| For alle mineralene unntatt klor var det et høgere innhold i 2. slått enn i 1. slått. Flere av planteprøvene viste så lavt innhold av ett eller flere makromineral at det antagelig reduserte avlingsnivået. Ut fra mineralbehovet hos sau og storfe viste plante- og blodprøver at flere av besetningene hadde liten tilførsel av svovel, fosfor, selen og E-vitamin, mens tilførselen av magnesium, kobolt og kopper var tilfredsstillende. Videre bearbeidelse av innsamla datamateriell og utprøving av ulike selentilskudd til jord og planter vil danne grunnlaget for å trekke endelig konklusjoner i forskningsprogrammet, samt utarbeide praktiske råd om mineraltilførsel til planter og drøvtyggere i økologisk landbruk. |

| Internal parasitic infection can pose major health problems in young livestock and this is particularly so in the context of lambs in organic production systems. In the context of sheep production on an organic farm the challenge to control parasite infection is especially difficult in situations where crop production is absent or a minor element of the whole farm system. Our investigations, to date at Athenry, have concerned an exploration of lamb production in an all-grass farming setting with particular attention being paid to the breeds employed and the seasonal patterns of gastrointestinal parasite challenge. This flock (about 110 ewes plus replacements) is wintered indoors and lambs in early March each year. |

| In der ökologischen Fischproduktion ist die Futtermittelherstellung streng reglementiert. Die für die Ernährung von carnivoren Fischarten wie der Regenbogenforelle (Oncorhynchus mykiss) hochwertigen Fischmehle dürfen gemäß den Produktionskriterien von NATURLAND lediglich aus nachhaltig zertifizierter Fischerei (z.B. MSC-Standard), aus Beifängen der Speisefischerei oder aus Überresten der Verarbeitung von ökologisch produzierten Fischen derselben geographischen Region bezogen werden. Aufgrund der begrenzten Verfügbarkeit soll die Fischmehlverwendung durch Nutzung alternativer Proteinquellen auf ein Minimum reduziert werden. Der Einsatz nativer pflanzlicher Mehle ist wegen der geringen Proteingehalte, möglicher limitierender Aminosäuren und antinutritiver... |

| The introduction of suckling systems in organic dairy calf rearing has the potential to enhance animal welfare in terms of ‘natural living’ and to live up to consumers’ expectations about organic agriculture. This study describes the implications of suckling systems in a practical organic dairy context. Results show that farmers can successfully develop and implement a suckling system in calf rearing. The consumption of mothers’ milk resulted in high weaning weights at 3 months of age. No immediate animal health problems linked to suckling systems occurred. Compared with traditional bucket feeding of milk, suckling systems resulted in increased natural behaviour such as calf cow bonding, natural sucking behaviour and care-taking behaviour. Some farmers... |

| Two different methods to reveal body condition scores (BCS), called independent BCS (iBCS) and dependent BCS (dBCS; similar to the method of Ferguson et al. 1994), were applied in 1111 Swiss Brown dairy cows. Ultrasound measurement of the back fat thickness (BFT) served as validation method. Aim of the study was to evaluate the impact of assessor’s subjective impression of the overall appearance of the cow on the scoring process. With 67.3% of the BFT variance, the dBCS with its consideration of the overall impression of the cow and its more open approach was more suitable to predict the subcutaneous fat appositions. The strictly formularized iBCS could only explain 47.3% of the BFT variance. The pin bone region was identified to cause the biggest... |

| Organic milk production varies due to topographical and structural farm conditions, but very little information is available about this variation in Germany. The aim of this study was to identify typical major farm types (MFTs) of German organic dairy farms and to describe their farm, herd, and management characteristics. Based on data from 204 organic dairy farms from previous studies with representative samples, fourMFTs were identified by cluster analysis. Cluster-criteria were herd size, milk yield, region, and housing system. Identified MFTs were (A) medium-scale herds with low-tomedium milk yield, (B) small-scale herds with low milk yield, (C) large scale herds with high milk yield, and (D) medium-scale herds in Southern Germany with medium milk... |

| Studies of organic farms in Norway have documented that cows in organic herds are less prone to milk fever compared to the overall average incidence of milk fever in Norway. Milk fever occurs most frequently in high-yielding cows, fat cows and older cows. On average, cows on organic farms are lower yielding, but also older. Dry cow diets relatively high in the anion chloride (Cl–) and low in the cations potassium (K+) and sodium (Na+) can prevent milk fever. In organic farming no inorganic fertilisers are used. This may result in low content of K in the plants and with that a low content of K in the fodder. Often there also is greater diversity of plants (clover, herbs, “weeds”) in an organic meadow than in a conventional meadow. Plants vary in their... |

| The objective of the present experiment was to study the need for the protein supplementation in the diet of growing dairy bulls (initial live weight 272 ± 28.5 kg and final live weight 666 ± 31.2 kg, on average) fed total mixed ration based on moderate digestible grass silage and barley. The experiment comprised 24 Finnish Ayrshire bulls and 8 Holstein-Friesian bulls and included four treatments. The control diet (C) consisted of moderate digestible (653 g digestible organic matter in dry matter (DM) grass silage (450 g kg-1 DM), barley grain (275) and barley fibre (275) without protein supplementation. Three isonitrogenous experimental diets included also extra protein, i.e. (1) rapeseed meal (RSM) (supplementation 530 g DM per animal day-1), (2) wet... |

| Production of organic growing pigs is characterized by indoor housing with access to outdoor concrete yards and feeding high amounts of supplementary feed based on grain and imported protein feed. However, this is not in accordence with the organic principles, which insist on optimization of nutrient recirculation, use of local renewable resources and animals being able to perform normal behaviour. The overall aim of the project was to contribute to development of an eco-efficent and trustworthy organic production system based on free-range growing pigs in pasture systems. The point of departure was to integrate the unique innate ability of pigs to forage above and below ground as a resource in the farming system. It was hypothesised that foraging in the... |

| Today in conventional food and feed production added vitamin B2 is produced almost exclusively from a GMO,1 namely the genetically modified Bacillus subtilis. Vitamin B2 applied in certified organic food and feed productions is an exception, as it is still synthesized conventionally. In fall 2007 and also recently, there has been a lack of non-GMO derived vitamin B2 on the European market, which has caused temporary supply problems for organic producers. This event triggered the political will to conduct new research in order to find alternative solutions for the substitution of synthetic vitamin B2 in organic agriculture. |

| Robust and competitive organic pig production needs to encompass low environmental impacts and good animal health and welfare. In theory, improving animal health and welfare reduces environmental impacts through decreased medicine use, improved growth rates and feed conversion efficiency. However, as data on environmental impacts are scarce, the extent of such improvement has never been verified on working farms. In organic pig production, health and welfare improvements must be implemented through preventive approaches, optimal disease management and innovative systems regarding outdoor areas. This poses a challenge to the farms. Together, organic regulations, different national welfare regulations and different building traditions have promoted the... |

| Rapporten omhandler den økologiske mjølkeproduksjonen på Tingvoll gard. Tingvoll gard ligger i Tingvoll kommune på Nordmøre og eies av Norsk senter for økologisk landbruk. Hele gården ble godkjent for økologisk drift i 1994. Siden 1996 har garden blitt drevet av et forpakterpar. Rapporten bygger hovedsakelig på data fra kukontrollen for perioden 1991-2013 og intervju med gardbrukerne. Mjølkekubesetningen består av rasen Norsk rødt fe (NRF). I 1991 var mjølkekvoten i overkant av 75 000 l. I 2006 gikk garden inn i samdrift med en annen gard og mjølkekvoten økte kraftig, og var nær 154 000 l i 2013. Arealet som drives av forpakterne ved Tingvoll gard var i 2013 280 daa fulldyrket areal og 80 daa innmarksbeite. Ved inngåelse av samdrift økte mjølkekvoten... |
