The Effects of Dietary Phosphorus on the Growth Performance and Phosphorus Excretion of Dairy Heifers
Heifers Growth Performance Phosphorus Phosphorus Excretion
2016/7/27
The objective of this study was to investigate the effects of reducing dietary phosphorus (P) on the frame size, udder traits, blood parameters and nutrient digestibility coefficient in 8- to 10-month...
Ultra-long–term human salt balance studies reveal interrelations between sodium, potassium, and chloride intake and excretion
sodium salt chloride potassium aldosterone urine diet electrolyte intake
2018/11/30
Background: The intake of sodium, chloride, and potassium is considered important to healthy nutrition and cardiovascular disease risk. Estimating the intake of these electrolytes is difficult and usu...
The Effects of Different Copper (Inorganic and Organic) and Energy (Tallow and Glycerol) Sources on Growth Performance, Nutrient Digestibility, and Fecal Excretion Profiles in Growing Pigs
Growing Pig Copper Energy Source Digestibility Fecal Excretion
2016/5/4
This study was conducted to determine the effects of different copper (inorganic and organic) and energy (tallow and glycerol) sources on growth performance, nutrient digestibility, gas emission, diar...
Growth, Bone Mineralization and Mineral Excretion in Broiler Starter Chicks Fed Varied Concentrations of Cholecalciferol
Non-phytate Phosphorus Bone Mineralization Mineral Retention
2016/4/25
An experiment was conducted to study the growth performance, bone mineralization and mineral excretion in broiler starter chicks fed high levels of cholecalciferol (CC) at sub-optimal levels of calciu...
Respiration, calcification, and excretion of the invasive slipper limpet, Crepidula fornicata L.: Implications for carbon, carbonate, and nitrogen fluxes in affected areas
Respiration calcification excretion invasive slipper limpet Crepidula fornicata L. Implications for carbon carbonate nitrogen fluxes
2014/5/5
We measured in situ respiration, calcification, and excretion of the slipper limpet, Crepidula fornicata L., and considered both seasonal variations and individual size, to estimate the effects of thi...
Nutrient excretion by fish in wetland ecosystems and its potential to support algal production
Nutrient excretion support algal production
2014/4/23
We used both direct measurement and bioenergetic methods to examine nitrogen and phosphorus (P) excretion
by fathead minnows in two wetlands over 2 yr. We also assessed the potential importance of nu...

Ammonium excretion by Antarctic krill Euphausia superba at South Georgia
Ammonium excretion Antarctic krill Euphausia superba South Georgia
2014/6/17
Excretion by Antarctic krill Euphausia superba (hereafter ‘‘krill’’) is measured typically in small containers of filtered seawater for 12-24 h, which may cause a reduction of swim...
