The aim of this study was to evaluate the potential health benefits of onions consumed at two levels of intake, using the pig model. The dietary fat content was set at a level typical of a “western” diet (25% w/w). Fifteen female and fifteen male pigs (Large White × Landrace) were allocated to one of three dietary treatments in a randomised block design. Treatments consisted of control diet (no onion) and onion supplementation at either 8.6 or 21.4 g of onion/MJ DE fed for six weeks. Onion consumption reduced plasma triglyceride levels by 15% (P=0.030) regardless of sex and onion dose. Total plasma cholesterol and cholesterol fractions were unaffected by onion supplementation (P > 0.050). The bioactivity of onion was evident in haematocrit measures, where red blood cell and haemoglobin were significantly reduced in a dose dependant manner (P < 0.001 and P=0.011, respectively), while other cell counts, with exception of segmented neutrophils (−18%, P=0.012), were largely unaffected. Serum oxidative status was improved (P=0.007) in pigs consuming onions. These data demonstrate that consumption of onions can have positive health effects in both male and female pigs consuming a high fat diet. 相似文献

Duplicate groups of tench (Tinca tinca) juveniles (mean weight 0.69 g) were fed at 28 °C for 70 days either a commercial formulated diet, Futura, or frozen Chironomidae
larvae at four levels: below satiation, at about satiation, above satiation and well above satiation. These are represented
by the feeding groups F1–F4 and C1–C4, respectively. No mortality was observed throughout the experiment. In groups F2–F4
a considerable incidence of uneaten food (>40% observations), deformities of the caudal penduncle, retarded growth, elevated
condition coefficient (>1.2), reduced amounts of minerals in the tissue (<10% dry matter), high C/N ratio (>5) and high caloric
value of the tissue (>28 J mg−1 dry matter) (the latter two suggesting excessive fat deposits), were found. The combination of these indices was indicative
of overfeeding in fish fed the Futura diet at the daily doses ≥2.7% fish biomass. First symptoms of overfeeding: a considerable
incidence of uneaten food, retarded growth, and elevated C/N ratio were observed in the group fed Chironomidae larvae at the
highest level, (C4, wet Chironomidae 20.7% of the fish biomass daily, that is, 3.9% of dry chironomids per fish biomass and
day). Thus, restricted daily doses of formulated diet not exceeding 2.5% fish biomass are recommended for tench juveniles
aged 130–200 days post hatch. Safe daily doses of frozen Chironomidae (in terms of larvae dry weight) remain below 3.5% of
fish biomass. 相似文献
