährstoffzusammensetzung einer reinen Grünfutterration meist nicht ausgewogen, ihre Verwertung deshalb nicht optimal. Eine geeignete Ergänzungsfütterung kann sich daher als sehr effizient erweisen, solange sie nicht in grösserem Ausmass den Verzehr von... |
