A study was conducted to determine the additive effects of calcium (Ca) levels and the enzyme phytase, organic acids (citric, ascorbic acid), vitamin D on broiler performance and nutrient digestibility (d 3 1 to 21) in wheat-based diet. Broilers were fed the following diets at either 7.9, or 9 g/kg of dietary Ca with: 1) a negative control wheat-based diet, 3.15 g/kg available phosphorus (P) (N...

Dietary uptake could be the primary route of arsenic (As) bioaccumulation in marine fish, but the bioavailability of inorganic and organic As remains elusive. In this study, we investigated the trophic transfer and bioavailability of As in herbivorous rabbitfish Siganus fuscescens and carnivorous seabass Lateolabrax japonicus. Rabbitfish were fed with one artificial diet or three macroalgae, wh...

We used a novel study design to measure dietary organophosphorus pesticide exposure in a group of 23 elementary school-age children through urinary biomonitoring. We substituted most of children's conventional diets with organic food items for 5 consecutive days and collected two spot daily urine samples, first-morning and before-bedtime voids, throughout the 15-day study period. We found that ...

Two experiments were conducted to investigate the feeding value of wood vinegar in weanling pigs. In Experiment 1, weanling pigs (n = 224; Landrace×Yorkshire×Duroc, 21±3 d-old, initial BW 6.12±0.10 kg) were assigned to four dietary treatments. Different levels of wood vinegar were added to the diets as dietary treatments (0, 0.1, 0.2 and 0.3%). Each treatment comprised 4 replicates with 14 pigl...

a eight-week trial was carried out to investigate the effects of various levels and type of organic selenium as compared to inorganic selenium. total of 81 layer hens (lsl) 35 weeks of age were used in a randomized complete blocks with 9 treatments, 3 replications of 3 birds per experimental unit. treatment diets included control 0/3 mg/kg sodium selenite and selenium yeast, (250 mg/kg, 500 mg/...

18 Producing organic fish diets requires that the use of both fish meal and fish oil is minimized 19 and replaced by sustainable, organic sources. The purpose of the present study was to 20 replace fish oil with organic oils and evaluate the effects on feed intake, feed conversion 21 ratio (FCR), daily specific growth rate (SGR) and nutrient digestibility in diets in which fish 22 meal protein ...

Over the last century, intakes of omega-6 (ω-6) fatty acids in Western diets have dramatically increased, while omega-3 (ω-3) intakes have fallen. Resulting ω-6/ω-3 intake ratios have risen to nutritionally undesirable levels, generally 10 to 15, compared to a possible optimal ratio near 2.3. We report results of the first large-scale, nationwide study of fatty acids in U.S. organic and convent...

Mediterranean diets are promising sustainable food models and the organic food system may provide health and environmental benefits. Combining the two models could therefore be a favourable approach for food sustainability. The aim of this study was to draw up a comparative description of four diets differing in the level of organic foods consumption and the adherence to the Mediterranean diet,...
