... Tetrapolar bioelectrical impedance analysis (BIA) offers the possibility of determining the bioconductor volume in discrete segments of the body, because the resistivities of bone, fat, and skeletal muscle differ considerably. We tested this hypothesis by measuring BIA and anthropometry of defined segments of the right thighs of women before and during a controlled weight-loss program. Eight women ...

Abstract:
... Distribution and development of fat, muscles, and bone were studied repeatedly by computer tomography from 4 to 17 wk of age in two commercial strains of turkeys (BUT-9 and Nicholas) of both sexes. Generally, the proportion of total fat and meat increased and bone decreased significantly throughout the experimental period for both strains and sexes. When compared at the same age or body weight, BU ...

Abstract:
... Objectives: To assess the effectiveness of biliopancreatic diversion (BPD) in the treatment of morbid obesity and to evaluate how the procedure affects body weight. Subjects: Fourteen morbidly obese subjects studied before and 30 months after BPD and fifteen healthy volunteers matched for age, sex and height (controls). Methods: Comparison of the following parameters were made in the study groups ...
Myotis lucifugus; adults; body composition; energy; food intake; gastrointestinal system; lactation; mammals; postpartum period
Abstract:
... Body composition of little brown bats, Myotis lucifugus was quantified to evaluate the proximate costs of reproduction in a small temperate mammal. Changes in the major components of body composition (water, lean dry, and fat mass) during the breeding season were analyzed in adult females and in young during the postnatal growth period. Changes in body composition of reproductive females were smal ...
... The effect of dietary phosphorus (P) concentration on faecal and non-faecal P excretion of rainbow trout was studied with P concentrations ranging from 1.0 to 6.2 g/kg dry matter, the upper level calculated to be slightly above the P requirement. Eight semi-purified diets were prepared with varying proportions of dibasic sodium phosphate and an inorganic binder to achieve intended P concentrations ...

Abstract:
... A 7-week feeding experiment was conducted to determine the optimum feeding frequency for growth, body composition and gastric evacuation of the juvenile Korean rockfish. Three replicate groups of the fish (average weight of 5.7 g) were fed to visual satiety either dry pellets (DP) or moist pellets (MP), at different feeding frequencies (two meals a day, one meal a day or one meal every 2 days). At ...

Abstract:
... Essentiality of dietary calcium (Ca) supplement was investigated in fingerling scorpion fish. Four purified diets were formulated with supplementation of 0.2% Ca from Ca-lactate, no supplemental Ca, and 0.2 and 2.5% Ca from tricalcium phosphate (TCP), respectively. Each experimental diet was fed to three replicate groups of fish (mean weight, 0.8 g) for 12 weeks at a water temperature of 24 +/- 0. ...

Abstract:
... Atlantic salmon with an average initial weight of 180 g were fed either a control diet containing 25% fish oil or a diet with 15% fish oil and 10% of an oil based on medium-chain fatty acid triglycerides (MCTs). The fish were kept in tanks supplied with saltwater for 65 days. The fish group with the lowest feed intake determined feeding level in the remaining groups. Exchanging 1/3 of the dietary ...

... An experiment was conducted in order to assess the incorporation in diets for juvenile turbot of extruded lupin (Lupinus albus) and heat-treated (RM1) or untreated (RM2) rapeseed meals (Brassica napus) (26 and 40 micromol glucosinolate/g DM, respectively). The level of incorporation of 30% for each plant-protein, as well as 46% for RM1 and 50% for lupin was tested and compared with a fish meal bas ...

Abstract:
... In an effort to reduce fish meal (FM) use in diets for sunshine bass, a feeding trial was conducted. Four practical floating diets were formulated to contain 40% protein, similar energy levels, and without FM. A fifth diet was formulated to contain 30% FM and served as the control diet. Ten fish were stocked into each of 20 110-l aquaria and were fed twice daily (0730 and 1600 h) amounts of diet s ...

Abstract:
... The proximate (% of dry weight), amino (% of total amino acids) and fatty acid (% of total fatty acids) profiles of tissues (muscle, hepatopancreas, hemolymph and exoskeleton) of American lobster, Homarus americanus (Milne Edwards) affected with shell-disease, were compared with those of healthy, unaffected animals. Muscle tissues of affected lobsters had significantly lower levels of carbohydrate ...
