A 50-day feeding trial was conducted to evaluate the effects of yeast nucleotide in diets on growth performance, serum immune indices and muscle composition of Ancherythroculter nigrocauda (mean initial body weight, 23.30±0.59 g). Seven isonitrogenous (approximately 42.76% crude protein) and isoenergetic (17.43 KJ g−1 gross energy) experimental diets with varying levels of yeast nucleotide (0[c...

BACKGROUND In studies of adult humans and in animal models, dietary intakes of the macronutrients, particularly fat, are related to body composition; however, data on children are more scarce. OBJECTIVE We sought to determine whether diet composition is related to percentage body fat in children aged 1.5-4.5 y. DESIGN In 77 preschool children, a 4-d weighed-food record was used to determine...

BACKGROUND Providing of insufficient nutrients limits the potential growth of pig, while feeding of excessive nutrients increases the economic loss and causes environment pollution. For these reasons, phase feeding had been introduced in swine farm for improving animal production. This experiment was conducted to evaluate the effects of dietary energy levels and phase feeding by protein levels ...

previous work by other investigators indicates a direct relation between the amount of protein in the diet and the level of urea in the blood . however, the present report shows that the type of protein , apart from its level in the ration , also has an effect on blood urea concentrations. when adult male or female rats of two strains were fed a ration in which the only source of protein was wh...

Introduction: Non-alcoholic fatty liver disease (NAFLD) is considered to be a severe health threat across the world, the prevalence of which has significantly increased in recent years. Considering the role of diet in the pathogenesis of NAFLD, the present study aimed to evaluate and compare the dietary intakes of patients with NAFLD with healthy subjects. Methods:</str...

effect of dietary free l-lysine on growth, food intake, and muscle composition of beluga juveniles were investigated over 6 weeks. control diet lysine content was 2.1% of dry matter (4.4% of dietary protein). three experimental diets were prepared by adding lysine (0.5, 1 and 1.5%) to control diet to obtain diets containing 2.6, 3.1 and 3.6% of dry matter lysine (corresponding to 5.5, 6.6 and 7...

Effects of artificial diets on growth, spawning performance, egg and larval biochemical compositions and quality of Acanthopagrus latus in the Persian Gulf were studied. Nine diets representing a combination of three protein levels (40, 50 and 60%) and three energy levels (22.5, 23.5 and 24.5 MJ GE/Kg) were tested in triplicates. Each tank was stocked with 10 fish with a sex ratio of 1:1 and wi...

background: different studies have shown that inadequate and unbalanced intake of nutrients including micronutrient and macronutrient, have negative effects on exercise performance and optimal ability; besides, it decreases physical efficiency in athletes. the present study aimed to assess the nutritional status and body composition of female athletic students in isfahan university of medical s...

the present study was conducted to evaluate the effect of feeding of different levels of metabolizable energy and of different crude protein levels on the performance and blood factors in japanese quails in their 5 to 41d old. the experiment was conducted as a 3×5 factorial arrangement, in a completely randomized design of four replicates with 40 quails per replicate. the fifteen dietary treatm...
