It is well known that any quantitative (energy and protein levels) and qualitative (nature of the diet, nutrient dynamic) changes in the feeding of animals affect metabolism. Energy expenditure and feed efficiency at the whole-body level, nutrient partitioning between and within tissues and organs and, ultimately, tissue and organ characteristics are the major regulated traits with consequences...

Fungi contribute substantially to biogeochemical cycles of terrestrial and marine habitats by decomposing matter and recycling nutrients. Yet, the diversity of their planktonic forms in the open ocean is poorly described. In this study, culture-independent and molecular approaches were applied to investigate fungal diversity and abundance derived from samples collected from a broad swath of the...

The major contribution of poultry consumption in improving per capita nutrients level is well documented. Further improvement would be possible by lowering the prices at the consumer level and by improving the profitability of producers. First we highlighted the major problems in poultry production and then focused to estimate the percentage share of different stake holders in total profitabili...

In order to evaluate the response of major nutrients concentration, uptake and their efficiencies of isabgol (Plantago ovata) to N fertilizer combinations and irrigation regimes, a field experiment was conducted at the agricultural research farm of Shahrekord University, 2009. The experiment was arranged as split-plot, in randomized complete block design with three replications. The irrigation ...

Land application of poultry litter provides essential nutrients for hybrid bermudagrass [Cynodon dactylon (L.) Pers.] production, but ammonia (NH3) volatilization and N mineralization influence the amount of litter N available for plant uptake. Our objective was to determine the combination of broiler litter and fertilizer N, which maximizes the yields of forage and N, P, and K by ‘Coastal’ ber...

The purpose of this article is to examine dietary intake levels and major food sources of energy and nutrients for the Taiwanese elderly in order to relate nutrient intakes to food choices and to provide suggestions for dietary improvement. The data were derived from the 24-hour recalls from 1,911 subjects (955 males and 956 females) aged 65 and above, who participated in the Elderly NAHSIT car...

Goodman BE. Insights into digestion and absorption of major nutrients in humans. Adv Physiol Educ 34: 44–53, 2010; doi:10.1152/ advan.00094.2009.—Nutrient digestion and absorption is necessary for the survival of living organisms and has evolved into the complex and specific task of the gastrointestinal (GI) system. While most people simply assume that their GI tract will work properly to use n...

Poor quality infant and young child (IYC) diets contribute to chronic under-nutrition. To design effective IYC nutrition interventions, an understanding of the extent to which realistic food-based strategies can improve dietary adequacy is required. We collected 24-h dietary recalls from children 6-23 months of age (n = 401) in two rural agro-ecological zones of Kenya to assess the nutrient ade...

Arquitetura, s/n, Cidade Universitária, Recife, PE 50740-550, Brazil e-mail: [email protected] Knowledge of the seasonal variability of river discharge and the concentration of nutrients in the estuary waters of large rivers flowing into the tropical Atlantic contributes to a better understanding ...

Inconsistent results for the role of dairy food intake in relation to ovarian cancer risk may reflect the potential adverse effects of lactose, which has been hypothesized to increase gonadotropin levels, and the beneficial antiproliferative effects of calcium and vitamin D. Using data from the New England case-control study (1,909 cases and 1,989 controls), we examined dairy foods and nutrient...
