OBJECTIVE: To assess protein intake, its distribution across main meals and the relationship between this muscle mass in older adults. METHODS: This cross-sectional study included 47 adults attending a community center Campo Grande, MS, Brazil. A sociodemographic questionnaire was used to characterize population. Dietary intake data were collected using two 24-hour dietary recalls on nonconsecu...

background: the incidence of ulcerative colitis (uc) is rising in populations with western-style diet, rich in fat and protein, and low in fruits and vegetables. in the present study, we aimed to evaluate the association between dietary protein intakes and the risk of developing incident uc.   methods : sixty two cases of uc and 124 controls were studied using country-specific food frequency qu...

the study was conducted to determine the effect of varying protein levels and preservation method on external egg qualities of japanese quails. a total of 180 birds were randomly allotted into three dietary treatments in a completely randomized design (crd) replicated six times. a factorial arrangement of 3 × 4 × 4 which involves 3 protein levels (15, 20 and 25% crude protein), 4 storage method...

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...

phytate in poultry rations containing rice bran (rb) critically reduce poultry performance while increasing n and p excretion. the objective of this study was to determine whether the anti-nutritive problems associated with higher inclusions of rice bran in poultry rations (up to 40%) could be mitigated with mega doses of phytase. twenty days old male broiler chicks (n=180) in 60 floor pens wer...

the aim of this study was to compare the effects of two levels of crude protein using poultry by-product meals (pbpm) fed during late gestation on the performance, blood metabolites, and colostrum composition of holstein dairy cows. sixteen multiparous cows 26±6 d before expected calving were assigned randomly to two treatments containing 1) 14% and 2) 16% crude protein. the cow’s bcs was 3.56 ...

a crd experiment was conducted to study three different soybean meals on experimental qualitative properties, digestibility of protein and performance in broiler chickens for a 42 day period. a total of 195 day-old ross 308 male broiler chickens were randomly distributed to 3 dietary treatments with five replicates of 13 chicks each. to measure digestibility of protein, thirty 15-day-old ross 3...

A feeding trial was performed to evaluate the effects of dietary L-threonine supplementation on growth and body composition fingerlings Rhamdia quelen (initial weight: 4.47 ± 0.39 g). Five diets (370 g/kg crude protein 14.23 MJ / kg digestible energy) containing levels (16.0, 22.0, 28.0, 34.0, 40.0 g threonine/kg protein) were fed quadruplicate groups fishes for 10 weeks. The analysed variables...
