Improved feed efficiency is a primary goal in dairy production to reduce feed costs and negative impacts of production on the environment. Estimates for efficiency of feed conversion to milk production based on residual feed intake (RFI) in dairy cattle are limited, primarily due to a lack of individual feed intake measurements for lactating cows. Feed intake was measured in Holstein cows durin...

BACKGROUND Patients with thalassemia have low circulating levels of many nutrients, but the contribution of dietary intake has not been assessed. OBJECTIVE Our objective was to assess dietary intake in a large contemporary sample of subjects with thalassemia. DESIGN A prospective, longitudinal cohort study using a validated food frequency questionnaire was conducted. PARTICIPANTS/SETTING ...

the intakes usually have been used in water distribution networks, irrigation channels, sewage networks, and the water/wastewater treatment facilities, etc. lack of sediment control entered to the intake channel is the main reason of entering sediments to the installation systems, which makes many problems for different parts. due to suspended particles in water, the facilities used such as pum...

The site of intestinal fat delivery affects satiety and may affect food intake in humans. Animal data suggest that the length of the small intestine exposed to fat is also relevant. The aim of the present study was to investigate whether increasing the areas of intestinal fat exposure and the way it is exposed would affect satiety parameters and food intake. In the present single-blind, randomi...

BACKGROUND Vitamin D insufficiency (defined as 25-hydroxyvitamin D [25(OH)D] concentrations <40 nmol/L) may be associated with subclinical adverse effects on bone mineralization. The current vitamin D status of children and adolescents in Canada has not been described. The purpose of this study was to describe the association between 25(OH)D serum concentration and dietary vitamin D intake, and...
