this study was undertaken to evaluate the effect of hydrolysable tannin (ht) and condensed tannin (ct) on growth performance and body composition of nile tilapia. hydrolysable tannin and ct were included into diets at four levels (0, 5, 15, and 25 g kg-1 diet). the diet with zero tannin level acted as control and the response of fish fed diets containing tannin was compared to that of the contr...

The present study was aimed at investigating the adverse effects of dietary zearalenone (ZEA) (1.1 to 3.2 mg/kg diet) on serum hormones, morphologic and apoptotic measurements of genital organs in post-weaning gilts. A total of twenty gilts (Landrace×Yorkshire×Duroc) weaned at 21 d with an average body weight of 10.36±1.21 kg were used in the study. Gilts were fed a basal diet with an addition ...

a total of 240, one-day-old quail chicks (coturnix coturnix japonica) were used to study the effects of artichoke leaf meal (alm) and vitamin e in diet on growth performance, ileal microbial populations and intestinal morphology in a 42-d trial. this experiment was performed as a completely randomized design with 4 replicates of 15 quails each, using a 4 × 2 factorial arrangement with diet and ...

In the present in vitro study, the effects of pH and ionic strength on the release of iron from pectin and the ability of pectin to reduce ferric iron to ferrous iron were examined. The bioavailability of Fe bound to pectin was evaluated in rats. The amount of Fe released from pectin was at a maximum at pH 2·0 and decreased as the pH value increased. At pH 2·0, the amount of Fe released from pe...

BACKGROUND Androgen levels in the prostate may influence carcinogenesis in this organ. Inhibitors of the enzyme 5alpha-reductase block conversion of testosterone to the more active androgen dihydrotestosterone. The use of a 5alpha-reductase inhibitor, finasteride, in the chemoprevention of prostate cancer is being evaluated in a clinical trial. PURPOSE This study was conducted to determine if...

The study was composed of two parts. A one-factor design was adopted to investigate DMD, CPM, NDFD and ADFD of diet by total feces collection method in trial one. Twelve lambs were allotted randomly to 4 groups of 3 animals (replicates), which were fed with basal diet, basic diet plus 40 mg/kg urease inhibitor, urea diet, urea diet plus 40 mg/kg urease inhibitor. Experimental period consisted o...

The effect of fish consumption on plasma lipoprotein subfraction concentrations was studied in 22 men and women (age > 40 y). Subjects were provided an average American diet (AAD, 35% of energy as fat, 14% as saturated fat, and 35 mg cholesterol/MJ) for 6 wk before being assigned to a National Cholesterol Education Program (NCEP) Step 2 high-fish diet (n = 11, 26% of energy as fat, 4.5% as satu...

________________________________________________________________________________ Abstract In this study dietary boron at different doses (0, 25, 50, 100 and 200 mg/kg feed) was supplemented to layers from 4 to 64 weeks of age. There was no significant difference between treatments with respect of mortality, egg production, egg weight, egg mass and cracked eggs. Significant increases were observ...

1. Rachitic bone lesions may be produced in rats by a diet containing an excess of calcium, but deficient in phosphates. 2. Similar lesions follow a diet deficient in calcium, but containing an excess of phosphates. The endochondral lesions, however, are less pronounced. 3. A diet deficient in both calcium and phosphate induces atypical rickets. 4. Inorganic salts other than calcium or phosphat...

Recovery from Mg deficiency was studied in adult Wistar rats fed a semisynthetic diet containing 0.04% Mg in the form of magnesium carbonate. Daily administration of a diet containing recommended levels of calcium carbonate to Mg-deficient rats led to the recovery, within the first seven days of treatment, of normal values in most of the parameters studied: gain in weight/day, and Mg retention ...
