A current predominant paradigm emphasizes the role of epiphytic algae for invertebrates in most seagrass food webs. However, in some intertidal Zostera noltii beds, epiphyte biomass is very low compared to microphytobenthos and seagrass biomasses. We assessed the role of microphytobenthos in a temperate intertidal Z. noltii bed by combining stable isotope and fatty acid (FA) analyses on primary producers, composite sources suspended particulate organic matter (SPOM) and sediment surface organic matter (SSOM) and the main macrofaunal consumers. Z. noltii showed high delta C-13 (-9.9 parts per thousand) and high 18:2(n-6) and 18:3(n-3) contents. Microphytobenthos was slightly more C-13-depleted (-15.4 parts per thousand) and had high levels of diatom... |

ABSTRACT The present study evaluated the effects of aronia powder on growth performance and fatty acid profiles of ducks. A total of 90 ducks (one-day-old pekin, 48 males and 42 females) were distributed according to a completely randomized design into two treatments (control and 1% aronia powder) with 3 replicates of 15 birds per pen for 42 d. Apart from the feed:gain ratio, the other growth performance parameters, including initial body weight, final body weight, weight gain, and feed intake, did not differ significantly between treatments (p>0.05). In addition, there was no significant difference (p>0.05) in fatty acid profiles between treatments. However, oleic acid (C18:1), linoleic acid (C18:2), and polyunsaturated fatty acid (PUFA) were... |

ABSTRACT The purpose of this study was to evaluate the effects of three different forms (powder, pellet, and coated pellet) of red ginseng marc (RGM) and fermented red koji (FRK) feed additive on the blood parameters and fatty acid (FA) profiles of laying hens, after two months of dietary supplementation. A number of 240 40-week-old Hy-line Brown laying hens were randomly designated to four dietary treatments, each with six replicates of 10 hens each, in a completely randomized design. The control group was fed a basal diet, and the other three treatments groups were fed 1% RGM powder mixed with FRK, pellets of 1% RGM with FRK, and coated pellets of 1% RGM with FRK. The powder and coated pellet diets contained the lowest total cholesterol and glucose... |
