Larger serving sizes and more frequent eating episodes have been implicated in the rising prevalence of obesity at a population level. This study examines the relative contributions of meal size and frequency to weight gain in a large sample of British children. Using 3-day diet diaries from 1939 children aged 21 months from the Gemini twin cohort, we assessed prospective associations between m...
A 12-week feeding trial was carried out to assess the effect of fish meal replacement by earthworm meal (Eiseniafoetida) on growth performance, feed efficiency and carcass composition of Siberian sturgeon (Acipenserbaerii). Fish with mean weight 21.32 ± 1.91 (mean ± SD) were fed with five experimental diets which 0% (Control), 10% (EWM10), 20% (EWM20), 30% (EWM30) and 40% (EWM40) of fish meal p...
A killifish species Aphanius ginaonis occurs in Geno hot spring is one of the unique fish species that could successfully survive and acclimated to the high temperature of hot springs. In this study, we investigated the effects of Geno's cyanobacteria extracts on growth, survival and morphology of gill tissue in Aphanius dispar exposed to normal temperature and long-term thermal stress. For thi...
in order to investigate the effects of artichoke leaf powder and vitamin eon performance, internal organs relative weight and some blood parameters, 240 day-old quails were assigned to four treatments including, basal diet (control), basal diet supplemented with levels of 1.5 and 3 percent of artichoke leaf powder and basal diet supplemented with 300 mg/kg diet vitamin e with four replicates an...
In this study, the effect of the color of the bedding of cultivating aquariums (white, black, green, blue) on growth performance, nutrition and biochemical composition of the body of large freshwater shrimp (Macrobrachium rosenbergii) post larvae was investigated. All laboratory and experimental stages of this study were carried out in the fall of 1397 and for 60 days in an ornamental fish plan...
In this study, effect of replacement of fish meal by Poultry by product meal on growth index, biochemical and immune parameters of Huso huso with average weight 108.83±5. 9gr ± SD that reared in fiberglass tank (2000 lit) for 8weeks were investigated. Six test diets (contain 42% protein and 18.5 Mj kg-1 energy) were prepared. Fish meal substituted by poultry by product at 20% (PBM20), 4...
the effects of probiotics and antibiotics and fat type in diet on broiler performance were studied by using 900 one-day old ross 308 chicks in a three × three factorial arrangement with three types of fat (nonfat, three percent fatty acid and three percent soy oil) and three growth promoters (without gp, flavomycin and protexin) in completely randomized design with four replicates per each trea...
Growth rate of 60 Lori-Bakhtiari single male lambs were assigned to a completely randomized design with two factors. The factors were tail status (with and without fat tail) and fattening period ( 75,90, 105 days). Lambs were alternately docked by the use of rubber rings at the begining of the second day of birth. Lambs were weaned at 90±5 days of age and randomly divided into three groups...
objective: this study was conducted to evaluate the effects of different proportions of marshmallow extract (althaea officinalis l.) on growth performance and carcass composition of common carp (cyprinus carpio). methods: common carp with an average weight of 37.65 ± 4.40 g were fed for two months with a diet supplemented with marshmallow (a. officinalis) extract 0.25%, 0.50 and 1%, and with no...
a 6 week study was conducted to assess the effects of wood betony (wb), stachys lavandulifolia extract on growth performance, hematological and biochemical parameters of common carp, cyprinus carpio. different levels of the wb extract (0, 2, 4 and 8 % weight per weight, w/w, 0wb, 2wb, 4wb and 8wb) in the diet were used. the results showed that final weight and weight gain were significantly imp...
