The reduction of copper-based plant-protection products with the final aim phasing out has a high priority in European policy, as well organic agriculture. Our survey aims at providing an overview current use these agriculture and need for alternatives to allow policymakers develop strategies complete out. Due lack centralized databases on pesticide use, our combines expert knowledge permitted real copper per crop country, statistics area. In 12 surveyed countries (Belgium, Bulgaria,...
A 2 × factorial continuous experiment was conducted with 28 Norwegian Red dairy cows in early lactation to compare milk content of phytoestrogens when feeding ad libitum white clover (WCS) or red (RCS) grass silages prepared from the second and third cut without 10 kg/d supplementation a standard concentrate. The were offered either RCS WCS for 88 d (period 1) thereafter mixed clover-white clover-grass silage 48 2). Total dry matter intake yield not affected by forage type but increased...
There is increasing concern that the intensification of dairy production reduces concentrations nutritionally desirable compounds in milk. This study therefore compared important quality parameters (protein and fatty acid profiles; α-tocopherol carotenoid concentrations) milk from four systems with contrasting intensities (in terms feeding regimens milking systems). The several (β-lactoglobulin, omega-3 acids, omega-3/omega-6 ratio, conjugated linoleic c9t11, and/or carotenoids) decreased...
Abstract Plant secondary metabolites (PSMs) may improve gastrointestinal health by exerting immunomodulatory, anti-inflammatory and/or antiparasitic effects. Bark extracts from coniferous tree species have previously been shown to reduce the burden of a range parasite in tract, with condensed tannins as potential active compounds. In present study, impact an acetone extract pine bark ( Pinus sylvestris ) on resistance, performance and tolerance genetically diverse mice Mus musculus was...
A major challenge in sheep farming during the grazing season along coast of south-western Norway is tick-borne fever (TBF) caused by bacteria Anaplasma phagocytophilum that transmitted tick Ixodes ricinus. study was carried out 2007 and 2008 to examine prevalence A. infection effect on weaning weight lambs. The included 1208 lambs from farms Sunndal Ram Circle Møre Romsdal County Mid-Norway, where ticks are frequently observed. All were blood sampled serum analyzed an indirect fluorescent...
Very little is known about the effects of an organic or conventional diet on animal physiology and health. Here, we report effect contrasting crop protection (with without chemosynthetic pesticides) fertilization (manure mineral fertilizers) regimes feed composition growth physiological parameters rats. The use manure instead fertilizers in production resulted lower concentrations protein (18.8 vs 20.6%) cadmium (3.33 4.92 μg/100 g) but higher polyphenols (1.46 0.89 g/100 feeds body (22.0...
It has been questioned if the old native Norwegian sheep breed, Old Norse Sheep (also called Feral Sheep), normally distributed on coastal areas where ticks are abundant, is more protected against tick-borne infections than other breeds due to a continuously high selection pressure pasture. The aim of present study was test this hypothesis in an experimental infection study.Five-months-old lambs two breeds, White (NW) and (ON) sheep, were experimentally infected with 16S rRNA genetic variant...
In this study, a brown macroalgae species, Saccharina latissima, processed to increase its protein concentration, and red Porphyra spp., were used evaluate their in vivo digestibility, rumen fermentation blood amino acid concentrations. Four castrated rams used, whose diets supplemented with protein-rich fraction of S. commercial spp. soybean meal (SBM). Our results show that the digestibility diet latissima extract was lower (0.55) than those (0.64) SBM (0.66). spite higher nitrogen (N)...
Utilisable crude protein (uCP), methane (CH4) production and other fermentation parameters were analysed in vitro for a diet which grass silage was replaced by different levels of seaweed fractions prepared from three species: Saccharina latissima, Alaria esculenta Palmaria palmata. Ten these species the content had been increased salt reduced simple processing tested, with inclusion based on nitrogen fractions. Following an extraction procedure, four one palmata, incrementally included...
Grass-clover silage constitutes a large part of ruminant diets in Northern and Western Europe, but the impact quality on methane (CH4) production is largely unknown. This study was conducted to identify attributes grass associated with variation CH4 yield. We expected that nutrient concentrations fermentation products would affect yield, these factors could be used predict methanogenic potential silages. Round bales (n = 78) grass-clover from 37 farms Norway were sampled, incubated, screened...
In this study, 200 Norwegian dairy farms were analyzed over three years to compare greenhouse gas emissions, nitrogen (N) intensity, gross margin, and land use occupation between organically conventionally managed farms. Conventionally farm groups constructed based on propensity matching, selecting the closest counterparts (n=15). These groups, each containing 15 farms, differentiated by an increasing number of matching variables. The first group was matched geographical location, milk...
Phytoestrogens have structures similar to endogenous steroids and may induce or inhibit the response of hormone receptors. The objectives present study were compare effects long-term vs. short-term grassland management in organic conventional dairy production systems, systems assess seasonal variation on phytoestrogen concentrations bulk-tank milk. phytoestrogens analyzed milk sampled three times two subsequent years from 28 farms: Fourteen (ORG) farms with either paired 14 (CON) respect...
