Contribution of direct-drinking water to calcium and magnesium and the influence on the height in school-age children.

Objective: To estimate the contribution of direct-drinking water provided in school to dietary intake (DI) and recommended nutrient intake (RNI) of calcium and magnesium, and to explore its influence on the height in school-age children.

Methods: Tap water and direct-drinking water samples were collected from schools in Taicang City to test the contents of calcium and magnesium, and compared by one-way ANOVA and test. Contribution rates of direct-drinking water to DI and RNI were calculated by using the contents of calcium and magnesium and data from the .

Effects of organic fertilizers on yield, soil physico-chemical property, soil microbial community diversity and structure of var. .

The amount of chemical fertilizer for vegetables is on the high level in China. The use of organic fertilizers to meet the nutrient requirement of crops will be an inevitable practice in sustainable agriculture. In this study, we compared the effects of pig manure fertilizer, rabbit manure fertilizer and chemical fertilizer on yield, quality of var.

Dietary Pattern and Dietary Energy from Fat Associated with Sarcopenia in Community-Dwelling Older Chinese People: A Cross-Sectional Study in Three Regions of China.

Associations between dietary patterns (DPs) and sarcopenia remain controversial, and fewer studies have mentioned the relationship between dietary energy composition and sarcopenia. The present cross-sectional study was conducted in three regions of China, to detect the associations between DPs and sarcopenia, and to identify the influencing nutrients. Exploratory factor analysis was conducted for DP identification.

Impact of molasses and microbial inoculants on fermentation quality, aerobic stability, and bacterial and fungal microbiomes of barley silage.

This study aimed to investigate the effects of microbial inoculants (L) and molasses (M) on the bacterial and fungal microbiomes of barley silage after the aerobic stage. The addition of molasses and microbial inoculants improved the aerobic stability of barley silage. The ML silage, which had a low pH value and high lactic and acetic acid contents, remained aerobically stable for more than 216 h.

Interaction effect of silo density and additives on the fermentation quality, microbial counts, chemical composition and in vitro degradability of rice straw silage.

This research evaluated the effect of molasses (M), cellulosic enzymes (E) and lactic acid bacteria (LAB) alone or in combination (M + LAB and E + LAB) on the fermentation quality, microbial counts, chemical composition and in vitro degradability of rice straw silages in different silo densities (200, 300, 400 and 500 kg/m). The M or E groups alone increased the dry matter (DM) losses at low silo densities. Acetic acid produced by LAB-related groups significantly inhibited yeast and mould at the silo density of 300 kg/m.

Dynamics of a microbial community during ensiling and upon aerobic exposure in lactic acid bacteria inoculation-treated and untreated barley silages.

This study investigated the effects of lactic acid bacteria on bacterial and fungal community during the fermentation process and aerobic exposure phase of barley ensiled with preparation of lactic acid bacteria (LAB). The inoculated silages displayed higher contents of lactic acid, acetic acid, and propionic acid as well as a greater number of lactic acid bacteria during ensiling. LAB-treated silage decreased the bacterial diversity during both ensiling and aerobic exposure but increased the fungal diversity during ensiling of barley.

[Accumulation of antibiotics, heavy metals and antimicrobial-resistant bacteria in duck bio-bed].

Objective: The objective of this study is to understand the accumulation of antibiotics, metals in the litter, and evolution features of bacterial antimicrobial-resistance during the fermentation of duck bio-bed.

Methods: The experiment was conducted in meat duck bio-bed farm of Jiangsu province from November 2011 to July 2013. The new litter and spent litter from 4th, 8th meat duck flock were studied for the accumulation of consumed antimicrobials and metals.
